man power: a great alternative - energy storage devices

Can stairs capture energy from people walking up and down, store it as electricity, and use it for lighting?
It sounds like science fiction, but it's one of the many seemingly distant novels.
Scientists and engineers take these ideas very seriously and their goal is to use the power generation capacity of the human body.
"When we walked along the sidewalk, we wasted 8 watts of energy --
Absorbed by the ground-with each heel.
However, at least some of the energy is likely to be harvested, "explained Claire Price, director of facilities Architects in London.
"Think about the dance floor, which is designed to suppress vibration and limit the damage that dancers do to the limbs.
What we are working on now is an energy harvester matrix located under the floor.
These suppress vibration, but store rather than consume energy to provide a source of powerfor free.
"Price is leading the Pacesetters project, which will install the world's first human energy collection staircase at the Grand triangle Sail Tower in Portsmouth at the beginning of the new year.
Teams from Philips Electronics and Hull University also attended the meeting
It has a heel.
Strike generator suitable for shoes to capture the energy we apply while walking
The University of Southampton has developed a method for generating electricity from naturally occurring vibrations within buildings.
Their aim is to demonstrate how the human movement generates electricity and to demonstrate its potential to supplement electricity supply in public spaces.
"How to best store the harvested energy is a challenge," Price admits . ".
"Our focus is on improving super-
Capacitors and other storage devices.
However, we believe that if the use of energy is close to where it is generated, these plans will be a viable alternative to the state grid.
It can power the lighting, LED display and audio system used in public places.
"When you consider that a busy traffic interchange like London's Victoria station is estimated to have 34,000 pedestrians per hour during peak hours, the sidewalk sounds like a viable alternative energy source.
There is also a potential green benefit: less copper and plastic are needed once the appliance no longer needs to be connected to the grid.
So, if human energy has this potential, why haven't it been properly utilized before?
Free Game Executive chairman Rory Steer developed the first wind
British inventor Trevor Bellis explained by up radio, who dreamed of it more than 10 years ago.
"The energy generated by human activities needs not only to be used effectively, but also to be stored and released efficiently in a controlled manner," he said . ".
"In order to produce even modest forces, a great deal of human effort is required.
How long does someone prepare to work to store the energy of a particular product?
However, due to the lower power consumption of designed electrical products, potential applications are also growing.
"This is the kick now-

Power generation.
More and more low
There are power products now.
Progress has been made in understanding how to capture, store and release human energy.
Professor Neil White of the University of Southampton pointed out that the Pacesetters project was not the first attempt to utilize human energy, and he developed a device that could take energy from the vibration of the building.
"Back in her 80 s, Seiko developed a dynamic watch powered by human movement.
"This eliminates the need for conventional batteries by using the distance that the human arm can cover over time," he said . ".
"Since then, many dynamic watches have been produced, but the potential of this technology to power larger appliances is limited by the low speed of people moving.
"The US and British forces have tried Energy --
A harvesting device that can be built into a soldier's boot.
An application of this technology is to supply power to wireless phones traditionally powered by bulky rechargeable batteries.
However, the plan failed when it became clear that the Harvester was not strong enough to withstand extreme conditions.
Then in the early 90 s, with the wind, the free game appeared
Radio, lights and flashlights.
Recently, it invented a wind.
Mobile phone charging generator, 1 feet-
Pump generators capable of powering larger projects and prototype series of wind power
Medical equipment.
It is also involved in the development of wind power.
Mechanism for powering so-called $100 (£53)laptop -
It is being developed in order to bring personal computers to children throughout the developing world.
There are different opinions about what is the best way to use manpower.
For some, the future lies in building
In equipment such as heel
Strike generator;
Others have pointed out that the mechanisms that can utilize the energy generated by human joint activities.
The Pacesetters project has attracted the attention of the business community, Price said.
She is working with a fitness equipment manufacturer to develop a way to take advantage of the power generated by people using treadmills.
Meanwhile, Steer has reached an agreement to launch renewable energy. energy-
Power products in India.
However, he believes that the future of free games is to develop products that combine wind energy.
Solar and wind power technologies.
"Sustainable energy is a niche business in developed countries and may always be --
"Legislation encourages its development, except in the UK," he explained . ".
"The reason is simple: ordinary consumers want the easiest access to energy --
State Grid.
The story so far. . .
Seiko launched the first
The battery watch was powered by the wearer's movement in 1988.
Its range of motion uses the oscillating weight to rotate through the movement of the wearer's wrist, which is converted into magnetic charges and then into electricity, stored in a miniature capacitor and rechargeable battery.
MIT's MIT Media Lab is one of many institutions to explore the potential of devices embedded in shoes to generate energy while the wearer walks or even takes energy from finger movements.
Possible down-to-earth applications include powering a radio or wearable computer.
Earlier this year, the Japanese railway company East Japan Railway Company installed the wicket to generate electricity through the shock and pressure generated by people during the wicket.
Electricity is used to operate automatic gates.
Freeplay developed and manufactured the original wind
Radio invented by Trevor baylisss
Since then, it has developed a whole family. up radios;
Branch wind-
Torch and hybrid products using solar and wind energyup power;
Recently launched Weza, its first footpump generator.
The future application plan of its technology includes
Medical devices generated.
Researchers at Georgia Institute of Technology have shown that cheap Naimi lines can be used to get mechanical energy from inside the human body.
This can be used to drive advanced medical implants.
