A Bit of History on Jupiter’s Technology​

 

Ross Sinclaire, the inventor of this technology, started his business career as a mechanical contractor, he developed a company which grew to be one of the largest mechanical contracting companies in Calgary.  As mentioned in previous sections, he was constantly re-designing mechanical systems. When he left this business and began looking at the tidal power business, his inventive mind told him that there had to be a more cost effective way to capture the energy in these tidal flows. Ross always believed that keeping things simple was the way to success, and many times that involves using tried and true concepts and using them in new and innovative ways. The Archimedes screw has been used by mankind for well over two thousand years. Putting it at an angle to the flowing water has proved to be a very efficient and cost effective way to generate power and it also turned out to be something that could be patented. In this case, the patent concepts are also so simple that they are impossible to get around and still produce anywhere near as much power. The experiments that Ross conducted began in the local river with a small augers to show the concept had merit and to find the best angle and pitch for the first real test of this invention. In the summer of 2012, the first prototype designs were built and taken to Vancouver for a test run. The data gathered was enough to get The University of Calgary involved to do further modeling and testing. Two U of C tests were conducted with 75% of the test cost paid for by IRAP, an arm of the National Research Council.

The test unit below is a V-shaped unit with the two screws both at 30 degree angles to the flowing water. This unit was submerged below this aluminum boat and both were pulled together by a tug boat, first in one direction and then in the other. We found that it made equal power whether the water was hitting the point of the V or going into the open part of the V. The power was dissipated by putting it into the 1000 watt baseboard heaters attached to the wooden frame on the boat. The screws were connected to 5 kW permanent magnet variable speed generators. Please look at the video.

First Vancouver Test Runs

Please note that this video is over 5 years old. A lot has changed including our name and where we now intend to test our first commercial sized unit (see the Home Page). It does show how determined we are and we are still convinced that our technology is 2 to 3 times more cost effective than the competition.  Enjoy the video.

​Jupiter Hydro built additional prototype units, always learning from previous tests. In the next tests, we used wider diameter screws with less length because we felt they would be more efficient. We also decided to experiment with plastic screws. In the University of Calgary tests mentioned above, we were able to confirm that the best angle of orientation to the flow was 30 degrees and that the best pitch of the screws (distance between the turns) was 60% of the diameter. Jupiter started with a 36″ diameter plastic screw turbine and then moved to a 42″ plastic screw turbine. The tests with both these units were conducted with monitors from the Canadian Hydrokinetic Turbine Test Center operating out of the University of Manitoba and two reports were written. It was found that the power coefficient of this helical turbine was considerably higher than any other turbine they have tested. These reports, along with the two reports from the University of Calgary are available on request.

​Jupiter’s conceptual design on the right was for shallow water applications.

The turbines have a 36″ diameter.

Delta Unit Successfully Deployed – Q2,2014

Test results were recorded by the Canadian Hydrokinetic Turbine Test Center (CHTTC) which is supported by the University of Manitoba.

Phase 3 – Commercialization​

The unit show on the home page is the most effective orientation of all our testing and the game plan laid out on the Home Page is what we will be following.
