9. WRONG!!!!!

Natural gas is cleaner burning than either diesel or gasoline so take that out of your spiel, most EV's are charged at night when the power companies have to keep the generators running even though they don't have any market for it
===============================

First, gas isn't really cleaner that petroleum in terms of carbon emission. They all give you CO2.

It's a bunch of CRAP that power companies have to keep gas generators running at night.

Power companies use gas turbines, and gas turbines are really just jet engines with more turbine blades.

Do airlines have to keep the jet engines on their airliners running at night for some perverse reason?
NO!!

Additionally, a power company has to match the generation to the demand. If they generate some energy and it isn't used - where does it go? The grid doesn't store energy, and the Law of Conservation of Energy says that energy just doesn't disappear.

No - as electric demand changes during the day, and night, the power company has to MATCH that demand with their generation. It means that they throttle the plants to meet demand. If demand goes so low that they don't need a plant; they can idle it.

The ones that they idle are the gas turbines; because again they are just JET ENGINES!!!

I don't know who told you that jet engines ( gas turbines ) have to be run all the time; but they LIED to you.

I've read so much NONSENSE on this forum about generating technologies. I've had people tell me that the steam turbines have to turn at night so they don't warp. Power companies routinely shutdown power plants for days or weeks to do maintenance on the steam turbines. In a nuclear plant, that is done during the refueling outage to kill two birds with one stone. So how come the turbines don't warp during extended maintenance shutdowns, but they will warp over night?

Why would engineers design something that destroys itself if it can't run? Why would an engineer design a jet engine that had to be run all night when the plane isn't flying? Why would engineers do that???

No - engines are plenty strong to take the stresses that they endure during operation. Gravity is the WEAKEST of the fundamental physics forces. The only time gravity has a big effect is when there is a huge amount of mass like with a planet or star.

But engines support themselves just fine; like all the products in your house that you use everyday and don't have to keep running.

I think that most if not all heat the seats and steering wheel rather than the air in the vehicle madokie Mar 2012 #6
You aren't going to get away with cooling the seats only in the south.. Fumesucker Mar 2012 #7
Most of the time you'd pre-heat or pre-cool the EV before unplugging it txlibdem Mar 2012 #8
Taxing the batteries. PamW Mar 2012 #12
How is it taxing the batteries when the car is still plugged in? txlibdem Mar 2012 #13
You said the EV's would only have cooling for the seats and wheel.. Fumesucker Mar 2012 #15
