On the other hand the interest to transform a mechanical energy in heat, even with a yield of 100% is rather limited ...
Except renewable mechanical energy ...
But there are surely niche industrial applications, where we can not directly heat the fluid directly for example ... for X or Y reasons ...
When the pump produces steam, the energy produced exceeds 30% that is supplied by the engine. However the advertisements of the company do not put emphasis on this on unit, they are content to announce an efficiency of 100% (mechanical energy in thermal).
This excess energy is connected to the speed of the rotor, the greater it is, the more the% increases and can even reach 60%
Explinations ?
- Most of the heat is obtained in a conventional way by mechanical molecular agitation, thanks to the friction of the forced current, and the direct impact of the shock wave which occurs in the cylinder.
- the amount of excess heat would come from the sonoluminescence, the excessively strong turbulence that is induced by the particular mechanical agitation produced at the same time cavitation and micro bubbles of gas. They are invaded by the powerful shock waves that occur when the rotor cavities pass by grazing the streaks of the stator, and they collapse then by releasing a lot of energy.
It is reasonable to hypothesize that a very small percentage of atoms probably corresponding to those of deuterium (the natural isotope of hydrogen) which is naturally present in water (especially at sea) eventually explodes into releasing heat
For 30% and more it remains to be demonstrated.
How much is "a lot of energy"?
I do not understand the last paragraph: atom explodes? Deuterium? Cold fusion?
This passage is also interesting:
A test performed by an expert in 1988 revealed a surprising result of on 10 unit at 30%. In addition, the pump eliminates clogging. Griggs also noticed, unusual effect, that there is a barely discernable fusion on the outside of the rotor, fusion that would require temperatures of the order of 1200 ° F, much higher than those produced by steam under high pressure. The tiny pieces of molten material bind themselves to the rotor (for this it would take temperatures of about 4000 ° F). In the Griggs hydrosonic pump, it is not just a water hammer effect that is at work.
It would not remind the pins on the stem observed by André?
Gaston as the accoustique is your domain, what do you think of all this? Notably the phenomenon of sonoluminescence (proven). Read or re-read this file: Science-and-Technology / sonoluminescence-or-sonofusion-t3155.html
ps: there was not a certain yannick who was trying to advertise such a "superunit boiler" a few months ago on the forums?
