Device warns of catastrophic failure in lithium-ion batteries, robots celebrate

"Catastrophic lithium-ion battery failure" are five words Malfunctioning Eddie never wants to hear, and may not have to, thanks to a new sensor developed by the folks at the Johns Hopkins University Applied Physics Laboratory. Despite the popularity of lithium-ion batteries in everything from consumer electronics to hybrid and electric vehicles, they have been associated with a phenomenon called "thermal runaway" -- known to cause overheating and potentially, fire. The newly developed device measures the electrical parameter of the cell, which is an indicator of whether the internal layer temperatures are getting too toasty. The best part? The warning comes before the heat can reach the surface and cause catastrophic failure, perhaps saving our electronics from a fate like the one in the video after the break.

Bears blanking Packers could win you free car

Filed under: ,

The emphasis, in this case, rests heavily on the word "could." The mere question of a bet between two folks at Sawicki Motors in Rochelle, Illinois ultimately resulted in the dealership's general manager, Ron Matula, offering anyone a free car if the Chicago Bears can shut out the Green Bay Packers on Christmas Day.

The tiny little hook: you've got to buy your Chevrolet, Cadillac or Buick before the game, and if Chicago manages to make such magic you will receive a full refund. But that's nothing compared to the large hooks: da Bears are 13-point underdogs; they'll be starting their third string quarterback, Josh McCown, who in nine years has been on seven NFL teams and one CFL team, with the stats to make it clear why; da Bears will be without playmakers Matt Forte, Marion Barber, Johnny Knox and probably Devin Hester; and that depleted lineup is playing the 14-1 Green Bay Packers.

History might be on the side of the Bears and Sawicki customers, though: according to ESPN Chicago, "The Packers are one of five teams in NFL history to open a season 13-0 and then lose in their 14th game. All four of the other teams lost their 15th game, too." That's still a long way from holding Green Bay scoreless, but in the words of Jim Carrey in Dumb & Dumber, we're saying there's a chance.

So if you've been in the market for a model that Sawicki sells, no matter what happens with the Bears at least you can't lose - as long as you buy today.
