 Solar thermal has a role to play in the grid, as we gradually move towards a system where the fossil fuels are having a smaller and smaller role. So our dish is 500 square metres. It focuses energy into a very small focal point. At the peak of that focal point, we have 14,000 suns distributed over an area of about 500 millilitres. We get about an average concentration ratio of 2,200 suns. The most exciting thing about this project is that we managed to increase the efficiency of a receiver from 93.6% up to 97%. That's what we believe to be the world's most efficient solar receiver. It would produce enough electricity to power a street of houses. So solar thermal has the advantage that it can provide storage. It has storage integrated with the technology. The way we store energy for this kind of system is in the form of molten salts. These heat up to 560 degrees or so, and then when you want the heat, you can produce steam and run it through a turbine. And so you can produce power whenever you need it. It's a new and exciting industry, and I think it's got a huge future.
