Greek Scientist Proved Archimedes Could Have Destroyed Roman Fleet by Solar Power

September 7, 2023

This is awesome! I’m reading John Freely’s The Flame of Miletus about the origins of science in ancient Greece and how it was preserved, transmitted and expanded by medieval and Renaissance Christian and Muslim scientists, mathematicians and philosophers. I’ve just come to the section about Archimedes, famous for his principle and for shouting ‘Eureka’ when he discovered it while having a bath. But he was also responsible for many other scientific and mathematical discoveries and inventions. He was a resident of Syracuse, a Greek colony that was invaded by the Roman general Marcellus in 212 BC. According to historians, Archimedes helped try to fight of the Roman invaders by setting their ships alight with rays from the sun reflected off the Greek soldiers’ burnished shields. Freely, however, states that it was mirrors. In 1975 the Greek scientist Ioannis Saccas proved that this was no mere myth with an experiment at the Greek naval bases at Skaramangas near Athens. He used mirrors to focus the sun’s rays on a replica trireme 50 metres away so that it burst into flames.

Who needs laser weapons?

I distinctly remember that a team of archaeologists and engineers tried a similar experiment in the 1990s in a British pop-science series, Ancient Engineering.

In maths, Archimedes also used methods which are now part of integral calculus. Calculus was discovered independent in the 17th century by Newton and the German philosopher and scientist Leibniz. Newton said that we see further, but we’re dwarves standing on the shoulders of giants. Other philosophers and scientists said the same in the Middle Ages, and when you read of scientific feats like that – which read as though they come from historical science fiction rather than fact, you feel the force of it.

What would the Greek philosophers and the medieval Christian and Muslim successors have been capable of, if they had had access to our modern scientific instruments?

I found the video below demonstrating the possibility that Archimedes’ death ray actually worked on the Greenpowerscience channel on YouTube. Hosted by Dan and Denise Rojas, they demonstrate how an array of flat metal mirrors can set a model ship alight using the sun’s rays. They discover, however, that you need flexible mirrors to get the focus just right. Previous experiment didn’t do this, and got poor results. But the two are able to set alight the model ship, its sail, its model crew and the table it rests on from meters away.

I really do wish we’d covered stuff like this in physics when I was at school.

Reply from Local Labour MP Karin Smyth on Fracking

November 4, 2022

A little while ago one of the internet petitioning organisations email me to request that I, and no doubt thousands of others, write to my MP to object to Liz Truss’ wretched plans to bring back fracking. I had absolutely no problem doing so, not least because one of the areas scheduled for it is in Keynhsam, a small town between Bristol and Bath. Today I got a very kind reply from here detailing her opposition to it and support for a sprint to Green energy. The email runs

‘Dear David

Thank you for contacting me about fracking.

I agree with you on this important issue. Fracking is unsafe, will not help our energy security or cut bills and is opposed by local communities.

I am pleased that the new Prime Minister has restored the ban on shale gas fracking in England. I find it extremely concerning, however, that this Conservative government previously broke its manifesto commitments in order to pursue a damaging policy that put the interests of fossil fuel companies above those of the British people.

To truly deliver energy security and lower bills, I believe we need a green energy sprint. The current crisis is a fossil fuel crisis and we cannot escape it by doubling down on fossil fuels. Renewables are today nine times cheaper than gas. The only way to cut energy bills and have energy security is with zero-carbon home-grown power, including by quadrupling our offshore wind capacity, more than doubling onshore wind and more than tripling solar by 2030.

I also agree that we need to prioritise and fund energy efficiency, which is why I support proposals for a national effort to bring all homes up to energy performance certificate band C within a decade. This would save families large amounts each year on their energy bills and reduce national gas imports by up to 15%.

Only Labour will consistently deliver promises to tackle the climate crisis and improve green energy. Please be assured that in the meantime I will continue to press the Government on this issue, as well as support calls to accelerate efforts on energy efficiency and homegrown renewables.

Thank you once again for contacting me.

