Are there any small methane to electricity generators which I can install into quadcopters?<p>I am annoyed with small battery life of quadcopters, want to make quadcopter which can lift ~10-15kgs and want to get power from methane.<p>Any ideas or suggestions related to making battery life of quadcopter/drones live longer?
I saw a hydrogen one the other day.
One problem is both methane and hydrogen are low density gasses and require pressure vessels = linits load.
You could fuel with liquid methane or Hydrogen, as a small dewar flask of superinsulated pod would be light in weight, but would have limited shelf life.
Catalytic break down of alcohol to Hydrogen might work?
