Physicists Develop Multifunctional Storage Device For Light

Light can be confined to a very small space using a microscopic container surrounded by reflective walls. The light can then be stored by continuous reflections and cannot escape. Physicists in Germany have now for the first time realized a microresonator that combines all the desired properties -- long storage time, small volume, and tunability to arbitrary optical frequencies, in a single monolithic device.

VT willow harvest promises cheap biomass fuel (AP)

Middlebury College business services director Tom Corbin is seen in a stand of willow in Middlebury, Vt., Thursday, Oct. 15, 2009. With a nine-acre patch of willow shrubs, Middlebury College is conducting a biomass energy experiment that seeks to answer the question: What if wood-chip burning heat systems lead to the deforestation of Vermont? Willows, which grow faster than other trees, may be the answer. Corbin has turned into a farmer of sorts, checking periodically on tightly packed rows of willows growing in a field west of Middlebury's campus.(AP Photo/Toby Talbot)AP - Middlebury College used to heat its buildings with oil, then switched to wood chips. Now it has planted a sustainable and relatively cheap fuel source — willow shrubs _that could help cut demand on the state's forests.
