  • Here, here! Great idea!

  • Just keep walking, Joe. This job is mine, and I’m going to milk it for all it’s worth!

  • Mr. Bill suffers from a relapse of his fear of public speaking.

  • I have to disagree with sultanblender. DON’T go public. If you do, you’ll be at the mercy of the shareholders instead of being able to blaze your own trail. Keep up the great work. I’m a huge fan.

  • A “small” correction here for caseyh: Compressors do not spin backwards during an off cycle in a refrigeration system, either residential Heat Pump or Air Conditioner or a screw chiller. During the first second or two after shutdown, it may spin backwards as it unloads the pressure on it (this is only true for scroll compressors, not reciprocating ones), however, it does not continue to spin while the rest of the system equalizes. Equalization happens as the refrigerant expands through a metering device.
    I like the concept, though. It is a resourceful use of already existing technologies. I would love to see more of this type of innovation.

No public wish lists :(
