NASA engineers have completed tests on a device that opens the path for development of "all-electric" aircraft. Called the Electro-Hydrostatic Actuator, the device eliminates or minimizes airborne dependence on hydraulic, pneumatic, and mechanical systems. NASA tested the device on the left aileron of its F/A-18 Systems Research Aircraft without using the plane's central hydraulics. Taking its signals from the aircraft's flight-control computers, the device uses its electronics to trick aircraft computers into thinking a standard actuator is on board. Although the device contains a small amount of hydraulic fluid, it uses an electric motor to drive its pump. The force created moves the aileron. For many years, NASA, the Air Force, and the Navy have sought to eliminate heavy hydraulic systems in aircraft in favor of electrical "power-by-wire" systems for operating flight controls. The new device results from the Electrically Powered Actuation Design program of the Air Force.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
