pulser pump video (Simplest pump in the world)
If I were using the water flow to power the pump, why on earth would I want
to generate electricity and then drive a motor from it? Wouldn't gearing work? What am I missing - it must be something obvious .. May glorious Shamash make his face to shine upon you Gilgamesh of Uruk (Include Enkidu in the subject line to avoid the spam trap) "Brian White" wrote in message om... Well, OZZ, you will be wrong and wrong again without apology, Actually the hammer pump (also better known as a hydram) uses 60% or more of the energy DIRECTLY for useful work. Because there is no waste of energy in conversion, mechanical to electical, electrical to mechanical again, etc. it is almost impossible for a conventional electrically powered pump to come close to that 60% OVERALL efficiency figure! I have that info from an issue of scientific america. The pulser pump is a combined airlift pump and tromp. Please look that combination up in any book over 15 years old. You will not find it. Why? Because it wasnt there. Probably because it didnt exist. Low pressure airlift pumps are NOT well scientifically described. Why? They just extrapulated figures from high pressure airlift pumps. (I know because my pump easily beat their gestimates) They never actually bothered to make low pressure airlift pumps. Try to find information about pumping up an incline with an airlift pump. You will be a while! Yet it works. How good can it be? nobody knows. The good thing is that you are begrudgingly argueing about semantics. People are no longer saying that the pump itself is fake. It is a start! Anyway, low pressure tromps combined with low pressure airlift pumps have NOT yet been yet been described by science. There are interactions between the tromp and airlift sections which make the whole system quite a deal more complex to describe than the 2 devices working seperately. Finally, if airlift is so inefficient, why do people use vacuum cleaners? Wetvacs are clearly airlift pumps and it shouldnt be too much of an imagination leap to realize that dry vacuums are too. And feed trucks that blow animal feed into tall bins. That is airlift pumps too. As are many deep wells. That water in your beverage, might just have been airlifted! http://nxtwave.tripod.com/gaiatech/pulser/index.htm has lots of pulser info http://groups.yahoo.com/group/pulserpump/files/ is where the videos can be found. Brian White Oz wrote in message ... David Hare-Scott writes Both the air lift pump and hammer pump lift a proportion of water from a body of water that has a head over its destination without input of energy from the outside by using some of the energy in the head. You say both types are very inefficient. They are in that only a small proportion of the available energy is used for useful work. Whether that matters or not depends on the situation. Certainly neither can be considered as 'new' or 'not described scientifically'. |
