Bringing Research and Business Together for Colorado

NCAR developed and Vaisala commercialized the dropsonde, a meteorological instrument that is deployed from an aircraft into hurricanes to improve both track and intensity forecasts

News & Events

Every day, lithium-ion (Li-ion) batteries are used safely in millions of cell phones, laptops, and electric-drive vehicles (EDVs). At the same time, Li-ion batteries have a tendency to overheat in very rare occasions, which has led to electronics product recalls and the grounding of Boeing's 787 Dreamliner airplane shortly after its maiden flight. The Energy Department's National Renewable Energy Laboratory (NREL) recently patented the Internal Short Circuit (ISC) device to enhance these battery designs by testing the effects of a latent internal short circuit and related escalating temperatures, which can lead to thermal runaway and hazards for drivers, air passengers—and astronauts. 

Space explorers' very lives depend on the reliability of Li-ion batteries used to power everything from communications systems to lights and breathing apparatus. The similarities between Li-ion batteries used in spacesuits and EDVs led NREL to join forces with NASA in finding new, more precise ways to trigger internal short circuits, predict reactions, and establish safeguards in the design of battery cells and packs. Now, the resulting first-of-its-kind ISC device is being used by NREL, NASA, and manufacturers to study battery responses to these latent flaws and determine solutions. 

On 5 November, 1965, the group now known as the President’s Council of Advisors on Science and Technology (PCAST) cautioned President Lyndon B. Johnson that continued accumulation of atmospheric carbon dioxide resulting from fossil-fuel burning would “almost certainly cause significant changes” and “could be deleterious from the point of view of human beings.” The reality of human-induced climate change has now been soundly confirmed, yet public skepticism persists, and policy responses remain elusive.

On October 29, 2015, a daylong symposium will review what scientific research has revealed about climate change over the past 50 years, and offer a forward-looking assessment of the range of scientific, technological, communication, and policy options for the future.
