We did work a long time ago, about 20 years ago, on horizontal wind turbines. At that time, we called them “egg beaters”. You may have seen the pictures. The work was done at NRC, and it was tested at the wind tunnels as well, but it didn't actually take off. I guess the Europeans have somehow taken hold of the wind energy file or wind energy production. Most of the wind turbines being used now come from places like Denmark and Holland, the Netherlands.
There are small wind turbines, as I mentioned. A company makes small ones that you can put on top of a house to run a heat exchanger, a small hot-water system, or something like that. This is a new development. It can be integrated with energy systems for a single unit or a small building, where you can combine wind, small hydro near a stream, or fuel cells in the future. It will become an integrated system that you won't supply through only one item. You can supply electricity and heat from difference sources and integrate that within a building.
