    Interesting technology. Energy is produced by temperature differences, so by my understanding, it would be more effective in colder climates since it’s easier to create a large temp difference? So conversely, it wouldn’t be as effective in a different location, say the tropics? Questions aside, that’s definitely exciting tech, I can already think of a few applications in mind. Cheers!
