Thank you IronWood!
A very interesting & informative video.Of course the video leaves alot to guess work but I had to wonder at why these apparatus were not in general useage?

fundalmentally the pump induces cavatation => the drum produces pressure differential forming gaseous pockets => utilization of phase change absorbs heat (entropy) from water & friction.
quote:
pump rotors tend to melt (plastic) or freeze (metalic) when ran without water to cool them. Note that calometeric of heat to temperature changesform a generally a linear function till phase change occurs at which point rise in temperature stops till the phase change is completed.
Strange thing the video feed stop just after I added this last moment? Hmm . . . maybe sometime I will see the rest of it, althought I did see most of it this morning . . .
