More Fuel-Efficient Jets Could Lead to Passenger Nirvana

Want more legroom, more direct flights, and less time stuck in holding patterns? It could be coming to airline passengers, but at a price: higher fares.

Regulators are moving along with targets intended to push commercial airlines to slash their emissions of carbon dioxide not by stuffing more of us onto the existing fleet, but by targeting the underlying issue of aircraft fuel efficiency. That will mean new, fuel-efficient airplanes, an upgrade that could come with creature comforts such as more legroom and state-of-the-art inflight entertainment.

But integrating new airplanes into existing fleets and upgrading technology will cost money, which may lead to higher fares, noted Vera Pardee, a San Francisco-based attorney with the Center for Biological Diversity, one of several environmental groups that are pushing the U.S. Environmental Protection Agency to regulate airline greenhouse gas emissions.

Can drones fly as well as Luke Skywalker

Next-generation drones may fly like Luke Skywalker zipping through the Endor forest on a speeder bike, suggests new research which focuses on how birds such as northern goshawks determine their maximum speed limit.

These birds race after prey through the forest canopy without smacking into tree trunks.

They avoid this fate by observing a theoretical speed limit, according to scientists at the Massachusetts Institute of Technology.

On Wednesday, Judy Wexler will pedal furiously, hoping to generate the force needed to lift a human-powered helicopter off the ground and win a $250,000 prize.

The biology student at the University of Maryland is a competitive cyclist with a desirable power-to-weight ratio and endurance, noted Brandon Bush, a graduate student in the university’s school of engineering and project team member.
