I can tell you that, as we said, the power costs for the northern communities can be anywhere from 25¢ to $2. Most of them are in the 50¢ to 80¢ range because the $2 reflects the fly-in type of fuel.
We've done our modelling, and we can make this work, we think, at 20¢ per kilowatt hour. Essentially, the first prototype that we would develop is going to be about $200 million, we figure. Then, if we can develop installations for $100 million on a 25-megawatt system, the model works. It doesn't work for each installation if our insurance costs are $1 million and higher. We can keep those costs in line if our insurance costs are less than that.
