Windshields to Reflect Sunlight, and Perhaps Produce Electricity

The California Air Resources Board will require new cars sold in California to have windows that reflect or absorb heat-producing rays from the sun. Starting in 2012, windows must prevent 45 percent of the sun's total heat-producing energy from entering the car, and the windshield must reject at least 50 percent. In 2016, this increases to 60 percent.

Measuring LED and Solid State Lighting Performance

Light emitting diodes (LEDs) and solid state lighting (SSL) products that incorporate LEDs pose many measurement challenges compared with other lighting elements, such as traditional tungsten and fluorescent. Advanced optical radiation measurement equipment and new techniques are often required to determine basic photometric and colorimetric parameters for LEDs and SSL products.

Advancing Technologies Harness the Power of Wind, Water, and the Sun

Renewable energy will be the world’s fastest-growing source of electricity generation over the next two decades, although it will still make up a relatively minor portion of the global energy supply, according to the Energy Information Administration. The majority of that increase will come from the use of wind power and water power, or hydropower.

NASA Energy Concept Could Harness the Power of Ocean Waves

NASA Jet Propulsion Laboratory (JPL) researchers who developed a new way to power robotic underwater vehicles believe a spin-off technology could help convert ocean energy into electrical energy on a much larger scale. The researchers hope that clean, renewable energy produced from the motion of the ocean and rivers could potentially meet an important part of the world’s demand for electricity.
