 Fuel cell is actually a very old device. It was invented back in the late 1800s and it turns hydrogen into electricity. 0.99999% reliable. So when the grid goes down, the fuel cell keeps working. As long as you supply with hydrogen, it's just going to keep working and it works quiet. It's a smaller footprint and you can recycle the heat for the building or for the cooling. It was late at night and we were going about 70 miles an hour down the freeway. I rolled down my window, pulled up to the car next to me and asked him a question in a normal speaking tone of voice. They replied to me in a normal tone of voice because these cars make no sound. The petroleum free so it does reduce our petroleum dependency completely. A lot of makers often refer to a fuel cell vehicle as a no compromises vehicle because you're getting the performance and ease of an electric car with the range and the convenience of taking gasoline. I'm using them for a lot of mission critical missions right now. I'm using them for the unmanned vehicles that go into water on land. Cisco, a huge company based in Houston. I'm using a forklifts from Al Sier and Amanda Brewery. California is using it. They actually make their own hydrogen too from the Brewery waste. They can use that biomass and create hydrogen out of it. They're running their facility with a fuel cell and they said fuel cells enhance every other energy option. They're a cell there, every clean energy option is out there. They're scalable, they make wind better, they make solar better and they can help batteries. You can think of them as the medical process or the servers making the whole clean energy portfolio work better. We say the fuel cells are transforming the energy of the age. They are also integral to the whole clean energy portfolio and make it all better. Because this industry is going to be here. The choice is it's going to be homegrown here or is it going to Asia? In Europe.
