It sounds too good to be true. Use warm and cool ocean water to make electricity, from a heat engine. The concept is good, it's been around for decades, but now it might be time to get serious.
Take a look at these 3 engineer-looking fellas on the right. What are they doing? Looking up the poop chute of a giant squid? No, looking at the water pipe that's part of a prototype electricity plant that uses ocean temperature gradients.
And here we go, it's Captain NIMO (Not In My Ocean) time again here on blogfish. Shall we consider ocean energy? Dismiss it immediately? Does Captain NIMO get to decide?
I think we need to consider it, because climate change may be a bigger worry than ocean thermal energy plants. OK, I'll admit it, my current prediction and guess is that climate change IS a bigger ocean worry than ocean thermal energy plants. So let's do the research and the prototypes in the right places, and figure it out as best we can.
