Scientists Invent Urine-Powered Robots

Lucas123 writes "Researchers have already built robots that can use microorganisms to digest waste material, such as rotten fruit and vegetables, and generate electricity from it. This time, a group of scientists has taken that concept to a strange, new place: urine-powered robots. The scientists from the University of the West of England, Bristol and the University of Bristol constructed a system in robots that functions like the human heart, except it's designed to pump urine into the robot's 'engine room,' converting the waste into electricity and enabling the robot to function completely on its own. The researchers hope the system, which can hold 24.5 ml of urine, could be used to power future generations of robots, or what they're calling EcoBots. 'In the city environment, they could re-charge using urine from urinals in public lavatories,' said Peter Walters, a researcher with the University of the West of England. 'In rural environments, liquid waste effluent could be collected from farms.'"

  5. Molecules with sufficient energy? by PuddleBoy · · Score: 2, Insightful

    I didn't realize that compounds found in urine (a waste product, after all) contained enough convertible energy to make the net work output worthwhile. After all, you have to take into consideration the energy expended in gathering and transporting the urine to the robot. The article also mentions using waste water - waste water from what? Is the world just full of all kinds of energy sources that are being discarded, or are we finally realizing that what was once considered 'marginal' capacity for energy harvesting is worth pursuing, since much of the low-hanging fruit (e.g. easily-accessible oil deposits) has already been picked?

    (Obligatory comment: I, for one, welcome our new urine-sipping robot overlords. What's that you say? You need several samples for my employment pre-screening?)

  11. I wonder what will happen... by Dcnjoe60 · · Score: 2

    The system relies on microorganisms (bacteria) in the pump to convert the proteins (organic matter) in the urine) into a fuel source for the fuel cells. I wonder what will happen when the urine from somebody taking antibiotics enters the "system" and disrupts the bacterial balance being used? Or, for that matter, urine containing any number of disease elements?

    Of course, once can engineer the bacteria to not be impacted by such things. But then that changes the question to I wonder what will happen when this super bacteria gets out in the wild?

  13. Collecting urine in Ancient Rome by Blaskowicz · · Score: 2

    A commenter said this stuff is cyclical. Well, I learned a few weeks ago that romans did collect urine from public pots and urinals. Rather than pump it into fuel cells, they just waited till it breaks down to ammonia (our bodies are smart enough to convert ammonia to urea for safe internal storage). Then it was used to maintain clothes or for teeth whitening! ugh. I'm tempted to put ammonia in my mouth but that could be a bit dangerous.

    Also why modern urinals were named after a Roman Emperor (Paris, 19th century). He came up with a pee tax, paid when buying urine at the public toilets - a place where endless thousands would come and go each day to piss, fart, shit and socialize.
    Maybe we'll go back to something similar too - there's a lot of unused piss and shit and rotten things around, but the supply of it is actually limited.

      Reminds me of an old joke...:

      A couple of nuns who were nursing sisters had gone out to the countryside to minister to an outpatient. On the way back they were a few miles from the convent when they ran out of gas.

      They were standing beside their car on the shoulder of the road when a truck approached. Seeing ladies of the cloth in distress, the driver stopped to offer his help. The nuns explained they needed some gas. The driver of the truck said he would gladly drain some from his tank, but he didn’t have a bucket or can.

      One of the nuns dug out a clean bedpan and asked the driver if he could use it. He said, “yes,” and proceeded to drain a couple of quarts of gas into the pan. He waved goodbye to the nuns and left.

      The nuns were carefully pouring the precious fluid into their gas tank when the highway patrol came by. The trooper stopped and watched for a minute before he said: “Sisters, I don’t think it will work but I sure do admire your faith!”
