I just found this camper prototype that traveled down to the Southern tip of Spain to show off the possibilities of solar powered camping travel. Its made by engineers at Eindhoven University of Technology which according to “Fully Charged” is the team that “always” wins the solar challenge in Australia. They claim 1700 kg gross weight, 600 km range and three days of good sun to fully charge. It looks like they are following in Aptera’s footsteps. https://www.youtube.com/watch?v=4vHuldVlpFAhttps://www.youtube.com/watch?v=4vHuldVlpFA
Minor clarification if you don’t mind. Eindhoven has, when they entered, always won the “Cruiser Class” at the Bridgestone World Solar Challenge in Australia. The more competitive class is called the “Challenger” class and it has been won, most often, by yet another University in The Netherlands called Delft University of Technology. Clearly there’s something in the water in The Netherlands!
