The Mosquito Coast reference is mentioned on the main blog here.
The idea for this post began with the basic idea from this link: "There's no such things as clean energy".
There's no comment upon the clean energy assertion, because there may well be an almost totally clean energy solution being developed right under our noses. It's called Focus Fusion. Focus Fusion is aneutronic, which mean that no neutrons are emitted. This is clean because there's no destabilizing neutrons that will cause succeptible atoms to go radioactive. This means virtually no waste. There may be SOME, but hardly enough for anybody to worry about, but purists undoubtedly will complain about ANYTHING.
It may be true that there's no totally clean energy source, but this one is about as close as it gets in the real world. All radioactive emissions are put to use, and there's no waste. Only helium molecules will be produced. The results will be limitless "clean" energy for millenia or even into perpetuity.
Of course, the technology is still under development and may not pan out. But the latest results are quite promising. We'll see.
With respect to the The Mosquito Coast scenario, we've already had refrigeration since before widespread usage of electricity. An energy source applied to a Stirling Engine will produce cryogenically cooling power. A Stirling Engine only requires energy. It could use sunlight, fire, or basic animal power to drive the device. Stirling Engines have been around longer than steam engines. They can be used without any "greenhouse" emissions whatever.
Or they could be power with an aneutronic fusion device like Focus Fusion. It would be very, very clean; and very, very efficient. Better than solar, but that would be faint praise.
Focus Fusion has a fundraiser going... If you want to invest, remember this: this could be a trillion dollar invention if it works. Disclosure: I own 1 share.
