A bright idea: Solar plane is crossing the USA

It's one flight down and four more to go for Solar Impulse, the completely solar airplane that's soaring its way across the USA. Solar Impulse flew from San Francisco to Phoenix on May 3, taking a shade over 18 hours to complete the trip. Over the next couple months, it will fly legs to Dallas, St. Louis, Washington D.C. and New York City with the New York trip scheduled to conclude in early July.

For the stat freaks, the solar plane averaged a speed of 40 miles an hour at an average altitude of 10,000 feet. It soared to a maximum altitude of 21,000 feet over the 650 mile trip. And yes, it took off and landed in the dark.

More information about the Solar Impulse project can be found at its website here and to follow its progress flying across the country.

So how does a solar airplane work exactly?

Made of carbon fiber, the plane has the wingspan of a Boeing 747 (208 feet) and the weight of a small car (3,527 lbs). It is the result of seven years of intense work by a team of about 80 people and 100 partners and advisors. The 12,000 solar cells built into the wing provide four 10 horsepower electric motors with renewable energy. By day the solar cells recharge lithium batteries which allow the plane to fly at night. Swiss pioneers Bertrand Piccard (chairman) and André Borschberg (CEO) are the founders, pilots and the driving forces behind Solar Impulse.

The plane made its first night flight in 2010 and has a record endurance flight of 26 hours, 10 minutes, 19 seconds.

Solar Impulse wants to inspire and motivate as many people as possible throughout its journey across America. “We want to show that with clean technologies, a passionate team and a fa-reaching pioneering vision one can achieve the impossible.” said Piccard, adding “If we all challenged certitudes by driving change and being pioneers in our everyday lives, we can create innovative solutions for society’s biggest challenges.”

Here's some more nitty gritty about the plane's specs and future:
• The electricity produced by the solar panels is about the same as needed to run a scooter for 24 hours.
• The light plane is sensitive to turbulence. Winds cannot exceed 11.5 miles per hour at take off and crosswinds at takeoff can be no more than 4.6 miles per hour.
* A second plane is now being constructed.
* Solar Impluse has a goal of making an around-the-world trip in 2015, with 2-3 day flights over continents and 4-6 day legs over oceans.

And just to prove it actually flies, here's video shot in the San Francisco skies before Solar Impulse began its USA journey.

To MAKE FUTURE EARTH Solar panels are installed at every home.
one of the most important step of USA government is the installation of solar panels at WHITE HOUSE roofs.
