Highlights of the EE&T conference

If you missed EE&T's one-day technical conference last week, check the site next week for presenter slides. Attendees with whom I spoke thought the program was awesome and were particularly impressed with keynoters Chris Scruton from the Calif. Energy Commission and Linear Technology Corp. cofounder Bob Dobkin.

Wind turbines go bladeless

A Tesla turbine has a stack of parallel disks connected to a central shaft with airfoil-shaped spacers arranged around the edge. Air enters the turbine at the edge of the disks and flows over the airfoil shaped peripheral spacers, turning the shaft. A company in New Hampshire has used this idea to devise a high-efficiency, low-maintenance wind turbine. READ MORE Read More
Permanent and Electro-Permanent magnetic systems cut energy costs on steel handling/clamping applications
Electromagnets require sophisticated high-capacity power supplies, which make them expensive to run and costly to maintain. Walker Magnetics’ development of permanent and electro-permanent magnetic systems require minimal to no outside energy source, which greatly reduces operator costs. For more detailed information on our steel handling/clamping products check us out at www.walkermagnet.com or call us at (508)853-3232 to speak to one of our engineers. Let us show you how we can save you money. Download a FREE catalog or receive literature.

This energy efficient clothes washer runs on elbow grease

The Wonder Washer uses a patented pressure system to force detergent and water into the fabric for a clean wash in just a few minutes as the operator turns a crank. It uses no electricity -- you just turn it by hand. The manufacturer, The Laundry Alternative Inc. in Nashua, N.H., claims it is gentle on clothes, using a tumble-wash process similar to that used by high-end washers costing hundreds or even thousands of dollars.

Cree XLamp MP-L multichip LEDs can now go into light fixtures via solderless sockets. Devised by Tyco, the socket also allows ample optical clearance for the a 120-degree beam angle. A snap-on connect feature for the LEDIL Tyra series of reflectors offers directional optics in 18, 30 and 50 degree beam angles. READ MORE Read More
