The research we're doing at the Canadian Centre for Housing Technology is part of that. When we put in a fuel cell, the first fuel cell to be put in a residential building, the idea was to integrate it with other sources within the house to supply energy. The next step, which is the thinking now and is not in place, is to try to put an integrated energy system in a house, working with NRCan and others in putting that together.
Our institute in Vancouver is as well trying to think of fuel cells in an integrated fashion. For example, there are some fuel cells used in Japan as part of the energy system for a house. The company in Vancouver is selling that in Japan.
It is starting to show up. The institute will look at how you can integrate that particular source, along with other energy systems, so that it comes with controls to connect to the grid, area controls, and instrumentation areas.
