Crank up the compressorless A/C

With the worst of the summer heat apparently behind us, one lingering reminder of the experience is the continuing work on more efficient air conditioning schemes. And with back-to-school time comes our September-October print issue. You can find a digital version here:

Will your next car have an A/C compressor?

Well, maybe not. At least not if Sorption in the UK has anything to do with it. Researchers there claim they've come up with an adsorption-based air conditioning scheme that could eliminate the need for compressors in air conditioners and thus drastically boost fuel mileage. Moreover, their idea is more than just a lab model. READ MORE Read More


What most people think they know about energy efficiency is probably wrong

What takes more energy, making a can out of recycled aluminum or making a bottle out of recycled glass? If you think bottle recycling is the more energy efficient choice, you have a lot of company. You are among the majority of people who have misconceptions about what practices are the most energy efficient. So say researchers who hail from the Earth Institute and Center for Research on Environmental Decisions, Columbia University, Ohio State University, and Carnegie Mellon University.

Appliances more efficient in some countries than in others

The International Energy Agency recently completed collecting data on TVs and on fridges and freezers to compare the performance of products across national boundaries and identify potential key factors that may cause these differences. The commission found relatively little difference in energy consumption among cold appliances in various countries. They did, however, find wide disparities in rates of improvement in efficiencies among countries. READ MORE Read More

Innovative LED panels in the limelight

The typical way of creating a light panel with LEDs is to just put some kind of diffusing material in front of the light source. This eliminates the point light source but has the drawback of blocking a lot of the LED light, up to 40%. A start-up manufacturer in Israel called Oree Inc. has devised an LED light panel that gets away from the blocking problems of diffusion material. The details of its technique are a bit sketchy, but basically it embeds LED chips in a super-thin plastic that functions as a light guide. READ MORE Read More

Energy-saving seal

MileMaker seals offer friction-reducing and fuel-saving benefits for OE and aftermarket heavy-duty truck and trailer wheel and axle applications. The seals operate with over 50% less torque than comparable seals, resulting in over $1,000 in diesel-fuel savings over the life of the seal.
The seal, developed using an elastomer material that withstands temperatures to 350°F, is compatible with mineral and synthetic oils and grease. An integrated lathed, ground and polished wear-sleeve running surface reduces friction, lowers torque, and promotes cooler running for the main seal lip. The seal’s special dirt-exclusion fins assist with keeping contamination away from the seal. The lubed rubber OD and ID design eases installation force, resulting in less heat generation, increased seal life, and sealing of minor hub or spindle imperfections. The design’s low internal torque, aided by an internal lubricant, results in lower internal heat generation, excellent wear resistance, and improved fuel economy.
