I'm not sure I'd actually put money on it.. But I did buy an electric scooter from them about 8 years ago and they are near the forefront of electric vehicle development. At least a close as a smaller company can be. They used to have an electric motorbike that isn't on the site any more. Maybe high gas prices will give these guys a bit of a kick. Took a quick squiz at their chart, seems they've rebounded pretty heavily in the last month. Not really going to research why.
Personally I'd stick to oilers or alternative energy stocks.
