An ingredient found in red wine can combat the harmful effects of obesity and reduce the risk of disease in the elderly, a clinical trial has shown for the first time.
Today’s wireless-sensor networks can do everything from supervising factory machinery to tracking environmental pollution to measuring the movement of buildings and bridges. Working together, distributed sensors can monitor activity along an oil pipeline or throughout a forest, keeping track of multiple variables at a time.
Some regions of the U.S. anticipate future prosperity even as the national economy struggles. Though unlikely to surpass powerhouses of the U.S. economy such as California’s Silicon Valley, Boston’s Route 128 corridor and North Carolina’s Research Triangle, these five cities may well give better-known up-and-comers such as Austin, Texas, Charlotte, N.C., Denver and the Sun Belt’s auto centers a run for the money.
According to a new report from the U.S. Energy Information Administration (EIA), the consumption of engery from renewable sources recently topped both the current and the historical consumption levels for nuclear energy. The shift was immediately caused by nuclear outages that coincided with the high-water season for hydropower generation.
But there’s a long-term upward trend in renewables which can be seen here, too, thanks to the increased consumption of biofuels and wind capacity additions…
Professor Manos Tentzeris displays an inkjet-printed rectifying antenna used to convert microwave energy to DC power.
Researchers have found a way to capture and harness energy transmitted by such sources as radio and television transmitters, cell phone networks and satellite communications systems. By getting this ambient energy from the air around us, the technique could provide a new way to power networks of wireless sensors, microprocessors and communications chips.
The French government of Nicolas Sarkozy has launched a €10 billion ($14.26 billion) tender to build about 1,200 wind turbines in 5 different offshore wind farms. The goal is to diversify France’s energy generation (they are very reliant on nuclear, which accounts for about 80% of their electricity generation) with renewable sources and to have 23% of France’s energy come from renewable sources by 2020. The wind farms will be located off France’s coast on the North and West and should produce about 3.5% of the country’s electricity according to government authorities. The farms should come online between 2015-2020…
The average household’s energy costs would be cut by 7% or $85 every year.
Making it’s way through the U.S. Congress is a bill that would block certain provisions from a 2007 energy law signed by George W. Bush that “effectively bans the 100-watt incandescent bulb next year and other versions subsequently”. The law simply mandates that bulbs need to be 30% more energy efficient, an improvement that could have great economic and environmental benefits.
There are 160 million set-top boxes in the United States.
That cable box that sits on top of your television and ushers in cable signals and digital recording capacity into tv has become the single largest electricity drain in many American homes. Some typical home entertainment configurations eat more power than a new refrigerator and even some central air-conditioning systems.
There are 440 commercial nuclear reactors in use worldwide. They are all currently helping to minimize our consumption of fossil fuels. But how much bigger can nuclear power get?
