Making a device that transfer energy.

Ideas:

– A device using kinetic energy and turning it into electric or other energy

– A toy

– Maybe include the use of renewable energy

Purpose:

  • Educational
  • Understand / shows the process of energy transfer

Users:

  • Children or anyone

Precedents:

  • Wireless Power Transmission –

This device conduct electric without wires and simply to use and create. It can be use to light a bulb etc.; however, it

Does not transfer energy from one to another and can only conduct electric.

Pros: Simple to make if have all the materials. Its connecting the wire with all the resistor, transistor and the led together, and by changing the distance between will allow the led to light.

Cons: It requires specific materials such as 27k resistor, 2N2222A transistor that will make it work.

  • Music box

It uses kinetic energy by turning the handle and stores elastic potential energy. The energy is then transfer  into sound energy.

Pros: Theres lot of different transfers of energy in this device and be able to see the process of energy transferring,

Cons: It might be difficult to make the core parts inside and needs to make it able to see in side.

  • Solar hand-crank generator lamp

A lamp light by giving it mechanical energy by turning the handle, The mechanical energy is then transfer into electric energy, then is transfer into light energy to come out. Thermal energy will also be transfer as a waste energy.

Pros: It shows various type of energy transfer.

Cons: It might be hard to make and design.

  • Solar mobile charger

This is a device that use solar energy and transfer it into electric energy to charge the phone.

Pros: It’s using renewable and also can charge a phone.  It’s simple to create with all the material needed.

Cons: It requires sun to work and material used are all pretty specific.

  • Popper toys

Rhode Island Novelty 2" Poppers- Buy Online in Qatar at qatar.desertcart.com. ProductId : 17500548.

This is a toy which when bend in, will give it elastic energy and when release the energy will transfer into kinetic energy as it pop up. As it is in the air, kinetic energy will then turns into gravitational potential energy as it reach the highest. When it drop down, the energy transfer back into kinetic energy.

Pros: It shows energy transfer through playing this toy and easy to make.
