According to Wired, scientists at Oxford University have reverse engineered jet fuel from carbon dioxide. The breakthrough has yet to be replicated outside of the lab and would need to be dramatically scaled up in order to be viable for fueling air travel.A team at Oxford University in the United Kingdom has developed an experimental process using an iron-based chemical reaction that transforms C02 — a greenhouse gas in the exhaust of all gas-burning engines — into jet fuel.The study, published in Nature Communications, was conducted in a laboratory setting and must still be replicated at a larger scale in the real world.
