Bertrand Piccard and André Borschberg succeeded in their crazy dream of achieving the first ever Round-The-World Solar Flight.

Solar Impulse 2 landed in Abu Dhabi more than a year after its initial take off, marking the end of an epic 25,000-mile (40,000-kilometer) journey.

The plane made 16 stops, including in India, China, the U.S., Italy, Egypt and the United Arab Emirates -- where it first took off.

The Swiss-engineered single-seater aircraft is powered by 17,248 solar cells and runs on battery power at night. Its average airspeed was 46 mph, though that increased during the day when the sun's rays were strongest.

It took 70 hours for the plane to cross the Atlantic and 118 hours across the Pacific.

On Sunday, Piccard took off from Cairo in Egypt to complete the last leg of the journey, landing 48 hours and 37 minutes later in Abu Dhabi at 2:05 a.m. CEST on Tuesday.

Their zero-emission electric and solar airplane, capable of flying day and night without fuel –

By landing back in Abu Dhabi after a total of 21 days of flight travelled in a 17-leg journey, Si2 has proven that clean technologies can achieve the impossible.




My question is what happens to our crude oil when Solar car too is launch

Been expecting this.

The rest of the world is fast advancing and leaving Nigeria in the dust.
Its a good step forward for mankind.
Imagine what follow-up technologies could turn up with and what that could do for interstellar travels?
Propulsion systems that don't run on carbon fuels, wow?
