Solar Impulse Attempts Historic Flight Across the Pacific

Business

[Editor's note: Poor weather conditions are forcing Solar Impulse pilot André Borschberg to land in Nagoya, Japan at approximately 23:00 local time (14:00 GMT). Borschberg will wait for better weather conditions to continue his flight across the Pacific.]

Solar Impulse 2, the first solar airplane able to sustain flight at night with a pilot on board has been making its way around the world over the past few months. The plane took off today a little after 2 a.m. on Sunday in Nanjing, China. The flight from Nanjing to Honolulu, Hawaii is the seventh and longest leg of the first round-the-world solar flight. It will take an estimated six days to complete the roughly 5,000-mile journey. The first leg of the journey took place in early March, taking off from from Abu Dhabi in the United Arab Emirates and landing in the Omani capital, Muscat.

If the flight is successful, it will be the longest ever flight on solar power, both in terms of distance and time.

"Flying across oceans without fuel means taking renewable energy to the ultimate level," says the Solar Impulse team. The plane, which has been piloted by both André Borschberg and Bertrand Piccard, has a wingspan bigger than that of a Boeing 747 but it weights only one percent of that—about the weight of a large passenger car. Built into the wing are 17,000 solar cells that feed four electric motors and recharge lithium batteries for night flight.

The flight from Nanjing has been delayed for weeks due to weather conditions over the Pacific, which has made the build up to today's takeoff even more exciting. "A cold front over the ocean created 'a wall of clouds and thunderstorms stretching from Taiwan to above the east coast of Japan,'" the team told CNN. But when the team found a break in the weather, they decided to go for it. You can watch live coverage of the event here:

And you can even track the flight in real-time on their website. You can track the plane's altitude, its distance, its energy use, the air temperature and even what the pilot is doing at the current moment (piloting, interview, yoga, self-hypnosis, resting, eating or using the bathroom).

Shower shoes? Check. Extra-long sheets? Yep. Energy efficiency checklist? No worries — we've got you covered there. If you're one of the nation's 12.1 million full-time undergraduate college students, you no doubt have a lot to keep in mind as you head off to school. If you're reading this, climate change is probably one of them, and with one-third of students choosing to live on campus, dorm life can have a big impact on the health of our planet. In fact, the annual energy use of one typical dormitory room can generate as much greenhouse gas pollution as the tailpipe emissions of a car driven more than 156,000 miles.

Kokia drynarioides is a small but significant flowering tree endemic to Hawaii's dry forests. Native Hawaiians used its large, scarlet flowers to make lei. Its sap was used as dye for ropes and nets. Its bark was used medicinally to treat thrush.

From where I stand inside the South Dakota cornfield I was visiting with entomologist and former USDA scientist Jonathan Lundgren, all the human-inflicted traumas to Earth seem far away. It isn't just that the corn is as high as an elephant's eye — are people singing that song again? — but that the field burgeons and buzzes and chirps with all sorts of other life, too.

Indonesia's president has made permanent a temporary moratorium on forest-clearing permits for plantations and logging.

It's a policy the government says has proven effective in curtailing deforestation, but whose apparent gains have been criticized by environmental activists as mere "propaganda."
