When designing this product, I did intensive research on existing kinetic generators on their pros and cons.

Solidworks semi final model rendering
This is a more user friendly redesign of a bicycle powered generator that uses kinetic energy to create usable electricity. When the user pedals the bicycle the wheel spins the friction drum, therefore powering an alternator. The energy produced is placed into a detachable power pack that can be taken anywhere.
The amount electricity produced can power small appliances.
