hydrogen more likely to take off in drones
skai is the limit
Could This Hydrogen-Powered Drone Be the Future of Transportation? Current battery technology would offer limited range in a human-scale electric vertical takeoff and landing vehicle, even when burdened with only the skinniest of rich people on their way to Montauk. And if you build a machine like that without batteries, that's called a helicopter and it's something that will definitely get you on the naughty list at your HOA when you land it in your backyard.
But Alaka'i Technologies in Hopkinton, Mass., thinks that the solution to this conundrum is hydrogen fuel cells, which allow use of electric motors but offer range and refueling speed more in line with your friendly neighborhood gas station. Its debut vehicle, the Skai, claims about 400 miles of range (or four hours of flight time), with capacity for five passengers or 1,000 pounds, whichever comes first.
