@alfistii1 So how did the petrol get to petrol station? I would like some people to explain that from, how and where they pumped the petrol and delivered to petrol station. (how many things are involved?)
I don't think you can only get eletric by burning coal? so what are those wind turbine for?
Those can at least partially solve the problem of instanteneous charging for a short trip. Charging stations that hook up to low-amp power grids would accumulate electricity and discharge it into car's internal short-range super-capacitors. Should be equivalent to fueling time it takes at a gas station.
The best of the current super-capacitors could only provide the Roadster with something like 3 mile range. They simply don't have the capacity required as of yet. Now, if EESTOR's claims turn out to be true- then sky is definitely the limit. However, due to the lack of evidence, I seriously doubt that EESTOR will produce what they claim.
@f00kumofo123 Super-capacitors would be a great idea for a charging station, because as you said it would dump all of it's energy into the cars storage system, in a short period of time, but in a car a super-capacitor would be useless because capacitors have to discharge all their energy at once, where as a car would only need to use a little at a time.
@ekuwa69, discharge time depends on load, which translates to electric resistance. There is a formula that ties together the capacity, initial voltage, resistance and a time it takes to discharge to a lower voltage. With smart computer-controlled regulation, the engine can be made to run in a wide range of voltages.
My personal estimates for a discharge time of one hour from 5 to 2 volts for a 50-100 HP engine at approximately 10 MF - that's 10 Mega Farads.
Currently available MAXWELL capacitors provide up to 3 KiloFarads and future development can significantly improve on that. Say 100 KiloFarads / kilogram of capacitor volume translates to 100 kilograms of capacitance.
1 hour of drive is just for hard acceleration, which is a fraction of driving time, where there is also coasting, braking or sitting at traffic light.
75% recycable?? what about the 25%?

@nuen8 I guess you have to compare those numbers to other current automobiles. Is it more, or less recyclable.

Electricity comes form burning COAL at the powerstations, more electric cars, more
Coal burnt, how is burning fossil fuel any greener than burning petrol fossil fuel.?

Great presentation- thank you!

@TheBishopSSR besides EESTOR there are nanotube capacitors being developed to put into production.
Also electronically controlled discharge and smart voltage regulation will certainly improve driving distance.

Didn't mean such long post.

The only other things that need taken care of are electronics and appliances - heater / air conditioner and audio.
