Power/Performance Bits: Aug. 2

From sun to hydrocarbon fuel Researchers at the University of Illinois at Chicago have engineered a solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy. Unlike conventional solar cells, which convert sunlight into electricity that must be stored in heavy batteries, the new device converts atmosph... » read more

Incandescent bulbs might not be dead yet Can incandescent bulbs be as efficient – or even more so – than LEDs? More than 95 percent of the energy that goes into incandescents is wasted, most of it as heat, so researchers at MIT and Purdue University struck out to see if that could be changed. A conventional heated metal filament, with all its attendant losses, served as the basis. But... » read more

Direct solar energy storage Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems. To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen, the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes wate... » read more

Smaller is not always better While Moore’s Law-esque shrinking has allowed for economies of scale in many industries, when it comes to nanomedicine, however, smaller is not always better, according to researchers at UCLA. They have determined that the diminutive size of nanowire-based biosensors -- that healthcare workers use to detect proteins that mark the onset of heart failure, cancer an... » read more
