These planes cannot reach the sub-stratosphere at all.
Gregory Has anyone looked at using firefighting planes to deliver aerosol particles? -----Original Message----- From: Andrew Lockley <[EMAIL PROTECTED]> To: geoengineering <geoengineering@googlegroups.com> Sent: Sun, 7 Dec 2008 5:46 pm Subject: [geo] delivering aerosols Has anyone looked at using firefighting planes to deliver aerosol particles? These are designed to spray powder. There are a lot of them about in Northern latitudes, and for much of the year they really don't do a lot. I've seen several other methods, all of which have disadvantages: 1) Space lift - still scifi 2) Balloons - could work, but would have to be hydrogen, not helium due to the volumes needed. Unless the balloons are programmed to deflate and float back down, there will be a lot of 'litter'. To get a decent payload, a very large flammable balloon would be needed. 3) artillery - possibly useful, but may be a lot more polluting, expensive and energy intensive than a plane. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "geoengineering" group.
