Batteries are History With New Flashlight Technologies

Minneapolis, MN (ContentDesk) November 4, 2005  The flashlight industry has come along way since 1898 when Conrad Huberts first patent for the Eveready flashlight consisted of a hand-made paper, fiber tube, bulb and a rough brass reflectors that generated a mere flash of light.
Since then, breakthroughs each decade have shed light into every corner of our lives.The latest innovation in the light business is the state-of-the-art LED flashlight.
LED or Light Emitting Diode is powered by converting the energy of motion into electrically energy by repeatedly passing a high-power magnet through a coil of wire.
A capacitor then stores the electrical energy to power the white light LED.
LED flashlights will never need batteries or charging since its energy source is motion.

LED flashlights also do not use bulbs.
Bulbs burn with heat, break under pressure, and die relatively quickly.
LEDs are tiny light bulbs that fit into an electrical circuit and are illuminated solely by the movement of electrons in a semiconductor material. But, unlike ordinary flashlight bulbs, they are quite durable, they don't generate a significant amount of heat, and because there is no filament to burn out, they typically last for thousand of hours according to the experts at flashlightguide.com.It was a long time coming, this renewable energy storage system.
After Huberts initial invention, it was 12 years before the next big step:
nickel-plated tubes that complemented vulcanized fiber.

With the new tungsten filaments, the modern version was well on its way.Flashlights by the 1920s had become a household essential.
By 1966 thermoplastic molding encased the ever-evolving bulb systems, and in the following year the batteries were now rechargeable.
In 1968 the world was introduced to the first fluorescent lanterns and in 1984 the first halogen flashlight.Some attempts have been made to utilize solar energy as the power source for flashlights, but these models, though environmentally-friendly, are bulky (with solar panels), expensive, and not especially efficient.Flashlight futures seem to be gravitating towards the LED, since it is the most durable, efficient, and powerful model to date.

Kids To Improve Their Summer Fire Safety Know-How

(NC)-When Canadians think of summer, they conjure up images of vacations and long-weekend getaways, camping, picnics, spending time with the kids and, of course, going to the cottage. It is a time when relaxing in the sun and having a good time are at the forefront of everyone's mind. However, according to the Canadian Association of Fire Chiefs (CAFC), studies have shown that summer, in particular, tends to be the most dangerous time of year for children, especially with respect to fire-related incidents. In fact, the number of children playing with fire increases dramatically during the summer. Even more frightening, children in North America are more likely than adults to die or be seriously injured in fires.

"Children are naturally curious about fire, and have more free time on their hands during the summer to find things around that house that can be potentially hazardous - like matches, lighters and cooking appliances," says Ken Kelly, president, CAFC. "Sadly, most don't...

A Guide To Cell Phone Batteries

Cell phones are one of the best innovations of the past decade. They have ushered in an era where anyone can be connected to others, anywhere, anytime. Text messaging has become a fad, not only among the youth but also on the corporate level. There is hardly anyone without a cell phone these days.

And as it is with technology, the cell phone has evolved in many ways. In fact, it may be the fastest evolving gadget there is, with new models being introduced to the market within just a month of one another.

Aside from sophisticated gaming capabilities, most phones now feature Internet browsing via WAP, video and photo cameras, radio and MP3 players. Some even have the functions of handheld PCs, allowing word processing and presentations. All these extra applications use a lot of power.

Most cell phone batteries are Lithium Ion (LiOn)?the most lightweight rechargeable battery kind that does not have an effect on memory.

Electric flight - the best and worst of Li-Po

Copyright 2006 Bravos Direct

What happened to that mosquito snarl that always seemed to accompany the sight of model airplanes?
The answer is they're going electric and silent.
Li-Po (Lithium Polymer or Li-Poly) batteries are rapidly becoming the standard power source for electric model airplanes. Li-Po batteries are smaller, lighter and hold more power than their predecessors (Nickel Cadmium and Nickel Metal Hydride). There are three specifications that need to be taken into consideration when making a Li-Po battery purchase for your electric model airplane.

The voltage of the battery will tell you how powerful it is, the amperage rating will give you an idea how long it will last, and the burst/constant power rating will tell you how quickly the power will discharge. A major difference between Li-Po batteries and others available for RC model airplane use is that it is much easier to mistreat the battery thereby creating unsafe situations...
