February-The pump is installed and ready to go. should have results shortly. 

March 14-The new pump works however, it is a little slow so it needs some design mods. We are waiting to receive some custom designed electronics that will increase the flow of the HTF.

March 28-We should have the new electronic components in 4 to 6 weeks and the pump should be ready to shortly after.

May 5-still waiting for electronic circuits coming from China and the USA. We are working on a design of our own which will be simple and incorporate small DC motors collected from recycling.

July 11-the new design for the pump is almost complete. We will be bench testing the unit over the next few days. We created our own unique circuit to operate the pump to keep costs as low as possible.

July 15-Our own unique analog circuit is a little sloppy and has been abandoned. It is extremely difficult to get the timing of the reed switches just right so, we are now waiting for a new prototype PC circuit from Blue Point Engineering in Colorado that is being modified for our application. It will be low cost and is expected to arrive in less than 2 weeks. The other circuit from China was costly and we abandoned it. This circuit is a very important and precise piece and crucial to the success of the application.

Sept 1-still waiting for the circuit which is more costly than originally quoted. We have decided to test the pump manually using a 4 position switch for Proof of Concept before committing to the circuit.


February---new pump is being tested

June---new design works! waiting for parts to complete the design

December---new custom pump parts arrived and are being installed
