I believe it will happen one day, give it 20/30 years and it will be all the go. Better batteries/alternators/electric engines and more than likely, powerplants we can't even imagine today. Open up your mind and be prepared to venture beyond the square. Who would have thought 100 years ago, we'd have television 50 years later or mobile phones with video conferencing. There would have been rules back then to say it couldn't be done. Regards Milton

They don't need to invent perpetual motion for electric vehicles to become a viable alternative to a petrol/diesel vehicles, what they need to do is improve efficiency so that an electric car has a usable range of around 400klm+ and can be fully recharged in about 30mins. When that happens electric cars may be useful for other than short city commuting. Daryl
