I guess that picture of a leaking water pump is meant to inspire confidence in what you are promoting.  And yes I am sure of what I am seeing.  I worked in industrial maintenance for many years.  You can give that water pump a fancy name but it is still a water pump that is heating the water by the turbulence created in the pump cavity.

Yep,  Sure sounds like a cavitating water pump to me.  That sound like crunching up ball bearings is normal for a cavitating pump.  Of course the pump won't last too long being run like that.
