I agree. What else is our government good for, if not to impress us
with all of it's wizardly expertise and can-do mindset.

The all electric car is technically doable, although having even a
small onboard ICE for the minimal cruising needs of sustaining 60+ mph
might represent a good compromise, especially if it's contributing
zero NOx and minimal CO2 at a hybrid usage of 200 empg per fossil fuel
usage.

Double ditto right back at you, as I've been there and done that. Of
course double-ditto-duh once again, as it's hybrid city or local
commute empg, and having replaced our mostly N2 atmosphere with that
robust fluid of h2o2, so that we obtain the most clean energy and best
amount of bang per gallon of whatever fossil or biofuel, is actually
accomplished within existing physics and doable technology.

I believe the mass ratio is something like roughly 7:1 up to :1 for
h2o2/c12h26 (hydrogen peroxide / kerosene or RP-1), a little better on
certain heavier fuel oils such as diesel and perhaps nearly as
good enough with plain old gasoline, and a bit worse off with certain
biofuels, though all dual fuel injected and 100% computer controlled
(of course), so that your little zero NOx engine for that hybrid
Hummer or GM Volt can safely mix and match to almost any combination
of fossil and biofuels as your heart desires.

We're also talking about a fairly small radial turbine or some other
rotary efficient engine that's driving a direct coupled high speed
alternator. I suppose you've got those insurmountable problems with
that as well.

What's your sorry excuse for being such an all-knowing naysay stick in
the mud?
