Astronauts have been able to drink their own (treated and filtered) urine
Peeing in swimming pools may be hazardous to your health. That’s the message from scientists who have found that compounds in urine mix with chlorine to form chemicals that have been linked to respiratory effects in swimmers.
Public toilets are notorious for unsavory behavior and even more unsavory smells. The PPlanter is both a public toilet and a planter, composting the pee it collects to nourish pots of bamboo. And it’s apparently odor-free.
Diagnosing cancer and heart disease generally requires extensively trained personnel and expensive instruments. But one MIT research group that wants to solve that problem has designed a single injection and paper-based detection system they’re hoping to ship them everywhere a letter can travel.
To make a concrete bench, add sand, bacteria, calcium chloride, and some really concentrated pee?
Despite being a great idea
We have seen the possibility of a urine-powered robot earlier last month, but here we are with scientists from the Bristol Robotics Laboratory in the UK who claimed to have developed a prototype robotic “heart” that will successfully be able to be powered solely by human urine alone. This is an interesting development, as this prototype heart was made using a 3D printer. Needless to say, the journey is far from finished, as a full working robot happens to be under development still, as the heart is the only working component at the moment.
In fact, this “heart” is made out of a rubber-like 3D printed material that is called TangoPlus, where it can charge up to 3.5 volts and perform 33 pumps thanks to just 2 milliliters of “fresh” human urine. If one were to extrapolate this particular idea, who knows, we could have an entire slew of ecologically-friendly robots that will be able to be powered simply by using energy from waste that has been collected from urinals, and public lavatories at that. Hopefully it has some sort of useful air filter, no? It would certainly be yucky to clean the innards of the robot, especially where the urine is gathered, don’t you think so?

Robots are great and all, but they do have a tendency to ratchet up the old electricity bills. But hey, never fear, because soon they might be powered by… pee.
A team of 20 researchers from University of Alberta proudly announced a commendable achievement on Thursday. Using no fewer than five different experimental methods, they’ve discovered over 3,000 different chemical compounds in human urine. And it only took them seven years.
If you’ve ever taken a daily multivitamin you too might have noticed your urine turning a bright yellow-ish color. Take your vitamins and eat some asparagus and you might just think you’re dying the next time you pee!
