Ahh, but the problem lies in accesssing the stuff. If you do exploratory drilling via a vessel and have an escape, the vessel will sink. Same for any type of floating platform. If you were to use a stiff leg derrick, it would need near infinite jack-up cpapbility that can simultaneously handle collapses as the reserve is depleted/mined.
I suppose horizontal/directional drilling could work. I wonder if production would require 2-way pumping. Heat may be required to liberate the methane from the hydrate form.
Very interesting idea. However, the enviroweenies will likely never allow such a thing, as the won't even allow wind farms on subaqueous terra firma.