Yours sincerely

Karin Smyth MP
Labour MP for Bristol South

The most interesting piece of this is the line that ‘renewables today are nine times cheaper than gas’. Nine times! This tells me that we are definitely being exploited by the fossil fuel companies.

Starmer Announces Some Great Policies – But Can We Trust Him?

September 28, 2022

I got this email from the Labour leader yesterday, along with the inevitable request for a donation. There are some great policies in there, such as a publicly owned energy company. The problem is that Starmer’s got plenty of previous on making promises he has no intention of keeping, and of watering down his proposals when he starts thinking he’s getting near power.

‘David James, if this year’s Conference has proved one thing, it is this: 

Labour will deliver a fairer, greener future for working people. 

Here’s how we’ll do it:

In my first year as Prime Minister, Britain will start its journey to becoming a clean energy superpower by setting up a new, publicly owned company: Great British Energy. 

Publicly owned British power. 

Creating hundreds of thousands of jobs, growing our economy and protecting our country from being held to ransom by dictators like Putin.

British power to the British people.

Clean hydrogen energy in South Yorkshire, in the East of England, across the river in the Wirral. Offshore wind in Scotland, Teesside, East and North Yorkshire. Solar power, growing rural communities, in the South East, South West and Midlands.

David James, to achieve this, Labour must win. 

Will you chip into the General Election fund today, for a fairer, greener future tomorrow?

I’ll donate

While the Tories lurch from crisis to crisis, Labour’s green prosperity plan will deliver an economy that works for everyone.

Labour will:  

  • Freeze energy bills now with a windfall tax on oil and gas producers 
  • Keep bills down long term by insulating 19 million homes 
  • Secure energy independence with GB Energy 
  • Create one million new jobs by investing in new green industries 
  • Safeguard nature and our children’s future with a Clean Air Act 

Britain deserves better than Liz Truss’ trickle-down fantasy.

Britain deserves a fairer, greener future. 

Labour is ready.

Thank you, 

Keir Starmer 
Leader of the Labour Party’ 

Fabio Pacucci on the Science of Space Elevators

December 11, 2021

This short video comes from the TedEd channel on YouTube, presumably connected to the TED talks in which leading intellectuals and academics explain their ideas. In this case, its about space elevators. These are long cables that would carry materials and passengers up to Earth orbit. The idea was first proposed by Russian space pioneer, Konstantin Tsiolkovsky, in 1895, after the deaf school teacher saw the tallest building in the world at the time. If one could be built, it would massively reduce the costs of transporting people and material to orbit. These would be taken aloft in special capsules called ‘Climbers’, which would have to be shielded against radiation to protect human passengers. At the moment, it costs SpaceX $7,600 per kilo. It’s estimated that space elevators, their immense power needs supplied either by solar energy or nuclear power, could reduce this by 95 per cent. The problem is that that at the moment there is no material strong enough to support such a building. It has been suggested that carbon monofilaments and nanotubes could provide the solution, but only tiny amounts of these have been manufactured at the moment. There is also the problem that the gravitational stresses and hence the thickness of the cable would vary with height. One solution to this problem would be to extend the cable to counterweight, either a satellite or captured asteroid in geostationary orbit 36,000 km above the Earth. The problem of keeping the tether rigid would be solved by using centrifugal force from the Earth’s spin. The station back on Terra would be best situated at the equator, and possibly a ship at sea. This would allow it mobility to avoid storms and terrible weather. It is immensely difficult to build such an elevator on Earth, but they could be built on the Moon and Mars using current technology and materials. But they’d be far more of an advantage built here on Earth. Another problem is that if the cable was cut, the effects as it fell to Earth would be catastrophic. Despite the difficulties of construction, there are companies in China and Japan planning to build them by 2050.

