The Roswell Test Flight Crew met with a number of firms whereas attending Interdrone in Las Vegas final week. In this episode, Patrick Sherman of the Roswell Flight Test Crew hears from Julian Hughes, the senior vice chairman for Intelligent Energy. He describes how the corporate has developed a small, light-weight hydrogen gas cell that may be mounted instead of a standard lithium-polymer battery on board a drone to radically prolong its flight time. Fuel cells are 3 times extra energy-dense than a standard drone battery. In the instance of a DJI Matrice 100, on show on the Intelligent Energy sales space at InterDrone, flight time will increase from 20 minutes to 90 minutes. Also, time to re-charge can be dramatically diminished. Once the hydrogen fuel on board the drone is exhausted, the strain cylinder will be re-filled in as little as two minutes, or changed with an one other, full cylinder. Hydrogen fuel is extensively accessible from industrial fuel suppliers.
