The weird and wonderful World Solar Challenge 2019: No, this is not a Back to the Future-style nuclear-powered DeLorean, but a contestant in this year’s World Solar Challenge, in which vehicles powered by the sun compete in a 3000 km race in Australia. The event has been running biennially since 1987, and sees teams from around the world bring their (often highly futuristic) creations to race against one another. This image shows the IVE Engineering team’s vehicle, named Sophie 6s, which came all the way from Hong Kong.
