    i Really think

    This is not at all revolutionary. It's a heat pump. I think most of the comments about the article cover it. How do you patent that.

    I'm finding the first 12 years of the 21st century very dull compared to the leaps, and bounds made in the 20th century. Not at all what I imagined it to far.

    He invented that!

    its just a water to water heat pump, I use one to heat my home. I could easily use a three way diverter valve and make domestic with it if I wanted.

    I wonder if I installed 200 feet of black well pipe on the roof to pretemper my water, I could get a government grant too?

    There is a heat pump...

    ... water heater from Australia that captures waste heat from grey water. Called Nexus,  it doesn't have the potential downside of chilling water that will need to go for bathing.  It's still a new idea, but has potential.  Here's a link.

    Yours,  Larry
