We use solar and wind power to make zero net carbon electrofuels

We remove CO2 and water from the air and use electricity from solar and wind power to turn them into zero net carbon electrofuels. These are gasoline, diesel, and jet fuels that work in existing cars, trucks and planes without requiring modification of their engines, and don't contribute to global warming because they don't add any new CO2 to the atmosphere. Each gallon of our electrofuels means a gallon of fossil oil left in the ground forever. Importantly, these fuels for the first time can compete with fossil fuels on price - our zero net carbon jet fuel has a price of one cent per gallon less than fossil jet fuel. American Airlines ordered 10 million gallons of this fuel and we will start shipping it next year.
