A smartphone addict's peace of mind is directly related to the power of his or her device's batteries. As long as the bars are full, techies are happy and content. However, all hell breaks loose when the stored power enters 10 percent remaining territory.
Their dilemma becomes even graver when there is no power socket to plug in their chargers. For such conundrums, engineers around the world are busy finding alternative solutions, some of which are listed down below:
Starbucks' Wireless Charging Mats
Coffee chain company Starbucks has teamed up with Duracell Powermat to add wireless charging mats to its coffee tables. The visiting customers can get their batteries replenished by simply placing their phones on the mat.
Shoes That Produce Electricity and Charge Phones
Just last week, a Filipino teen hit the airwaves for successfully developing a pair of shoes that generates electricity, which can then be used to charge smartphones and other similar devices.
The Hand- Crank Charger
Eton is a company that specializes in hand-cranked emergency devices. One of their coolest tech offerings is a hand-crank mobile phone charger, which they call BoostTurbine 2000. A minute of nonstop rotations on the charger's crankshaft would give you 30 seconds of talk time on the phone. You'll never have to look for a power socket again, and the forearm muscles could soon develop into something like Popeye's.
The Wind Turbine Charger
Tired of his phone running out of juice every day, Dutch designer Tjeerd Veenhoven came up with the idea of making a mini wind turbine to refill his batteries with green power. By simply using a computer fan and making a few minor modifications, Veenhoven came up with the device he calls iFan. It takes six hours to charge a normal sized battery, but you can have the satisfaction of knowing that nature powered it.
The Fire-Side Charger
This here is an outdoor device called BioLite CampStove, which does everything that a normal outdoor stove does, and then some. In addition to roasting marshmallows, it uses the heat from campfire to produce electricity, which can then be used to charge your phones via a USB port. The idea of plugging your phone into a machine that has fire coming out of it may not be the wisest thing, but don't say you didn't have the option to do it.
When on the lookout for power, why not dip into the most massive reserve of energy in the solar system? The Sun regularly emits 400 trillion trillion watts, and the Solio BOLT Solar Charger gives you an option to use that energy to charge your smartphone.
Last year, scientists at the Bristol Robotics Laboratory successfully demonstrated the use of human urine as a source to power mobile phone batteries. That may sound disgusting, but the solution it offers outweighs the disgusting bit by a factor of 10. At least it does in our opinion.
