New Wind Turbine Blade Design

[singlepic id=627 w=320 h=240 float=right]ALBUQUERQUE, N.M. — A new wind turbine blade design that researchers at Sandia National Laboratories developed in partnership with Knight & Carver (K&C) of San Diego promises to be more efficient than current designs. It should significantly reduce the cost-of-energy (COE) of wind turbines at low-wind-speed sites. Named “STAR” for Sweep [...]

More Energy with Less Weight

The following is from an article published in WindStats Newsletter Vol. 19, No. 4. The complete article is available from WindStats at: http://www.windstats.com. "It comes as no surprise that much of today's wind power research focuses on increasing blade lengths. The weight of a rotor can take up as much as 77% of the total [...]

InAs Quantum Dot Transitions

March 1, 2011[singlepic id=364 w=320 h=240 float=right] The fundamental interaction governing light emission from semiconductor materials is the coupling between electronic states in the semiconductor and a local electromagnetic field. The current generation of solid-state lighting devices operates in the so-called “weak-coupling” regime, in which the rate of energy transfer between the electronic states and [...]
