Of all the ways to travel, airplanes tend to be the fastest and the safest—as well as the most wasteful. For a long time, the industry has been criticized for producing excessive amounts of greenhouse gases. 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.
