A wind farm is a group of wind turbines in the same location used for production of electric power. Individual turbines are interconnected with a medium voltage power collection system and communications network. At a substation, this medium-voltage electrical current is increased in voltage with a transformer for connection to the high voltage transmission system.…

Bedbugs or bed bugs are small parasitic insects of the family Cimicidae. The term usually refers to species that prefer to feed on human blood. All insects in this family live by feeding exclusively on the blood of warm-blooded animals. The name bedbug is derived from the insect’s preferred habitat of houses and especially beds…

Dark matter in cosmological terms is matter that is inferred to exist from gravitational effects on visible matter and background radiation, but is undetectable by emitted or scattered electromagnetic radiation. Its existence was hypothesized to account for discrepancies between measurements of the mass of galaxies, clusters of galaxies and the entire universe made through dynamical…

It is a buzz word nowadays. Green is good. there is green chemistry, green products, and green foods. How much green is good and how much is just lip service is another matter. Green is more that that the product is sustainable or based on recycled materials in this case. Researchers found that more than…

Which is better to be? Wild and free or tame and domesticated? That has always been an interesting philosophical question. Professor Mark Viney and colleagues at the University of Bristol compared the immune function of wild mice who have to find their own food with that of mice bred in captivity who have all food…

Ten European countries, including Norway, have agreed to develop an offshore electricity grid at the North Sea, in a bold move that promoters say will give Europe the possibility of tapping into an even bigger source of energy than the Middle East’s oil capacity. Ministers from all the ten ‘North Seas Countries’ signed of a…

Ideally a location for the generation of solar power should have a relatively high level of solar insolation (ability to generate a significant amount of solar energy), a fairly large amount of economic activity to result from solar energy being deployed, a reasonably low cost of energy installation, higher than average current prices for electricity,…

When will production of oil and coal peak? After the peak, production will decline because supplies are being depleted and no new sources are to be found. Peak oil is the point in time when the maximum rate of global petroleum extraction is reached, after which the rate of production enters terminal decline. Optimistic estimations…

A holiday is supposed to be a fun off day to enjoy life in some fashion. For the second time in a month, heavy air pollution in Iran’s smog-filled capital has forced authorities to close government offices and schools and declare a two-day public holiday because of the health dangers of being outdoors. Yet this…

There were no reported hurricane disasters like Katrina that hit New Orleans in 2005. So it is somewhat surprising to hear that according to NOAA (National Oceanic and Atmospheric Administration,) the 2010 Atlantic hurricane season, was one of the busiest on record. In contrast, the eastern North Pacific season had the fewest storms on record…
