Finally something solar-powered that’s got some speed. The Czeerz MK1 is a Dutch-made speedboat that relies only on solar energy, which makes it the first solar speedboat. The 10 meters-long boat reaches the speed of 30 knots which isn’t bad at all for this kind of vehicles. It has a light, carbon fiber shell covered with 14 square meters of solar panels that power an 80 kilowatt engine. Only thing this thing lacks is space, u can only get 2 people in it and they wouldn’t be very comfortable. But after all it’s built for speed not comfort. Source
