With the array of new technologies available in modern society, perfecting the invention of robots should be in the near future. While robots could be greatly beneficial to the development of society, powering robots could take a toll on the electricity bill. However, scientists recently discovered that robots in the future could be powered by urine.
After a team of researchers from the University of the West of England, UK, hypothesised that urine can create electricity, they decided to go one step further and create a dynamic system that can power a robot for a long time. The device mimics the pumping action of the human heart and includes a microbial fuel cell that contains urine needed to convert waste into electricity. The fuel cells contains microorganisms which digest the urine and produce electrons and are then harvested as electrical current to power the robot.
Although the invention could be a potential success in powering robots and conserving energy, the device still requires improvement and further testing. At the moment it is still fairly inefficient, but the project is off to a great start, as the device uses less electricity and it helps provide electricity to power a robot. After the researchers perfect the invention, robots in the future will have a urine-filled pumping heart to power them in the long run!
In a world of depleting resources, using human waste to convert into electricity could solve the world’s energy problems. Other than powering robots, urine could be used to power farms and even office buildings. This form of resource would be available permanently, since nearly 7 billion people produce roughly 10 billion litres of urine everyday.
