    This video introduces a do-it-yourself “tabletop” watt balance, built by researchers at the National Institute of Standards and Technology, who also built the NIST 4 watt balance. Here the researchers themselves explain the principles and design highlights of both watt balances. The tabletop watt balance can measure mass to about 1% precision and costs about $400. It is made from standard LEGO pieces and a few electronics. The NIST 4 watt balance is about a million times more precise and not surprisingly more expensive, with many custom-made parts out of special metals. Both watt balances work on the same principle: equating mechanical power to electromagnetic power. An object goes on one side and is balanced by electromagnetic force on the other side. While a fun and useful DIY project, the watt balance has an even larger scope: the nature of this experiment can determine one of the fundamental constants of physics: Planck constant h. h can be determined with a known mass (m), gravitational acceleration (g) and velocity (v) of the moving mass. By determining a value for h, this type of experiment is crucial to the redefinition of the kilogram in 2018.

        Think of how many times you charge your computer in a day. Now think of how many times an entire student body on a small college campus is charging their computer on a daily basis. The amount of electricity being used up for such a simple yet crucial part of our everyday lives. Imagine going solar on college campuses. With the sun being such a constant, strong, efficient power source, we could make universities electrical systems more sustainable.

            At the end of February 2015, a lantern donation and lighting ceremony was held in the village of Sone, in Indonesia's West Timor, as part of a related project. The “Cut Out the Darkness” project, a part of Panasonic Corporation's “100 Thousand Solar Lanterns Project”, delivers solar lanterns with lantern shades designed by people from around the world, in the hope of learning about the challenges of living in areas that have no electricity.

                  ITC Transmission, a wholly-owned subsidiary of ITC Holdings Corp., the nation’s largest independent electricity transmission company, today announced its Thumb Loop high-voltage transmission project is complete with the energization of the third and final phase of the project. ITC invested an estimated $510 million to build the 345,000 volt (345 kV) line, which serves as the backbone of a system designed to meet the identified maximum wind energy potential of Michigan’s Thumb region. It also will contribute to regional system reliability and facilitate wholesale market competition.
