The document describes a device called "Walk N Charge" that uses a dynamo to convert the kinetic energy from walking into electrical energy to charge low-power devices. As the user walks, the dynamo attached to their leg spins and generates 3.5 watts of power with each stride, enough to slowly charge a mobile phone battery with 20 minutes of intermittent walking. The device has advantages like being portable, renewable, and allowing charging anywhere without other power sources. It could help provide charging in rural areas and for military personnel on the move while reducing carbon emissions.

CONTANTS INTRODUCTION FLOW OF OPERATION WORKING ARRANGEMENT PROS & CONS ADVANTAGE FUTURE PROSPRCTIVE CLOSING STATEMENT CONCLUSION
INTRODUCTION Walk n Charge is one of the latest technologies used to charge the low power device like Mobile batteries, MP3 player Batteries, Power Bank etc. Two technologies are used to convert energy used in Walking into Electrical Power i. By Using Piezoelectric material. ii. By Using small Electro Mechanical Devices (Dynamo).
By Using Pizeoelectric This gets compressed while you walk and generates a substantial voltage, which when combined with appropriate electronics, can be used to charge a mobile phone battery. The piezoelectric device generates about 150 milliwatts of power as of now, which is not sufficient to run a cell phone, but would be enough to charge the battery slowly. By using Small Electro Mechanical device(Dynamo) It involves placing small electro-mechanical devices, such as a dynamo, in the heel of the shoe. The dynamo spins every time your heel strikes the ground, thereby generating a small amount of current. The dynamo technology has the potential of generating much more power than piezoelectric material
FLOW OF OPERATION While walking rack rotates the pinion (Rack and Pinion mechanism) Pinion rotates the Dynamo (ME to EE) Electrical energy is obtained from dynamo The electrical energy is stored in Rechargeable Battery Can be consumed at any time of the day
WORKING:- Work n Charge is worn below the knee cap on one leg and a light string is attached to the other leg. The strides taken help in pulling and retracting the string, which is further attached to a dynamo that generates about 3.5 Watts; enough to charge low-powered devices like mobiles, MP3 players, GPS devices, etc Walk-N-Charge is about converting a part of the bio-mechanical energy spent in our day-to-day lives (while walking) into a usable form and storing it to charge low-power battery-operated devices. Walking involves a change in relative displacement of around 35 cm between legs. This repeated linear motion could be converted to rotary motion with the help of a pulley and string. Thus, the bio-mechanical work is converted into mechanical form and eventually stored as chemical energy in batteries to store electric energy.
ARRANGEMENT:- The device is clamped on one leg using a Velcro strap and a hole lets out a Nylon string that is attached to the other leg that helps in the conversion of the displacement into rotary motion.
EACH WALK-N-CHARGE IS CAPABLE OF GENERATING MINIMUM 3.5 WATTS OF POWER AT NORMAL WALKING SPEED (4 KM/H). AN INTERMITTENT WALK OF 20 MINUTES IS SUFFICIENT TO CHARGE A MOBILE WITH AROUND 1 HOUR TALK TIME, WHICH CAN BE CONSIDERED AS AN AVERAGE PERSONS PHONE USAGE FOR A DAY. FOR A PERSON WITH AN AVERAGE WALKING OF HALF AN HOUR PER DAY, THIS DEVICE CAN GENERATE 2 W/H OF ENERGY.
PROS AND CONS: PROS:- Eco-friendly Portable Can be charged at any time without any power source Compact Renewable Economical CONS:- Wear of gear teeth will affect voltage production No water-proof
ADVANTAGES/APPLICATION:- Increasing the effectiveness of mobiles in rural india by providing a portable means of charging of mobiles,torches,radios. Helping military personnel charge their GPS devices and other low-power electronic gadgets while on the move.
FUTURE PROSPECTIVES:- India has signed the Kyoto Protocol - an acknowledgement that we share the concern of global warming, which also expresses our commitment to slow down climate change. Walk-N-Charge would just add to the efforts put in by India in various innovative ways.
CLOSING STATEMENT:- This technique of charging helps us to use the renewable energy from human movement. We can consume electricity without worrying about power shutdown.
CONCLUSION:- Hence, walk-n-charge is the best idea for battery charging. Even if 0.1% of the Indian population uses this device, it can generate 1500 kW/h of energy and can help reduce carbon emission by 2.25 tonnes per day. Thus, Walk-N-Charge promises you a source of energy that is not only clean, portable and inexpensive, but also charges your mobile while you get charged up!
