John Thank you for your flattering if inaccurate opinion. Before you can assess the feasibility of any sealing idea you need to know what the source pressure will do as the flow rate is reduced and the shear strength of the walls of the passage you are trying to block. I have a nasty

If I understand correctly, the proposal is to maintain or renew existing permafrost or ice plugs and covers The existence of a prior cap indicates clearly that the seal is viable. It's not necessary to contain a pressure, as the clathrate pressure balances that of sea water. The challenge is to

Dr. Salter, This came through yesterday and your cloud brighting effort came to mind. http://www.physorg.com/news/2011-05-scientists-links-biology-cloud-formation.html What would you think of spicing up the cloud brighting with this (* dimethylsulfid)* compound? I could see the bilge water

Michael I agree that small drops of dimethyl sulphide make excellent cloud condensation nuclei because I have complete trust in the work of James Lovelock who suggested it. However I am trying to avoid the need for any replenishment of consumables in mid-ocean. I would not be nearly as
