Range extender for Tesla
I know Tesla will never have a range extender in their cars.
Till now, the best range externder was announced for Audi A1 E-Tron. Small Wankel engine below the back seats as secondary engine.
Or this one from 1979 : http://green.autoblog.com/2006/05/02/stirling-engines-time-for-a-comebac...
Even better solution would be super powerful RSE Rotary Stirling Engine, which would work on any kind of fuels, solar heat, or both at the same time. Of course it would work in silence at high RPM, only to recharge the batteries. Range of these cars would be 2000 miles.
