Uncertain Times for DefenseIn Defense of DARPA; Lamenting Bell Labs
By Barry Manz

A federal agency like DARPA is a sitting duck for politicians and assorted other critics. It has come up with some truly bizarre programs over years that ultimately either delivered no tangible results, were canceled before they could cause any damage, or attempted to answer questions that nobody was asking or needed answers to.

Another Shot at “Energy from Space”?

Russia is considering building a giant solar-energy plant in space, from which electricity could be generated and directly transmitted to Earth using microwave energy. The country’s Central Research Institute of Machine Building, the primary scientific enterprise of the Russian space agency Roscosmos is exploring the idea. The first person to suggest this was American aerospace engineer and scientist Peter Glaser, vice president of advanced technology at Arthur D. Little (now retired), who formed Power from Space Consultants to explore the idea. The idea is that a huge solar panel covering several square miles in geostationary orbit is converted to microwave energy that is beamed to an antenna field on Earth, where the energy would be converted back to electricity.

The alternative of using a laser for the energy transfer is also being considered, although there are obvious drawbacks that would probably make this both prohibitively expensive – and potentially lethal. “The laser would have to have immense power,” says Russian Space Agency member Andrei Ionin, “to say nothing of the environmental impact for the Earth. God forbid the laser beam moves out of position. What will happen to the Earth then? We don’t know how such offsets may influence the ozone layer. What if the laser starts burning holes in it? “
