There is a superb 15 chapter e-book by googling free energy info... chapter 1 page 9 gave info of a chinese device which just passed 6 month durability testing in April 2008. Said the device was hoping to be available december 2008! 3-4 weeks ago google searching the guys name came up with the company now I can't find it!!!
