Diesel engines power our world but release toxic soot and gases that harm our lungs and the planet. To fix this, scientists found a simple "hack": mixing a little water into diesel fuel. This creates tiny "micro-explosions" that help the fuel burn cleaner and more efficiently. The benefit is huge—it cuts harmful pollution by up to 68% and works in existing engines without any expensive repairs. This gives us a cheaper, faster way to get cleaner air in our cities and farms.
