Tech Buisness[1]

  1. 1. Why take the pain to find a electric outlet to charge your phones…Wake up and use solar phones !!<br />
  2. 2. Why use them ??<br />How many times have you run out of battery when you are doing something important?<br />
  3. 3. Solar phones<br />Scientists and technology engineers are working hard to find new ways to power cell phones. As phone batteries have started to drain away more and more quickly (due to more advanced use of phones) these researchers have started looking at a variety of new ways to charge cell phones. Those scientists who are eco-conscious have been looking at how to harness the power of the sun to charge mobile phones. Their hard work is starting to pay off; there are now quite a few options for solar power when it comes to cell phones. They range in size from solar panels on handsets to mid-sized backpack charging devices to solar cell towers…This is how the thought of making solar phones came into existence…<br />
  4. 4. PORTABLE SOLAR CHARGER<br />For a portable solar charger being used to charge small devices, you can get one that has an internal battery. With an internal battery the sun’s energy gets stored in the solar charger itself, and you can then charge your devices when you need to even if it is dark, or it is a stormy, cloudy day, and it usually charges the device quite quickly. Some of these solar chargers can get away with having only a 1 watt solar panel which is a cheaper option, and which would probably not be powerful enough to charge a device, but would charge the internal battery which would then in turn be powerful enough to charge your devices. On the downside, the internal battery will probably need to be replaced after a couple of years and is not environmentally friendly. You may also find that you have purchased a product that has a weak or faulty battery.<br />
  5. 5. Solar chargers<br />Built in High Capacity Lithium Polymer Battery (1350 mAh)Output voltage: 5.0~6.0V Output current: 350~800mA Size:95 x 43 x 12mmCharging Time: around 60 minutes (depend on different mobile phone)Full Charging through USB/AC Adaptor: 5 hoursFull Charging through Solar Power: 10-15 hours<br />
  6. 6. Charger controller<br />You might also want to consider getting a charge controller, as this will prevent your devices from over charging, helps to improve the quality of the charge and prevents accidental discharge from the charged battery.<br />
  7. 7. Solar charge controller<br />Features• Microcontroller Control for Fully Intelligent System• Utilizes Serial Mode PWM Control for Maximum Efficiency• Temperature Compensation• Digital LED Indicator Light• Wide Temperature Working Range of -35c to 50c• No Adjustable Resistance• Full Installation Instructions Included<br />
  8. 8. The worlds first solar cell phone<br />Hitech wealth telecommunications has just begun selling the S116 and the specs are pretty impressive. However, the $510 pricetag will have you wondering why you don&apos;t just get an iPhone. A 1.3 mpx camera, and an MP3 player are fairly standard additions to cell phones these days, but the solar panels do make this guy stand out.The panels trickle-charge the battery in any amount of light, including indoors (or even by candlelight), and the battery life is 2.5 times longer than it would without the panels. An hour of direct sunlight will give users 40 extra minutes of talk time. While this first model is pretty exciting, HiTech Wealth will be releasing six more solar phones within the year and has promised 30 solar models before 2009<br />
  9. 9. They are Affordable<br />
  11. 11. Solar water proof phone <br />Find yourself with a water-soaked low-battery phone? Sharp and Japanese network KDDI have a solution: the world&apos;s first solar-powered waterproof cell phone. The phone, scheduled for a June release in Japan, can nab one minute of talk time or two hours of standby power from ten minutes of sun. The phone can derive 80% of its charge in total from solar power. It&apos;s not a fast enough charging time to change anyone&apos;s life, but it&apos;s ideal for afternoons in the park or on the beach.<br />Samsung&apos;s Blue Earth phone is made from recycled plastic bottles and features a built-in pedometer that  calculates savings on carbon emissions from walking versus driving in a car. The phone will be released in the U.K. some time during the second half of 2009. LG&apos;s solar model works a bit faster than Sharp&apos;s--10 minutes of sunlight provides enough power for three minutes of talk time--but the company hasn&apos;t yet hinted at a release date. The most exciting development in sustainable cell phones may not be solar at all. Kyocera&apos;s kinetic energy-powered concept phone features a fold-out OLED screen that&apos;s big enough for movie-watching. <br />
