Thank you. That's a very insightful question.
The answer is yes. In fact, we've looked at using biomass in our coal-fired plants in Alberta. Clearly, the biggest factor is the transportation cost and logistics of moving biomass. We're talking about huge volumes. To give you an example, one coal-fired power plant might look at a volume of 200 or 250 truckloads of biomass to supply approximately 10% to 15% of the daily energy requirements to a typical coal-fired unit. So transportation is extremely important.
You're correct, we haven't looked at water transportation. I believe that if one could solve that problem, with water as a transportation vehicle, it would go a long way towards overcoming some of the economic barriers that face coal-firing today.
