Nlkko,

I'd have to say I am far more pessimistic than you are when it comes to battery and re-charging tech. Your cell phone tech example is not particularly convincing because we are only dealing with jumps from 5V @ 0.5A (ie. 2.5W) to 5 - 20V @ 5A (ie. max of 100W), so those are all pretty small numbers, and it is easy to scale up when the numbers are small. But when you are scaling up from 110V - 220V to 480V - 1000V+ at 100A+, the requirements and difficulties become far greater, meaning progress becomes much slower.

I'd be very happy to be proven wrong, but until I see them out in the consumers' hands, I won't believe in their feasibility.
