I assume that you guys have seen the Tesla Roadster (http://teslamotors.com http://teslamotors.com).
What I'm hearing from them is that the critical feature that is holding electric cars back is the power system. This field is pretty experimental but someone who could come up with the magic battery that charges in 5 minutes would probably have a valuable system on their hands.
Another angle would be to have cars that run on batteries that can be swapped out at gas stations as needed. There are a bunch of issues that need to be considered for this approach but it's still a neat idea.
- Electro 19y agoYeah I've seen the Tesla Roadster, and all electric cars need to be manufactured like that. I have a Li-Ion drill, it takes 30 minutes to get a full charge yet it takes me over 4 hours to run it down with constant use, so I don't get how some electric cars can barely get you around town and take 8 hours to charge on a night. I'd accept 2 hour charge time for in city driving, but most of my driving with work isn't in a city, and thus electrics are useless until they're as fast to charge as a petrol is to fill.
- kschrader 19y agoMaybe because moving an electric car takes slightly more energy than turning a drill bit. It's not really the same class of problem.
