How much we invest is a tough question. I think the issue is that if we have a mechanism that brings industry to the forefront with matching funds from the government, it will create more commercialization and you'll have money flowing back in. Innovation is a cycle. You need to start with research and go through the development and demonstration phase to commercialization, but that has to feed back.
How much more is an interesting question. You can look at different industries and say that we need this much more, we need that much more, but I think we need to be competitive on a world scale and I think, if I saw the correct numbers, that in terms of what governments invest, some of them are in the 1% of GDP category or in that neighbourhood.
My colleagues can better answer what we need to do to be competitive.
