More cloud seeding power? RE: [geo] Power-generating system to transfer heat from Earth to upper troposphere

Svetlana, Your concept may combine well with Dr. Salter's cloud seeding ship approach. Check with some stakeholders in ship propulsion systems - the people making kite sails for cargo ships, California Air Pollution Control Board, cargo ship operators. Have handy some dimensions for the 1MW and

When Hamilton says, One of the foremost is of course that it’s likely to cause political leaders to weaken even further their commitment to Plan A, I think he's pointing to a danger just as great as the risk that we'll screw this up, e.g. by triggering nasty, unforeseen side effects. The only

This is not actually correct. They found a 1.5 K cooling averaged over a 30 year period. I am not an expert in their science, so don't know what the error bar is on this, but this does not preclude a very large cooling for 5 years which could have been catastrophic. Alan Robock Alan
