[extropy-chat] FWD [PvT] Re: Anti-hurricane engineering

[Mike Lorrey]

Hurricane damages are typically counted in the billions, just from when
they hit the US shore. $2.7 million sounds more typical for the damages
to a carribean island.

Killing the hurricane entirely really isn't needed. What is needed is a
way to downgrade them from cat 4 or cat 5 status to a 1 or 2. If you
have some tankers with jet engines on board, burning fuel and pumping
air to depth along the track of the storm. Reducing surface
temperatures by only 5-10 degrees goes a long way to detuning the force
of a hurricane.
