Everyone’s worried about energy, right? Whether it’s the thought of a peak-oil catastrophe (while a zillion gallons fester in the Gulf), or just an ecological desire to go green, we’ve become a country that frets about our future power sources. And what about pacemakers, or artificial kidneys? We can’t very well expect those to go solar, but it turns out that a sugary diet might be able to fuel the medical devices that keep you going.

Researchers at Joseph Fourier University in Grenoble, France have successfully implanted the first glucose-based biofuel cell (GBFC) in an animal. Current devices operate on batteries, which must be surgically removed when they run out of juice. Not so with these GBFCs, which are about the size of a couple of pennies stuck back-to-back (much smaller than current batteries). The graphite-based cell is wrapped in a clear dialysis bag, and contains on each side different enzymes that digest oxygen from air and sugar from food, respectively. As the enzymes break down those molecules, they create an electrical charge.

Have you ever tried to taste electricity? You can, you know… Go find a 9v battery and stick the contacts on your tongue.* Not pleasant, right? Sony has this problem (and it’s a serious, serious problem) totally licked with an RC car that runs on juice. The tasty kind of juice. You know, from fruits and stuff.

The Tomy Ene pocket RC car has, inside of it, a “bio battery” that can generate electricity from sugar in things like juice or soda. As of two years ago, each cell could output 50 mW of power. For this little car, its speed and endurance depend entirely on what you decide to feed it, and while Sony is promoting Coke products, grape juice apparently works the best.

From what I can tell, Sony’s liquid battery technology uses enzymes to digest glucose, which may mean that they last far longer (and are rechargeable more times) than those incredibly strange Nopopo urine powered batteries, which use magnesium and carbon and only last for about 4 charges. However, when you consider which kind of fluid you’d rather donate to your batteries, Nopopo might come out ahead.

Tomy’s car, with Sony’s battery inside it, is currently in the functional (yay!) prototype stage, you can see a video of it motoring around here.

Sony has been working on the development of efficient bio-batteries since 2007, but the company hasn’t really come close to commercialization so far. The batteries, which exist as prototypes, can be recharged not by using methanol as fuel but glucose. And it makes sense, as a single bowl of rice contains the same energy as 96 AA batteries.

And using the bio-battery in real products might soon become reality, it seems. This week, Japanese toymaker Takara showcased a few radio-controlled toy cars that are powered by the Sony battery. Power is generated by using enzymes to break down glucose found in sugary drinks. Cola, juice, soda and sports drinks can be used, as long as the liquid contains around 7% glucose.

Takara says the prototype cars are able to run for around 60 minutes with “one charge” of 8cc of sugary liquid. The cars can run faster when you fill them up with sweeter liquids, which basically is the same as highly concentrated fuel.

One idea behind a “cyborg life” is that we look to machines to take on critical, physical roles. These 10 machines illustrate how we have already begun passing the torch on tasks we are getting to lazy to do ourselves.

Remember handwriting? We have all but abandoned it, but the torch is being taken up by robots like Kuka, who has been put to work writing out copies of the Martin Luther bible. [BotJunkie]
Developed by Aberystwyth University and the University of Cambridge, Adam the robot was the first machine to independently discover new knowledge.

Using artificial intelligence, Adam hypothesized that certain genes in baker’s yeast code for specific enzymes which catalyse biochemical reactions in yeast. The robot then devised experiments to test these predictions, ran the experiments using laboratory robotics, interpreted the results and repeated the cycle.

The results of the experiment were later replicated and confirmed by a team of human scientists. So, it appears that computers are not only doing our calculations, but they have begun thinking for us as well. [Scientific Blogging and Link]
Are you lactose intolerant? Do you have frequent heartburn or constipation? Perhaps one day your defective digestion system could be replaced with a more advanced version of the Cloaca machine. This thing simulates actual human digestion and, in the end, produces a turd you would be proud of. [Cloaca via Link]
Dishwashers have been around for decades, but we still have to physically put the dishes into the machine. This is completely unacceptable. Panasonic’s robot takes care of the entire cleaning process from start to finish. [Link]
Seriously, what don’t smartphones do for us these days? At the most basic level, these phones are how we communicate, how we entertain ourselves and how we gather information. Thanks to apps, smartphones are taking on even greater roles—like helping us keep our girlfriends happy without actually having to do any work. Girlfriend Keeper sends automatic texts and emails to your significant other depending on the intensity of your relationship. [Girlfriend Keeper]
If you are tired of your co-workers being promoted over you, just wait until a robot becomes your new boss. JAST or the “Teamworkbot” has the ability to observe and mimic human behavior. As you will see in this video, JAST already knows how to complete the task, so it observes the human’s actions, anticipates his next move and dresses him down when he gets it wrong. [Link]
I’m pretty sure that allowing robots to take a critical role in surgery qualifies as crossing a Rubicon with respect to our level of trust in machines. The Da VInci robot enables a surgeon sitting at a console to control movements and equiptment with greater precision—resulting in a procedure that is minimally invasive. [Wikipedia]
It’s only a matter of time before technology becomes advanced enough to allow lazy parents to turn over the duties of child-rearing to robots. In fact, it’s already happening in Japan where robots like Tmsuk babysit kids in shopping malls thanks to RFID badges. They even have robot teachers like Saya that terrify elementary schoolchildren into doing their work.
The Affective Intelligent Driving Agent (AIDA) was developed by MIT to help drivers navigate, bitch about their driving when necessary, and keep them company on long trips.

“When it merges knowledge about the city with an understanding of the driver’s priorities and needs, AIDA can make important inferences,” explains Assaf Biderman, associate director of the SENSEable City Lab. “Within a week AIDA will have figured out your home and work location. Soon afterwards the system will be able to direct you to your preferred grocery store, suggesting a route that avoids a street fair-induced traffic jam. On the way AIDA might recommend a stop to fill up your tank, upon noticing that you are getting low on gas,” says Biderman. “AIDA can also give you feedback on your driving, helping you achieve more energy efficiency and safer behavior.”

While the AIDA robot helps you navigate, there are plenty of engineers working on cars that do all of the driving for you. Chevy’s “Boss” Tahoe is one of the higher profile projects that have come out in recent years, winning the DARPA Urban Challenge in 2007 after successfully navigating a 60-mile course littered with obstacles.

Boozehounds and hobby alcoholics beware: A new technology developed by the Tokyo Medical and Dental University is able to analyze your breath odors and visualize their dispersal. But it’s not only good to detect alcohol in your breath but could also be used as an indicator for diseases in the future (sorry for the silly pic – the university doesn’t supply any).

The person to be tested has to stand in a dark room and speak into a microphone-like device whose mouthpiece is covered by a special enzyme-treated gauze. The enzymes interact with components in your breath, resulting in a chemical reaction that produces light. This light is then captured by a video camera, with the footage serving as the object for analysis.

The researchers say their system can accurately measure the amount of ethanol, methanethiol, or acetone in a person’s breath. It can be used as a breath analyzer for drinkers, but also to investigate the reasons for a person’s bad breath, to evaluate liver functions and possibly even to help in the analysis of serious diseases such as diabetes or cancer.
