Water!!! The answer!!!

Water is needed to sustain life on the planet. The world is 75% water, but only a small ever decreasing amount of that is actually clean enough to drink. I am constantly exploring how we can make sure that we have enough clean water for life to thrive.

I became aware of the water crisis that is facing the world when I saw the movie "Cadillac Desert" which is a documentary based on the book by the same name (I think I was 12ish). This concept was greatly enforced after spending time in Los Angeles and learning about the challenges they continue to face around having enough water. I will just mention a couple things about the Los Angeles water crisis. First: Los Angeles was built on a desert. And second: Los Angeles relies heavily on water from the Colorado river (severely endangering life downstream that depends on the river). Lastly: Los Angeles is by the Ocean. Now, it is commonly understood that the Ocean has lots of water in it, so why not use it? The answer is a mixture of economics and lack of creativity.

One issue to face:

How do we turn Ocean water into drinking water cheaply?

The answer:

Desalination(removing salt and other minerals from water) through distillation with the use of Sun light concentrated in parabolic dishes!!!
There it is. Very simple.
Not only will we be able to create clean water with distillation, but we will also be able to create renewable energy by using the steam from the the water to power turbines.

Los Angeles plans on increasing their use of desalinated water by 15% in the next decade, but they are looking at reverse osmosis as their primary form of filtration. Maybe they are being creative, but there are still elements of profit being the motivator.

I need to get to bed, and I know I didn't give many details, but I just wanted to get this out there. I have been studying this issue for a long time, so if you have particular questions, please ask.

My motivation is Sustainability, so I feel obliged to share ideas that will promote it. And please feel free to spread the word, as well as give me feedback.
