In aerospace, for example, we are always on top of that, because we are practically the institution of choice for aerospace companies to work with. We work, for example, to certify the new engines. So we have to anticipate the technology to be able to actually meet the demands of new engines for higher efficiency, lower noise, and lower emissions, when these new engines come out. So we have to anticipate what we need to do.
For the work on new fuels and gas turbines that I mentioned, now the tendency—and there's some scattered work on this around the world—is to find other fuels for stationary gas turbine engines generating electricity. If you do that, it means you need to take a very close look at standards for those: at what the turbines will need, at the blades, at the new materials and coating on these materials, and read the emissions coming out of these fuels. So this is what we anticipate, and we're now building up the project in the environmental lab to be able to meet those.
They haven't yet come to us, actually. We know of them, and when they come, we'll be ready.
