>From what I gather, it seems we have a bit of engineering drama. Apparently, you can't just swap aircraft engines and do SRM, because the wings aren't right on any aircraft with even a vaguely adequate payload.
This is A Problem. We've either got to A) engineer a new aircraft, like the Delft team did (with a $100m expected development cost) B) work out a way to make new wings for an existing jet (not simple) C) come up with something else If we assume it's C, then there's quite a lot decent new hardware around. One choice is Blue Origin/Space X kit. Does anyone know how that would fare in an up-and-down flight path? I know Blue Origin did that before. Payload should be manageable, but I'm not sure how costs are coming down. Another alternative is one of the hybrid concepts. I got a flea in my ear for mentioning BAE systems hybrid engines before. However, their power in thin air may make them suitable for geoengineering use - either as zoom climbers or cruise. I know that current thinking is to condense H2SO4 directly, but I guess with any kind of zoom climb, you're pretty much stuck dumping bulk SO2 and crossing your fingers it doesn't all coagulate to baseball-size and drop out! Would be great to hear from people on the list. (Personally, my concern is that our best option for accessing the stratosphere at the current rate of engineering might be to make a large pile of climate engineering governance papers, and walk up that carrying gas tanks! There will soon be enough of them ;) ) Andrew -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
