Uses

Pros-

• This device provides electricity absolutely free.
• Uses no fuel and has no emissions.
• Is very cheap to make and can be started by a push of your hand.
• Can deliver electricity to any device.
• Can switch on and off automatically.
• Can be up graded and be made much much powerful.
• Is good for exercise.

Cons-

• It is too heavy and big to carry anywhere.
• Takes to much mechanical energy to work.
• Dosen't produce too much electricity.

REAL LIFE APPLICATIONS...

Is an alternative way to produce electricity. Is eco-friendly as it turns mechanical energy into electrical energy. Bigger versions of these devices could be used in the power plants in the future as it would store energy to a battery, which would then be supplied to other houses. It could also be used as a secondary source of power for example -  when the power fails in your house and you have to charge your mobile you could connect it to this device and charge it.  

Final Product

Our final design...

We bought a tire and used the chain system in a cycle to create a peddle system to rotate the wheel. The wheel is then connected to a dynamo directly. When the wheel moves the magnet in the dynamo rotates    creating electricity which is then picked up by copper wire and sent to a switch. The switch basically broke and connected the electricity circuit hence it could switch off or switch onn the bulb that was powered by the dynamo. The switch was then connected to the bulb which received power from the dynamo. To hold all of this we made a stand by welding metal.

The paddle system -

The dynamo directly connected to the wheel and with copper wire coming out at the end which supplies power to the bulb-

The copper wire connecting the switch and the bulb-

We added a NXT motor to show that this device could be stopped and started automatically. So what we basically did was that a motor was placed next to the switch. A timer was set for the motor to go off and on, so when the timer went off the motor started clockwise rotation and switched of the motor. The benefit of this was that if this device was used in the theatre industry and there was a stage show going on and you wanted all the lights to go off at a particular time the motor would switch them off.  

Planning and Reflection for Tech Fair

Aim-The aim for our Tech Fare project was to create a cycle generator that produced energy.

Features-The generator would turn mechanical energy to electrical energy and it would also switch off when the timer of the NXT motor runs out.

How we made it?

We gathered all the following materials.We made a stand by welding metal.We then attached a wheel to the stand.We took out a chain system from a cycle and added a pully that would allow us to rotate it.We added a dynamo connecting to the wheel. So when the wheel rotates the dynamo rotates  producing electricity and powering the bulb.We added a switch to start and stop the bulb.We added a motor next to the switch and connected it to a next programmer. This would then start and stop the motor when the timer in the nxt runs out.

I think we were successful as we were able to make it as we planned it and it worked properly.
