Great idea

True innovation. Best of luck to the company.

Note, shouldn't "Pressurized water from the facility passes through a turbine, and the turbine produces water." actually read "and the turbine produces electricity"?

45 PSI high? And old idea.

Um, we had a pressure test before we bought our house and came
up with 50PSI, my plumber tells me flow restricted shower head
flows are measured at 120PSI which is the high end of home water
pressure. I put my face right under the shower withour 50PSI water
pressure and it feels great!

I believe small scale turbines for the home even exist, they also
have ones that can be put into steam heat systems to take
advantage of the steam pressure.

90 PSI at my house- no welts

agreed, but still a neat application.

END MOUNTAINTOP REMOVAL ! There's a better way. Appalachia can't stand anymore of the progress and prosperity thanks to our congressman ( Rick Boucher ) and THE NEW AND IMPROVED, CLEAN, CREEN, HYBRID COAL INDUSTRY. See for yourself what is "clean coal". Wise County is being decapitated all for greed. http://www.wisecountyissues.com/?p=138 The only thing different about their vision of "green" is the politicians and profit machines stick it in their pockets.
