 This is a current project that I have been working on for a couple of months now. Basically, it is being done as I can afford to buy the parts.  These pictures are not in any real order. They are just various pics I have been taking while building.

  I got the engine to work but I couldn’t
  supply enough hot water with the
  panels I was using. I could only get a
  few rpm.  If a good source of used hot
  water was available the engine would
  operate much faster.
