Thinking outside the box coming from studying and learning more about basic physical properties of water - I like it! It sounds like there's a long way to go to develop collectors, and determining how efficient they would be, but anything to add to the repertoire of renewable energy production, especially in areas where solar or wind isn't as feasible, is all good. Thanks for bringing this to attention!
"Now, more than ever, the illusions of division threaten our very existence. We all know the truth: more connects us than separates us. But in times of crisis the wise build bridges, while the foolish build barriers. We must find a way to look after one another as if we were one single tribe.” -King T'Challa, Black Panther
The truth is incontrovertible. Malice may attack it. ignorance may deride it, but in the end, there it is. ~Winston Churchill
