It would cost about $8,000 a kilowatt. We did a study at the Biogas Association, an Ontario association of biogas owners, which surveyed a number of existing biogas plants. A farmer would need a certain number of cattle, probably about 500 head, to make it viable. You would use the money generated through electricity production from the manure process through the digester and bring in some off-farm organics, but it's very difficult in Ontario to make those numbers work.
