Our current prototype is the size of a refrigerator. One of the cool things about our tech is that it can work well at small scale. We don't have to get to a billion dollar plant to get the economics right. We could make a system to fit in your garage and make fuel at home. This isn't our focus right now because we want to solve the problem of CO2 emissions from fuel, so need to scale as fast as possible. That's the commodity gasoline market.
