#1 Interesting but it says nothing about how radio-requency transmissions to a receiving station in Fresno are converted to electrical energy. How does that work? Or does it? And if it does then couldn't anybody with the right equipment also receive those transmissions and convert them to energy, thus ripping off Solaren and PG&E? Is this a practical idea or a pipe dream?

#2 Big-ass antenna outside Fresno. High-power RF blanketing the area.

What could possibly go wrong?

#3 I see it as possible, but transmission losses for beamed power will keep it from being much more than a PR stunt, The transmission straight down is the problem, satellite to satellite have NO losses due to air dissipation.

(Beam spreading and length of transmission have their own losses)

But a beam powerful enough to generate enough electricity to use is a deadly microwave beam, all aircraft must divert or be fried.

#4 The detail,including the safety considerations were worked out by ~~space freaks~~ SD & Space enthusiasts in 1980es, mojo. Of course, between Soody owned pols and envirowackos, it'll never be build in USA---you'll just have for India and/or China to do it.

#6 What could possibly go wrong?

Nothing. Whatever did not go according to plan would only result in an improvement to Fresno.

#7 grom: And HOW big does the antenna need to be to reduce the power density of the RF to safe levels?...

Not saying it wouldn't work. I'm saying it'll never happen. Too much land tied up under the antenna, too many fluffy bunnies or spotted snakes displaced/inconvenienced, etc. etc.

We're talking California here.
