Fast Co. Design's Mark Wilson brings to attention the drone ambulance by argodesign. The conceptual idea would see an overgrown one-person drone capable of bringing a single EMT to an accident, who would stabilise the patient, load him up and launch him to the nearest hospital.
Assuming you could build it, the drone’s benefits would be significant. A single pilot who would usually fly a single helicopter could manage a whole fleet of drone ambulances remotely, relying on autopilot through the skies, and taking over manual controls only during more complicated takeoffs and landings. There’s also the issue of price: Rolston believes an ultralight drone could be constructed in the million dollar range. That's several times more expensive than a wheeled ambulance, but still cheaper than a medical helicopter.
