I simply do not understand california's water shortage problem. They are by a frickin ocean. It's sunny nearly all year round. Solar powered or wave powered desalination is a fairly straight forward solution to this problem.

Desalination is incredibly expensive. At this point, they aren't completely out of water, as the crisis continues desalination will become more viable (expensive or not, people need water to survive).

It's technically possible, but not at the right prices. California has been supplying water to agriculture at below market prices.

We learned yesterday that 80% of water consumption in California is by agriculture[1]. Yet this executive order does nothing to reduce agriculture's use of water[2]. It only refers to use of urban water, lawns, landscaping, and cemeteries. Agricultural users just need to submit vague "plans." 1. http://www.thedailybeast.com/articles/2015/03/30/how-growers... 2. http://gov.ca.gov/docs/4.1.15_Executive_Order.pdf

This is where Amdahl's Law meets real life.

Yeah it seems pretty crazy that they are targeting the smallest sliver of water use for restrictions. I'd think we would want to limit the restrictions on everyday citizens and focus on the farmers who are fewer in number and, I would assume, easier to control as a whole than every citizen in CA...

someone has to protect our poor farmers, everyone loves farmers.

People have had water for a fairly low price that nobody really cares about it. Now they have to care, but it's not the end of the world (yet). Solar/wave powered desalinization will look a lot more interesting when they hit bottom. Unfortunately nobody will move before it reaaaaally hurts them.

Because the real problem is inland, so as well as desalinating the water (which is somewhat easier said than done, though I agree in principle), it would have to be pumped inland and mostly uphill for millions of miles.Our state water infrastructure is ancient, we just last year secured passage of a $9m bond to overhaul it, despite the vociferous objections of the farm lobby.

Here's an article that goes into the complications and controversies of desalination in California. http://www.mercurynews.com/science/ci_25859513/nations-large...

These plants seem to be self-sustaining (they even create extra energy) and can provide potable water from the oceans:
