Leave it to New Zealand to come up with the one, and only, instance where the combination of “alcohol” and “automobiles” is actually a good thing. There, local brewer DB Export has developed a new type of eco-friendly biofuel, the sin qua non for which is, yes, you guessed it—beer.

That’s why United Airlines came up with a brilliant idea: instead of soaking up so much energy, they would create a special biofuel made out of food waste, and use it to power their planes. The technology is in its finishing stages, and United is expected to be flying planes—fueled by animal fat!—sometime later this summer.

Can Biofuels Make Flying Clean and Cheap?

The first two transatlantic flights powered by biofuel blends made it safely to Paris. But blowing that much fuel to get somewhere is still a luxury.

Over the weekend, the first two transatlantic flights to be powered in part by biofuels made it safely to Paris. One, a business jet designed to ferry smaller (usually wealthy) groups, had a 50-50 blend of traditional jet fuel and biofuel in one of its engines; in the other plane, a larger, commercial jet, all four engines burned a blend that contained 15 percent biofuel.
