Power from the Subway

Power from the subway

Many of us who use public transportation such as trains at some point or other have experienced the sudden gush of air when a train enters the tunnel. But Singularity Studio feels creative about this unused air pressure inside the tunnel and they have come up with a new tile prototype which turns this pressure into useful renewable energy. This prototype is named Transducer Tile and does an amazing job converting the pressure into power by a simple mechanism. The modest design is made up from readily available elements. A transducer tile consists of a micro wind turbine. The blade is rotated by the… read more

Living With Wind Farms

Living with Wind Farms

Innovative methods with which to generate energy are important in the fight against global climate change. That is why it is important for authorities to ensure that when these methods are introduced into society, they are well received and thus seamlessly integrated into the communities they are meant to service. Wind energy can be converted to mechanical energy using wind turbines, an alternative energy which lowers greenhouse gas emissions. Generating energy using wind turbines has not been without controversy, it has resulted in a number of lawsuits in some jurisdictions worldwide. The objection to wind farms stems from the noise… read more

Power Your Home by Pedalling Your Bike

spokes

With as little as three essential objects, in addition to yourself,  you can put your strength to good use powering your home and its various contents with your own bike generator. These crucial ingredients include a bike, a motor (a stepper motor, permanent magnet motor, or automobile alternator), and a battery pack. When constructing your own bicycle generator, it is better to use a real bicycle, preferably a road bike, rather than an exercise or stationary bike. Though you will need a stand or bike trainer to keep the bike in a stationary position. Bikes with gears allow people of… read more

Why Modern Lighting Is Bad For A Good Night’s Sleep

Why Modern Lighting Is Bad For A Good Night’s Sleep

When people decorate a room, things like furniture, textures and paint color tend to stand out. However another element that is significant, but possibly overlooked, is the lighting. Proper lighting is a necessity for functionality, but it also has another important use. A recent article in Psychology Today gives a great overview of depression, sleep habits, and how an unexpected culprit, contemporary artificial lighting, comes into play. As humans, we are pre-dispositioned to be active during the day and at rest during hours where there is a lack of natural light. Though our internal rhythmic clock has not completely abandoned… read more

How Much Do Your Appliances Cost You?

Energy Star

Many of us don’t realize that the cost of the appliances we buy doesn’t end after purchase. The power consumed by these appliances will be reflected directly on our electricity bills every month. So next time you buy an electrical appliance you need to consider its energy efficiency. Energy Star, a joint program of the U.S Environmental Protection Agency and the U.S Department of Energy, helps people around the globe to consider the environment and save money by ensuring they only purchase energy efficient products. According to Energy Star, an average home spends over US$2000 on energy usage per year… read more

Home Heating by a Robot

Warm Up Robot

Heating our homes in winter consumes vast amounts of energy and costs households a great deal. But imagine if there were a robot that could store heat and then moved around the house to warm cold areas? Drum roll please for…..Hagent, the mobile heater robot. This small robot shaped like a black box is amde up of movable wheels, sensors and Phase change materials (PCM). PCM  absorb heat from a hot body and change their phase (from solid to liquid or vice versa) and then release the heat by again changing their phase. Designed by Andreas Meinhardt and Daniel Abendrith… read more

Energy Leaks at Home

www.prlog.org

It is widely said that the most expensive part of a building construction is its interior design and architecture. But there is one more important thing to check and that is “energy wastage”. In the US, it’s estimated that billions of dollars are wasted each year because of air seal leaks in doors, walls and windows. Nearly 40% of energy spent on cooling or heating a building is wasted because of this invisible problem. Any small improvements in each building can save the total power of the nation. Leaks in buildings are usually detected by a  “blower door test” which… read more

People Power, Literally

Unplugged Desk

Have you ever wondered what your workspace will look like in the future? The electronic devices at your desk may not be powered by solar energy or other technology. You may become the source of power for your workspace. The thesis project of a Swedish student Eddi Törnberg, titled “Unplugged”, is looking at how to make use of the energy generated by millions of people as they sit and work in the office. It is inspired by Harriet Beecher Stowes quote “Human nature is above all things lazy” so Tornberg has looked at how to ensure all your movements and daily activities are not going to waste,… read more

This Robot Is A Solar Powered Police Officer

This Robot Is A Solar Powered Police Officer

Directing traffic is an occasional part of an officer’s duty, and those who guide vehicles and pedestrians on a regular basis know how frustrating and downright dangerous it can be. Located in Kinshasa, Congo, there is a new line of police officers that are demanding people to stop and take notice. In order to tend to busy traffic routes and decrease financial costs in the African region, an innovative group at the Kinshasa Higher Institute of Applied Techniques has developed a robot that can perform like a traffic officer. The robot can observe traffic flow and works as a stoplight,… read more

Artificial Leaf Nearing Completion

Researchers are close to completing the development of an artificial leaf that could generate hydrogen. The leaf would run on solar power and convert water into hydrogen and oxygen efficiently. The goal of the project is to create a viable renewable energy as part of the BISfuel initiative by the Energy Frontier Research Center — a company funded by the Dept. of Energy. “Initially, our artificial leaf did not work very well, and our diagnostic studies indicated that a step where a fast chemical reaction had to interact with a slow chemical reaction was not efficient,” said ASU chemistry professor… read more