The idea of the space elevator has been around for some time. Arthur C. Clarke thought for a while that he had invented the idea in his book about the building of such a tower in his adopted home of Sri Lanka in his 1970s novel, The Fountains of Paradise. This lasted until he looked the idea up in the scientific literature, and found it went all the back to the Russians. It would truly be a giant leap in space exploitation and colonisation if we could build a space elevator, but I think building one by 2050 is extremely optimistic. Way back in the 1990s or the early part of this century I remember an American firm announcing they were going to develop the idea. Unfortunately one of the problems at the time is that, according to the techniques being proposed, the station back on Earth would have to be anchored by an entire mountain range. So, not really possible and that was the end anyone heard of the idea.

It’s great that research into space elevators is continuing, but I think it will be a long time before they become reality, whether built by Americans, Chinese, Japanese or whoever.

‘I’: British Government Considering Solar Power Satellites

November 17, 2020

A bit more space technology news now. The weekend edition of the I, for Saturday 14th November 2020 carried a piece by Tom Bawden, ‘The final frontier for energy’ with the subtitle ‘Revealed: the UK is supporting a plan to create a giant solar power station in space’. The article ran

Millions of British homes could be powered by a giant solar power station 24,000 miles up in space within three decades, under proposals being considered by the government.

Under the plan, a system of five huge satellites – each more than a mile wide, covered in solar panels and weighing several thousand tons – would deliver laser beams of energy down to Earth.

These would provide up to 15 per cent of the country’s electricity supply by 2050, enough to power four million households – with the first space energy expected to be delivered by 2040. Each satellite would be made from tens of thousands of small modules, propelled into space through 200 separate rocket launches, and then assembled by robots.

The satellites would use thousands of mirrors to concentrate the sunlight on to the solar panels, which would be converted into high frequency radio waves. These would be beamed to a receiving antenna on the Earth, converted into electricity and delivered to our homes.

While the prospect of a solar space station beaming energy into our homes might seem outlandish, advocates are hopeful it can be done. The Government and the UK Space Agency are taking the technology extremely seriously, believing it could play a crucial role in helping the country to fulfil its promise of becoming carbon neutral – or net zero – by 2050, while keeping the lights on.

They have appointed the engineering consultancy Frazer-Nash to look into the technical and economic feasibility and it will report back next year.

“Solar space stations may sound like science fiction, but they could be a game-changing new source of energy for the UK and the rest of the world,” the science minister, Amanda Solloway, said.

“This pioneering study will help shine a light on the possibilities for a space-based solar power system which, if successful, could play an important role in reducing our emissions and meeting the UK’s ambitious climate-change targets,” she said.

Martin Soltau, of Frazer-Nash, who is leading the feasibility study, said: “This technology is really exciting and could be a real force for good. It has the potential to transform the energy market and make the net-zero target achievable – and from an engineering perspective it looks feasible.”

Previous analysis by other researchers on economic viability suggests space solar could be “competitive” with existing methods of electricity generation but that will need to be independently assessed, Mr Soltau said.

If the UK is to become net zero it needs to find a green source of energy that is totally dependable because the wind doesn’t always blow and the sun definitely doesn’t always shine.

This is where solar space comes in, with its panels sufficiently much closer to the sun that they are not blighted by clouds and darkness.

“This would provide a baseload of energy 24/7 and 365 days a year – and has a fuel supply for the next five billion years,” said Mr Soltau, referring to the predicted date of the sun’s eventual demise.

Until recently, this project really would have been a pipe dream – but two developments mean it is now a realistic prospect, Mr Soltau says.

The first is the new generation of reusable rockets, such as the Falcon 9 launcher from Elon Musk’s SpaceX, which mean satellites can be sent into space far more cheaply.

The cost of launching objects into low Earth orbit has gone from about $20,000 (£15,000) a kilogram in the early 2000s to less $3,000 now – and looks to fall below $1,000 in the coming years, he says.

At the same time, solar panels are much cheaper and more than three times as efficient as they were in the 1990s, meaning far fewer need to be sent into orbit to produce the same amount of energy.

Mr Soltau is hopeful, although by no means certain, that his study will find the technology to be feasible in economic and engineering terms – with the technology looking like it’s on track.

