Re: Solar powered cooling
"They were even touting it as more environmentally friendly than any of the new freon replacements. "
Absolutely! When a rr car full of ammonia derails and spills, it may kill a thousand people, which is good for the environment. And it certainly won't hurt the ozone layer. So unless you count living creatures as part of the environment, ammonia is absolutely great compared to "Freon".
Odd that Danfoss doesn't offer ammonia systems for small craft, isn't it? [sic]
