The entrepreneurs turning carbon dioxide into fuels
Want CO2 – use the exhaust from a gas-fired power plant. Very little in terms of other emissions – mostly CO2 and Nitrogen. Capturing CO2 directly from the air is incredibly inefficient and costly. It also consumes a lot of energy. Take it from the exhaust – this will prevent it from going into the air and make nice veggies and flowers with it. But why saving money if taxpayers can be bled white.
