Free Water and Power.

Ok here's my idea for free power and water for everyone. Not sure where to take this, so I'm going to post it here and if you think you can use it, or make it work, go for it. To make this work you will need essentially 3 things, sea water, the sun, and a large mechanical contraption. The 1st 2 are essentially free, the contraption is a one time investment. As someone will point out I probably used too many commas, but I don't really care. Moving on, affix several parabolic mirrors in a circle, make sure they can be adjusted in a north south fashion (15 degree range should suffice), in the center place a large boiler, make sure your mirrors reflect sunlight at one spot on each side of the boiler. This should be done somewhere near the coast, you'll need a pick up line to get sea water, a turbine, a generator and some pipe. When you get done assembling your contraption should look similar to the illustration I've provided.
How it works: As you can see the water is trapped by a simple tidal tray, the pressure from the tide moves water down the pipe opening a valve in the boiler. The Boiler being heated by the sun quickly brings the water to a boil and causes the water to convert to a gaseous state forcing it to expand in the chamber. This gas that is forced out of the chamber is then fed through a turbine which in turn rotates a generator. The panels are moved slightly throughout the day to coincide with the rotation of the earth, so that their aim stays true to the boiler. After the gas exits the turbine it will need to be fed through some type of filter to collect whatever salt remnant maybe in the gas. The remaining gas should be pumped into an aquifer where it will then be allowed to cool and return to it's liquid state completely clean of impurities (distilled water). The boiler will need to be cleaned periodically of salt and other solvents.

Some add ons that might also work:

1. Natural gas heaters under boiler to supplement boiler at night so one could have a continuous charge.
2. Auto cleaning contraption for the boiler.
3. Possibly filter out some salt before it reaches the turbine to prolong life of the turbine.
4. New lubrication techniques maybe needed to deal with the corrosive effects of salt and water.
Quick notes:
The illustration is mock up of a device that is over 60' in diameter. Each mirror is over 6' tall, if I used the commonly accepted rule of Solar wattage (550 watts per meter squared in the North American region), this device at %30 efficiency could potentially deliver 7.3 kilowatts during peak time continuously.
Any suggestions or comments please let me know.
Again if you use this idea or like it in general tell people where you heard about it.
