ah yeah, if you can convert atmospheric oxygen to nitrates you can feed plants too, that's the main thing the sea has little of

well, it sounds like fun science but i'll still prefer the high prairie... i've always loved that kind of landscape anyway... i spent a lot of time in Sofia, Bulgaria which sits in the middle of a fairly large plateau about 600m and in several spots in the mountains around it there is thermal springs... i mean, i love that place but thermal spring, a little too close to the lava for my taste... in that region my preferred location would be nearby Rila mountain, Bansko, around there

here in Madeira the feature of mountains that is very handy is the way the rocks soak up and leak back out such a vast quantity of water continuously... it's mostly arid on the surface, but with a myriad of springs around and that water is perfect for drinking, almost a waste to be using it to wash but it is what it is

the most important thing, for your projects though, is that you have to consider that radio conditions may be so rough at times that you lose all that electrical infra and if that's the life spring there then you are in trouble, that's another thing about where i'm planning to head to - plenty of coal in the ground, plenty of carbon sources around
