As you may know, I have a little hobby.
Flying electric model aircraft.
Up to tow years ago there was no way
to even approach the power and
energy densities of a tank of fuel. There
is now. And its tipped the balance so that
applied to cars, it comes out damn near
equal overall in terms of power and range
to weight of a tank of petrol and what is
needed to make it turn the wheels..

I can buy all I need to use this
technology NOW.


So, electric cars are "equal" to petrol right now in range and performance.
Apart from the zero emissions at point of use (brilliant as cities are
cleaned right up), what else is there to tip the balance? Generating more
electricity (very dirty procedure at present) at power stations is going to
produce more emissions. Cleaning this up is an expensive nightmare, not to
mention the electrical distribution system for re-charging vehicles.
