The inDOOR Energy Harvester is a low cost, low profile mechanism that converts rotational kinetic energy from opening and closing a door to usable electricity.
It contains a circuit to store this electricity, measure what is produced and dynamically graph and monitor its progress from a website.
The stored electricity can them then be used for any of the buildings off grid needs, such as emergency sign-age, cameras or lighting.



A joule is the SI unit of energy measuring heat, electricity and mechanical work.
One joule is the work done, or energy expended, by a force of one newton moving one meter.

This system is currently in the prototyping and testing phase.
