Proposed artificial ring system around Earth to combat global warming-- along with "gravitationally significant sheparding spacecraft".
Anyone want to do the math on how "gravitationally significant" the shepards would have to be to maintain this? I'm thinking bigger than anything that could ever be launched from Earth, even in many smaller segments. http://www.livescience.com/technology/050627_warming_solution.html ______________________________________________ Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
