Comment: What got my attention was the Bloom Box. I've never heard of it before. It appears to work, as it has several well known corporations who are using it.
Anyway, there's not a whole lot of time to comment upon the Free Energy post linked above. I wanted to make note of the Bloom Box.
I don't understand the Bloom Box, you see. I need to get up to date on that. If it looks good, I will have something to post about it later, time permitting.
The Bloom Box uses Scandium, a rare element, usually found with Rare Earths. These can be found on the moon. They can be found on the Earth as well, but evidently not in great abundance as I quote from Wikipedia:
The absence of reliable, secure, stable and long term production has limited commercial applications of scandium. Despite this low level of use, scandium offers significant benefits. Particularly promising is the strengthening of aluminium alloys with as little as 0.5% scandium. Scandium-stabilized zirconia enjoys a growing market demand for use as a high efficiency electrolyte in solid oxide fuel cells.
What about making Scandium? You can try to make it from Calcium, if you have neutrons. But that looks to be easier said than done.
Just conquer space and all this stuff will be in such abundance that you won't know what to do with it all.
