While all that may be true (I don't get the fabled supercharger bit) without certain people leading the way there would be no innovation. I'm sure
back in the day everyone with a horse mocked those who could afford a car. People hate NASA despite the fact that without them we would be living in
a very different world.
Let me backtrack on that supercharger part a bit. The whole test was meant to prove that the expensive novelty car can drive from DC to Boston using
ONLY the superchargers (2 of them installed on that route). And he would have made it but he spent the night at a hotel and overnight the battery pack
drained itself causing the whole issue.
These superchargers are basically bypassing the electronics that control the charge levels of the battery by injecting massive amounts of power
directly into the cells. It's like taking out your laptop battery cells and directly connecting them to a massive DC power source. They will charge
very quickly but in the process lose their ability to charger properly if done too often.
Tesla says you should use these superchargers and you will be OK on roadtrips but they don't tell you that this is going to reduce your battery life
and it's not covered by the warranty. These batteries are extremely expensive, I think around half the value of the car.
Back to the electric car - the only way we'll ever have a viable model is a replaceable battery system. I've seen a documentary years ago where the
car would basically drive over something that looks like an oil changing station and from below you had a lift that lowered the used battery and
replaced it with a charged one. Took only 5 minutes and would alleviate most issues related to supercharging or slow charging.
Overall the electric cars are something we'll never really implement unless we start living underground. Right now the exhaust systems of cars are
filtered by catalytic converters and computers so there's no more smog or dangerous stuff when you use the car in a city or the open road.
I'm not against the electric car but considering the amount of complexity that's being introduced by all these hybrids and the expense of
maintaining and repairing especially toward the end of their lives, as well as the final disposal of these hybrids - I'd rather stick with the good
old ICEs. The price of a regular gasoline car plus the gasoline plus the maintenance costs you less than a hybrid or electric and you don't save the
environment by moving the pollution away to a power plant or to some battery producer in Asia. It all comes from oil based resources anyway. Plus
think of all the losses from the electricity conversions, power lines and pure need to keep the battery warm overnight or cool during warm days - or
shipping the batteries from Asia to the US. How is that more efficient than burning the fuel right in the car?
If anyone wants to make a real difference to the environment then stop having kids, stop consuming anything other than what's strictly needed, reuse
old clothing, furniture, etc and minimize the use of the heating/cooling systems. But we all like to think that others should make the sacrifices to
save the planet while we keep our lifestyles and commute 40 miles daily (on average in the US) from our mcmansions to work... Feel-good lies is all we
get from solar panels and electric cars!