The five satellite solar power station system envisaged by the Government will probably cost more than £10bn – and potentially quite a lot more – more than the Hinkley Point C nuclear power station, which would produce roughly similar amounts of electricity, is expected to cost about £30bn, including decommissioning, Mr Soltau points out.

When all is said and done, there’s no getting away from the fact that building a satellite of that size and complexity in orbit is a mindboggling task. But it could well be feasible.

The article was accompanied by this diagram.

The captions read

  1. Solar reflectors: Orientation of satellite with respect to the Sun controlled to constantly reflect sunlight onto the solar power array below.
  2. Solar panels and transmitters: Approximately 60,000 layers of solar panels that collect the sunlight from the reflectors, and convert this to transmit high frequency radio waves.
  3. Power transmission: High frequency radio wave transmission from satellite to receiver on ground.
  4. Ground station: approximately 5k in diameter rectenna (a special type of receiving antenna that is used for converting electromagnetic energy into direct current (DC) electricity), generating 2 gigawatts of power enough for 2 million people at peak demand.

The solar reflectors are the objects which look rather like DVDs/CDs. The box at the top of the diagram gives the heights of a few other objects for comparison.

The ISS – 110m

The London Shard – 310m

The Burj Khalifa – 830m

The Cassiopeia solar satellite 1,700m.

The use of solar power satellites as a source of cheap, green energy was proposed decades ago, way back when I was at school in the 1970s. I first read about it in the Usborne Book of the Future. I don’t doubt that everything in the article is correct, and that the construction of such satellites would be comparable in price, or even possibly cheaper, than conventional terrestrial engineering projects. I went to a symposium on the popular commercialisation space at the headquarters of the British Interplanetary Society way back at the beginning of this century. One of the speakers was an engineer, who stated that the construction of space stations, including space hotels, was actually comparable in cost to building a tower block here on Earth. There was just a difference in attitude. Although comparable in cost, such space stations were viewed as prohibitively expensive compared to similar terrestrial structures.

Apart from the expense involved, the other problem solar power satellites have is the method of transmission. All the previous systems I’ve seen beamed the power back to Earth as microwaves, which means that there is a possible danger from cancer. The use of laser beams might be a way round that, but I still wonder what the health and environmental impact would be, especially if the receiving station is around 5 km long.

I also wonder if the project would ever be able to overcome the opposition of vested interests, such as the nuclear and fossil fuel industries. One of the reasons the Trump government has been so keen to repeal environmental legislation and put in place measures to prevent the Environmental Protection Agency from doing its job, is because the Republican party receives very generous funding from the oil industry, and particularly the Koch brothers. And there are plenty of Tory MPs who also possess links to big oil.

At the moment this looks like a piece of industry PR material. It’s an interesting idea, and I’ve no doubt that it’s factually correct, but given the resistance of the British establishment to new ideas, and especially those which might involve government expenditure, I have grave doubts about whether it will actually ever become a reality. Fossil fuels might be destroying the planet, but there are enough people on the right who don’t believe that’s happening and who get a very tidy profit from it, that I can see the oil industry being promoted against such projects for decades to come.

‘I’ Review of Art Exhibition on Ecological Crisis and Some Solutions

January 8, 2020

Also of interest in yesterday’s I was a review by Sarah Kent of the exhibition, Eco-Visionaries, at the Royal Society in London. This was about the current ecological crisis, and showcased some possible solutions to the problem, some of them developed by architects. This included a moving desert city, the Green Machine, which also planted a watered crops as it moved. The article ran

Melancholy humming welcomes you to the exhibition, with a globe suspended in the cloudy waters of a polluted fish tank. This simple installation by the artist duo HeHe neatly pinpoints our predicament: our planet is suffocating.

“The absence of a future has already begun,” declare Ana Vaz and Tristan Bera in a film, Reclaimed (2015). We know this already – according to the UN, we need to cut carbon emissions to zero by 2050 if we are to prevent the collapse of the Earth’s ecosystem. So what are we waiting for?

