well i have 3 computers and a ps3 . at least 2 devices are on virtually all day even if someone is not using them so i figure why not harness some of the 3.2x6  ,3.2x4 , 3.2x8 , 2.6x2  cpu power and the slied 470s ,260 , and 7900  folding power. medical tech is in leaps and bounds and we never know if we will help a friend family member or ourselves for the extra few bucks a month in electricity , imagine whet we would be if we could do this 20 yrs ago >>>>>>>> ..........
