New discoveries about use

New US scientists have found a way to recreate urine to produce energy.

>>>There are more than 3000 substances in urine

Recently, scientists from Bristol University (USA) have found a way to convert urine into electrical energy, used to control robots.

Over the past decade, the scientific team has successfully studied 4 different generations of EcoBots. The previous version of this robot was powered by the energy generated by rotting food, dead flies, sewage and mud.

Urine can be converted into useful electrical energy

Each of these types receives energy from fuel cells that contain the same types of bacteria as in human gut or wastewater treatment plants. These bacteria will "digest" waste, urine and at the same time create electrons. That means, they will produce a high-availability electric current.

According to scientists, the most important factor of this recycling system lies in urine pumping equipment . Currently, this device is being built from artificial muscles, helping to bring urine to the microbial electric power supply in robots.

When artificial muscles are heated by electric current, they compress the middle part of the pump, pushing urine through a small drainage tube to pump up the robot's fuel cell altitude. When the heating stops, the muscles return to their original shape, bringing more fluid into the syringe - similar to the pumping of blood in the human heart.

Although the new pump is capable of generating more electricity than it consumes, it is still not very effective. Therefore, the researchers hope to improve the performance of pumps to be used in the future generation of EcoBots.

Scientists said: 'In the future, we hope robots can be fueled from public toilets to operate under remote sensing mode. They will be called EcoBots for contributing to the reduction of environmental pollution caused by the amount of waste. "
