A small, low-cost wind generator that produces electricity

A small, low-cost wind generator allows you to produce electricity from the smallest breeze.

Capture a low cost wind generator converts light wind into electricity

The wind harvester, developed by researchers at Nanyang Technological University, is a small, low-cost wind generator.

The device is designed to capture light winds such as city breezes and convert them into electricity that can be used to charge electronic devices or batteries.

It can output a voltage of three volts and generate electricity of up to 290 microwatts when exposed to wind speeds as low as 2 m/s. Enough numbers to trigger a sensor and send data to a mobile phone or computer.

It can even convert unused electricity into a battery, where it can be stored to power appliances when there is no wind.

Wind harvester features

a team Nanyang Technological University He claims that the device, which measures just 15 by 20 cm, can be easily mounted on the sides of buildings and would be ideal for urban environments where average wind speeds are less than 2.5 m/s, except during thunderstorms.

The body of this generator is made of epoxy fibers, a very durable polymer, with the main accessory that reacts to the wind and is made of cheap materials such as copper, aluminum foil and Polytetrafluoroethylenewhich is a durable polymer also known as Teflon.

The generator, when exposed to the wind, begins to vibrate, causing its plate to close in and away from the cap. This causes charges to build up on the foil, resulting in an electric current passing from the aluminum foil to the copper foil.

In laboratory tests, the wind generator was developed by continuously powered LED lights, at which time a wind speed of 4m/s was measured. It can also activate and operate a sensor enough to send ambient temperature information to a mobile device.

The researchers say their invention has the potential to replace batteries in providing light-emitting diode (LED) lights and sensors for monitoring the structural health of buildings.

These are used to monitor the structural health of infrastructure or buildings, and to alert engineers to problems such as instability or physical damage in urban constructions such as skyscrapers and bridges.

The purpose of a small wind generator

As a renewable and clean energy source, wind energy is attracting more and more innovative projects.

This research came to fill the gap from a small-scale power generator to more specific functions, such as providing power to sensors and smaller electronic devices.

This device also serves as a potential alternative to smaller lithium-ion batteries, since it is self-sufficient and will only require occasional maintenance, and does not contain heavy metals in its composition, which, if not disposed of properly, can cause environmental problems.

The research team is already working on the next step for the wind harvester, which is to improve storage functionality. or other materials that can improve energy output.
