With the increase in population in recent years, the average consumption of energy has increased manifold. So, it’s our responsibility to devise and practice energy efficient ways of living. Mobile phones, beyond a doubt, have become an inseparable part of modern lifestyle and they require energy for allowing users to stay connected always. So we should look forward to unconventional ways of charging our gadgets (include cellphones too). Here we’ve listed certain unconventional ways of charging phones without traditional chargers. Read on to know more:

Orange Power Wellies



These willies were designed for people who were going to Glastonbury Festival. Orange in collaboration with GotWind designed these willies with power generating sole. This sole uses the heat from your feet to converts it into electricity. They call this “Welectricity” and can be used to charge mobile phone or any other portable gadget. Twelve hours of stomping on these shoes would charge your mobile phone for an hour. This charger uses a thermocouple to generate electricity with the help of heat.

Nokia concept carbohydrate charger



Designed by Daizi Zheng, the Nokia concept carbohydrate charger provides much cleaner energy as compared to Li-ion batteries. This charger has a fuel cell which utilizes carbohydrates (abundantly present in cold drinks) to produce energy. This carbohydrate fuel cell is three times more powerful than a standard Li-ion battery.

Human dynamo



With resources running out, humans have to think of unconventional ways to generate electricity. Human dynamo captures the movements from your knee and sends it to rotate a dynamo. This dynamo generates usable electricity. Right now the prototype is a bit bulky, but the design can be improved to make a lighter and smaller version. This bio-mechanical energy harvesting device can power-up your phones, iPods and mp3 players.

PowerTrekk



PowerTrekk is an innovative charger made by a Swedish Company, myFC. This pocket sized charger consists of a tray and an eyeglass style cover. If you spend a lot of time away from electricity grid, this gadget can help you out. It would also be great if you are trekking out on a weekend with friends. The container has sodium silicide which, when combines with water, produces hydrogen. So, after pouring one tablespoon of water, you get usable electricity for your cellphone.

Twirling Battery



Twirling battery is another interesting design. It has a slot where you can put in your finger. After inserting a finger, you just have to spin it like car keys. This battery is designed by Song Teaho & Hyejin Lee. Approximately 130 spins would generate enough stand-by for 25 minutes. This battery had also won Greener Gadgets Design Competition in 2010.

Nanogenerator in shoes



Designed by some Argentine designer, this unique charger sits on your shoes. This charger has nano-generator which utilizes kinetic energy in a skater to transform it into electricity. Apart from skateboarding, this device can utilize kinetic energy generated while running and walking. It has a USB port where you can hook up your phone’s cable to start charging.

Charger Bra



A Japanese lingerie maker, Triumph, has made this solar charging bra. This bra has a solar panel which is worn around the waist. This solar panel converts solar energy into electricity, which can be utilized by cellphone and portable devices. You can carry it while going on a beach or where there is a lot of sun. This might have some design issues but it still works.
