PAINT that could generate as much electricity as 50 wind farms is being developed by Welsh scientists.
Materials experts at Swansea University are working alongside steel giant Corus on developing a method of spraying solar cells onto steel used for cladding buildings.
If the work is a success it could lead to houses and offices becoming giant solar energy converters powering their own lighting, heating, televisions and computers.
And if the material was sprayed onto car and lorry roofs they could eventually use solar power to split hydrogen from water.
That would allow vehicles to be powered by hydrogen fuel cells at no cost to the environment.
Unlike conventional solar cells, the materials being developed at Swansea University are more efficient at capturing low light radiation, meaning they are better suited to the British climate.
