A new aerodynamic device has the potential to reduce the energy consumption of supermarket refrigerators by up to 41.5 percent. The product, currently being developed by Williams Advanced Engineering in collaboration with Aerofoil Energy, can be clipped onto existing cabinets, making it easy for companies to upgrade their stores.  Read More

Office buildings with plate glass windows may provide a nice view for workers, but they're certainly not ideal when it comes to energy-efficiency. Among other things, the sunlight that pours through them can raise the temperature in the office, causing the air conditioning to come on. Now, however, researchers from Germany's Fraunhofer Institute for Machine Tools and Forming Technology have created a light-blocking facade for such windows that only kicks in when exposed to strong sunlight – and it's powered by that sunlight, too.  Read More

It's a simple fact that the more fluid an oil is, the easier it is to pump. That's why oil companies typically heat sections of pipeline, to reduce the viscosity of the crude oil traveling within. Generating that heat still requires a fair amount of energy, however, plus the oil's reduced viscosity produces turbulence it its flow. Temple University's Prof. Rongjia Tao has developed what may be a better alternative – a device that electrifies the oil.  Read More

If you're trying to save power, you generally don't leave your lights on all night. With a few exceptions, however, that's what cities do with their streetlights. That's why some groups have developed streetlights with built-in solar panels. A Spanish team is now taking things a step farther, with a stand-alone streetlight that runs off of both solar and wind power.  Read More

Fraunhofer's solar-powered radio sensor chip, mounted in a window

Although it may be handy to have sensors in your windows that remind you if you've left them open, running electrical wiring to all those sensors (or regularly changing their batteries) could be a hassle. A new window-monitoring radio sensor chip, however, gets all the power it needs from the sun.  Read More

The Miito is an induction kettle that heats only the liquid you need (Photo: Miito)

We all know that you should boil only what you need in a kettle to avoid wasting energy, but overfilling is still very common. The Miito combats this problem by using induction heating to boil just the water you need.  Read More

Chisel allows small computational errors to be made, in the name of saving power (Image: S...

You may have heard the expression, "Work smarter, not harder." When applied to humans, it means (partially) that we should do our best work on the tasks that are the most important, instead of wasting time and effort by going all out on every task. Well, that principle is now also being applied to computers. Using MIT's new Chisel system, computers are saving power by delegating less-critical tasks to less-dependable lower-energy hardware. This means mistakes may be made on those tasks, but that's OK.  Read More

The as-yet-unnamed building is due to be completed in 2016 (Image: Studio Gang Architects)

Chicago-based Studio Gang Architects has unveiled some early renders and a few preliminary details concerning a new, as-yet-unnamed, residential tower slated for Miami. The firm is targeting LEED Gold certification for the project.  Read More

The EcoDrain uses outgoing hot water to heat incoming cold water

Generally-speaking, when there's something that we're trying to conserve, we don't just put it down the drain. For those of us who are trying to save power, however, that's just what happens when we let hot water from our showers or baths run straight into the sewer. The EcoDrain is made to address that problem, via a unique design that allows outgoing hot water to warm up incoming cold water.  Read More

Honeywell has announced the Lyric smart thermostat

Honeywell has announced a new thermostat, Lyric, that tracks the user's location via their smartphone and adjusts the temperature of their home accordingly. It figures out when a household is empty and when residents are on their way home. Users can expect reduced energy usage and costs.  Read More
