Offshore Wind Farms Vulnerable To Hurricanes
2012-02-15 14:34:29

In a world of green energy aficionados, offshore wind farms have become all the rage. Yet with the U.S. poised to invest untold billions in the environmentally friendly power source, a recent study has caused many to question the financial liabilities associated with what now seems a very risky investment. According to a study published Monday in the Proceedings of the National Academy of Sciences, yearly offshore hurricanes would likely destroy roughly half of the proposed wind turbines...

In the effort to convert sunlight into electricity, photovoltaic solar cells that use conductive organic polymers for light absorption and conversion have shown great potential. Organic polymers can be produced in high volumes at low cost, resulting in photovoltaic devices that are cheap, lightweight and flexible. In the last few years, much work has been done to improve the efficiency with which these devices convert sunlight into power, including the development of new materials, device...

A relatively fast, easy and inexpensive technique for inducing nanorods - rod-shaped semiconductor nanocrystals - to self-assemble into one-, two- and even three-dimensional macroscopic structures has been developed by a team of researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab). This technique should enable more effective use of nanorods in solar cells, magnetic storage devices and sensors. It should also help boost the electrical and...

The high resolution of Lawrence Berkeley National Laboratory´s Gang Ren When Gang Ren whirls the controls of his cryo-electron microscope, he compares it to fine-tuning the gearshift and brakes of a racing bicycle. But this machine at the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) is a bit more complex. It costs nearly $1.5 million, operates at the frigid temperature of liquid nitrogen, and it is allowing scientists to see what no one...

Developments by hydrogen researchers at the U.S. Department of Energy's (DOE) Savannah River National Laboratory (SRNL) are paving the way for the successful development of portable power systems with capacities that far exceed the best batteries available today. SRNL's advances in the use of alane, a lightweight material for storing hydrogen, may be the key that unlocks the development of portable fuel cell systems that meet the needs for both military and commercial portable power...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
