In this write-up we present a brief background on batteries and battery chargers to introduce you to the much more recent and environmentally friendly technology associated with solar battery chargers. We also present examples of various battery chargers that use solar energy.
Batteries had been invented around 1800. A battery combines 1 or much more electrochemical cells which store energy. This energy can then be changed into kinetic energy so as to produce electricity. Batteries have turn into so ubiquitous that we rarely think about how central they're to daily life. We use batteries in flashlights, watches, cameras, laptop computers etc. Batteries can be found within the dwelling and in company. Makers of batteries incorporate Energizer and Duracell plus the battery business generates billions of dollars in revenue.
Unfortunately, until the late 20th century batteries were disposable and sat in landfills where they leaked toxic chemicals. To be able to alleviate environmental harm and to minimize the price of buying single use batteries, battery chargers came to market.
Battery chargers put energy into a rechargeable battery by transferring a current by means of it. The current's charge varies depending upon the technologies and size of the battery. For example, we use unique rechargeable batteries and chargers for laptops than we do for golf carts. Because of the widespread use of nickel cadmium high-power batteries that power electronics which include digital cameras, battery chargers have turn into a lot more well-known; they are able to now be discovered in practically any electronics store. The demand for chargers has even has stores like CVS, Target, and Wal-Mart selling them.
According to Energy Star, a government program that promotes energy efficiency, about 230 million merchandise use battery charging systems in American homes and businesses. Energy Star promotes energy-efficient battery chargers and estimates that Americans could save over 1,000,000,000 kilowatt hours of energy per year if they utilized far more efficient chargers.
Promoters of solar chargers point out that even far more energy could be saved if the sun's power is harnessed to recharge batteries: battery chargers may also use solar energy to force an electric current into the battery. As the market for solar items have grown, we have seen corresponding growth within the solar battery charger marketplace.
Following are some examples of distinct chargers that use solar energy:
??? Solar digital camera battery chargers. Although camera producers may perhaps not sell OEM solar chargers, you'll be able to buy third-party chargers for brands for example Nikon, Olympus, Panasonic, Sharp, and Sony. When shopping for a solar charger for your camera, check to see how many volts your camera battery is. Then it is possible to order a corresponding solar panel to charge it. Prices for a battery charger for a Sony digital camera range from approximately $140 to approximately $250.
Solar chargers for cell phones and iPods. You can maintain little devices including a PDA, iPod, or cell phone running with a solar charger. Solio makes a pocket-sized charger that will charge the Apple iPod, iPod mini, iPod nano and PDAs. Costs begin at approximately $100.
Other items that use solar chargers consist of photovoltaic backpacks, hearing aid batteries, and laptops.
For anyone who is committed to lowering your carbon footprint, then invest in a solar battery charger for electronic devices that you use all of the time.
