Comments on Solar Power Satellite via Arbitrarily Large Phased Array
'This was really free power, easy power, plentiful power.' (Read
the complete story)
| "So I guess air traffic will have to routed around these beam zones?" (duG 4/18/2012 2:43:09 PM) |
| "It's the leaves that gather solar energy; not the petals." (Peter Jacobs 4/18/2012 3:38:28 PM) |
| "Ha! Peter, that snuck in from the physorg article, which said 'the common flower, which uses its petals to collect solar energy.' And after I noted it in my article, I thought to myself 'hey, that's not right' and then I found the link to the NASA site and never came back. Thanks for reminding me, I'll fix it. Oh, and duG, if an airliner flies through the beam, think of a moth flying through an industrial laser beam..." (Bill Christensen 4/18/2012 7:48:57 PM) |
| "Well, even on a cloudless day the atmosphere absorbs at least 10% of the Sun's radiant energy, and more when it's cloudy. And the Sun is below the horizon nearly half the time, but if you're in a high orbit it's visible all the time. In space near the Earth, the power available from sunlight is about 1000 watts per square metre. If somebody could invent a cheap, efficient and safe way to transmit solar power from orbit to the Earth's surface, it would provide much more power than panels on the Earth's surface."
