I sell $5 Construction Plans for Blood Electrifier, two plans are included. One is super simple and uses only three batteries as its power source and is a DC current unit. The second one is with controllable output current at AC line frequency (50 or 60 hz) or at DC current (selectable by switch). US Patent 5,139,684 (of Kaali & Schwolsky 8-18-92) proposed using small bio-compatible amounts of electricity on the blood to deactivate all virus, bacteria, fungi, parasites therein. They made this patent after seeing a 98% deactivation of HIV in a test tube that was subjected to small amounts of electricity. (see experiments.html) Sine wave output. Powered by AC adaptor.
