Building materials are getting closer to doubling as batteries

“Concrete already builds our world, and an MIT-invented variant known as electron-­conducting carbon concrete (ec3 , pronounced “e c cubed”) holds out the possibility of helping power it, too. Now that vision is one step closer. 

Made by combining cement, water, ultra-fine carbon black, and electrolytes, ec3 creates a conductive “nanonetwork” that could enable walls, sidewalks, and bridges to store and release electrical energy like giant batteries. To date, the technology has been limited by low voltage and scalability challenges. But the latest work by the MIT team that invented ec3 has increased the energy storage capacity by an order of magnitude. With the improved technology, about five cubic meters of concrete—the volume of a typical basement wall—could store enough energy to meet the daily needs of the average home.”

“Human-mirroring robots exchange punches in Las Vegas”

“Human-like combatants stumbled a bit as they swung and kicked at each other in the Ultimate Fighting Robot (UFB) match, curiosity mixing with cheers from spectators at the event on the edge of the Consumer Electronics Show in Las Vegas. The contenders were a departure from the usual lineup at the event, known for wheeled machines equipped with wrecking tools. UFB backers are betting humanoid robots will win fans by transforming bouts from demolition derbies to mixed martial arts matches. A human referee addressed the robotic rivals as though they were flesh-and-blood fighters.

"This is the sport of the future," said Vitaly Bulatov, who co-founded UFB with his wife, Xenia. The couple from Russia envisions fans being won over by the "human stories" of the real people piloting the robot combatants. As the robots exchanged blows, commands to kick and punch came from human pilots ringside using a combination of cameras and motion-sensing Nintendo video game controllers.” (via Tech Xplore)
