You know the old yarn about there is so much gold in so many buckets of seawater? This is flour gold and there may well be that much gold not that you'd be able to efficiently harvest it, unless it was a by product of another system such as desalinization.

how much “flour” would you get from seawater
as far as i know it is not normally found in seawater i think you would be getting a lot more gold than flour

According to Wiki, in North America during the day, between 1/6th and 1/2 horsepower per square meter. A square yard is approximatly 13/16ths the area of a square meter. What I meant in my first post is the lens is several orders of magnitude undersized in the illustrations. John Craig

With what you are saying, that results in about 5.5HP for an 8' dia. lens. However, is that a figure based on solar energy from solar cells or what? After thinking about that idea of steam power from a lens, it doesn't sound too far fetched as a use for home electricity/heat generation. But a deisel tractor? Hmmm...

The state of Georgia might want to look into the desalination system right now. There was a Popular Science article about the same time, maybe the year before, about an "air well" being built in France. Sadly that didn't produce much water, but the idea is well worth considering again in areas like GA with a lot of humidity and a shortage of water What a neat idea, and you get several benefits from one concept.
