Aerospace firm successfully tests solar-powered aircraft

A test pilot successfully flew a solar-powered prototype aircraft on Friday for a company that envisions manufacturing a fleet of drones to provide aerial internet service for an estimated 4 billion people worldwide.

The test flight by Luminati Aerospace LLC took place at a former Northrop Grumman defense plant on eastern Long Island that once made military aircraft. Speakers at a ceremony before the flight recalled that Charles Lindberg took off for his historic 1927 solo flight to Paris from an air strip in nearby Nassau County, and others noted that the spacecraft that landed men on the moon was built in the Long Island suburbs east of New York City.

India vows to cut carbon intensity in Paris pledge

India's long-awaited pledge for a global climate pact shows how the world's No. 3 carbon polluter is making significant efforts to rein in the growth of emissions linked to its fast-surging demands for energy, analysts said Friday.

India vowed to reduce its emissions intensity by 33-35 percent by 2030 from 2005 levels, primarily by boosting the share of electricity generated by sources other than fossil fuels such as coal and gas to 40 percent.
