BOSTON, Feb. 4 /PRNewswire/ -- With solar electricity generating more than one terawatt-hour (one billion kilowatt hours) of electricity in the United States in 2010 and continuing to expand rapidly, the key question is, "How can companies best capture value as the industry grows?", according to Michael Rogol, global PV analyst and CEO of Boston-based PHOTON Consulting. "The U.S. solar power sector is very profitable, but value is migrating from companies that manufacture toward companies...

BOSTON, Jan. 29 /PRNewswire/ -- In his State of the Union address to Congress, US President Obama highlighted the importance of solar power to America's future and stressed that, "It is time for America to lead again." With the strong support of government incentives and declining system prices, demand for solar photovoltaic (PV) systems in the United States is showing steady growth, yielding an increasing number of watt-hours of solar electricity generation and solar jobs. For the first...

BOSTON, Jan. 13 /PRNewswire/ -- Solar companies at every step of the global PV supply chain must begin to focus resources on developing the end-markets that will support the industry in the event of another major market saturation, according to the recently released market report by PHOTON Consulting, Solar Power Markets: Prepare for Impact. "During 2009, the global PV sector became overly dependent on a few dominant end markets. As rapid supply growth returns to the sector, we fear that...

Quantum entanglement achieved in solid-state circuitry For the first time, physicists have convincingly demonstrated that physically separated particles in solid-state devices can be quantum-mechanically entangled. The achievement is analogous to the quantum entanglement of light, except that it involves particles in circuitry instead of photons in optical systems. Both optical and solid-state entanglement offer potential routes to quantum computing and secure communications, but solid-state...

Researchers at the California Institute of Technology (Caltech) have proposed a new paradigm that should allow scientists to observe quantum behavior in small mechanical systems. Their ideas, described in the latest online issue of the Proceedings of the National Academy of Sciences, offer a new means of addressing one of the most fascinating issues in quantum mechanics: the nature of quantum superposition and entanglement in progressively larger and more complex systems. A quantum...

Nanotechnology has already made it to the shelves of your local pharmacy and grocery: nanoparticles are found in anti-odor socks, makeup, makeup remover, sunscreen, anti-graffiti paint, home pregnancy tests, plastic beer bottles, anti-bacterial doorknobs, plastic bags for storing vegetables, and more than 800 other products. How safe are these products and the flood of new ones about to spill out of labs across the world? A group of researchers at Washington University is devising instruments...

MIT researchers have developed a new way to tune the frequency of lasers that operate in the terahertz spectrum. The result is an important step toward airport scanners that could tell whether a vial in a closed suitcase contains aspirin, methamphetamines or an explosive. Tucked between microwaves and infrared rays on the electromagnetic spectrum, terahertz rays can penetrate clothing, plastic, and human tissue, but they're thought to be safer than x-rays. Since they're absorbed to different...

To exploit the quantum world to the fullest, a key commodity is entanglement"”the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded from one another. Now, physicists at the Joint Quantum Institute (JQI), a collaborative organization of the National Institute of Standards and Technology (NIST) and the University of Maryland, have developed a promising new source of entangled photons using quantum dots tweaked with a laser....

The first experiments are now underway using the world's most powerful X-ray laser, the Linac Coherent Light Source, located at the Department of Energy's SLAC National Accelerator Laboratory. Illuminating objects and processes at unprecedented speed and scale, the LCLS has embarked on groundbreaking research in physics, structural biology, energy science, chemistry and a host of other fields. In early October, researchers from around the globe began traveling to SLAC to get an initial...

Electromagnetic Spectrum -- The electromagnetic spectrum describes the various types of electromagnetic radiation based on their wavelengths. Radio, representing wavelengths from a few feet to well over a mile, is at one end of the spectrum. Gamma ray radiation is at the other end: the wavelength of the harder types is so short, in the subatomic range, that we do not have instruments capable of directly measuring it. While the above classification scheme is generally accurate, in...

Electromagnetic Radiation -- Electromagnetic radiation is a combination of oscillating electric and magnetic fields propagating through space and carrying energy from one place to another. Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism. When any wire (or other conducting object such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
