Hot air and the wind production tax credit

Our blog area this month gives kudos to Sen. Max Baucus, D-Mont for introducing a bit of logic into the debate about energy production tax credits for the wind industry. Sound reasoning from a legislator? Who would have guessed that was possible. It will be interesting to see what kind of reaction the Senator's comments receive at the upcoming wind energy show (June 3 - 6 in Atlanta). As always, send your energy efficiency news to us at [email protected].

High gas prices don’t mean peak oil

Prices at U.S. gas pumps are edging above $4/gallon, and consumers are desperately looking for someone or something to blame. But you can eliminate "peak oil" from the scapegoat list.

Zhaga saga

When light bulbs last 20 years or more, the fixtures housing them could go out of style before the bulbs go dar, The Zhaga standard lets designers create solid-state lighting that can adapt to improvements in technology and changes in taste. But it is a standard that is in flux. Here is an update on where the specs are and what to expect.

Super-efficient heat exchanger could be a game changer

It turns out that fluid swirled into a vortex can transfer heat more efficiently than when it is passed through the tubes of a conventional shell-and-tube heat exchanger. This insight comes from Georgios Vatistas, professor of Mechanical and Industrial Engineering at Concordia University in Montreal. Vatistas, an expert in vortex dynamics, has patented the idea with doctoral fellow Mohammed Fayed and has produced a prototype said to be four to six times more efficient than the traditional shell-and-tube heat exchangers found in chillers.

The case for switched reluctance motors

Technological advances let switched reluctance motor-drive systems be significantly more efficient than comparable induction motors. The resulting technology could have a big impact on motor-powered appliances and equipment of all sorts.

LED light strips

LF1B-N LED light strips come in six lengths, from 5.27 to 42.5 in., and are suitable for limited-space applications. The strips come in six colors — cool white, warm white, yellow, red, blue and green. The low-temperature, maintenance-free lights offer a lifespan four times that of fluorescent lights and have an IP65 rating. The light strips are suitable for applications in wet or dusty areas, including applications such as industrial machinery, control panels, semiconductor equipment, machine tools, lab and medical equipment, display-case lighting, sign illumination, or accent decor lighting.

Continuous-motion silicone cables

Highly flexible silicone cables, designed for continuous motion and harsh weather conditions, are suited for use in windmill turbines. These UV-resistant cables are an alternative to PVC and thermoplastic-rubber-jacketed cables that aren’t reliable in severe environments.
The crystal-clear silicone encapsulation is tear resistant, needs no external “armor” or conduit for protection, and will not deform or wear during a lifetime of more than 10 million cycles, even under tight bending radius and constant flexing conditions. The cables are unaffected when exposed to extreme temperatures of –65 to 260°C, ice, snow, saltwater, acid rain, vibration, sunlight, ozone, humidity, mechanical abuse, and most chemicals. An antifriction coating is available for applications that require abrasion and adhesion resistance. The silicone “self-heals” from small punctures and cable jacket damage can easily be repaired in the field
