INTERESTING... and a bargain for Western Society, but there could be a less costly alternative. Another possiblility, assuming that space robotics is perfected for use with Hubble etc. and the international space statioin can be adapted for such is the capture - and then the conversion over time of a meteorite into the appropriate sized nano-powder which can then be dispersed robotically at the appropriate altitudes. "Orbital Capture of Meteoroids in Grazing Earth Encounters" http://www.aas.org/publications/baas/v26n2/aas184/abs/S1404.html This does happen naturally periodically but we would have to be prepared to act quickly to stabilize the orbit and attach robotic mini-factories to the meteroid. Not Sci-Fi any more... more like a survival imperative if something else does not come along soon to save us from oil addiction. Jones
