    Yeah, that’s what’s shown in the video, basically a large six propeller drone. The big issues seem to be safety, flight time (battery lasts 20-30 minutes), and air space regulation.

    Personally, I don’t think drones are there yet and may never be. The range is probably always going to be limited due to energy density and at that point mass transit (like trains) will always be the better/safer option. Even if you can solve the energy issue I think you still run into safety issues including high wind scenarios.

      You can do it now but it’s expensive. You could also just put a really big battery on it and make it fly further but that makes it expensive and makes the propellers big.

      As the propellers get bigger they cannot spin as fast because the radial velocity becomes massive and the blades cannot hold the force. The ideal way to build a drone like this is to actually have many smaller electric fans with two turbines running generators that power them. It’s safe and performant and more durable.

      I think a cooler idea is more bike like platforms, something around 750 ibs, that can fly and hover. Maybe with articulating sections like a Gundam or something. Covers the face and blocks the wind a bit for comfort. That would be cool and maybe more like new car priced.

        I wasn’t saying it couldn’t be done, I was saying drones as vehicles doesn’t seem viable (economically or for safety reasons).

        Also, when you put in bigger batteries you increase the weight, thus increasing the amount of power you need to fly the drone. If these ventures say their drones get 20-30 minutes of flight I would assume that’s got to be around the current sweet spot.

        You’re idea for making it more bike-like might be able to help with flight time (if drag doesn’t become a larger problem), but I don’t think commercially anyone is going to want to fly unprotected from wind and the elements.
