I wonder if the development of thinner, flexible solar panels and batteries would make a lighter than air UAV a better choice for eternal flight. That way it only needs to power rotors for positioning instead of maintaining flight.
- jselfridge 8y agoDARPA already looked at that through ISIS. The problem is the massive volume of gas within the airship. Even the lightest winds require a substantial amount of power to travel or station-keep. Google is using weather balloons, but they don't have any active controls, so they drift aimlessly away from the equator, and then need to be manually picked up after about a month.
