With all of the excitement surrounding LEDs these days, high-intensity discharge (HID) lamps are still popular due to their high brightness, excellent color temperature and long lifetime.
(No, this post has nothing to do with a certain twenty-four-year-old, side-scrolling action game series.)
In a previous episode, the subject of wind turbines was briefly discussed. They could be considered in an ‘esoteric’ class because of their various disadvantages, primary among them is the lack of reliability, i. e., if the winds don’t blow or they blow too fast, there is no electricity.
This week, you read about some ways you can use shade to keep your home cool in the spring and summer. Some people are lucky enough to have a lot of trees for natural shade, while others of us have to create our own.
Last month, Sony essentially neutered the PlayStation 3 by removing its “Install Other OS” functionality. This precipitated a huge customer backlash (and, as of this writing, at least two class-action lawsuits), but there’s one foe Sony hadn’t anticipated—the United States Air Force.
Quite often, technology starts at the high-end (military, expensive lab gear or enterprise) and then with time as volumes rise it becomes affordable and moves into the mass-market.

My dad is obsessed with fuel efficiency. I joked with him on a recent road trip that when he retires, he'll have more time to pursue his dream career as a fuel-economy promoter. Well guess what, I just found the treasure trove of information on smart driving that's going to make his whole...
Spring is my favorite time of year. The snow (finally!) stops, the temperature is perfect, and everything is colorful again. We rarely need to turn on the heat or air conditioner to stay comfortable at home, and there's nothing better than a relaxing evening on the deck.
This week, Amy discussed ENERGY STAR lighting fixtures and how they can you save on lighting costs. Lighting accounts for roughly 11% of a typical residential utility bill, so it's worth seeking ways to reduce your energy use and costs. ENERGY STAR fixtures, efficient lighting choices,...
Lasers have been described as the “holy grail” of weapons—who wouldn't want to be like Luke Skywalker? But while researchers have pondered everything from “pain rays” to the “Zeus” anti-IED system, the folks over at LaserMotive are pushing something else entirely—power beaming for UAVs.
This past October, we wrote a lot about the U.S. Department of Energy Solar Decathlon. If you haven't heard of the Solar Decathlon, it's a competition held every two years that challenges 20 collegiate teams to design, build, and operate solar-powered houses that are cost-effective,...
In 2007, SSG David Bellavia released the most poignant memoir of the Iraq War, “House to House.” The title is significant, because house-to-house fighting is among the most dangerous forms of urban warfare. Camero may have a solution with the Xaver 400, a compact through-wall radar.
My husband and I spent a lazy Saturday in a lighting showroom a few weekends ago. We've been working on a project to replace all the lighting fixtures in our home for a couple of years now, so we seem to spend a lot of time in lighting showrooms. But that particular Saturday was a bit...
