Very cool drones, many of them new, being built or in development around the
world. These are some amazing aircraft, ranging from a 150-gram thing with a
single maple-leaf-like wing, up to some monsters with 175-foot wingspan that
carry a boatload of munitions and sensors. Power ranges from fuel-cell
electric power to a modified Ford truck engine that burns hydrogen:

The drones we should fear are those that are fueled by cheeseburgers,
tofu or sushi.
