We've looked at power generation in the past. We had a project that actually ran a very large engine in Manitoba doing power generation exploration, looking at the possibilities of running our technology. It was very successful. It was at a time when there were many energy people who thought North America was running out of natural gas, so we shut down that project at the time.
Since that time, there are businesses throughout North America and around the world, Australia being a case in point, where distributed energy, using liquefied natural gas or natural gas from a pipeline, has become quite popular. It all depends, of course, on whether you're going to generate electricity using natural gas on a distributed energy level, for example, using a large internal combustion engine generating electricity. What is your alternative cost of electricity? From what we understand, in certain jurisdictions where electricity is very costly, such as where it's being generated by diesel power plants, it's a very good economic decision to switch to natural gas. However, when you're going from the grid, which might be quite cost-competitive, to an alternative fuel power generation application, it may not be worthwhile.
That being said, because of the growth of distributed energy in mining and other areas and in remote areas, companies like Caterpillar, Cummins, MTU, and others have come up with some very sound technology for that application, so we're not about to compete with them at this time on that. They have some great engines. There are mines in Australia where they truck out LNG 1,000 kilometres to the mine site, and then the LNG is used to power natural gas generator engines.
