Whoah there Clive.......
The wonders of electric cars, flying or not, forever seem to cover up the truth about them - they're no more eco friendly than the trusty combustion engine.
If we all go "Electric", where do we get the 'juice' from? From coal fired/oil fired/gas fired (or worse still) neuclear powerstations. Yeah, that makes real eco-sense....NOT!
Maybe we'll all have little windmills mounted on the bonnets? Hey, what about those dumb looking hats with the helicopter blades on them? Maybe Sir Clive could programme one to take us wherever we want???
... and no - I'm not a tree-hugger, just well and truly pissed off with all these "lets be green and have an electric car" types. And as for fuel cells - oh sure, pumps out H2O at the back end, but how much power did it take to actually charge the cell in the first place, never mind build the vehicle....
The only true eco friendly power source for cars is either to WALK, CYCLE or if you must have 4 wheels; go solar powered.
grump grump grump, moan moan moan.
