Researchers Transmit Energy With A Laser In 'Historic' Power-Beaming Demonstration

An nameless reader shares a report: It comes as no shock that the steering computer systems aboard the Apollo 11 spacecraft have been impossibly primitive in comparison with the pocket computer systems all of us carry round 50 years later. However on his web site, an Apple developer analyzed the tech specs even additional and located that even one thing so simple as a contemporary USB charger is filled with extra processing energy. Forrest Heller, a software program developer who previously labored on Occipital’s Construction 3D scanner accent for cellular units, however who now works for Apple, broke down the numbers in the case of the processing energy, reminiscence, and storage capability of Google’s 18W Pixel charger, Huawei’s 40W SuperCharge, the Anker PowerPort Atom PD 2 charger, and the Apollo 11 steering pc, additionally known as the AGC. It is not simple to straight examine these fashionable units with the 50-year-old AGC, which was customized developed by NASA for controlling and automating the steering and navigation techniques aboard the Apollo 11 spacecraft.

In a time when computer systems have been the scale of large rooms, the AGC was contained in a field just some toes in size as a result of it was one of many first computer systems to be made with built-in circuits. As an alternative of plopping in an off the shelf processor, NASA’s engineers designed and constructed the AGC with someplace round 5,600 digital gates that have been able to performing almost 40,000 easy mathematical calculations each second. Whereas we measure processor speeds in gigahertz as of late, the AGC chugged alongside at 1.024 MHz. By comparability, the Anker PowerPort Atom PD 2 USB-C charger features a Cypress CYPD4225 processor working at 48 MHz with the twice the RAM of the AGC, and virtually twice the space for storing for software program directions.
