New Scientist SPACE – Breaking News – New space prizes target space elevators: «The ‘Beam Power Challenge’ will focus on how to transmit power wirelessly by beaming radiation from a source to a receiver. In 2005, the teams will have to build a power receiver that can convert this radiation to electricity with photoelectric cells and lift a climbing robot carrying at least 25 kilograms up a 50-metre cable. Each team will get three attempts and the $50,000 will go to the team that can lift the most weight in three minutes.»
