This might give cars 4 times the range.

I still think that magnesium-sulfur batteries will be the ones that pan-out in the very long run for most applications excluding those applications where the power density is of such critical importance (such as in unmanned electric aircraft ) that it would be worth having a much more expensive battery for the greater power density. This is in spite of them hav ...[text shortened]... nk there should be a massive international effort to start to develop them as soon as possible.
Originally posted by sonhouseAs you are talking here about mass rather than volume; it is the 'specific energy' you want to know here although there is much confusion between energy density and the specific energy and the two are often erroneously stated as the same thing.

Originally posted by joe beyserEventually there will be solar paint jobs on cars and maybe 20% at that so you can charge your batteries by having your car parked in the sun all day. Wouldn't that be great! Zero energy requirement. It would be great for gypsies! Imagine a camper with all that square footage covered in solar paint, they go to a camp site, stay for a week gathering energy then off to the next site🙂
I hope they will see the light of day. They are getting more competitive with petroleum based fuel now.
Originally posted by sonhouseDon't forget that paint can be used on garages and houses. With these batteries for storage one could use it for home energy as well as plugging the car in overnight. I am up for it, but the energy companies will likely try and kill a technology they can't make money on that competes with the current system of things.

Originally posted by joe beyserYes but the lure to end our dependence on foreign oil would be great and the energy companies could very well end up controlling solar paint too like they do coal and oil and gas today. The solar paint idea is actually being developed so it is not a pipe dream. The question is not if it can be done but what efficiency will be achieved by this technology. 1% would not cut it. 20% and you have something.

Originally posted by sonhouseThere is simply no strong case for paint. You could cover the roof with standard solar cells and get the latest technology and highest efficiency available. Using paint would not significantly increase the surface area available.

Originally posted by twhiteheadWhere I work, and for millions of other folk, my car sits out in the sun all day, no help for it and yes it gets hot as hell inside and outside the car.

For campers, it makes sense to have a solar array that can unfold at the camp site and also be directed to face the sun.
For ...[text shortened]... t of the parking is in multistory covered parking, so solar panels on the car would be useless.
Originally posted by sonhouseSo put up covered parking for it with solar cells on the roof. Not only will you keep your car cooler, but the power you save will pay for the covered parking.
