電動汽車的未來不怎麽樣

Good thinking on your part.

Here are some comments I would like to make:

1. 快速充電隻有數學上的意義。
60 mph --> 3 hours (200 mile range?) --> 100 kw (?) * 3 hours --> 600 kw charge rate (use 0.5 half hour)

600 kw /200 (home voltage) --> 3000 amp --> may have to use copper wire with a diameter of, say, 20 cm (not a scientific number)

2. 換電池 --> Better Place Inc. is working on that. Then again, how many stations do we need? How those stations have to be constructed (imagine those are huge energy sinkers)? Don't we have to reconstruct all the electrical power grid to handle the surge?

3. 解決了汽車動力問題，也就解決了中國能源50%的問題???
Not so fast.
