Why would you use batteries? Fuel gets lighter as you use it, and the density is already there. Automate maintenance so you can use turbines.

- ianpurton 10y agoMy guess would be electric might be simpler and easier to maintain and with electric you can charge at home.
- mtgx 10y agoMaintaining EVs is cheaper and easier than fuel-based vehicles.
- arca_vorago 10y agoI've thought the same thing, perhaps efficiencies for generating electricity for fuel engines are too low currently? Anyone have any stats?
- soundwave106 10y agoNot my area of expertise here, but since quadcopters are all about torque, I speculate that electric motors (with their flat-ish torque curve) are much easier to design for?
- ChuckMcM 10y agomass per kilowatt hour. That is the magic number. While a gas turbine can be slightly over 52% efficient it weighs a lot. You can plot weight over kilowatt hours, which is useful since at small numbers of kilowatt hours batteries are a huge win, and then at some point you get a cross over where the fact that fuel is more energy dense it has compensated for the weight of the turbine and generator infrastructure.
