Scientists from the University of Bristol, UK, have developed a system that can convert human urine into electricity to make the heart of a robot beat. In short, they invented a robotic heart powered by urine. This system has a microbial fuel tank that feeds the urine to produce electricity. In fact, any organic liquid waste (such as rotten fruit for example) can be used to make this heart function.
For now, the electricity produced by the urine remains limited since the most impressive device that it can power is a smartphone. However, this technology may be further refined with time. In any case, this new fuel is already envisaged to operate small sensors for controlling air quality and pollution. The reason for this is that such devices do not require a lot of electricity to operate.
Here is a great way to generate renewable energy for our robots. It is still far from widespread use (requires that suitable devices are developed), but it may soon may be possible that in the near future, you use your urine to operate robots or recharge your electronic devices. We find it very strange that urine is able to charge up a mobile phone.Would you be willing to use your urine to charge your smartphone?
