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.
The watt (W) is the SI unit of power, equal to one joule of energy per second. A typical household incandescent light bulb uses electrical energy at a rate of 25 to 100 watts.
Carbon dioxide and other air pollution collects in the atmosphere trapping the sun's heat causing the planet to warm up. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce over 2.5 billion tons every year.
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.
