Physicists say they've built an atom laser that can work 'forever'

A brand new breakthrough has allowed physicists to create a beam of atoms that behaves equally to a laser and might theoretically keep on “without end”. This might lastly imply that the expertise is on its solution to sensible utility, though vital limitations nonetheless apply. Nonetheless, it is an enormous step ahead for what’s often … Read more

New kind of ‘photo voltaic’ cell exhibits we are able to generate electrical energy even at evening

New type of 'solar' cell shows we can generate electricity even at night

Standard photo voltaic expertise absorbs incoming daylight to extend voltage. Unusual as it could sound, some supplies are in a position to work in reverse, producing energy by radiating warmth again into the chilly evening sky. A crew of engineers in Australia have now demonstrated the speculation in motion, utilizing the sort of expertise generally … Read more
