Engineers in London said this week that they’ve developed a new type of synthetic vehicle fuel that’s created out of water and thin air, literally by pulling carbon molecules out of the atmosphere and recycling them.

Speaking to a conference this week put on by the British Institution of Mechanical Engineers, researchers with Air Fuel Synthesis, Ltd. said they’ve successfully married a synthetic fuel production technique that dates back to World War II with modern atmospheric carbon capture and sequestration methods.

The resulting product, they said, works in all current vehicles, can be blended with conventional fuels, and just might be a game changer for human energy and the fight against climate change if it’s ever produced on a large enough scale.
