That's correct. It would require, first of all, a system that is sized to provide the same service at the home level, rather than having a big plant in a whole community development that services 5,000 people. So there is some research to be put into it.
With house systems and systems that would work on a home scale, most of the systems you have now are from other parts of the world—many from Europe—like solar hot water and on-demand water heaters that only come on when you actually need the water. Dual-flush toilets come from Australia. In Canada we have very little research on helping home-grown technology, to help us either develop our own technology based on the resource base we have or use technologies that come from other countries that we could adapt to Canada, to kind of leapfrog years and years of development.
For both, really the dollars do not exist, and it happens more by happenstance or by organizations like ours that promote it to designers and home builders and so on to use these products, rather than by a planned approach.
