BBC World Service Programme Next Tuesday on Scientists Generating Electricity from Leaves

May 13, 2020

This sounds completely bonkers, like the academy discussing ways to generate sunlight from cucumbers in Swift’s great satire, Gulliver’s Travels, but apparently is real science. According to the Radio Times again, next Tuesday, 19th May 2020, the BBC World Service programme, People Fixing the World, is about how scientists have found a way to generate electricity from leaves. The blurb about the programme by Tom Goulding on page 120 of the Radio Times runs

Money might not grow on trees, but scientists in Italy might have discovered the next best thing: leaves that generate electricity when they touch one another on a windy day. This process, enough to power 150 LED lights, is one of several remarkably simple ways of producing energy that scientists are just beginning to understand. In this optimistic documentary, reporter Daniel Gordon investigates some age-old ideas that could finally become viable renewable energy sources with new technology, such as the interaction between fresh and salt water at estuaries and a 5 km well being dug to extract untapped heat in Iceland.

The programme is on at 3.05 in the afternoon.

This sound really awesome, though it reminds me a little of the ‘treeborg’, a cyborg tree aboard a spaceship in a Matt Smith Dr. Who story, and also somewhat of the Matrix films, in which the robots have risen up and enslaved humanity. Unable to use sunlight after humanity wrecked the planet’s whether and created permanently overcast skies, the machines turned instead to growing us all in bottles and using the electricity generated from our bodies. Fortunately, I don’t think that’s a viable option. After the movie came out, people naturally wondered whether that could actually work. And the answer is, that it doesn’t. The amount of electricity generated by the human body is way too small. Nevertheless, reading this in the Radio Times makes you wonder if someone couldn’t harness it to provide useful power, nonetheless. Should the producers of this programme be giving them ideas?

Going on to geothermal power, I can remember in the 1970s watching items about it in Iceland on the popular science programmes’ Tomorrow’s World on the Beeb and Don’t Ask Me on ITV. That was the programme that gave the viewing public the great science broadcasters Magnus Pike and David ‘Botanic Man’ Bellamy.

I haven’t heard of electricity being generated by the interaction between fresh and salt water before, but I was amazed at how long ago tidal power has been around as a possible power source. Turbine wheels were put in the Thames estuary in the 16th century to provide power for mills. George Bernard Shaw also mentions tidal power in his book, The Intelligent Woman’s Guide to Socialism, Capitalism, Sovietism and Fascism. As an example of the type of wrangling that goes on in parliamentary democracy, he asks the reader to imagine the type of fierce debate that would occur if someone suggested putting up a tidal barrage in one of Britain’s great rivers. There would be a fiery contingent from Wales arguing that it should be on the Severn, and an equally fierce body of proud Scots declaring it should be on one of their rivers. I don’t think he need have worried. There have been debates about building a barrage on the Severn since I was at secondary school, and it’s no nearer being built because of concerns over its ecological effects.

But this programme sound amazing. I thinks there’s a simple science experiment for children, in which electrodes are stuck into a lemon or potato, and connected together to turn on an electric lightbulb. Will we be doing something similar in our gardens in a few years’ time, just as people are now putting solar panels on their rooves?

 

BBC 4 Looks Back at Tomorrow’s World

November 22, 2018

Tonight, Thursday 22nd November 2018 at 9.00 pm BBC 4 are looking back at the 1980’s BBC science show, Tomorrow’s World. The programme’s entitled Tomorrow’s World Live: for One Night Only, and the blurb for it in the Radio Times runs

Dr. Hannah Fry joins former presenters Maggie Philbin and Howard Stableford for a one-off live revival of the much-loved science and technology series, which ran from 1965 to 2003. They will be looking at the programme’s archive, discovering the latest in British inventions, testing new technologies in the studio and looking forward to the innovations that will shape our future. (p. 97).

The other short piece about the show by Mark Braxton, on page 95, says

To think the BBC’s flagship science show might have been called “To Be Announced”. Creator Glyn Jones only came up with the title the night before RT went to press back in July 1965. But then there was always something excitingly seat-of-the-pants about Tomorrow’s World.

The influential series ran for 38 years, fronted by a conveyor belt of hosts from the old-school (blazer-sporting Spitfire pilot Raymond Baxter) and the smooth (Michael Rodd) to the long-running (Judith Hann, for 20 years).

It soon became known for things going awry on live TV – Baxter later gamely spoofed both himself and the programme on The Goodies (“This entire studio is held together with string.” Crash!). But the fact is that this was the first chance the public had to see new tech in action: the home computer, artificial grass, the digital watch, personal stereos and so on.

So in this one-off special, ex-Tomorrow people Maggie Philbin and Howard Stableford take a fond look back and a peek into the future. though I won’t consider the project complete without Johnny Dankworth’s jaunty jazz theme and the show spelt out in cake, nails and fried egg.

The Radio Times also has an article on the show by James Burke, another of its presenters, on pages 18 to 21, which includes a list of the predictions the show got right and got wrong. I remember Burke presenting the Beeb’s coverage of the US space missions in the 1970s, like the Link-Up when US and Russian astronauts and cosmonauts docked in space for the first time, and then returned to Earth in each others’ craft, if I recall correctly. I was fascinated by it, despite being only eight at the time. Burke also presented the Beeb’s science blockbuster series Connections and The Day the Universe Changed.

And here’s the show’s titles and theme tune from the Revoxy Channel on YouTube.
