Solar airship is most efficient way to fly, ever
How can you carry huge amounts of cargo thousands of miles with no fuel and no infrastructure? By combining an airship with an airplane, of course. The resulting wing-shaped blimp requires less helium than a conventional dirigible, but has a shorter takeoff than an airplane. Hybrid Air Vehicles has been proposing this for years, but upstart Solar Ship has taken the additional step of designing a craft that can be powered entirely by the sun.
It's intended to service remote areas without roads, where fuel and even runways aren't available. It comes in three sizes. Caracal class Solar Ships are for carrying instrumentation and maybe a passenger or two, Chui models can carry 1,000 kg (2,204 lbs.) of cargo, and behemoth Nanuq models are depicted carrying an 18-wheeler.
