Let Me Guess, Robots Invented These Too: Little Batteries Powered By Human Blood
It may look like the world's smallest golden wallet, but it's actually a cyborg battery. You see, in the future robots will harvest humans to provide the blood they need to recharge their batteries. Well, happy Sunday to you too!
A small colony of yeast lives inside each battery, and this living core of the fuel cell can draw energy from glucose (sugar) in blood flowing around it. According to New Scientist:
The yeast-based fuel cell produces around 40 nanowatts of power, compared to the microwatt a typical wristwatch battery might produce, Chaio says. That might be enough power for some devices if it were coupled with a capacitor to allow energy to be stored. The yeast could also be genetically engineered to boost its power output.
Great news. No really, that's just wonderful. Currently, scientists are considering the cyborg battery for use in pacemakers and other implantable devices, while robots are considering how much blood they need to power chainsaws and laser blasters. But I'll tell you one thing -- ain't no robotic vampire drilling this neck. Eat oak, Dracu-bot! *tink* Oh shit.
Thanks to David, Jon and Jamie, who refuse to donate blood to a damn robot.
