These inventions were created with the intention of producing clean energy which is a kind of energy that can’t hurt the environment. These Energy Towers are made to cool the air at the top and make it come down, to be transformed.
For this, scientists sprinkle water on top of the towers, to simulate the rain, as soon as the water starts evaporating the air get cooler that makes him heavier than warmer air. This is how the force of the winds, at the base of the tower, provides the production of electricity.
These towers may be considered self-sufficient, because they only need the wind to work and also a small source of water (even if it is not potable) nearby.
Boyan Slat, a 19-year-old Dutch boy, has created a system for collecting garbage that pollutes our oceans. It is a giant barrier that floats over the seas and collects plastic. With force of the wind and the currents of the sea, the garbage arrives at the barrier and gets stuck. Because it is a "V" shaped barrier, objects float to the center and are safely collected on a platform. This way, the animals are not at risk since they can pass under the platform without getting trapped.
Some young girls from Nigeria invented an energy-generating machine, powered by urine.
This equipment works by breaking the hydrogen found in the urea and routing it to a compartment that removes all of its moisture and conducts it to a generator that produces energy.
1 liter of urine generates 6 hours of electricity.
The PrePean Printer, created by the Korean company Sanwa Newtec, is environmentally friendly because it does not use ink on its prints, instead it uses recyclable paper made up of bottles.
When placed inside the printer, the paper can be easily erased for reuse, as the machine temperature removes the previous print.
