Are We Air Conditioning the Wrong Thing?
An air conditioner removes heat from an enclosed space by using that heat to boil a working fluid and then dispersing the heat to a heat sink as that vapor condenses. About 93 percent of the heat of global warming is accumulating in the oceans; mostly in the upper few hundred meters.
Ocean thermal energy conversion works on the same principle as the air conditioner. A boiled working fluid moves heat from the ocean surface to the deep where the vapor condenses and the heat is transfered.
In the late 70s a team from The Applied Physics Laboratory at Johns Hopkins University, which advocated ocean thermal energy conversion, was concerned about the potential to start a new ice age.
Their analysis was 5 terawatts of power generated with this process would reduce ocean surface temperatures (and therefore the temperature of the atmosphere) by 1C each decade.
Since the stated objective is to provide energy while keeping the planet to a less than 2C temperature increase, this is the way to do it.
The potential exists to keep warming to zero this way and draw down CO2 levels in the same process.
We can either condition the oceans to produce energy or consume a great deal of energy, producing more heat, conditioning our homes and offices?
