I agree with most of what you said. I only take issue with the lead acid acceptability in EVs. Sadly, they are probably the worst battery to use. They just happen to be everywhere, and cheap.

There are some great non-lithium batteries out there that could be used in EVs. I especially like the nickle-iron (Edison "Ironclads") that powered just about every EV until the 30's. They last forever, and in slower EVs work very well. They can't pump out the amps as LA or fancier chemistries, but then they wouldn't have to. They would be perfect for shitty NEVs, and would last decades. In fact, IIRC, NiMH are a variation on NiFe.

I would love to see those Stirling engines out of Dean's wet dreams and in my house, though. I can see that as the perfect way to marry a solar thermal and a solar electric system that would cost a tenth as much as photovoltaic.

Good to see you posting again!

I agree that there are better non lithium out there, and lead acid do kinda suck. but they are out there, and if you watch what this guy is doing, you can take all the lead acid batteries that are now on their way to be recycled (that's one thing that lead acid does well, there's more recycling than any other batteries) but he takes the dead ones that are supposedly only good for recycling, and revives them, and then driver around Vancouver with them!

personally i like Evyonix batteries http://www.evionyx.com which are being used by some people converting cars to BEV now--- and these AXION carbon lead batteries show great promise.

But my favorite is not in the battery, rather in the charging... this KAIST project in Korea is brilliant! They use inductive charging, lay strips into the roads, and then as long as they are on 20% of the roads, you charge while driving! You can use about 1/5 of the regular amount of BEV batteries and never run out of juice! OK that might be a bit ( ... )

I'd be interested to learn more about that battery reviving process. Then again, I have a special hatred for liquid electrolyte batteries in vehicles. It's just too dangerous.

I say this as someone involved once in a hit-and-run motorcycle accident who had a bike pinning his leg to the pavement for way too long. Had that bike been both all-electric and using flooded batts, I would have lost my jeans, at least.

Here's some more info about it, and some more info, and some more... he sells complete plans for $99. I imagine that anyone who does this can then start a recycling company and end up with more batteries to revive than could drive an army of BEVs.... The guys name is Rob Matthies email me(littlecatalyst at gmail), and i can send you his phone numbers so you can ask questions before buying the $99 kit...

just so you know, when i had 2 wheel EV copmpany (back in 1999, kinda like vespas but coudl do 70kmH) all our batteries were under where you'd put your feet, if tere was an accident it would be too low....
