filter salt water from the oceans so that the treated water can be piped or transported to the States in need ?

Desalination takes a lot of energy to do. So the costs for the current equipment is ok for short periods and small amounts (hundreds of gallons per unit not hundreds of thousands). These units are very good and do quite well at the coversion, but they do use a lot of energy.
While these units are readily available there is the added costs for not only the initial conversion but the transport which covers hundreds of miles. The required amount of water is beyond anything in current use.
Someone would have to build a large scale unit that uses that latest energy sources otherwise too costly to run. Piping to large storage facilities would be required as transporting water is costly.
Unfortunately the area that requires watering is very large and requires millions of gallons every week. Very large scale operation. Who would you make pay for it? At what price?

Solar stills could create plenty of fresh water and fresnel lenses would speed up the process....the main problem is transporting the water to areas that need it in sufficient quantities. I imagine a solar still floating in the ocean or in a man made lake that can produce the fresh water and eliminate the salt residue would be the way to go. As always, price considerations are very important but we do have the technology today.

Desalination of sea water is very expensive, from an energy standpoint. I grew up with a desalination plant providing water for many years to our community. But it was experimental.
There is plenty of water in the ground, and it is constantly being made anew from rock, deep in the earth.. Our job is to find it and use it wisely. Industry uses by far the most, but they need it to provide the goods and services, plus jobs, that we need.
I agree, maybe more effort should be put into finding ways to get it from the oceans, but by industry, not government.

The technology is already there. That is why they are desalination plants in places like Hawaii and Saudi Arabia, but it takes alot of energy. Also, there are many environmental concerns in desalination. See this wiki article

water is most abundant in air , sea and ground water
it is up to authorities to tap these resources to use
I don't know
