The aircraft, which had to undergo a refit in Hawaii after the epic leg from Japan wrecked its batteries, reportedly performed flawlessly on the trip, which ended with a dramatic entrance over the Golden Gate Bridge on the way to Mountain View just south of San Francisco. "WOW. A normal day as an explorer," the organization tweeted as it sent out an iconic photo of the aircraft over the bridge shot from a chase aircraft with founder Bertrand Piccard at the controls. "It's a new era. It's not science fiction. It's today," Piccard told CNN from California after landing. "It exists and clean technologies can do the impossible." A big window of benign weather, rare for the North Pacific, helped the effort and the landing was under clear skies. The Mountain View landing was a diversion from the scheduled U.S. arrival point of Phoenix and it's not clear what route the aircraft will take as it crosses the U.S. It has a major challenge ahead with a northern Atlantic crossing on its way to finishing the circumnavigation in Abu Dhabi. Video: https://youtu.be/wQCOfuwG6ss. It's a toy. One seat flies at 30 odd knots and cooks batteries in a -c environment And is accompanied by an inflatable hangar, ground crew in commercial airliners Personally, I wouldn't characterize it as a toy, but more like a proof of concept vehicle, to demonstrate the feasibility of harvesting the sun's energy to potentially provide clean, sustainable transportation. At any rate, if Solar Impulse II successfully flies around the world solely powered by energy from the sun, I'd equate that with Lindbergh's solo Atlantic feat, at least. At last, electric power appears to have planted its banner solidly in the fertile soil of transportation. And, hydrogen fuel makes it a clean, feasible alternative to gasoline, that can be generated by solar powered electrolysis of water (on the ground) without the pollution of petrochemical extraction and emissions. Current photovoltaic cell's limited efficiency preclude their use to power heaver than air aircraft in a practical way, but for lighter than air aircraft, they may be quiet well suited, as they won't have to provide the power to support the weight of the aircraft, only propel it. It's about time superior technology pushed aside the vested interests, and be recognized for its true benefits. Perhaps there's hope the 21st century may initiate an era that transcends politics, profiteers, and plutocrats, recognizes the limitations of a closed system, and offers long term, sustainable solutions. We can hope ... |
