This is a follow-on posting to the "Future of Free Energy" thread and this video and PESN entry:
http://peswiki.com/index.php/Directory:James_D._Hardy%27s_Self-Looped_Water_Pump_and_Electricity_Generator ... which most observers here have understandably written-off as a fake of some kind. In fact- the device itself is almost a humorous paradigm for the kind of Rube Goldberg ("impossible") contraption that symbolizes the legions of 'untaught' inventors like Joe Newman etc - who are (negatively) associated with the field of alternative energy. The video could easily be faked, but in the spirit of giving the benefit of the doubt to unsophisticated inventors who 'seem' sincere, and claim FACTUAL self-power, and not theoretical BS - here is more information which may be helpful to those planning on an eventual replication attempt. Richard Macaulay, water-expert-emeritus, who I hope will be an impetus for a replication at the Dime Box Labs, will get a kick out of the following ... and he is probably one of the few vorticians as few understand the two distinct sides of "cavitation" as well. This- despite the fact that cavitation can tear up steel impellers with great haste. That is the downside of the high level of 'hidden' (and usually destructive) energy which can become "free energy" - perhaps if engineered and applied constructively. The fact that Griggs et al. never could prove it conclusively, despite the copious anecdotal evidence, weighs against this conclusion ... but yet hope lingers on. Now for the possible upside of cavitation in pumping situations (sonoluminescence and beyond): First, here is a decent master's thesis on bubble-pumps http://www.me.gatech.edu/energy/SusanThesis.pdf ... but it is focused on the "heat" version of this type of pump. IOW steam bubbles from applied heat, which do the pumping. This is often said to be "inefficient" for pumping, compared to mechanical pumping- vut is a short-sighted way (when you do not consider the inefficiency of grid power) The heat version is sometimes called a "Geyser pump", because it operates the way that natural geysers work to pump water faithfully ;-0 The kind of bubble-pump which is used in the oil-patch to get out the thickest crude from nearly depleted wells is often called an "air-pump", although these days CO2 is used instead of air since it can actually thin the crude in viscosity - through its solubility, while still allowing lots of surface tension (which is what allows a *form of anti-gravity* to do the pumping. I am deliberately conflating anti-gravity with phase-density and buoyancy. Why? Well if buoyancy can do pumping for free, then yes it is truly an anti-gravity effect. How that meshes with the LoT is of no real concern here. OK to end this first part (if I still have your attention) please watch this video with the understanding that the cavitation bubbles which are seen can be deliberately introduced and intensified through micro-channels in the impeller - and guess what? they actually can make the pump more efficient *mechanically*, even without their possible buoyancy effects - when you imagine the video is rotated 90 degree! http://www.youtube.com/watch?v=GpklBS3s7iU Stay tuned for page two. I wish I could add the voice of Paul Harvey here. Jones
