Very interesting.
2/3 of the earth's surface is water...up till now it's 'just sitting there'...not much use.
I'm all for seasteading. This is a step in the right direction.
minor scolding. Don't believe anything your read about 'climate change' OR ' help prop up the failing coal industry'..that's bogus. Obama's reign of era made war on coal. Stopping the war doesn't mean 'propping up.'
I still don't like the taste of coal smoke in the air. I live too close to coal powered water heating plant.
I was heavy haul for decades. I hauled a LOT of scrubbers to coal fired power plants. When the exhaust from the burnt coal went thru those scrubbers...it was cleaned..
