The Stella running system (lights and such not propulsion) uses 50 watts. The Stella propulsion system consumes 35wh per km. Pretty good. This could possibly be done with 4 high efficiency hub motors. Lawrence Rhodes -- next part -- An HTML attachment was scrubbed...

But in daily use on real world roads, where it might be cloudy or sunny, where trees and structures often shade the streets? E, I don't think so. And as I showed before, based on the energy consumption and PV output specifications provided for this vehicle, the claim is just not credible

This may be a relevant adventure story, now 5 years old, about lessons from a Canadian solar car, which as far as I know still holds the distance record. Google XOF1, or look at XOF1.com and you’ll find some references. The car named XOF1 travelled more than 35,000 km in the US and Canada, using

While it sure sounds like a fun project...by far the easiest way to have a solar-powered car is to leave the panels at home, on the roof of the garage or home. Unless I'm sorely mistraken, a significant fraction of the EVs owned by people reading these words are already solar-powered. Not to

Indeed - numbers don't lie. A decent family car has no more roof surface than max 15 x 6ft or about 90 sqft. At current (low cost) solar panel efficiency, the max you could get out of that is around 12W per sqft (at perfect angle of irradiation, so in practice, a lot less!) which means you might