Vaz and Bera highlight the problem. The situation requires a wholesale change in attitude: minor tinkering can’t solve it. We need “reciprocity with nature rather than domination… We are nature.” We are mesmerised by events such as the Arctic on fire, Greenland’s ice-cap melting and Venice drowning. But the scale of the problem is so enormous that we can only watch, “fascinated by the acceleration” of the crisis.

The collective Rimini Protokoli encourages us to confront our imminent extinction. On film we see a tank full of languidly floating jellyfish. They flourish in the warming seas and, with diminishing fish stocks, there’s less competition for the plankton they feed on, so their numbers are increasing dramatically. Humans are similarly multiplying – by 2050, according to the UN, there will be 9.7 billion of us – but unlike jellyfish, we require too much energy to adapt to climate change so, like the dinosaurs, our days are numbered. At the end of the presentation they invite us to go with the words: “Your time is up; you will have to leave.”

The Royal Academy is to be congratulated for hosting an exhibition that tackles this urgent issue, but the show exemplifies the problem. The warnings are persuasive, but the solutions envisaged are pitifully inadequate, mainly by architects who don’t address the catastrophe but instead offer us post-apocalyptic follies. The Green Machine (2014) is Studio Malka’s answer to desertification. Resembling a giant oil rig, this monstrosity trundles across the Sahara on caterpillar treads that plough the ground then sow and water the seeds to produce 20 million tons of food per year. Solar towers, wind turbines and water-capturing balloons create a “self-sufficient urban oasis” for those inside. What percentage of the 9.7 billion will they accommodate, I wonder?

Studio Malka’s Green Machine mobile desert city.

It’s a grim subject, and clearly the ecological crisis requires drastic action across the entire globe and very soon. But I am fascinated by the Green Machine. It reminds me of the giant moving cities that cross the devastated future Earth in the SF film Mortal  Engines. As for how many people such a machine could house, the answer is: very few. Douglas Murray’s book Last Futures: Nature, Technology and the End of Architecture predicts that if we carry on as we are, we will end up with a future in which the rich will inhabit closed, protected environments like the various biodomes that were created in the 1990s, while the rest of humanity will be left to fend for itself in the decaying world outside.

It’s a bleak, dystopian prediction, but one I fear will come true if we carry on electing leaders like Trump and Johnson.

Video of British Scientist Eric Laithwaite Explaining Principle of Magnetic Levitation (Maglev)

November 29, 2019

This is a fascinating film from Imperial College London. Shot in 1975, it shows great British scientist/engineer Eric Laithwaite explaining how a maglev train would work. He begins with first principles, simply showing how magnets act upon each other with bar magnets. Magnets with the same poles facing each other repel, and he demonstrates how this can be used to suspend one magnet above another. This can be done with ring magnets, but usually something has to hold them in place, like the solid glass tube in this video. But ordinary magnets don’t generated enough lift to raise heavy objects off the ground. He then moves on to electromagnets and how these can also be made to move aluminium objects along them when using AC current. The electromagnets can be flattened out to produce a kind of river – the ‘Magnetic River’ of the film’s title – along which an aluminium sheet can be propelled at great speed. He then shows how the same principle could be used to drive a train by placing a model on the maglev track.

Laithwaite was working on making maglev trains a reality when the project was cancelled due to the budget cuts of the late 70s. The idea has since been taken up by German and other, foreign engineers. It has been seen by visionary scientists and SF writers like Arthur C. Clarke as the solution to current transport problems through the great speed that these trains could in theory attain without friction from wheels touching the tracks. They would also be clean and green through being powered by electricity, preferably solar power, rather than the burning of coal or other hydrocarbons. See the discussion about them in Clarke’s Profiles of the Future.

Laithwaite is one of the great scientists most people have never heard of. In the 1990s he got caught up in developing anti-gravity based on his experiments with gyroscopes. His claim that he had discovered a new principle of anti-gravity propulsion was not accepted by the scientific community. I’ve got the impression that the furor that aroused has caused his earlier, solid work to be unfairly overlooked.

