Pocahontas County in West Virginia falls within the National Radio Quiet Zone. It’s home to quiet country living, friendly people, and one of the most impressive engineering marvels in the world—the Green Bank Telescope. The GBT measures radio waves from throughout the universe, but due to the telescope's extreme sensitivity, any operating wireless device can have a negative effect on its observations. But to the people who live in the NRQZ, the restrictions and the quiet, peaceful life that comes with them are welcome.
Stanford University Professor Hongjie Dai and colleagues have developed the first high-performance aluminum battery that’s fast charging, long lasting and inexpensive. The flexible, non-flammable device produces 2 volts of electricity. The research team was able to generate 5 volts - enough to power a smartphone - using two aluminum batteries and a converter.
