Productive Product: Not everyone can live in a solar-powered European city or build a solar-powered cubist house, but Iqua Ltd.'s solar Bluetooth headset will soon be available to all, the Register reports. Will it work when the skies are cloudy or dark? Will it have comparable sound quality and between-charges life to standard headsets? Will it cause any sunburn on your ear?
Energy News: More from the NREL: they announced that a photovoltaics start-up, Wakonda Technologies, is the winner of the Clean Energy Entrepreneur of the Year award. Wakona's name derives from a native American word regarding spirit and nature; they're working on thin films of gallium arsenide for solar cell substrates. Typically thin-film
Op-Ed: Plenty of energy-efficiency news piled up while I was on vacation last week. Much of the time I was at the Mountain View, Calif. Computer History Museum, where they happen to be hosting a few Smart cars. That made me wonder what I was missing back home, so here are

Energy News: City officials in Ann Arbor, Michigan announced a two year plan to convert all 1,046 of its 120W incandescent downtown streetlights to efficient 56W LEDs. They say the $630,000 installation project will save the city $100,000 per year and will reduce
Productive Product: No, that's not a misspelling: Energizer markets its lithium (not li-ion) backup system for portable gadgets with the "Energi To Go" moniker. Basically this is a battery holder fitting one or two AA cells, a power charging and management chip from Techtium, and your connector
VIDEO | Op-Ed: Here's an example of energy savings at a technology conference. MOS 6502 and Commodore legend Chuck Peddle planned to fly to New Jersey to give a 90-minute computer history lecture. But he was stuck in Sri Lanka for his job, so he videoconferenced instead. The twist: instead of using an expensive, professional videoconferencing "solution", Chuck used ordinary Skype
Op-Ed: Recently we added some new sites to our link library. The total is up to 49 but the three newest are off the beaten path: the Athena Institute, GreenDrinks, and WattWatt. (We truly hope to refer you to sites that are useful, not just a million and one blogs and such.
Energy News: America's demand for clean energy will beat supply by 37 percent in 2010, the National Renewable Energy Lab will report next week -- that's according to USA Today. They also explain how half of the states require certain percentages of their providers' power to come from clean energy
Energy News: CNN posted a very solid overview story about the state of solar power. The technology, if we lived in a proverbial vacuum, can already provide all the world's energy needs by installing panels in a small corner of the Sahara. But in the real world, cost and security are
Energy News: More than a third of enterprise CIOs don't monitor their corporate energy use, according to an Economist Intelligence Unit report, commissioned by IBM. "Although concerns about energy efficiency and global warming are now high on the political agenda, the spotlight
Productive Product: Fairchild Semiconductor’s 600V/30A IGBT, the FGH30N60LSD, addresses the need for low conduction losses in low-frequency (50 Hz to 400 Hz) industrial applications such as solar inverters, welding machines and uninterruptible power supplies (UPS). Featuring extremely low saturation voltage
Productive Product: Micrel launched the MIC2238, a 2.5 MHz dual 800 mA synchronous buck (step-down) regulator housed in a 3 mm × 3 mm MLF package. Its unique switching architecture scheme, Trickle Mode, enables desirable light load efficiency for Li-Ion battery powered systems that require maximum efficiency in order to prolong use. The MIC2238 is appropriate for portable applications including cellular phones, portable media players, WiMax modules, GPS systems, digital still and video cameras.

Energy News: DNA from salmon -- specifically, from the fish's sperm -- makes an excellent choice for building extra-bright, biodegradeable light-emitting diodes, researchers at the University of California / Riverside found. It sounds fishy but it's true. “DNA has certain optical
Op-Ed: There's a blog post over at CNET about an E85 Dodge Viper which is breaking speed records. They wrote, "More than doubling the horsepower probably had a big effect on the performance of the car, but the extra octane can't hurt. Ethanol also cuts down on the greenhouse gases from the tailpipe."
Energy News: Two interesting stories today from eWeek: first, the Green Grid member companies signed a Department of Energy agreement for data center metrics; second, coverage of Energy Star director Andrew Fanara's declaration that volume servers are so obviously bad for the green agenda.
Op-Ed: The full story isn't clear here, but it looks like a government crackdown on the very popular Alameda County Computer Recycling Center. For readers not in the Silicon Valley area, I can personally attest that ACCRC is a well-run, well-supported organization which does a valuable community service. So why would an EPA inspector
Productive Product: Let's start by clarifying a vital point: this story is about solar power adapters for conventional PCs, not about "solar-powered PCs" per se. You don't actually get a solar panel slapped to the side of your tower case; you get 86 pounds of schleppability. But you also get to help save the planet and circumvent your local

He says there is plenty of room for smart investments into alternative energies, because there wasn't much of a bubble in the first place, nor was there a bubble 30 years ago when many of the same technologies were going to save us from
Productive Products: Human harvesting. Algae pools. Wave power. Artificial tornados. Super kites. Tesla coils. The list reads like a high-tech version of the plagues that freed Moses' people in Egypt, but will these alternative energy concepts succeed or have the proverbial sea crash down on them? "True, many of the kookier-sounding concepts are still in deep development within large corporations, universities, and
