University of Birmingham microbiologists have found a bacterium that excretes electricity-generating hydrogen when fed sugar, and have made electricity from waste chocolate headed for the landfill:
The team fed Escherichia coli bacteria diluted caramel and nougat waste. The bacteria consumed the sugar and produced hydrogen, which they make with the enzyme hydrogenase, and organic acids. The researchers then used this hydrogen to power a fuel cell, which generated enough electricity to drive a small fan (Biochemical Society Transactions, vol 33, p 76).
The process could provide a use for chocolate waste that would otherwise end up in a landfill. What's more, the bacteria's job doesn't have to end once they have finished chomping on the sweet stuff. Mackaskie's team next put the bugs to work on a production line that recovers precious metal from the catalytic converters of old cars.
Coming after improvements to Firefox and continued unease at Google’s life-pervading insight, this image is outperforming the ███████ ████ Virality Control Group today (via). It got me thinking about all the promises that were made. Here’s the earliest article in Google News to contain “Big browser” in its headline, published by Time Magazine on Nov. […]
The WiFi232 is a traditional old-timey old-schooley Hayes-compatible 300-115200 baud modem, no wider than its own parallel DB25 port. Automatically responds with a customizable busy message when already in a call. The killer app seems to be using it to get internet onto ancient retro portables like the TRS-80 Model 102, but it’s been put […]
Most tech-media takes on the iPhone’s 10th anniversary are bland and self-congratulatory, but I like Tom Warren’s at The Verge. He laments how Apple’s pocket computer killed his inner nerd. As a youngster, he’d be constantly tearing down and building computers, even in the sweltering heat of summer. But now… …All of that tinkering and […]

Although fully autonomous vehicles aren’t yet allowed on public streets, they are poised to dominate the roads in the not-too-distant future. But before that happens, Apple, Google, Uber, and other companies now investing in self-driving tech are going to need talented developers that can account for the dizzying array of factors at play when a […]
