Jackie Flynn for Stanford News: A battery made with urea, commonly found in fertilizers and mammal urine, could provide a low-cost way of storing energy produced through solar power or other forms of renewable energy for consumption during off hours.
Developed by Stanford chemistry Professor Hongjie Dai and doctoral candidate Michael Angell, the battery is nonflammable and contains electrodes made from abundant aluminum and graphite. Its electrolyte’s main ingredient, urea, is already industrially produced by the ton for plant fertilizers.
“So essentially, what you have is a battery made with some of the cheapest and most abundant materials you can find on Earth. And it actually has good performance,” said Dai. “Who would have thought you could take graphite, aluminum, urea, and actually make a battery that can cycle for a pretty long time?” Cont'd...
Lacy Cooke for Inhabitat: The first Wattway solar road pilot in America has popped up in rural west Georgia. The Ray C. Anderson Foundation, named for sustainable manufacturing pioneer Ray Anderson, is testing renewable technologies along an 18-mile stretch of road, and recently installed 538 square feet of Colas‘ Wattway solar road system near the border between Georgia and Alabama.
Part of Georgia’s Interstate 85 was named for Anderson, but as over five million tons of carbon dioxideare emitted yearly on that road portion alone, Anderson’s family felt placing his name there didn’t honor his legacy, and began to look into renewable technologies to clear the air – so to speak. Thus began The Ray, an 18-mile living laboratory for clean technologies, including not only the solar roads, but also a solar-powered electric vehicle charging station, and WheelRight, a system people can drive over to test their tire pressure, which could lead to improved fuel inefficiency.
