From cleantechnica:

“A Spanish company called Turtle Airships is working on plans to build a luxurious solar-powered blimp which can take passengers from New York to Paris.

Perhaps the only thing cooler than being powered by lightweight photovoltaic cells, this airship is also designed to rest on land or water.

The first blimp prototype will be propelled in two nontraditional ways. The outside of the ship will be covered with Cadmium-Indium-Germanium (CIG) photovoltaic cells, picked for their their light weight. The cells should generate enough power to move the blimp at around 40 mph in average conditions, or at around 70 horsepower. Meanwhile, a diesel drivetrain will generate the rest of the power, and ideally the designers will look to an adapted hybrid electric model for that. And because blimps fly at low altitudes, they don’t have to deal with problems that plague diesel engines at elevations over 30,000 ft.

The only thing currently keeping this visionary project from flying is…”
