Lightning Safety Awareness Week
2012-06-26 06:33:07

redOrbit Meteorologist Joshua Kelly The week of June 24-June 30 is noted as “Lightning Safety Week”. So what are some things that you can do when you hear the first crackle of thunder? One of the first things to do is take cover inside a shelter such as a house, garage or even patio. The next thing you can do to help prevent injury is not run for cover under a tree or object outside that can easily be attracted to lightning. A third thing is try to avoid using appliances and...

The Death Of The Battery?
2012-06-17 03:00:00

Battery-powered devices could soon be a thing of the past thanks to a group of UK researchers who have created a novel energy harvester to power some of the latest wearable gadgets. By strapping the energy harvester to the knee joint, a user could power body-monitoring devices such as heart rate monitors, pedometers and accelerometers by simply walking and not have the worry of running out of power and replacing batteries. Soldiers may find this device particularly useful as they often...

A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. The first-of-its-kind "pyroelectric nanogenerator" is the topic of a report in ACS' journal Nano Letters. Zhong Lin Wang and colleagues at Georgia Tech explain that more than 50 percent of the energy generated in the U.S. each year goes to waste, much of it as heat released to...

"When Lightning Strikes" by Kay and Bobby Brunson is the story of a man struck by lightning and visiting heaven for 28 minutes. The Christian Coalition has highlighted the book as providing comfort to those experiencing the loss of a loved one. Charleston, South Carolina (PRWEB) May 25, 2012 Imagine being struck by lightning and being considered dead for 28 minutes, only to return to your life with a stunning glimpse of the hereafter. Bobby Brunson says he did and lived to tell his story...

Portable, Virus-Powered Recharging Source On The Horizon?
2012-05-14 03:26:01

[ Watch the Video ] Researchers from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) report that they have found a way to convert mechanical energy into electricity using viruses. The discovery, announced via a Sunday press release, involved miniature devices that can harvest the effort of day-to-day tasks and convert it into power to charge smartphones and other devices while a person is out walking. "The scientists tested their approach by creating a...

Power Generation Technology Based On Piezoelectric Nanocomposite Materials Developed By KAIST
2012-05-07 08:50:50

The team of Professor Keon Jae Lee (http://fand.kaist.ac.kr/) from the Department of Materials Science and Engineering, KAIST, has developed new forms of low cost, large-area nanogenerator technology using the piezoelectric ceramic nanoparticles. Piezoelectric effects-based nanogenerator technology that converts existing sources of nonpolluting energies, such as vibrational and mechanical energy from the nature of wind and waves, into infinite electrical energy is drawing immense interest...

The boundary between electronics and biology is blurring with the first detection by researchers at Department of Energy's Oak Ridge National Laboratory of ferroelectric properties in an amino acid called glycine. A multi-institutional research team led by Andrei Kholkin of the University of Aveiro, Portugal, used a combination of experiments and modeling to identify and explain the presence of ferroelectricity, a property where materials switch their polarization when an electric field is...

When we think of thunderstorms we have to remember the deadliest part of those storms and that is the lightning that occurs with them. Lightning is found in many forms. The first type of lightning is known as cloud to cloud meaning that the electric charge travels from one cloud to the other. The second type of lightning is the Cloud to Air meaning the lighting moves from the cloud and enters the clear air of the sky. A third type of lightning is the cloud to ground. This is the most...

A Radio Atmospheric signal (sometimes referred to as Sferic or Spheric), is a broadband electromagnetic impulse that occurs during atmospheric lightning discharges. Sferics spread out from the lightning source and can be received thousands of miles away. A sferic, depending on atmospheric conditions, may extend anywhere from a few kHz to several tens of kHz. Sferics from far reaching storms, over 1500 miles away, are generally offset in frequency range and may be picked up as tweeks. A...

Heat Lightning is actually faint flashes of lightning reflecting outward from distant thunderstorms. These flashes usually do not produce thunder as the storm is sometimes too far away to be heard. The term heat lightning got its name because it often occurs on hot summer nights and does not produce audible thunder. One reason heat lightning can be seen so far away is due to the reflection of the light bouncing off water particles in moist, humid air and as light is scattered throughout the...

Aurora -- The Polar Aurora are natural displays of light in the sky that can be seen with the unaided eye only at night. An auroral display in the Northern Hemisphere is called the aurora borealis, or the northern lights; in the Southern Hemisphere it is called the aurora australis. Auroras are the most visible effect of the sun's activity on the earth's atmosphere. The beautiful and often eerie curtains of light in the night time sky have been observed by people for millennia. An aurora...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
