Environmentally friendly, energy-dense sugar battery developed to power the world’s gadgets

https://www.youtube.com/watch?v=Z45mU5BfpcY A Virginia Tech research team has developed a battery that runs on sugar and has an unmatched energy density, a development that could replace conventional batteries with ones that are cheaper, refillable, and biodegradable. The findings from Y.H. Percival Zhang, an associate professor of biological systems engineering in the College of Agriculture and Life... Continue Reading →

New approach developed at MIT could generate power from sunlight efficiently and on demand

https://www.youtube.com/watch?v=P8-8FveMieM A new approach to harvesting solar energy, developed by MIT researchers, could improve efficiency by using sunlight to heat a high-temperature material whose infrared radiation would then be collected by a conventional photovoltaic cell. This technique could also make it easier to store the energy for later use, the researchers say. In this case,... Continue Reading →

The U.S. wars in Afghanistan and Iraq will cost taxpayers $4 trillion to $6 trillion, taking into account the medical care of wounded veterans and expensive repairs to a force depleted by more than a decade of fighting, according to a new study by a Harvard researcher. Washington increased military benefits in late 2001 as... Continue Reading →
