I just heard about a Japanese group of scientists that successfully transmitted 1.8kw of electricity wirelessly a distance Of 170 feet using microwaves. The dream is to have massive solar collectors in earth orbit transmitting an inexhaustible supply of electricity to the surface. Sounds cool but a couple things: how would these collectors be built and maintained? If the power is to be transmitted via microwaves I can't help but think of the movie Real Genius...
Thoughts?

How do i know you guys are old?
Because you talk about 1985 movie as if it was out last month 🙂
On a serious note, how efficient is the Japanese's transmission?
Couldn't find it on the news links i found.

I remember this idea, SPS/Solar Power Satellites was in the newspaper in the late 1970s. There was lots of discussion. The beam intensity on the Earth's surface would supposedly be low enough that it wouldn't hurt people or animals if it got off target (but then this would mean it needs a huge target to receive the power). Th buzzword for the antenna/receiver is rectenna, and I don't offhand know how it works.
One of the fears was the Soviets could send up something to destroy it.
Looking at the Death Ray link, it's a building with a concave side - what could possibly go wrong???
Who you callin old Kiddo?
Haha. Just joking. I don't know about efficiency either but there has to be some loss right? I bet Tesla would know! After all he did this first.
