Electrostatic wind power harvests wind energy with no turbine blades, gearboxes, or other expensive hardware. But there are still challenges to be overcome before the concept is ready for prime time....More
Using principles analogous to those of hydroelectric dams, wind catchers from SheerWind could generate power much less expensively than conventional wind turbines....More
Paul Karlan first thought up his Karlan Cam Engine for surface vehicles about 50 years ago when he was trying to figure out a different way to change the reciprocating motion of pistons to rotary motion....More
To improve the speed and control of rotary actuators used in laser scanning and other optical systems, engineers at Pangolin Laser Systems, Orlando, Fla., decided to take matters into their own hands and designed a new rotary actuator....More
A variable-pitch wind-turbine blade adjusts its angle with changing windspeed for higher efficiencies over a greater range of wind speeds and helps prevent turbine blade runaways and other dangerous conditions....More
The PS3X switching power supplies are 70% smaller than conventional power supplies, measuring 50.8 × 28 × 62 mm (15-W model) all the way to 95 × 38 × 159 mm (100-W model)...More
The PM3 power-monitoring and metering module is for branch and main circuit applications. It measures current and voltage, calculates power and energy usage, and provides breaker status...More
Next to the economic recovery taking hold in most markets, two topics dominate business conversations: the environment and energy. Also, the current debate about sources of energy...More
An engine being developed at Ecomotors, Allen Park, Mich., is based on an opposed-piston opposed-cylinder (OPOC) concept updated with the latest computer modeling and thermodynamic analysis...More
