Electric Vehicles

From time to time, travelling by car cross country can be ok. For daily commuting - highly undesirable, unpractical, without any real benefit.

Stirling engines

Mechanical/heat engines, suitable (more than other engines) to be powered with concentrated sunshine (free piston with built-in alternator especially), with interesting efficiency.

Batteries

Optoelectric nuclear battery · Lithium-ion batteries · Lithium-polymer batteries · Nickel-metal-hydride batteries (NiMH) · Flow battery Liquid battery big enough for the electric grid? is a form of rechargable battery in which electrolyte containing one or more dissolved electroactive species flows through a power cell / reactor that converts chemical energy to electricity.

Exchange of whole batteries in electromobiles at 'battery stations' - highly questionable.