I realise the video’s long at just over 18 minutes, but it’s worth persevering with if you’re interested in the subject. Before computer graphics came in, this is pretty much what science broadcasting was like when I was a schoolboy. It was simply the scientist, engineer or presenter standing in front of the camera talking with the machine or other object in front of them, and using simple diagrams or illustrations. And I’m really impressed with the way Laithwaite is able to explain a sophisticated piece of engineering in ordinary, non-technical language. As one of the commenters says on the YouTube page for this, he would have been a great science teacher.

He isn’t quite on his own here. Helping him with the equipment is his mysterious assistant, Barry, who helps set the apparatus up and loads the sheets of aluminium and then the model train on the maglev tracks, but who never speaks.

It’s a very basic presentation compared to some of the films on today’s popular science television, and it’s not clear if it was intended for broadcast. But it was experts like Dr. Laithwaite who brought science to ordinary people and inspired a new generation witih its wonder when I was young.

Today the government is concerned about the lack of young people choosing to study STEM subjects. Perhaps if broadcasters were able to find a few more experts with ability to explain science with the simplicity of some of those, who graced our TVs then, people able to convey real enthusiasm for the subject, and weren’t afraid of putting more popular science programmes on TV, there would be more school and university students taking up these subjects.

 

 

AJ+ Video on the Bedouin Village the Israelis Wish to Demolish

November 24, 2018

This is a video that the Blairites, the Israel lobby, the Tories and the lamestream media really don’t want you to see. It’s the kind of video that would have Marlon Solomon, Maggie Cousins and the entire Board of Deputies of British Jews screaming ‘anti-Semitism!’ Not because it is – it isn’t – but simply because it shows the reality of what’s happening in Israel to the indigenous people. They’re having their homes demolished.

The video’s just less than five minutes long, and features host Dena Takruri walking through the Bedouin village of al-Zarnoug in the Negev desert, talking to one of its people, Basma Abo Qwedir. The village has existed since before Israel was founded in 1948, but the Israeli authorities don’t consider that it legitimately exists, and so have attempted to demolish it and forcibly relocate its people many times. And although its people are considered Israeli citizens, Abo Qwedir makes it very clear that she doesn’t believe this is remotely true. If she’s an Israeli, she says, then she’s a second- or third class one. The country doesn’t treat her as other citizens, such as Jews, for example.

The video states that al-Zarnoug is one of 35 unrecognized Arab villages in the desert with a total population of 70,000 people. They’ve been under threat of eviction since the Nakba of Palestine’s destruction through the foundation of Israel in 1948. In 2013 a bill was proposed for the villages’ demolition and the removal of its people to government-built townships. In some cases, the villages would be replaced by Jewish settlements. The Israeli authorities said they would shelve the plan after widespread protests, but the home demolitions have continued, including in al-Zarnoug.

As shown, it appears to be a village of grim, breeze-block and concrete housing. If the residents need to build new buildings, they have to be hidden behind corrugated iron sheeting, because if they go to the authorities for a building permit, it won’t be issued. The roads and thoroughfares are simply the bare soil. And before AJ+ visited the village, the Israelis demolished houses in the nearby village of El Araqid for the 90th time. Abo Qwedir explains that as the village doesn’t officially exist, it means that they don’t have electricity, infracture, playgrounds, sewage and roads as they should. She shows Takruri how the villagers get electricity from solar panels on their houses, which they can move to follow the sun. But in winter and rainy days when there is no sun, they have to rely on batteries.

Takruri states that Israel regards the development of the Negev desert as one of its most important goals, and the ministry of foreign affairs says that the country seeks to integrate villagers into its development plans. But residents like Ab Qwedir read between the lines that the government wishes to replacement them with Jews, because Arabs, Palestinians, ‘are not welcome here’.

The video concludes with Abo Qwedir saying that simply staying there is a form of resistance against the Israeli state. Everyone does it, she says. ‘Sometimes it’s against the wind, other times it’s against the state.’

