The ELF Gains Traction

Wed.  04/29 8a: ELF stands for Electric, Light and Fun, And this particular Elf is an invention that launched with a kickstarter in 2013. As Living on Earth’s Helen Palmer reported, it's a human and solar powered covered tricycle that aims to create a commuting revolution, and might just help combat climate change. Now two years on from the Elf’s kickstarter campaign, its designer and developer, Rob Cotter, tells Living on Earth's Helen Palmer how successful the invention has proved, and how much of a contribution it’s making to cutting CO2 emissions.
