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

This Headband May Make You Smarter

This Headband May Make You Smarter

Researchers have figured out a way to “wake up” the brain during learning tasks. A team of psychologists at Vanderbilt University have recently published an article in the Journal of Neuroscience that offers their findings into research which examined prompted electrical currents in the brain and the effects on learning speed. A wearable device resembling a headband was produced for the study, and had an added feature – it can actually make the wearer smarter, even control their learning speed, with the onset of mild electrical stimulation to certain regions. The researchers wanted to further understand the natural response that occurs… read more

Town Planning and Transport Efficiency

Public Transport benefits

In many developed countries public transport is so efficient that many people use it to get to and from work. Besides the economic benefits of using public transport, this choice of daily travel could potentially reduce carbon emissions. In Swaziland the use of public transport to travel to work has not taken root due to the inefficiency of our public transport system. Town planning and transport efficiency in our cities is increasingly becoming important. The way in which our towns are developed will now have to take into account the environmental implications of travel within the city, and also to… 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

Mogees Lets You Be The Musical Artist

Mogees Lets You Be The Musical Artist

If you love music but don’t play an instrument, Mogees have it covered. Bruno Zamborlin, a researcher in musical technology, has developed a device that lets people be musical within their own perimeters. A Kickstarter project soon to come to life, the Mogees system is powered up when plugged into a smartphone’s headphone jack and can be used with iOS or Android apps. The unit, which sort of resembles a bottlecap design, can be placed on any surface. Users open up the app, and the internal sensor picks up on the vibrations that are made when responding to any ordinary… 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
