High-altitude winds have large potential as a source of clean energy
A new survey of experts shows the promise of high-altitude wind energy, and the barriers to harnessing it Airborne wind energy—an emerging approach to harnessing high-altitude winds—could scale up fairly quickly if given significant government support for research and development, according to a survey of experts by Near Zero, a nonprofit energy research organization. Winds […]
ORNL roof and attic design proves efficient in summer and winter
A new kind of roof-and-attic system field-tested at the Department of Energy’s Oak Ridge National Laboratory keeps homes cool in summer and prevents heat loss in winter, a multi-seasonal efficiency uncommon in roof and attic design. The system improves efficiency using controls for radiation, convection and insulation, including a passive ventilation system that pulls air […]
Wind could meet many times world’s total power demand by 2030, researchers say
In 2030, if all energy is converted to clean energy, humans will consume about eleven-and-a-half terawatts of power every year, all sources combined. If there is to be a clean-energy economy based on renewable energy, wind power will no doubt have to help meet much of that demand. In a new study, researchers at Stanford […]
Enough wind to power global energy demand
Washington, D.C.— There is enough energy available in winds to meet all of the world’s demand. Atmospheric turbines that convert steadier and faster high-altitude winds into energy could generate even more power than ground- and ocean-based units. New research from Carnegie’s Ken Caldeira examines the limits of the amount of power that could be harvested […]
Forcing the molecular bond issue
New and improved model of molecular bonding from researchers at Berkeley Lab’s molecular foundry Material properties and interactions are largely determined by the binding and unbinding of their constituent molecules, but the standard model used to interpret data on the formation and rupturing of molecular bonds suffers from inconsistencies. A collaboration of researchers led by […]
