Water De-Salination

Water is the life blood of humans. Without it we can't live.

Fresh water is in very short supply, at least here in california.

A process called de-salination is starting to be used more to make fresh water from ocean water.

Primarily this involves taking ocean water and pumping it through membranes to remove the salinity and all of the minerals that may be in it. Lots of electricity is required to run the pumps that do this.

Here is a link to an article about this:

    1. Personally, i think that is a good idea. Maybe not so much for the cost savings. But, decentralization of the electric sounds okay to me. If the grid goes down they can still produce some water.

    2. What about geothermal? There's lots of free heat down there.

    3. That sounds good to me also, but you have to be able to get to the heat. May not be feasible everywhere.
