The obvious use of the GB propulsion system is a drone with 4 units that can be used for fast transport of goods over a long distance. The EDFs create a horizontal thrust twice the weight of the vehicle. Therefore our drone can easily reach velocity over 300 km/h.
It takes off vertically and can instantly switch to horizontal flight,
wherein it stays all the time.
Imagine that after an accident the rescue vehicle arrives in less than a minute and lands on the sidewalk. So there is no problem with commuting and with patient transport to the hospital. Imagine that a drone at the speed of 300 km/h transports blood or organs and lands next to the operating room.
