From Amazon to Zynga, many companies glean powerful business insights from slicing, sorting and analyzing data. But GE Chairman and CEO Jeff Immelt says it is the combination of big iron and big data that gives his company “a killer competitive advantage.”
Speaking yesterday at the Electrical Products Group Conference in Florida, an annual gathering of industrial executives, Wall Street analyst and investors, Immelt said that as a maker of both machines and software like Predix, GE’s “ability to combine the knowledge of the assets, the physics and the analytics,” gave an edge to its customers and to itself...Read More....
The U.S. Air Force announced Tuesday that SpaceX is now eligible to compete for launches of U.S. national security satellites, closing a tumultuous chapter in the U.S. rocket industry and ending the Pentagon’s sole reliance on United Launch Alliance to haul military payloads into orbit.
The Air Force’s certification of the Falcon 9 rocket gives SpaceX access to approximately one-third of the U.S. national security launch market forecast to be worth $70 billion through 2030, according to an estimate by the U.S. Government Accountability Office.
The Falcon 9 can lift the Air Force’s GPS navigation satellites, missile warning platforms, weather satellites, and some of the National Reconnaissance Office’s orbiting spy payloads. ..Read More....
From GPS to the Internet, many everyday technologies have military roots. The same is true for jet engines, especially those powering business jets.
For America, the jet age began the night of October 4th, 1941 with the arrival from England of a top-secret engine at a barren airport in Boston’s Back Bay. It was Sir Frank Whittle’s turbojet. Rebuilt by General Electric on the same grounds that now produce engines for the US Army’s Black Hawk and Apache helicopters, the IA engine was the first jet engine flown for the Allies during World War II...Read More....
In an effort to develop a safer and more responsive solution to ice and cold water emergencies, WISE Technology, based in Gilford, NH, has produced a unique amphibious vehicle specifically for ice and cold water situations. The AIR (Amphibious Ice Rescue) Responder is designed to handle any ice conditions. The patented hull allows the AIR Responder to move agilely from one surface to another whether its ice, broken ice, snow or open water. Whatever the surface conditions, the AIR Responder handles them with safety and certainty.

For every showing of “A Streetcar Named Desire” in a big city, there’s a street packed with traffic on the way to the theater. Let’s face it, large urban centers may have culture and opportunity on their side, but they come with irksome baggage like congestion, air pollution and the lack of parking.
That baggage is getting heavier. Although half of the world’s population already lives in cities, the U.N. estimates that the number will spill over the 50 percent mark and hit 5 billion by 2030.
The solutions to their growing pains will be complex. But one easy fix is already standing on every corner: the lamppost.
New “intelligent” LED streetlights combined with sensors generating oodles of data and cloud analytics could soon start delivering genuine street smarts and savings...Read More....
Most people might still consider the idea of using tides to generate electricity as outlandish as a trip to the moon. But starting this year, the concept is quickly becoming reality. “We went to the moon 46 years ago, and now we are using it to produce energy,” says Frederic Navarro, project director at GE Power Conversion in Belfort, France. “That’s because the moon’s gravity tugs on the ocean and produces predictable tides that run like clockwork, twice a day.”..Read More....
Over the last year, GE engineers have been testing the largest, most efficient and most powerful gas turbine in the world. It weighs as much as a Boeing 747 filled to the brim and, when paired with a steam turbine, can generate enough electricity to power the equivalent of 600,000 French homes. (Its exhaust would fill up the Goodyear blimp in about 10 seconds.)
This week, GE’s factory in Belfort, France, finished the first production unit built for the French utility Électricité de France (EDF)...Read More....

In this video, maxon engineer Jeff Randall explains a new right-angle gear drive … or RAD for short. Jeff also explains the difference between spiroid gearing (found in these new gearheads) and worm gearing (found in typical lower-cost designs). Among other things, spiroid gears have a much higher contact ratio than a comparable worm gear.
Shot at the maxon precision motors booth at the recent MD&M show in Anaheim, Calif., this video shows the spiroid gearing inside these gearheads … cut for maximum torque in minimum space. One version has a 22-mm front-mounting face and another has a 32-mm front face. Those sizes match the sizing of existing planetary gearheads so designers can swap or substitute the gearheads if needed.
The right-angle gear drive is a new gearhead that lets engineers build compact systems that deliver high torque. The gearbox housings are aluminum, which further boosts the torque-per-unit-mass. Other items of note:
• A back-drivable version has a low-ratio (4:1) is highly efficient • A non-back-drivable version has a higher speed ratio (30:1) has lower efficiency but doesn’t need a brake
Another feature is a spline interface for mounting to the motor; that makes it a zero-backlash interface that’s quiet … … and speaking of backlash, the gearheads themselves have low backlash ranging from 0.25 to 0.35 under no load.
