Re: Solar Power from Space: Moving Beyond Science Fiction

Geostationary is not the most debris-littered orbital level but it's not clean either. These solar sats, by definition, have to be large area and inexpensive. So I predict them quickly damaged, less power output, etc. Problem is that a debris hit can generate secondary fragments.

GEO has been the site of some spectacular collisions already. Perhaps it's better to reduce the current debris field before planning to launch new, giant 'targets'.

Wikipedia says there are already tens of millions of space junk.

On the other hand, lets launch lots of garbage and stop Global Warming!

Re: Solar Power from Space: Moving Beyond Science Fiction

Is the amount of solar energy loss through our atmosphere great enough to outweigh the additional energy COSTS to develop and mantain such a system?


Read a SciFi story where they had developed a series of solar collectors which were NOT in GEO orbit - but would transmit to specific ground based stations across the globe. with enough of these Small Sats - they could deliver power 24 x 7 to several locations. Could solve the Orbital Debris issue ( have them in a different orbit plane)

Re: Solar Power from Space: Moving Beyond Science Fiction

I don't think there is an orbital level or plane inclination that is free of (anthropogenic) debris any more. One of the most regrettable debis-creation events:

http://en.wikipedia.org/wiki/2007_Ch...e_missile_test

Unfortunately, that stuff is quite hgih and so won't get dragged into the atmosphere for a long time.

Y'all know that the int'l space station has to be moved to dodge chunks one to several times per year, yes?

Re: Solar Power from Space: Moving Beyond Science Fiction

Hi All:

___Besides the junk, I can just imagine one little screw up by a hit or some gyros going nuts and this thing spins off it axis even a thousandth of a degree and I do not want to be in the area.

___It would make one heck of a sci-fi thriller as a beam cuts a swath a few meters wide while cooking everything in its path for miles and miles

___Good Luck

___Wayne
