Cyborg Snails Generate Electrical Power From Their Blood-like Fluid

One of the snails in question.

Just a few weeks ago we wrote about scientists who’d manage to draw power from the body fluids of cockroaches. Now, another team has reported achieving a similar feat with snails: a tiny biofuel cell implanted in the creatures draws glucose and oxygen from their hemolymph (the snail equivalent of blood) to generate power. And a yet-to-be-released study, Nature News reports, will feature beetles as the carriers of these minute power cells. All of this tiny cyborg excitement can be traced back to a 2003 paper, in which scientists generated power from a grape. Importantly, all of these biological generators—except, presumably, the grape—survived and thrived after their operations.

Now, we’re not talking about enough power here to run your cell phone or electric car. The snail cyborg can only produce about 0.16 microwatts of continuous power, though it can rise to more than 7 microwatts for short bursts (your average lightbulb consumes 60 watts). But if developed further, such biological generation could eventually be enough for the purposes of the military, which is interested in tiny spies that can crawl into nooks and crannies of buildings or through rubble, for instance, and would only need to generate enough energy to send signals back to their base. It’s interesting to note that this is presumably the kind of power generation referenced in The Matrix, when Morpheus explains that humans are grown in vats so that power can be generated from their bodies. But not to worry: the scientists’ next target isn’t human. They’re now aiming for a cyborg lobster.
