It's an opportunity to use the systems that have been developed through technology and have them in rural and remote communities where they are highly dependent on diesel generators. The technical problem, from what I understand—and I'm not an expert in this area—is getting rid of the tar.
We have to do some more work before that can be taken much further. You can use the gas that's generated to heat water, but you can't use it for electricity. That is a technology glitch on which we need more work.
