I can't remember if the array would go up in orbit or down in orbit but is sure wouldn't point at the recieving station for long. Wes |

When I was 'around' a very high megawatt transmitter - required a power plant
for itself - and had a 100' multiple ground screen that protected every one 'around' - but the birds in the wire and those inside were toasted! All aircraft were cleared from flying for a hundred miles or so while it was in operation. The real danger of beams is it wondering off target. The earth isn't a perfect top. It wobbles and turns. Land moves and heaves. Keeping the beam on target would be a task on top and bottom. Instant off isn't an option. If it transmitted down a carbon ribbon as in the sky ladder that is proposed it might be just fine. But not an electric beam. There are better turbans that the ones used - but the size is tough. Like a cylinder of vanes. They never got working a siphon in the ocean - where the cold and warm water siphon up a tube without pumps. Just add pipe. Now if pipe had vanes and alternator - and power lines - power source. Martin Martin H.

Ask the buffoons on one of the alt.energy newsgroup at the moment, as they discuss beamed power from satillites and how it would solve all of our problems. I was involved with folks who were working on a power satellite design. One idea being proposed was to set up the receiver station(s) in tropical islands, and use the electricity to generate Hydrogen. Not the most efficient, but nothing is 100% It worked on paper, but ... the company went bye-bye after 9-11. tschus pyotr -- pyotr filipivich "I had just been through hell and must have looked like death warmed over walking into the saloon, because when I asked the bartender whether they served zombies he said, ‘Sure, what'll you have?'" from I Hear America Swinging by Peter DeVries |
