Energy-saving

A new system that puts smartphones into 'subconscious mode' could boost battery run times ...

University of Michigan researchers have proposed a new power management system for smartphones that could dramatically improve battery life. Working with doctoral student Xinyu Zhang, computer science and engineering professor Kang Shin has created a proof-of-concept system known as E-MiLi, or Energy-Minimizing Idle Listening, that addresses the energy waste that occurs when "sleeping" phones are looking for incoming messages and clear communication channels. For users on the busiest networks, it could extend battery life by up to 54 percent.  Read More

An experimental energy-saving streetlight system automatically dims the lights when no peo...

Of all the energy-saving tips out there, probably the one we hear most often is to not leave lights on when we leave a room. It’s good advice, yet cities around the world are not following it in one key way – their streetlights stay on all night long, even when no one is on the street. The Netherlands’ Delft University of Technology is experimenting with a new streetlight system on its campus, however, in which motion sensor-equipped streetlights dim to 20 percent power when no people or moving vehicles are near them. The system is said to reduce energy consumption and CO2 emissions by up to 80 percent, plus it lowers maintenance costs and reduces light pollution.  Read More

As computers, data centers and mobile devices become more powerful, their energy requirements are likewise generally increasing. Possible solutions to the problem include power-saving sleep modes, devices that keep computers from drawing a current when supposedly turned off, and water-cooled processors. EnerJ, a new solution created at the University of Washington, takes a different approach – it supplies less power to regions of the chip that are performing processes that don’t require absolute precision. In lab simulations, it has already cut power consumption by up to 50 percent, although that amount could potentially reach as high as 90 percent.  Read More

The OnPlug is essentially a single-outlet power bar, that keeps household electric devices...

Call it standby power, phantom power or vampire power, but the current drawn by various household electrical devices when they are supposedly “off” can account for up to ten percent of a home’s energy use. Fortunately, there are gizmos available that act as “middle men” between wall outlets and devices, completely shutting off the power supply when the devices are not in use. One of the newest is the OnPlug, which manages to come in at quite a low price point by avoiding the bells and whistles of similar products.  Read More

Researchers have developed a single 'unified' device that can perform both volatile and no...

A team of researchers from North Carolina State University claim to have created a memory device that could give computer users the speed advantages of DRAM system memory and the data retention capabilities of flash memory, in one unit. The new device could lead to genuine instant-on computing and machines with improved resiliency. The development may even lead to power-hungry server farms making considerable energy savings by allowing parts of the system to be shut down during periods of inactivity without fear of data loss.  Read More

The University of Copenhagen's Prof. Matthew Johnson, inventor of the Cleanair system

According to the University of Copenhagen’s Prof. Matthew Johnson, approximately one-sixth of the energy consumed in the world is used for heating, cooling and dehumidifying air in buildings. Because that air accumulates toxins and pathogens, he explains, it must constantly be expelled and replaced with new air that’s drawn in from outside. That new air must then be heated, cooled and/or dehumidified all over again. If only the air already in buildings could be cleaned up and reused, far less energy would be used on continuously conditioning fresh air. That’s why Johnson has invented the Cleanair system.  Read More

The Eco Switch kettle (Source: SEVERIN)

We've seen several innovations in the design of the humble electric kettle recently that save time and energy – here's another one. The "Eco Switch" kettle has two settings – one for normal boiling water and a second which heats water to 85-degrees Celsius (185F) for things like soup. This means you get your warm water quicker, save energy, and you don't have to wait for it to cool down before you can drink it.  Read More

Reducing your power bill with Microsoft's Hohm

For a lot of people, the electricity bill is an unwanted piece of paper printed with angular graphs and big dollar signs, but with the rising cost of power in today's energy-conscious society it's becoming more important to understand exactly what all those lines and numbers mean. Microsoft's Hohm website aims to make sense of the jargon by providing personalized data on consumers' home energy consumption, and offering recommendations on how to save energy and reduce those bills.  Read More

Sony LX900 features Face Detection and Presence Sensor technology

Are you one of those people who like to have the TV on just for a bit of background noise? Or perhaps you'll leave it on while you're surfing the net or reading a book, in the hope that whatever comes on next will be a bit more interesting. If this sounds like you, then you might stand to save a few dollars on your power bills should you decide to get one of the new Sony Bravia TVs with Face Detection and Presence Sensor technology. These new features, which will dim or turn off the screen if you look away or leave the room, are included in the new Sony LX900 3D TVs due out any day now. Whilst Hitachi also appears to be researching facial recognition technologies for televisions, it looks like Sony is going to be the first to release a product with these capabilities.  Read More
