Abengoa said the project will improve its current solar thermal technology, which uses mirrors to concentrate and direct the sunlight for producing steam.

FORBES: Feds Fund Novel Green Tech For Electric Cars, Solar Heat Storage

This can be done by heating the gas (a thermal plasma) or passing an electric current through it (a non-thermal plasma).

ECONOMIST: Diesel engines

Photovoltaic panels use the sun's photons to make electrons hop around, producing electrical current, while solar thermal uses photons to move whole molecules--that is, to produce heat.
