To be honest, I think this vehicle is a bit extreme but I don't see any fundamental reason why it wouldn't work as advertised. The design looks simple enough (but a bit wild and maybe not very practical). The square meters add up to the advertised solar capacity and the narrative as to why this would be efficient seems plausible as well. Probably there are going to be a lot more practical vehicles that you can buy for 25K pretty soon and probably cheaper than that even. Some of them even might have some solar panels. Why not?
