Energy doors by moses dhilip kumar


Energy Doors – as the name suggests, doors that can produce electricity. The input is the human energy. The electricity produced can be stored in a battery or can be used directly to provide power to small electrical appliances.
There are two types of energy doors:
1.      Mechanical Energy Doors
2.      Electronic Energy Doors.
The energy door which has gears, flywheels, and an alternator is called mechanical energy doors. The energy door which has lightning piezoelectric components is called as electronic energy doors.
Mechanical Energy doors can be used in public places to produce electricity and electronic energy doors can be used in private buildings, as they produce more electricity than mechanical systems.
The door is connected to a mechanism which has either mechanical components or electronic components. When the door is opened or closed, the given human power, which causes the mechanical motion, is converted into electricity by the alternator or lightning piezoelectric component.
This energy door can be mainly used for powering lighting system using LED’s as they require only small amount of electricity. This reduces the electricity bill and mainly, it reduces the usage of fossil fuels used to produce electricity which cause pollution to the environment.
The main aim of the energy door is to save the environment by providing power using freely available human power without causing any pollution to the environment.

Energy doors can produce electricity by converting small amounts of human energy into electricity. The electricity produced by the energy door can be used to power small electric devices or can be stored in a battery to use it later.

Every building in this world has doors. We humans operate the door using our energy. The door has two operations – open and close. The idea is to add another operation to the door to produce electricity, which utilizes the same human energy to produce electricity. keratuer-modern-entry-door-exclusivline.jpg


The energy door consists of the following parts:
1.     Ordinary door.
2.     Gear wheels.
3.     Flywheel.
4.     Connecting rod.
5.     Chain & Sprocket.
6.     Generator.
7.     Piezoelectric device.
8.     Battery.





1. DOOR:
The door can be of three types:
A.    Swinging door.
B.    Sliding door.
C.     Rotating door.

A.    Swing door is a simple door. In this, the door is connected to a mechanism by a connecting rod which is connected to a chain. The other end is attached with a sprocket which converts the sliding mechanism into rotating mechanism.  The sprocket is connected to gear wheels, which increases the speed of the rotating motion. The gear wheels are connected to a flywheel. The main use of a flywheel here is to make things easier. A slight force is enough from us; rest of the necessary force is provided by the flywheel.

B.    Sliding door – also has the same mechanism as the swinging door.

C.     Rotating door – In this there is no need of converting sliding motion into rotating motion. The gears and flywheel are connected directly to the main shaft of the door. The alternator or lightning piezoelectric component is also attached directly to the main shaft.

Instead of using gears, flywheels & alternators to produce electricity. A piezoelectric component can be used to produce large amount electricity depending on the type of piezoelectric component.
Here, a Lightning piezoelectric component is used. This piezoelectric component is a special type which can produce more electricity when compared to ordinary piezoelectric materials. This lightning piezoelectric component is developed by NASA.
It works on a simple principle. A thin ceramic piezoelectric wafer is sandwiched between an aluminum sheet and a steel sheet and held together with LaRC-SI, an amorphous thermo­plastic adhesive with special properties created by NASA. The sandwich is heated in an autoclave, and the adhesive melts. When the sandwich cools, the adhe­sive bonds the parts together into one piezoelectric ele­ment. While they cool, the components of the element contract at different rates, since they are made of different materials. This differential shrinkage causes the element to warp in either a convex or concave shape, depending on which way it is oriented. The shrinking of the outside metal layers places the inside piezoelectric ceramic under mechanical stress. If the element is cantilevered by clamp­ing one side and then plucked, it reverberates like a diving board that has just ejected a diver.
This way, a small amount of mechanical energy can result in a relatively long period of electrical generation
Lightning piezoelectric component

The working procedure is simple. In swinging & sliding doors, the sliding motion is converted into rotating motion, which drives the alternator to produce electricity. In rotating doors, directly the rotating motion is converted into electricity.
Instead of using mechanical components, piezoelectric component can be used. In this the mechanical energy is directly converted into electricity with much more efficiently than the alternator.

·        The energy doors can be used in public places like hotels, shops, railway station, airport and in many public places.


·        It can be used in private buildings in places like air-conditioned rooms like computer labs, library & etc…
·        A piezoelectric energy doors can be best used in houses which produces larger amount of electricity.

·        The electricity generated by the energy door can be used stored or can be used to power LED lights which needs only small amount of electricity.
·        It can be used to directly power a camera in a door or for an electronic lock.
·        At last, but not the least, it reduces the pollution produced by fossil fuels for generating electricity to a little extent.
The Energy doors will revolutionize the design of doors. Usage of many energy doors in a building can produce large amount of energy which can be used for powering the entire lighting systems, which reduces the electricity bill. And it has many other benefits than conventional doors.
