About Bubble Action Pumps Ltd. (BAP)

BAP is a small but innovative Canadian company with a revolutionary system of circulating the working fluid in solar water heating systems[WikiPedia.org] by means of a bubble pump. The system is revolutionary because the pump which is always required in frost-prone climates uses no electricity, has no moving parts, is self-controlling and yet moves the heated working fluid from the collector panels [WikiPedia.org] on the roof to the heat exchanger [WikiPedia.org] at the storage tank [WikiPedia.org] below.

Wilfred Sorensen [Google Search] invented the bubble pump [renewableenergy.wikia.com] in 1981 when he was practicing architecture in Kingston, Ontario [Google Maps]. Research was carried out at Queen's University [QueensU.ca] Solar Calorimetry Lab with funding from the National Research Council [nrc-cnrc.gc.ca] of Canada. In 1978 unknown to Sorensen the US Department of Energy [Energy.gov] had commissioned the Franklin Research Institute to put together a team of experts to conceive ways to make pumping for solar water heating systems electric-free and self-controlling. Out of 21 possible solutions the one they gave the best hope for was the bubble pump.

BAP was incorporated in 1982 to carry on research, development and eventually to license or manufacture and market the pump. An early license agreement came to an end with the cessation of subsidies first in the US and then in Canada. Then the low cost of energy due to the recession of the 1990s devastated the solar water heating industry. BAP did manage to sell a few pumps mainly in the US in order to get feedback from do-it-yourself customers. Getting into production, however, was out of the question due to low energy costs and subsidies to the fossil fuel and nuclear industries.

Today, with high energy costs [GlobalSecurity.org] and the certainty of global warming [WikiPedia.org], the market for solar water heating has much improved. Having weathered the bad times and continued with research BAP is ready to expand production and share its technology with the world. There are many opportunities for those who are able to discard the old technology for the new. People around the world want hot water. When they come to know about electric free pumping, they will demand it. Only a tiny percentage of buildings [EnvironmentCalifornia.org] in the world have solar water heating systems [SmartEnergyLiving.org]. We invite everyone to help us change the proportions so that only a tiny percentage of buildings do not have one.
