Latest Electrical phenomena Stories
A lightning researcher at the University of Bath has discovered that during thunderstorms, giant natural particle accelerators can form 40 km above the surface of the Earth.
Scientists are reporting an advance toward scavenging energy from walking, breathing, and other natural body movements to power electronic devices like cell phones and heart pacemakers.
PALM BEACH, Fla., Feb. 11 /PRNewswire/ -- U.S.
High-energy bursts of gamma rays typically occur far out in space, perhaps near black holes or other high-energy cosmic phenomena - so imagine scientists' surprise in the mid-1990s when they found these powerful gamma ray flashes happening right here on Earth, in the skies overhead.
Power-generating rubber films developed by Princeton University engineers could harness natural body movements such as breathing and walking to power pacemakers, mobile phones and other electronic devices.
Scientists and engineers have developed a â€˜smart armorâ€™ that has the ability to recognize the size of bullets it is shot with and generate electrical power upon impact.
A group of researchers at the City College of New York is developing a new way to generate power for planes and automobiles based on materials known as piezoelectrics, which convert the kinetic energy of motion into electricity.
There is good news for the global effort to reduce the amount of lead in the environment and for the growing array of technologies that rely upon the piezoelectric effect.
Every year, scientists learn something new about the inner workings of lightning.
A freak bolt of lightning struck a 56-year-old cyclist in Englewood, Colo, even though no electrical storms were reported in the area, authorities say.
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...
