Guest Post by Geoff Russell. Geoff recently released the popular book “Greenjacked! The derailing of environmental action on climate change“.
Many nuclear supporters tend to shy away from overt criticism of renewable technologies because they are confident that in any objective analysis, unencumbered by radio-phobia, nuclear will dominate any effective response to climate change; should the world choose to give a damn. After all there is no shortage of very careful objective treatments that support such a view. But every so often the solar industry, in particular, shoots itself in the foot with a spectacular demonstration of just how bad this technology is and it behooves us all to call a spade a spade and a lemon a lemon.
I’m talking about the Solar Impulse circumnavigation project.
The Solar Impulse is a solar powered aircraft consisting of more than 17,000 solar cells and 633 kilograms of lithium batteries packed into a plane with a wingspan longer than a Boeing 747. Not to mention a cast including 80 engineers, 100 advisers, a 12 year construction time, sponsorship from 80 companies including Google, a real-time website, T-shirts and of course, the obligatory baseball caps. But my personal favourite, because the project hails from Switzerland, has to be the Victorinox commemorative pen knives which will get confiscated should you try to take them on-board a real plane.
How will Solar Impulse compare with Around the World in 80 days? That was a pretty good yarn, written by Jules Verne in 1873. But Verne’s story is fictional. Phileas Fogg didn’t exist and never really attempted to circumnavigate the world in 80 days to win a rather large bet. While it never happened, it did, apparently, create intense publicity at the time because people thought it was really happening. Which neatly mirrors, or perhaps I should say “heliostats”, the renewable energy “revolution”.
Some 140 years after Verne’s book, the Solar Impulse is definitely non-fiction. You can watch it in real time and buy stuff. The initial leg of the journey was on March the 9th and, as I write (May 31), they’re about to take off across the Pacific. Here’s a table of the legs completed so far and the other 6 listed on the website:
By my reckoning they’ll be about 5000 km short of a circumference, but we’ll let that slide. My real interest is how they managed to sell this as an achievement. In 2008 Mark Beaumont cycled around the planet in 195 days pedalling 29,000 kilometers … presumably with some shipping. That’s seriously tough. But it’s no feat of technology and doesn’t demonstrate a superior mode of locomotion or foreshadow a global shift to pedal power.
Does the Solar Impulse demonstrate a superior mode of transport? Does it herald a future of solar planes? Don’t be daft. It’s slow, expensive, risky, fragile, dangerous and the total payload delivered by all those panels and batteries and dollars is just a single person; the pilot. If there were ever a Solar Olympics, the motto would be something like slower, lower, and weaker.
