Valence Technology: Green Stock with Potential to Bloom

Valence batteries are a different chemistry than laptop batteries, specifically for large format/mobile uses.
The upside is they will not catch fire and explode in an accident.
The downside is they have much less energy density than laptop batteries. So NO WAY would they ever be used in laptops.

I suppose they might help with global warming, inasmuch as
lithium batteries will be important in hybrid cars, which will
help with global warming.

Read up on this company, because it's management seems
pretty weak. It has a 15 year history of negative earnings,
but it also has a billionaire backer so it doesn't fail.
