With the cold winter months approaching fast, Sanyo has announced the release of a new eneloop universe waist warmer in Japan. Taking the form of an adjustable belt, the warmth to belly and waist is provided by a thin film heater unit powered by a mobile booster. The company has also given its neck warmer an update to make it easier to use and added a new twin set of eneloop kairo hand warmers.  Read More

One of the downsides of the lithium-ion battery systems used in electric vehicles is that their performance, reliability, safety and durability can be negatively affected by extreme temperatures. When the all-new Ford Focus Electric debuts later this year in the U.S. it will be powered by a lithium-ion battery – no news there. What is interesting, however, is that the battery system will use cooled and heated liquid to regulate battery temperature, which should extend battery life and maximize driving range.  Read More

Heat pumps provide heating in winter and cooling in summer. While they’re OK for moderate climates, they are not efficient in extreme cold climates. Building on work that began five years ago, researchers at Purdue University are developing a new type of heat pump that is much more efficient and could allow residents in cold climates to cut their heating bills in half.  Read More

The Lap Chill Mat from laptop accessory manufacturer Targus not only places an angled comfort barrier between you and your laptop but will also help cool your poor overworked portable computer. Its wedge shape allows for air intake through the sides rather than underneath and its decent size sees it comfortably handle anything from diminutive netbooks to 17 inch gaming monsters.  Read More

Efforts to capture energy from the human body usually focus on harnessing the kinetic energy of the body’s movement. However the human body is also generating energy in the form of heat that could also be used to run low power electronic devices. New energy-scavenging systems under development at MIT could generate electricity just from differences in temperature between the body (or other warm object) and the surrounding air.  Read More

The adage “less is more” rings true when discussing energy usage - as energy costs rise, using less saves you more money each year. And studies have shown that householders who know how much energy they use on a daily basis tend to use significantly less. A new device called the Wattbox - a smart control unit for central heating and hot water heaters that learns householders' energy habits and provide immediate feedback on consumption - could deliver home energy savings of up to 20 percent without compromising comfort say UK researchers. A great feature of the Wattbox is that it is retrofittable, meaning it’s suitable for all houses, not just new ones.  Read More

Could you confidently gallivant under huge mushroom-like structures knowing that they had been glued – not bolted – together? The architects and engineers of the “Parasols” in Seville, Spain, certainly hope so because the design features components that are stuck to each other in such a way. Understandably, they say the biggest problem was finding a glue that could withstand 60°C (140°F) and therefore wouldn’t melt in Seville’s summer heat. This is a fairly important criterion for the free-standing parasols that cover an area of 150m x 70m - one of the largest architectural timber structures ever built. Researchers from the Fraunhofer Institute for Wood Research WKI in Germany have adhered to the challenge and stuck with a formula they believe will do the job.  Read More

Nothing ruins a motorcycle trip like the smell of burning nylon and the sight of your possessions scattered across the highway. Soft-sided panniers are great when you want to pack some gear for a weekend getaway, but they’re not so great if they come into contact with your bike’s hot exhaust pipe. By applying a Zircotec ceramic coating to your bike’s exhaust system, the manufacturer says you can get rid of the heat shields and protect your panniers (and passenger!) from heat damage.  Read More

Prototype roof tiles that turn white to reflect heat when they get hot seem like a pretty cool idea, as do tiles that turn black to absorb heat when it’s cold. That’s why a team of Massachusetts Institute of Technology (MIT) graduates has won the third annual MIT MADMEC (Making and Designing Materials Engineering Contest) by demonstrating their thermally-activated, color-changing, roofing material called “Thermeleon” (as in chameleon).  Read More
