Beating the summer heat

It is a lot easier to stay cool in the summer heat when your front door has E-stop glass and is as thick as that of a bank vault. That's one of tricks in a Smart Home we toured recently. We shot a video of our tour which will be up soon. Meanwhile you can see our write up here: eetweb.com/applications/SmartHome/index.html

Solid tires: Next energy efficiency measure?

The next generation of super efficient vehicle tires could be made from polyurethane. At least that is the claim of inventor Richard Steinke, CEO of Amerityre Corp. in Boulder City, Nev. He says he's devised a manufacturing process for building passenger and light truck tires made from solid elastomer. The resulting tires will far outlast conventional designs, run flat at high speeds for hundreds of miles, and have a low rolling resistance to boot. READ MORE

EV race car sets a record

It took only 1:38.858 for an electric race car called the EV-X11 to traverse one 2.3-mile lap at the Mazda Leguna Seca racetrack in Monterey, Calif. This is a new lap record at the track for electrics. The milestone took place at the 3rd annual REFUEL - Clean Power Motorsports Event recently. READ MORE

Shaft-locking devices

Ameriloc wind-turbine shaft-locking devices provide secure shaft/hub connections. The MLD (mechanical-locking devices) and HLD (hydraulic-locking devices) are custom engineered and manufactured for years of trouble-free service. The HLD offers faster installation. With larger diameters, such as 20.8 in., the HLD can be tensioned within minutes, compared to the several hours needed for a mechanical-locking device. A hydraulic pump, required for assembly, can be a stationary unit, but a hydraulic hand pump can also be used for tensioning at difficult-to-reach places, such as the wind-turbine turret. The MLD eliminates the need for keyways or splines, provides unlimited shaft positioning, and features zero backlash, reduced shaft stress, and high contact pressure for greater torque. It can fit into smaller installations and only requires standard tools to assemble. Features include torque up to 4,425,372 lb-ft, outer diameters up to 57.1 in, and shaft diameters up to 29.5 in.Ameridrives Couplings