The demolition of Arab homes has been a major issue for decades now, and many Israelis support the Arabs in the determination to stay in their homes. Jews, including rabbis, have campaigned against the house demolitions. From what I’ve read, the Israeli colonization of the Negev presents the Israeli state with a problem. As it stands at the moment, the desert’s very largely Arab in population, so that some Israelis have said that they feel the territory is ‘lost’. For Israel to settle the region with Jews, it will have to withdraw or abandon some Jewish settlements elsewhere, such as the Occupied Territories. Which will enrage the settlers there, who believe that as part of Eretz Israel, the West Bank should be firmly part of Israel and its indigenous people cleansed.

And this is probably part of the explanation why Israel is so keen to tell western Diaspora Jews that they’re not safe in Europe and America, and exploit every terrorist outrage, like the Pittsburgh shooting two weeks ago, to spread fear and encourage Jewish Americans and Europeans to move to Israel for their own safety. In Britain this led to the Campaign Against Anti-Semitism making the absurd and odious claim that Jews were facing the biggest rise in anti-Semitism since the 1930s. Hardly. This statement was so obviously wrong, that even one of the Jewish papers or organisations had to step in to show that it was utterly false.

It’s for sticking up for the people of Palestine against the destruction of their homes and their treatment as second-class citizens, that decent people like Jackie Walker, Tony Greenstein, Martin Odoni, Ken Livingstone and Mike, as well as Jeremy Corbyn himself, have been vilified as anti-Semites and worse by the Blairites, the Israel lobby and a corrupt, Tory media.

It’s because they’re afraid of a genuinely socialist Labour party getting into power, which really does support racial equality and dignity. As against the Blairites, the Neocons, and the Tories, who stand for imperialism, colonialism and war without end to promote Israel, western and Saudi oil interests, and the seizure of other nations’ state enterprises and oil reserves, for the benefit of the multinationals.

American Scientists Plan March against Trump

January 28, 2017

After the massive numbers of people involved in the women’s marches against Trump held around the world last weekend, American scientists are also planning to organise their own demonstration against the Orange Caudillo in protest at his disastrous environmental and health policies.

In this video, TYT Nation’s Jeff Waldorf discusses a report in Forbes’ discussing the formation of the new group of scientists planning this march. The group has it’s own internet page, and in five days its members grew from 200 to 200,000 +. The group says it will include non-scientists as well as scientists, and is intended to advocate the greater involvement of science in government. It’s purpose is to defend climate science, evolution, and alternative energy. Waldorf states that he too believes strongly that science should be more involved in government. He also quibbles with the phrasing in the Forbes’ article, taking issue with the magazine’s description of the scientists as ‘believing’ in the environmental damage caused by the fossil fuel industries. Waldorf argues that scientists’ in these areas don’t believe, because they have proof that oil pipelines, such as DAPL, can rupture, creating massive oil spills and environmental destruction.

Waldorf also argues that, although he understands why people in America’s coal country wish to retain the industry for as long as possible for the sake of their jobs, renewables are now becoming cheaper than oil for the first time. It’s time to move from the horse and buggy to the automobile, is the metaphor he uses. He also notes that 75 per cent of Trumps’ own supporters are also in favour of solar and wind power, and natural gas. Waldorf himself is not in favour of natural gas, as it’s still a fossil fuel, with the environmental problems that poses. At the moment, the movement is still in the planning stage, but hopes to issue a mission statement soon. In the meantime, they state that a government that sacrifices science to ideology is a threat not just to America, but also the world.

I wish the scientists the best of luck in their campaigns against Trump’s attack on climate change and green energy. I think, however, Waldorf has a rather too optimistic view of science. There’s quite a debate in the philosophy of science over what constitutes ‘proof’. In one view, articulated by the great philosopher of science, Karl Popper, science advances through falsification. You can’t prove a particular theory. What you do instead is show that other explanations are false. In many areas of science, the observable effects of experiments, may be tiny and ambiguous. This is why scientists have developed very sophisticated statistical methods for sorting through their observations in search of factual evidence that will support or disprove their theories. Thus, at the risk of nit-picking, it might be fairer to say that climate change and environmental damage by the fossil fuel industry is far better supported by the available evidence, than the minority view that no such change or damage is occurring.

