Taking my time to read this post was worth with. The source of energy being discussed are justun unusual. In fact, I'm reading about majority of them for the first time. I was imagining if those alternatives were duly recognised and adopted, there won't be air and noise pollution emanating from the use generating set as rightly said by @ttopswag.
This is educating as I've added a new thing to my knowledge reading your post this evening.
Well-done sir
