A solar-powered airplane finished crossing the United States on Saturday, landing in New York City after flying over the Statue of Liberty during its historic bid to circle the globe, the project team said. The spindly, single-seat experimental aircraft, dubbed Solar Impulse 2, arrived at New York's John F. Kennedy International Airport at about 4 a.m. local time after it took off about five hours beforehand at Lehigh Valley International Airport in Pennsylvania, the team reported on the airplane's website. Such a pleasure to land in New York! For the 14th time we celebrate sustainability," said the project's co-founder Andre Borschberg on Twitter after flying over the city and the Statue of Liberty during the 14th leg of the trip around the globe. The Swiss team flying the aircraft in a campaign to build support for clean energy technologies hopes eventually to complete its circumnavigation in Abu Dhabi, where the journey began in March 2015.

Motion capture works by placing cameras with infrared LEDs around an area containing an object, person or animal wearing reflective markers. The light hits the reflective markers and thus the marker's position is reflected back and recorded.he group at Bradford has attached markers to a horse and captured a range of motion. This biomechanical understanding can then be embedded into animation software.
This significantly reduces the time required to build an animation, and delivers more realistic results. It is also becoming cheaper, as new types of camera are brought to the market. Abson highlighted the cost benefits for film makers.Image copyrightBradford UniversityImage captionThe motion of a cat was tracked using the same method
"In Avatar six years ago, they placed one or two markers on the animal to track its position. If you're paying for the motion capture system you might as well fully utilise it, rather than tracking the position and then getting an animator to do all the work," he said.
The technique could also be used to build more realistic animations of extinct animals and mythical creatures like dragons and flying horses. Mr Abson is already working with British, American and Russian film studios, and the gaming company Electronic Arts. The technique is also proving useful in veterinary science as a teaching aid, which is how the work originated.
Through collection and measurement of data, rather than observation and experience, more accurate diagnoses of animal injuries such as horse lameness can be made.
