I'd hafta disagree with this. By the time you added in all the
prerequisite circuitry, wiring, waterproofing, and extremely heavy batteries,
the weight would probably very nearly balance out...

Good points!. They are the reason the HEV team I am on is kind of stuck
with bad performance (0-45 in 13 seconds, 40 mile range, etc.). SIGH!
But here is a bit of trivia to show what EVs can do now.

Case in point: GM Impact - two AC Induction Motors
Sodium Sulfur Battery
Weight: around 2000 pounds (very rough).
Can't remember exact'y.
Acelleration: 0-60 mph, 6 seconds FLAT!
Top Speed: 130 mph
Range: 120 miles on one 6 hour charge
Target Price: 20-30K

The people who designed this also designed the FORD Sunracer.

This car is going into production in the next two years and is
targetted at the California area because of the zero emissions laws
that will go into effect in 1998. (10 % of ALL vehicles sold are to be
zero emissions (read that EVs). I think with demand like this already,
by 2053 they should have EVs down to a science.

On other EV fronts:

Vans such as the FORD EcoStar can have ranges over 200 miles.

Faster charge capacitors are the future of EVs. They can store in the
area of 10kW (kilo- watts) and charge in a matter of seconds. And they
weigh about 10 pounds per 1kW. These aren't available yet, but VERY
feasible.

Electric Motors are 95+% efficient. IC (internal Combustion) engines
are around 50% efficient. They are like blast furnaces. Electric
Motors have more torque at lower speeds. Better Acceleration is the
result.

FORD and SAE (society of Automotive Engineers) are sponsoring a HEV
Challenge for June. This takes HEVs (Hybrid ELectric Vehicles), which
are EVs with IC engines to extend the range, from 35 different
university projects and competes them. I am a senior member of the WVU
HEV project.

It is really very fascinating what is being done in the area of EVs
now. All I mean to do is show that today people are making EVs that
can REALLY compete with gas cars and that the demand is there for the
future of EVs to be assured. I don't mean this as a flame or an
attack. Please don't take it that way. If anyone would like to hear
more about this let me know and I will dig through some of my stuff
and get out some more interesting EV facts.
