Amazing Sky Lifter Powered by Solar Power and Biodiesel.Solar-powered SkyLifter carries 150 tons of anything to anywhereWhile hoping to go beyond the modern day helicopters limited load-bearing capacity, Australian firmSkyLifter is busy evolving a solar-powered airship for carrying up to 150-ton loads more than 1,200 miles. Just the perfect machine to support disaster relief operations, the solar blimp could ship payloads of equipment, freight, pre-constructed buildings and other loads at a speed of 45 knots (50 mph).Where the vehicles disc-like shape offers immunity against different wind conditions, the specially designed Voith-Schneider propellers (measuring 500ft across) and strategically placed cockpit help the vehicle in keeping steady. Aside from using it for disaster relief, the developers hope to use the vehicle as luxury airborne cruise ships.
