REsearch on kinetic energy

The kinetic energy of an object is the extra energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its current velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Negative work of the same magnitude would be required to return the body to a state of rest from that velocity.

Kinetic energy to power something:
Benefits:
• Minimize number of charged batteries needed to be carried around
• Usage of regenerative energy instead of non-regenerative energy
• Charge-up your batteries while on the move
• No need to sit by charger to wait for battery to be charged

Features:
• Portable design
• Environmental friendly
• Efficient power-charging method
• Revolutionize the way we think about charging batteries

Electromagnetic generator ----------> Step up transformer -----------> Rectifier -------------> Regulator


Electromagnetic generator – This block is made up of bar magnets moving in a copper coil inducing electromagnetic power. Due to the movements of the user, the magnets will swing in and out of the wire coils and will therefore induce the generation of voltage in the coils. The generated voltage will then be harvested via wires connected to the coils. The harvested energy from this block will be transferred to the Step-up Transformer component.

Step-up Transformer – This block is made up of wires coiled around metal bars. The primary coil will have fewer coils than the secondary coil. The fraction of coil difference will be determined after a consistent output from generator is obtained. The transformer will receive the output of the generator and step it up to the optimum output that we require for the battery. The output voltage will then be used to power the recharging process.

Rectifier – This circuit is built to convert the electrical output from the transformer from AC to DC in order to charge the batteries. This circuit will mainly consist of diodes in certain arrangement to regulate the current flow in one direction.

Regulator – This circuit is built to ensure that there is no voltage spike and ensure that the power supply remains constant. By using a component like a Zener diode, we could regulate the voltage supplied to the charging device without spoiling it. It also ensures that the power stored in the battery does not leak back into the device.

Generator – We will test the output of the generator to ensure that we can get a decent voltage output from a small movement and also from a vigorous shaking. We will measure the voltage and current output so as to know the range of power that we will be dealing with.

Transformer – We can test this by inputting a voltage from a function generator and then measuring the output of the transformer via an oscilloscope or voltmeter. From the ratio of the output voltage versus input voltage, we can verify whether the generator is working as planned.

Rectifier – We can test this circuit by using a function generator to supply an AC voltage current to the rectifier circuit and then measuring the output of the circuit to see if it is in DC voltage. We will also have to minimize the ripple of the output.

Regulator – This circuit can be tested by sending in a range of voltages using a function generator and checking the output of the circuit on an oscilloscope. When the voltages are above or below the designated voltage range of the device, the output of this circuit should be zero volts.



DUE TO INEXPERIENCE I TOOK MOST OF IT FROM AN EXPERIENCED TEAM ON THE INTERNET BUT IT APPLIES THE SAME TO OUR PROJECT. I DIGESTED THE INFORMATION AND ADDED THE APPROPRIATE INFORMATION FOR THE CHEAPEST AND BEST PLAN.
