The four soldiers move from their concealed position and “stack” themselves, one behind the other, parallel to the door. The #2 man throws an M84 grenade (flashbang) into the room, then yells “frag out!” The flashbang detonates, and the fire team storms through the “fatal funnel” (door).
Last week, the Environmental Protection Agency announced its new green homes Web site. The site provides an interactive experience that helps people
Here's a good article by Phil on SolidWorks 2010. I like the bio at the end: Phil Sluder is a mechanical engineer, owner of TriAxial Design and Analysis, certified SolidWorks instructor, certified SolidWorks professional, a longtime member of the SWUGN committee, and leader of the San...
This week, John discussed buying clean electricity from your utility. If you can't set up a small renewable energy system of your own, buying clean electricity is a great way to support the use of renewable energy.
In my last post I discussed Forth as a language. A language that is based on a virtual machine. What if that virtual machine was turned into a real machine? Good things. For one operations can be done in parallel. Returns can be automatically initiated at the end of an instruction cycle.
Russia has jumped on the CFL bandwagon, and decided to ban the incandescent bulb. As of January 1, 2014, the manufacture and sale of all incandescent bulbs will be prohibited in Russia.
Back in March, we reported on the California Energy Commission’s proposal to set a cap on the maximum active mode power usage (watts) for TV’s. All units above the maximum would be banned for sale in California—this would preclude the vast majority of Plasma, DLP, and Rear-projection TV’s.
Earlier, we reported that global investments in renewable energy had dipped 40% from 2008-09—thus, the following comes as welcome news. George Soros has decided to invest $1 billion of his own money into “green technologies.” Soros issued a clear directive on how his money ought to be spent
Helix Wind Corporation gave an update today on its efforts to provide cost-effective renewable energy solutions to telecommunications companies. Helix’s wind turbines can lower the costs of operating expenses associated with cell phone towers in remote locations.
The Fraunhofer Institute for Chemical Technology (ICT) has developed a redox flow battery that could become the gold standard in Advanced Technology Vehicles. If the claims hold up, this battery would be a true breakthrough. There’s nothing revolutionary about the concept of redox flow batteries.
Residents of a West Bank village with no electricity have been helped out of the darkness by unlikely benefactors - a group of Israelis who installed solar panels and wind turbines to illuminate the Palestinians' makeshift homes. The villagers of Susya live in tents and caves with power lines darting right above their dwellings
Global investments in renewable energy technology dipped 40% from 2008-09—this according to United Nations Industrial Development Organization Director, General Kandeh Yumkella. “Due to the current economic crisis we have seen almost a 40 percent decline in 2009 alone in these investments,” said Yumkella at a global conference on green energy in central Mexico.
From strawberry jam jars to frozen french fries, the manufacturing plants that make several well-known container and food items in the United States can now earn the U.S. Environmental Protection Agency’s Energy Star for superior energy efficiency. The new Energy Performance Indicators (EPIs) for flat and container glass manufacturing plants
The organic light emitting diode (OLED) display is becoming more and more popular, especially for mobile phones, media player and small entry level TVs. Contrary to a standard liquid crystal display, the OLED pixel is driven by a current source. To understand how and why the OLED power supply impacts the display picture quality, it is key to understand the OLED display technology and power supply requirements.
Toshiba will become a big player in optoelectronics—if their lighting division has its druthers. The company will release high-output LED light bulbs with a total flux equivalent to that of a 60 W incandescent lamp. The “natural white” type and the warm white type feature total fluxes of 810 lm and 600 lm, respectively.
