Energy-saving 'smart window'

Stanford University engineers have developed a "smart window" that can lighten or darken in under a minute -- faster than conventional dynamic windows. The new technology could be used to optimize lighting in buildings and vehicles, significantly reducing heating and cooling costs. The results are published in the Aug. 9, 2017, issue of Joule magazine.
