Refrigeration, air/cond: would this work? Use the force of rising ocean waves as a piston in a cylinder for a?

Air cooling and ice making has been around for years. The problem with air is that while you can compress it and run it thru a heat exchanger, it must perform work to get really cold. Airliners use a stage from the engine compressor thru a heat exchanger leading to a small turbine, and the turbine exhausts into the cabin. The work done on the turbine and its load (usually a fan) is at the sacrifice of the air's internal energy, so the turbine's exhaust is cold. Drive a load with your ocean compressed air, use the exhaust, and it should work.
