No mention of microwave power transmission?
The article claims that the most efficient form of power beaming is a laser shining on photovoltaics. This can't be true. A rectenna is about 90% efficient converting microwaves to electricity (according to Rectenna) and, while I don't know the typical efficiency of a magnetron, according to microwave oven a microwave oven is typically 64% (700/1100) efficient so that sets a lower bound on the efficiency of the magnetron. Those number give a lower bound on the efficiency of microwave power transmission (ignoring loss to atmosphere) of 57% (.9 * .64). --Flatline 15:24, July 27, 2005 (UTC)
