Solar Powered Aircraft


An aircraft that can fly to any location on Earth;
without need of any airport to operate from.
It needs no runway; landing and taking off vertically from unprepared fields, from icefields, desert sands, heavy shrublands, from lakes, rivers; ....even from the surface of the ocean.
It has no range limitations.
It can fly over oceans, mountains, continents, or around the world.
It is slower than commercial jets; but faster than trucks, trains, or marine ships.
It can carry hundreds of passengers, or hundreds of tons of cargos.

No Blimps. No zeppelins. Only RIGID SHELLED AIRSHIPS

Large airships have the expanse of hull needed to carry huge arrays of solar cells; airplanes do not. Hull surface areas are large enough to allow less costly solar cells with lower efficiencies to be used with great effect.

The ideal is to deposit amorphous thin film photovoltaics (solar cells) onto very thin metal substrate materials such as aluminum, titanium, or stainless steel. These SUBSTRATES ARE INCORPORATED INTO THE STRUCTURAL ELEMENTS OF THE HULL itself; serving double duty.

Solar generated electricity is fed directly to electric motors driving the airships' propellors.To reduce the weight of the motors, advanced electric motors that substitute superconducting magnets in place of traditional copper wire are used. Excess electricity generated during daylight operations is used to divide water by electrolisis into oxygen and hydrogen; which is stored for use in fuel cells for flight during night or overcast sky conditions.Water exhaust produced by the fuel cells, and water condensed from ambiant air during flight, is conserved as ballast to be cast off or saved as needed to adjust or maintain the airships' bouyancy. BIO-DIESEL powered electric generators are used as a back-up system to the solar cells and fuel cells.

The nice thing about airships is....they float in the air.

Which means that they do not need to rely upon thrust to fly. Which means that they do not need complex, expensive engines to produce thrust. Which means that they do not need the special aviation fuels used by airplanes. Which means that airships can save the world!
The giant zeppelins of the 1930s' used simple, reliable diesel engines. If it's been done successfully in the past, why not now? Except, change the diesel fuel to....BIO-DIESEL. just saved the world; or, at least, made a huge impact. Consider, you can now provide air transport to ANY market, using fuels that can be produced in ANY locale, regardless of the costs or availability of fossil fuels.

During flight using solar power only, there are ZERO carbon emmisions.

this is really interesting. airships can be a good source of transportation. im excited to see one someday.

What a great example of "thinking outside the box!" I hope your company is successful soon because I'd really love a ride on a Turtle Air Ship

Thank you CorgiFan.

It's a long hard struggle to get our project moving. We're currently working with European Commisions' FP7 Clean Sky Inititive to secure funding. A small chance; but a chance.
Recent over Half Billion dollar investments made by militaries for airships will help.
In any case, we'll persevere! You'll be able to ride a Turtle Airship one day, certain!
