ICYMI: Getting ethanol from more than just corn
try{document.getElementById("aol-cms-player-1").style.display="none";}catch(e){}Today on In Case You Missed It: Researchers at the Oak Ridge National Laboratory created ethanol out of carbon dioxide in a way that they believe would be easy to scale up. Most importantly, the conversion happens at room temperature so it could be done nearly anywhere in the world. We are also tickled by this stop-motion music video for a new song by Dan Sultan, and enjoy the dress designer who wants to put alcohol in clothes. As always, please share any interesting tech or science videos you find by using the #ICYMI hashtag on Twitter for @mskerryd.
Superconducting sapphire wires are as cool as they sound
Copper wire's relatively cheap, pliable and can conduct electricity, but it's hardly ideal. Powering cities requires cables meters wide and the metal loses a lot of energy as heat. Fortunately, a team from Tel Aviv University thinks it's solved the problem. Borrowing a fiber of sapphire from the Oakridge National Lab in Tennessee, it developed a superconducting wire barely thicker than a human hair that conducts 40 times the electricity of its copper brethren. Cooled with liquid nitrogen, the sapphire superconductors carry current without heating up, which is key to their efficiency. The team is now working on practical applications of the technology -- because it's so small and pliable (unlike previous superconductors) it could replace copper in domestic settings and its cold efficiency makes it perfect to transmit power long distances from green energy stations. The wire's going on a world tour as we speak and will touch down at the ATSC conference in Baltimore in October. Anyone who makes jokes about wires and Baltimore will be asked to leave, politely.
