Persistent Optical Wireless Energy Relay (POWER)...

[Fred Bloggs]

DARPA is working on the next leap forward in energy distribution by leveraging wireless power beaming to create a dynamic, adaptive, speed of light wireless energy web. The goal of the Persistent Optical Wireless Energy Relay (POWER) program is to design and demonstrate airborne optical energy relays. These relays are a critical component necessary to allow ground-sourced lasers to be coupled with high-altitude, efficient long-range transmission. Additionally, such relays will enable future multi-path wireless energy networks.

Guess they figure trillion dollar deficits are not enough...

What they are talking about is sending enough power in tightly focussed laser beam to give a flying platform enough energy to do something useful.

Relaying power that way is hopeless - the end to end efficiency of a single hop is poor, and getting useful power out of the second stage would require an impossible amount of heat dissipation in the first stage.

The public relations clown who wrote that press release didn\'t run it past the engineers.

If your power source is a lot of solar cells in orbit

you don\'t need to relay any power - you just send it straight down to your flying platform.

That\'s actually the scary part. They did run it by the \"engineers.\"

More likely physicists posing as engineers. I met a lot of them around Cambridge UK, and torpedoed at least one - more or less unintentionally - by asking how he dealt with the power dissipation in his magnetic lens. His boss really didn\'t like his answer.

Fake people doing fake work.
