More Questions ....
An interesting concept indeed.
However, there are many questions that must be asked.
Can we afford to tear up and rebuild roads to accommodate this technology? Probably not.
What is the source of this power? Coal? Oil? Nuclear? Not that much hydro-electic power around.
It's not really replacing oil or coal; is it?
The ideas need to be planned in a "cradle to grave" fashion.
Otherwise, we'll end up having another ethanol from corn situation .... far from the roaring success that had originally been envisioned.
There are solutions that will be found; probably, though not based on the single user vehicle concept, which by nature is flawed.
