Reducing fuel consumption and emissions is a goal even in the world of espionage. AeroVironment Inc. is designing an unmanned aircraft that runs on liquid hydrogen-power. Its Global Observer will fly at an altitude of 65,000 ft for up to seven days. The high altitude, long endurance aircraft is being built for the U.S. Special Operations Command, which teamed up with other military to provide $57 million for three aircraft. AeroVironment recently picked Rockwell Collins to design the drone's navigation system. Rockwell's Athena 411 incorporates solid-state gyros and accelerometers, magnetometer, a GPS receiver and air data sensors into a single small unit.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
