Great if it is affordable. But I predict some three striped mud snail will be found in a runoff ditch and the enirostatists will shut it down.

No I think this is the real deal because an austrailian company linked to above is doing something similiar to heat and water greenhouses along their desert coast. The thing will scale nicely.
Corn needs about 1 acre foot of water to grow properly. Of course this is all dependent on soil type and environment and wind and temperature. If you can grow 150 bushels of corn under ideal conditions you are looking at $3.33 dollars of expense per bushel of corn in water that is produced by this method. This puts corn out of the question as a crop to be grown using this method of water production. The point is that this method is only viable for high value crops that need much less water.

If you look upthread to the beginning you’ll notice that I posted a link to sundrop farms in australia which runs a green house that produces tomatoes. The green house is along one of the desert coasts of australia. It gets its water and heat at night from a similar array as seen above and sells its tomatoes locally. They plan to scale up in the next year or so.
The above figure assumes the sun is shinning 23 hours a day: in reality solar only works well for about 8 hours a day. So, in reality, it’s going to take about a 20,000 square foot unit for 14,000 gallons a day. For an acre foot of water per day then, it will take a 47,000 square foot system.

Yeah I thought some of the numbers were funny too but if you look upthread to the beginning, you’ll notice that I posted a link to the sundrop farms in australia which uses similiar technology to heat and water a greenhouse along one of their desert coasts. they plan to scale up considerably in the next year or two,.
Wanna bet the EPA will give a thumbs down to this? It would make food control harder for obama.
Uh-uh. Not wise to bow down charmed before their expertise. This is a question any engineer would ask. Ask it. Don’t be satisfied until you hear the answer. Engineers succeed because they ask such things.
thats pretty efficient storage then to evaporate sea water for 8 hrs or so.
