Unlimited power
The Mad Genius from the Bottom of the Sea
From the article:
From the article:
- Craven's system exploits the dramatic temperature difference between ocean water below 3,000 feet - perpetually just above freezing - and the much warmer water and air above it. That temperature gap can be harnessed to create a nearly unlimited supply of energy. Although the scientific concepts behind cold-water energy have been around for decades, Craven made them real when he founded the state-funded Natural Energy Laboratory of Hawaii in 1974 on Keahole Point, near Kona. Under Craven, the lab developed the process of using cold deep-ocean water and hot surface water to produce electricity. By the 1980s the Natural Energy Lab's demonstration plant was generating net power, the world's first through so-called ocean thermal energy conversion.
"The potential of OTEC is great," says Joseph Huang, a senior scientist for the National Oceanic Atmospheric Administration and an expert on the process. "The oceans are the biggest solar collector on Earth, and there's enough energy in them to supply a thousand times the world's needs. If you want to depend on nature, the oceans are the only energy source big enough to tap."

OTEC has been around for a while. Could happen, but no reason to think it's closer to market now than 50 years ago. Didn't Tesla try to do some work in this field?
