Top 10 Computing Energy Savers

Reducing the amount of energy your hungry computers eat up every day won't only save you money on electricity bills, it will reduce your carbon footprint. If you haven't thought about how much electricity your gadgets use up every day, now's the time. Turns out just a few changes in habits and system settings can save you money AND the environment. After the jump, have 10 ways to reduce your energy consumption and compute greener.

The site lists 10 tips for reducing the amount of energy your computer (and other devices) waste. Each tip has a link giving more information (e.g., what a "smart power switch" is).

Women more dominant than men

WebMD : Wives Wield Decision Power in Marriage

Balance of Problem-Solving Power Weighs in Favor of Women

Men may rule the world but women rule the roost, according a new study that shows women wield considerably more decision-making power than men within marriages.

Researchers found that wives, on average, displayed more power than their husbands during problem-solving discussions, regardless of who brought up the topic of discussion.

And it’s not simply a case of women talking more than men.

“It wasn’t just that the women were bringing up issues that weren’t being responded to, but that the men were actually going along with what they said,” researcher Megan Murphy, assistant professor of human development and family studies at Iowa State University, says in a news release. “They were communicating more powerful messages, and men were responding to those messages by agreeing or giving in.”

“There’s been research that suggests that’s a marker of a healthy marriage – that men accept influence from their wives,” Murphy says.

Wireless Power Transmission

Farewell, wires? Power beamed through air

‘WiTricity’ can light up lamps and laptops; system touted as safe, efficient

Power cables and even batteries might become a thing of the past using a new technique that can transmit power wirelessly to cell phones, laptops, MP3 players, household robots and other electronics.

Scientists lit a 60-watt light bulb from a power source 7 feet (2 meters) away with their new technique, with no physical connection between the source and the appliance. The researchers have dubbed their concept "WiTricity," as in "wireless electricity."

Soljacic and his colleagues devised WiTricity based off the notion of resonance. One well-known example of resonance can be seen when an opera singer hits the right note to cause a champagne glass to resonate and shatter. Two objects resonating at the same frequency tend to exchange energy efficiently, while interacting weakly with objects not resonating at the same frequency.

Instead of sound, the MIT physicists focused on magnetic fields. Most common materials interact only very weakly with magnetic fields, so little power would get wasted on unintended targets. "The fact that magnetic fields interact so weakly with biological organisms is also important for safety considerations," said Soljacic's colleague, MIT physicist Andre Kurs.