I also think you have to be careful about relying too much on science to solve social problems. The British philosopher, Mary Midgeley, in one of her books pointed out that in some areas, what is needed is a social and industrial solution to a particularly issue, rather than scientific innovation. For example, it could be argued that in the struggle against world hunger, what is needed is not new, genetically engineered crops which produce vast yields, but better transportation methods and infrastructure to supply people with the food that has already been grown.

Despite these very minor quibbles, it is true that orthodox, respectable science in the above areas has been under attack for a long time to serve powerful interests in the fossil fuel industries. Trump this week imposed gagging orders preventing scientists and government workers in the Environmental Protection Agency from revealing their findings. Climate change is happening, and is a real danger to America and the globe. But this awareness frightens the Koch brothers and their wealth in the petrochemical industry. So they, and millionaires like them, are spending vast sums to keep the facts from ordinary peeps. America’s scientists are right to challenge this. Let’s hope their march in support of proper science goes ahead and is well-attended.

Trump Imposes Gag Order on Government Environmental Scientists

January 28, 2017

The Republican party since the 1980s, if not before, has a bitter hatred of environmentalism and loathes just about any and all laws, movements or protests to protect Earth’s precious natural resources, and the creatures with whom we share our beautiful world. Now Trump’s taken it to its latest development.

In this video, The Young Turks’ Cenk Uygur and Ana Kasparian discuss Trump’s imposition of a legal ban gagging members of the Environmental Protection Agency from releasing details of their work to the general public. Trump has also frozen official funding, so that the Agency may only publish its results and findings if these meet the official, ideological approval of his administration.

Uygur and Kasparian point out that this is intended to keep people ignorant, powerless and deprived of decent science education before Trump’s government. They also point out that this action by the Orange Dictator shows without question that the Republicans are anti-science. It doesn’t matter whether individual Republican voters support Trump’s policy, or they merely have to go along with it because they agree with his others reforms. The Republicans are anti-science, and they should now own it.

They also make the point that in any jobs that may actually be brought back to America through these bans, Americans will be fighting for scraps. The jobs in the petrochemical sectors drilling for oil, which the attacks on the EPA are designed to protect, will not be such to give Americans the standard of living they want. It would make far greater sense for the government to begin investigating in renewables – a whole new industry. At the moment, even the Chinese are beating America in investment and research into renewable energy, because, says Uygur, ‘the Chinese are smart’. But there’s no reasons why America shouldn’t be no. 1 in renewable energy. They’ve got enough sun in Arizona and wind in Chicago, the notorious ‘windy city’.

The Young Turks here are right. This is all about protecting the Republican party’s corporate backers in the petrochemical industry, like the Koch brothers. These two have financed a slew of fake astroturf ‘Green’ organisations and campaigned against genuine climate science produced by independent university laboratories. Koch money has been poured into Unis and state coffers instead to produce very politicised labs that have been set up to deny that climate change is occurring, and that drilling for oil is having a harmful effect on the local landscape of the US. This is despite plenty of evidence to the contrary, such as vast stretches of Louisiana wetland now made little more than one vast oil bog. Or the fact that there were over 300 spills from the oil pipelines crisscrossing America last year. The Kochs and their dollars try to keep facts like these well-hidden from the voters and the folks that have to live with the results of their environmental pillage.

And whatever the Republicans do, the Tories are nearly always bound to follow. The Republicans have heavily embraced fracking, and so have the Tories and their Lib Dem enablers. So you can bet that at this moment, Theresa May, members of her cabinet, or perhaps the members of some Tory think tank somewhere, is looking at these gagging laws, and wondering how something similar can be introduced over here.
