Could your breath be turned into biofuel? What a strange question that is, and one you’d assume should be answered with a resounding NO! But in fact, the Liverpool John Lennon Airport is testing out a new technology expected to do simply that: recycle passengers’ breath into biofuel. The device is called the Eco-Box and will capture CO2 from the air that’s exhaled by passengers and turn it into fuel to be used by the airport’s diesel vehicles and heating system. It’s expected that 24,000 gallons of fuel will be collected in the test run, plus heat and hot water for the airport. And if the test run goes smoothly, their next goal is 289,000 gallons of fuel, which will translate into 800 gallons of biofuel each day. Sometimes the craziest ideas turn out to be the most amazing inventions!
