 I have been mainly focusing mostly on the wind energy because in Wisconsin it is very important. Yes, wind energy has been existing in many, many years. First of the wind turbine has been already discovered, 200 BC. And so technology itself is not new. It has been carried throughout the entire history. However, because of the shortage of the energy and fuels, we have been reviving this kind of old-fashioned energies. If you look at eagles, everything has tilt at the toward the end, which is called winglet. And I have been doing this for airplanes, which already have wings, which controls the turbines. If you look at other kinds of animals, such as whales and other types of animals, which has a very interesting type of wing, which is called a tabular type. I have been working on this with a tablet. This kind of shape comes from a whale, is really controlling the turbines and making the power more and more from an aerodynamic point of view. I have been aggressively working with wind energies since 2008, and they have been sponsoring a lot. So that we could establish a very good wind turbine, wind tunnel system here. And this wind tunnel is one of the biggest ones, which we got a lot of donations from wind energies. I am Rio Amano. I am a Milwaukee engineer.
