With the drought declaration driving attention to California's water woes, people are asking whether we can use renewable energy to de-salt seawater on purpose. And we probably can, but there's an elephant in the room that few seem to be discussing.
A new study published this week suggests that a bit of genetic tinkering can help a microorganism boost its ability to turn organic matter into usable fuel, which might make it a bit easier to run our vehicles on fuel that doesn't spend down our fossil fuel inheritance.
There's a video making the rounds this week showing a new wind turbine design that its developers claim will be more efficient, less resource-intensive, and safer for wildlife than conventional turbines. But do the claims stand up?
With the help of some clever engineering, Stanford engineers have harnessed tiny microorganisms that give off small amounts of electrons as they digest organic matter in sewage and other wastewater, hooking them into a circuit that charges a battery.
Add another item to the growing buzz about graphene, which ReWire has covered quite recently: in addition to being a promising candidate for electrical power storage, the single-atom thin sheet form of carbon may offer a way to squeeze a whole lot more power out of photovoltaic cells.
There's a video making the viral rounds describing a potential energy storage device that seems way too good to be true: a high capacity "battery" made in an almost absurdly simple process which can be safely composted at the end of its useful life.
When researchers were trying to figure out how to maximize the amount of time light spent inside their organic solar photovoltaic cells, they turned to an age-old technique to refine their design: evolution by natural selection.
A researcher at UC Riverside thinks he may have a way to help build the kind of microscopic structures that can make photovoltaics and lithium ion batteries far more efficient than they are now -- and it involves stealing tricks from a snail.
A prominent California ratepayer advocacy organization has slammed an agreement between the state's investor-owned utilities and the Lawrence Livermore National Laboratory to conduct studies into new renewable grid management techniques.
