Geothermal Desalinization

Conservation of energy says no. That water picked up speed moving down the funnel, but now it has to get back to the top of the funnel, which means losing all that speed. There is no free lunch.

If you don't have to move the water far, you can use solar desalination effectively. This solar desalination project recycles the salty wastewater that drains out of the fields.

The above is a solar still. Below is what you described, which is different.

 

Because of Ocean Wave Swells Conservation of Energy say's yes!!

The idea is to have the bottom of the funnel attached to the sea floor then dig a trench inland from it to well below ancient sea bedsthus the water line coming out of the bottom of the funnel might be 1000 feet deep but as the California Coast is being SUBDUCTED under the Pacific Plate...the actual sea level 1000 feet down as ong as it is built on the uprising Pacific Plate would be at a sea level depth of perhaps 300 to 500 feet below sea level as where ancient ocean dry beds can be much lower in the California Desert.

The water would literally be running downhill if a channel is dug.

The only thing different is the one interior membrane is Water Vapor Permeable and the 2nd is not.

invent efficient cold fusion and cheap desalinization, and the world's problems and wars will be gone.

 

I sure like the sound of this...... simple... and cheap.......
especially after seeing Al Gore's second film the other night.
