There’s a new aircraft in the skies that could be changing the way we fly. It’s from a company called Solar Impulse and it doesn’t fly on traditional jet fuel or other combustible material. It’s flying on solar power. The aircraft itself has a wingspan of of just over 200 feet. It contains four electric motors which give it 10 horsepower which is enough to fly cross-country. The top speed of this aircraft is a speedy 50 mph.
While not particularly speedy, the photovoltaic panels on the HB-SIA were built by the transcontinental solar flight record holder Eric Raymond.
Solar Impulse has been flying the HB-SIA for three years and even had a flight lasting longer than 26 hours. The pilot was able to gain altitude and charge batteries during the day while still flying and slowly descending during the evening.
Solar Impulse’s ultimate goal is to fly around the globe in 2015. The team expects to begin construction on the larger plan this fall. Currently, a team in California and engineers in Switzerland are completing the design on the airplane.
Where will solar take us next? Who can tell but solar powered aircraft have many potential advantages. We could find low cost ways of shipping products across the country, replacements for surveillance drones and more.
