Ah, but then we get into beefier side panels, airbags, and other crashworthy items the market now requires. Not that it can't be done with modern lightweight materials and all, but these either raise the mass or the cost... Cal Frye > Lawrence Rhodes via EV > September

You are still thinking 3000 pound conversions. Cut the weight and cut the battery weight. Get good aerodynamics. I bet Clouds Dolphin would do great with a 1kw of solar. Imagine it at 1500 pounds with a small pack. Just do the math. It's all about the numbers. The lighter the vehicle the mo

Schlörwagen is the vehicle built in the 30's with a .16CD. The list gods didn't like the URL and put random characters in the URL. Replace Schlorwagen in the URL or search Wikipedia or the web. http://www.greencarreports.com/news/1099022_new-stella-solar-electric-car-produces-more-energy-tha

It hardly makes a difference how efficient the elements can be as the sun only makes just so much power on a given surface, it a given time of day and a given angle of persentation of the element. If your elements were 100% efficient and rotated 60 degrees away from direct you would only get 50% o

Unfortunately the only useful bit of information is missing: how much efficiency is expected in future with this technology? At this moment the efficiency of just over 12% is underwhelming, because mass produced cheap silicon PV easily reaches 15% and in labs there have been versions that go to th
