In answer to your three questions:
1) The electric grid is far under capacity at night, which happens to be the time when electric cars would be charging. So YES, the grid can handle
2) Quick charging becomes more possible with each passing year. The first electric cars took up to 50 hours to charge. The Tesla Roadster takes 3
1/2. With improvements in battery technology faster charging is possible. A company called Altair Nano has a battery that they claim can be charged
empty to full in less than 10 minutes.
Don't think of charging your car in the same way you fill up with gasoline. You won't need to stop at a station and energize. You do it in your
garage while you're sleeping.
Another option in the future would be to have pre-charged batteries available to swap-out at stations if you want to make a long trip. Battery sizes
and shapes would need to be standardized, but that's not difficult.
3) Spent batteries are recycled. No differently than aluminum cans or the old tires you replace with new ones when the tread wears out. Recycling
in the auto industry happens all the time... batteries will be no different.
Electric cars are not popular today because they are TOO GOOD of a solution to the problems. Here are two big reasons why:
- Electric cars have far fewer moving parts. Maintenance and garages are a large part of the income for the auto industry. Think about it: oil
changes, spark plugs, coolant, transmission fluid, air filters, belts, hoses, exhaust, mufflers, brakes... the list goes on. None of this is needed.
The ac induction motor is essentially 1 moving part, and the bearings can be replaced very easily. The motor itself could run practically forever
with replaced bearings... literally millions of miles. All that other junk doesn't exist and isn't needed in electric cars. Less to break = less
profit from fixing it. This is why auto manufacturers don't like the idea... a lot of their money comes from the fact that the internal combustion
engine is complex and prone to breaking.
- They use far less energy to get from A to B. The internal combustion engine is only 33% efficient, at most. Electric motors are 90% efficient.
The reduced demand for fuel is something that takes power away from those megalomaniacs who would like to rule the whole world by being the sole
provider of our lifeblood. With electricity, it doesn't matter how you generate your power: oil, gas, coal, wind, biofuel, ethanol, solar, nuclear,
cold fusion, or moonshine... the oil monopoly strangle-hold is broken.
As you can see, with everything else in life it always comes down to money. In this case, it makes very GOOD financial sense to use an electric car
for US, but for THEM it's very very bad news. This is why progress is so slow or non-existent.... most of the companies who could build them don't
want to, and they either drag their feet, ignore the idea, or argue against it.
The good news is that this pressure is building up like water behind a dam. Everything we have been denied is coming to the fore, and increasing in
intensity. They may have been strong enough to delay progress but there are simply too many things going on all at once now to hold back the tide.
When this thing breaks, it will be a flood.
One last thing - there is a documentary style video out there called "Who Killed the Electric Car?" This tells a good story of the evolution of
this vehicle, and shows clearly the ins and outs of why we need these in the country desperately right now. A very good watch, interesting and
