USB PD POWER Combined as a Direct Source of Energy

N192

     Providence University President Tang Chuan Yi (formerly a professor of Department of Computer Science at Tsing Hua University) sees potential in the new USB PD Technology which he believes can lessen “technology waste” and be more eco-friendly.
     President Tang points out that every time we change a new cell phone model, we have to throw out the old ones, including the batteries and chargers, resulting in the increase of technology waste which burden the environment over the years. He hopes that by standardizing the USB interface connectors, we could lessen the burden on the environment. However, the problem of insufficient endurance of cell-phone batteries still exists today. He chuckles and says that ever since he has taken up this position his incoming phone calls have increased dramatically and his cell-phone battery has been drained of power in just a short period. It has been very common to see other presidents searching for electricity plugs to charge their phones whenever he has a meeting with them.
     President Tang believes that the improvement of USB PD technology is a great beginning towards eco-friendly standards. Not only does it cut down on technological waste but it can also improve direct current technology as well. The usage of direct current will benefit solar power because solar energy is also a kind of direct current. If one end of the USB could be attached to a solar panel, and the other end attached to an electronic device, the USB could act as a medium and reduce power loss during current conversion.
     President Tang reminds that USB PD technology is gaining awareness quickly, and Taiwan should react to it as soon as possible so as not to fall behind the rest of the world. He recommends non-government organizations to work together with government organizations to form policies and techniques that can help bring in the “Know How” on USB PD technology, and do what they can help the environment.
