Call For Submissions! 2008 Canadian Invention Competition

A C$10,000 feasibility study, C$50,000 worth of design and construction on your prototype, and up to C$10,000 liability protection will go to the winner of the second annual Canadian Invention Competition, co-sponsored by Canadian Business Magazine and Nytric, a Canadian innovation engineering and consulting company.

Last year's invention contest winner, Ortwin Groh from Chilliwack, B.C., invented a trailer-hitch alignment system that he had been working on for 14 years. Because of the support he received from Nytric, he was able to produce a production-ready prototype that would not infringe on other trailer hitches and that utilized affordable materials. Now Groh is in discussions for an exclusive license with a potential North American manufacturer and distributor.

An interesting side-note to last year's invention competition is that there were three inventions which were of strong interest to the judges. Nytric felt that it could have developed all of them successfully, but two of the three inventors did not have the umph or the dedication to see their inventions through to market. Mr. Groh, on the other hand was totally committed to his invention, and he now spends six hours a day working on it. Oh, that six hours a day? It's in addition to his full-time job.

So commitment is one qualification, living in Canada (except Quebec) is another, and the third... is a super invention! Find the application here; applications are due by May 2, 2008. And good luck!

invention competition

submited an idea to Michael of bg-consulting -group and they didn't even give me a 'this suckss' reply. I know its too late for the current competition, but next year will do. If it wins anything please make the check out to PurePower. James Tracy needs some funding.

I punched the ends out pop cans and using a 2x3 steel stud to align them glued them together with silicone to form tubes about 7 ft long.  After gluing up over 600 cans, I fitted the tubes into a box about 2 ft square x 8 ft (made from  1 in extruded foam)  A second piece of 1 inch stock with holes drilled through it to accommodate the tubes was installed about 6 in. in within each end of the box to hold the tubes in position and form a chamber at each end of the box connected to the passage through the tubes.  The ends of the box were then closed off with the 1 inch foam and 4 inch holes were drilled to accommodate  2 vent pipes at each end in places that created one path for the air through the tubes and another path on the outside of the tubes.

With equal air flow through this exchanger going in and out, the cold air coming in at -20 deg C. was  +19 deg C. as it left the exchanger and entered the room.

It was obviously pretty efficient, but every time I spoke to the Government research experts I was told that what I had was a flat plate exchanger, and they had tested everything on the market and a flat plate collector was doing really good if it managed 50% efficiency, so my numbers could not be right. " The air laminates and the layer near the exchanger rolls along the surface, and most of the air gets through without ever touching the exchange surface."

Now it gets interesting.  I knew my numbers were right, so I had a search, and they did not come up with much.  From the Patents selected as samples of the art I noticed that one word was missing from all these patents related to heat transfer.  The one word that does not show up is CONVECTION.

My exchanger was as efficient as it was because the air flowing through it was so slow that convection was taking place at the exchange surface.   Air within the unit could rise or fall as its temperature (density) changed.  The cold air came in at the bottom and did not leave the unit until it had risen to the top and the hot air entered at the top and was not directed to the outside until it had cooled. and fallen to the bottom.

The new and improved heat exchanger.   Imagine a room divided into two equal halves by a floor to ceiling curtain which would be the exchange surface. This could be metal or even a sheet of mylar film.  The warm stale air is blown into one side  at a high point in that half of the room and the exhaust from that half of the room to the outside is at the bottom of the room.  The volume of air passing through this area has to be small relative to the size of the exchange surface so that convection can occur at the exchange surface, and allow the air to flow down the cool exchange surface.  On the other side of the room the fresh cold air is moved into the bottom of that half of the room with a blower and allowed to choose its own speed up the exchange surface as it warms up.

Warm air is being drawn into the building from the warmest part of the intake side and exhaust air is being drawn off the coldest part of the exhaust side.

This is an exchanger that could probably handle clothes dryer and even stove exhaust in an apt.  It will more than likely not freeze up.  The janitor would have to sweep it out once in a while.

bg-consulting-group is the only organization that I have made aware of this 'invention'  Several individuals have seen my efforts but you are the only people who know as much as I do about the application of convection in a heat exchanger.
