We’ve been hearing about vehicle-to-grid (V2G) for quite a while, and now a team at the University of Michigan is conducting an extensive study on the technology as part of a national sustainable energy solution. While current electric plants are good at generating power, they often fall short when it comes to storage — which can be a problem when there’s a power surge or when demand increases. V2G will let hybrid-electric owners sell the power their car generates to the electrical power grid whenever the car is not in use. The research team envisions a time when millions of hybrid vehicle owners will come together to create one large battery, allowing us all to play a small part in building our nation’s energy independence. And sure, this all sounds good in theory. But wouldn’t that mean relying on the neighbors to provide a key piece of the nation’s infrastructure? Have you met the neighbors? Doesn’t that seem a little… iffy?

Researchers at the University of Michigan look to have made a fairly significant advance in the oft-explored field of plastics, with them now showing off a sheet of plastic that’s not only transparent, but as “strong as steel.” That impressive feat was apparently made possible by “mimicking a brick-and-mortar molecular structure found in seashells” or, more specifically, by mixing layers of clay nanosheets with a water-soluble polymer solution. That combination also apparently gave rise to what the researchers call the “velcro effect,” which allows any bonds that are broken to be reformed quickly, further adding to the materials strength. What’s more, to handle the tedious task of actually building the material, the researchers employed their very own robotic arm, which meticulously pieced together each layer of polymer and clay nanosheets, with 300 of each required to make a sheet the thickness of regular plastic wrap.
