Performance with lithium polymer cells is more than adequate - in fact
it is stupendous. Distribution of energy exists in the national grid.
Overnight charging would actually improve power staion efficiency as it
happens when other electrical uses are low, so power stations run
continuosly - much better for efficiency. The only unknown to me is the
energy cost and lifetime of battery production and recycling. But I
doubt it is worse than making e.g aluminium for car engines, or steel
for transmissions.

The cars are simpler too - all wheel drive with motors integarted into
the hubs, no need for gearboxes by and large, or transmissions. In short
its a simpler beast. One enormous battery pack, 4 motors and a bit of
power electronics. That replaces engine, cooling system, transmiision,
axles - in short most of the heavy bulky bits. No maintenance, apart
from replacing defective cells and so on. No oil changes, or plug
changes. Performance with most of te weight slung low under the cahssis,
and a motor on every wheel, with de facto traction control - its a rally
drivers dream come true. No gears to go, no clutch to go. And easy
access to better than 800bhp if you need it, or the ability to trickle
along at 90% efficiency at much lower power levels. £00 miles + range on
an overnight charge.


How about heating the car in winter? This would be a traditional electric
element, which consumes a lot of power from batteries. The car would
probably need a layer of insulation to keep heat in and heat out in summer.
Do the batteries produce enough heat to heat the cars cabin?



Oh, I am sure it ouuld be triple insulated to latest building standards
and heat by dint of the sun shining on it...
