The University of Colorado at Boulder envisages an array of mirrors that would focus sunlight onto a central tower several hundred feet tall. The tower would heat up to around 1,350 =B0C - enough to liberate hydrogen from steam with the help of a metal oxide compound 'We have designed something here that is very different from other methods and frankly something that nobody thought was possible before,' said lead scientist Professor Alan Weimer --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
