Flowcopter is said to be creating the world’s first gas-fueled drone, with a flight range of hundreds of miles, potentially spanning hours. Current drones rely on battery power or electrical recharging. While the consensus is that battery technology is advancing rapidly, and will someday permit lightweight, long-range travel in drones and other vehicles, fossil fuels currently provide denser sources of energy with less weight and at lower cost. The reasons there are no gas-fueled quadcopters to date is their engines aren’t as precisely controllable as are electric motors. But Flowcopter feels it has overcome that.
