What Makes A Solar Powered Flashlight Work?
July 19th, 2010
Generally speaking, a solar powered flashlights looks quite like any ordinary flashlight. There’s a simple on and off switch. One end of the flashlight has an area that emits light…enough light to allow you to be able to see a small area at night, or into a darkened recess.
Using sunlight energy, a solar powered flashlight converts that energy into electrical power in a solar photovoltaic (PV) cell or panel that sits on the outside cover of the flashlight. The solar generated power is stored in a battery. A Light Emitting Diode (LED) lamp is generally used in a solar powered flashlight instead of an incandescent light bulb, because LED’s last longer, and take less electrical current to operate. LED’s, on average last for about 10,000 hours, compared to an incandescent light that has lasts about 1,000 hours.
Solar charged batteries, like the LED’s are much more effective than their conventional counterparts, the nickel lithium or cadmium batteries one usually finds in flashlights. A solar charged battery will last about two years, or 2500 hours, while the single use nickel, lithium, or cadmium batteries are really good for about 15 hours of regular use.
To maximize the usage of your solar charged batteries, you should leave the flashlight on for 15+ hours at least once a month to fully expend the charge. Rechargeable batteries have a memory effect. Therefore if you continually use the flashlight without ever fully discharging it, it will eventually only recharge to a lower (memory) level, and never return to 100 percent of its available power.
For best results, keep your solar powered flashlight on a window sill when it is not in use, where the solar panel is exposed to the maximum amount of sunlight. If you’re not using it regularly, be particularly mindful to turn it on…and leave it on…as described above, at least once a month.
You don’t have to look very hard any more to find a solar powered flashlight in a hardware store. They’re great lights for emergency use, and for camping. It’s good to have at least one in your home, and in each of your vehicles. It’s a good idea if for no other reason than to lower your worry level. Remember all those times you needed a flashlight in a hurry, found it, discovered the batteries were dead and you didn’t have any spares…or at least didn’t know where they were?
Some amazingly innovative designs are being created for solar flashlights…with add-ons like siren, flasher, cell phone charger, etc… in addition to the basic flashlight design. There are also any number of solar flashlight key chains are on the market today. The price range varies, depending on the uniqueness of the style, the outside casing, and additional functions.
Would you like to “spread the light” in a very solar way? If so, please visit bogolight.com. BOGO stands for buy one, give one. A limited liability company founded by Mark Bent in 2006 named SunNight Solar operates the BoGoLight Program. Mark served in the Diplomatic Corps prior to that, and was in a number of developing countries. What he saw there convinced him there was a need for light in many places, so he set about finding a way to meet that need. In the BoGoLight Program, you purchase one solar flashlight at BoGoLight or one of its affiliates (there’s one called InHabitat), and that generates the purchase of another identical solar flashlight. The donations are sent to a non-profit organization that’s been set up to collect and ship these flashlights all over the world to the many places they’re needed.
Isn’t it awesome to shine a little light…in a very solar way…for those who sit in the dark at night and cannot see?

Electric Cars: Wonders Of Utility Automobiles
June 10th, 2010
For sure, at some point, you’ve heard inside news or read inside newspaper the wonders of electrical automobiles. You will discover quite a few factors why electronic automobiles are all over the bulletins appropriate now. A single point behind this phenomenon is that utility automobiles are sorts of vehicles that’s powered by fuel cells. And due to the fact the rise of fuel prices are acquiring noticed by the public, the benefit of an electrical vehicle is clearly seen.
Yet another motive electric autos are famous is simply because electronic cars and trucks are environmentally friendly due to the fact they generate less pollution than the standard gasoline-powered vehicles. And just one additional explanation about the hype is since in the stories in regards to the hybrid electronic cars and trucks that are largely owned by celebrities that promotes the ‘Green Movement’.
Most of the time, utility vehicles are not bought brand new by automobile owners rather a conversion of their previous regular automobile. In plain site you are going to somewhat have a difficult time to spot if the car or truck is a power a single or not. Just one method to point out if the motor vehicle can be a converted utility car or truck is the sound of it. Typical gasoline-powered autos are a little loud and power autos are practically silent. Nevertheless, you can easily distinguish the make with the auto once the hood is popped-up. If a typical gasoline-powered auto is converted to an electric powered car or truck then you definitely will notice that the following:
1. The fuel engine is traded for an electronic motor,
2. The controller obtains it power from the selection of rechargeable batteries and
3. The electrical motor gains its energy by way of the controller.
Power vehicles are usually defined like a refined wiring project. Contrariwise, mainly because of its fuel lines, colorant hoses, exhaust pipes and entry manifolds, a frequent gasoline-powered car or truck is defined being a rough plumbing project.
So why decide on an electrical automobile against frequent car? One more reason is mainly because utility automobiles offer a distinct experience in driving. Most of electric powered autos, since of their low center of gravity, provide outstanding handling along with swift initial increase of velocity. Even at lower pace or speed, electrical motor presents almost incessant rotating force that allows the car or truck to do things that normal or traditional petroleum based vehicles can not do. One excellent case of point of this is when you are driving a regular gasoline-powered auto and you’re steering up to a curb in a street. Using the standard motor vehicle there’s still a have to have for you personally to stop, aim to climb the curb and kick-start the motor to reach your goal. But with an electronic auto, it will probably be a breeze in your case to climb the curb.
Converting normal gasoline-powered cars to electrical automobiles have so numerous other advantages as well. And naturally, it also has its share of drawbacks. To fully comprehend how you can convert one particular yourself or comprehend what your mechanic is doing for your auto then you definitely can hit the web to search for details in regards to building an electric car or truck. While using many sites the functions this phenomenon then it’s going to also be a breeze for you to learn the guidelines and fine points of converting an electric powered auto.

Increasing Value Of Electric Cars
June 1st, 2010
Many more celebrities like Al Gore, Rick Wagoner, Tom Friedman, our President Elect, Barack Obama, are all heavily favoring and supporting a wholesale changeover from fossil fuel driven cars to electrically powered automobiles.
Their faith is based on the Lithium Ion battery. These batteries are very expensive, are heavy, must be replaced after several years, and require hours for recharging. Lithium is not widely available in the US and must be imported.
The performance of Electric car is admirable. They are very quiet, do not emit greenhouse gases directly,can be designed to accelerate well. Electric cars are considered by many as the secret weapon that will reduce our dependence on imported petroleum and will lessen our payments to oil producing countries.
In a good year, US citizens will buy roughly 15 million cars to replenish and grow the US inventory of nearly 250 million used cars. To replace most of this inventory with new models, It may take anywhere from twelve to fifteen years. Initially to stay on top of performance and warranty issues, The Volt, the first electric car produced by General Motors, will likely be leased in small numbers. We can assume that GM and other car companies will sell more than 2.5 million electric cars during the next ten years, optimistically. Replacing 250 million cars will take a few decades longer.
At the same time the US is looking at a population growth of another 100 million residents during the next fifty years. Under the most optimistic assumptions we can expect to in the long run see 150 million electric cars and 150 million liquid fuel powered cars in use by 2050.
Rider cars are accountable for only 45% of nowadays liquid fuel consumption. Under the most favorable conditions and assumptions, electric cars may be able to save 25% of petroleum imports eventually. Liquid fuel consumption for other uses will certainly increase during this time. Optimistically, we may expect that electric cars can cut liquid fuel consumption by 20% in 2050.
