Energy Doors
You've seen revolving doors in malls, stores, supermarkets, and other places. With all the people pushing through these doors scientist made a way the revolving doors can help produce energy. The energy cycle would go from people, to mechanical, to electrical. Revolving doors uses a kind of energy conversion called piezoelectricity, essentially a technique for converting kinetic energy into electrical. Some revolving door utilizes super capacitors that store the generated energy as a buffer. It provides a consistent supply for the low energy LED lights in the ceiling. With this technology the door will save around 4600 kWh per year in energy, which is about enough to power about five average American households for a month. In the long run this door will hopefully broaden the meaning of alternative energy.

The technology referred to in this article is very inventive and useful in a person's everyday life. If this technology were to be used in a massive urban area, like NYC, it would indefinetly save people millions of dollars in electric bills! This simple conversion of mechanical energy into electrical energy in everyday activities is ingenius and is the type of technology needed to create a more efficient environment in today's world.
This is a really cool technology and is definitely applicable in the future. This kind of technology will no doubt be used in all kinds of things, and, mixed with other conversion technologies such as the stepping floor covertor, we will be able to save alot more energy in everyday life. The only question I have is, why wasn't this done before?
Piezoelectricity, used to convert kinetic energy to electrical energy, is being implemented in the overhaul of the Tokyo subway system. As people pass through the turnstiles, the energy will be collected. This same technology is being used to develop energy collecting roads by incorporating piezoelectric crystals into the road.
