Researchers develop reactor to make fuel from sunlight

Scientists raise hopes for a large-scale renewable source of liquid fuel with a simple reactor that mimics plants

23 December 2010

The key component is made from the metal cerium, which is almost as abundant as copper, unlike other rare and expensive metals frequently used as catalysts, such as platinum...

The device, reported in the journal Science, uses a standard parabolic mirror to focus the sun's rays into a reaction chamber where the cerium oxide catalyst breaks down water and carbon dioxide. It does this because heating cerium oxide drives oxygen atoms out of its crystal lattice. When cooled the lattice strips oxygen from surrounding chemicals, including water and CO2 in the reactor. That produces hydrogen and carbon monoxide, which can be converted to a liquid fuel.

Biofuels are a wide range of fuels which are in some way derived from biomass.

Your idea?
