Scientists have devised a tree that generates electricity from vibrations.
Infinity of vibrations are produced around us and we do not realize, because our body is used to them.
From the wind that blows the buildings and makes them oscillate, up to our own footsteps, the passage of the cars over the bridges, or the same seismic activity in the area, which even if it is small can be measured and noticed.
How the tree that generates electricity from vibrations works
To Ohio State University scientists, all of that is Kinetic energy that is lost and that we could take advantage of in some way, and they have presented a concept that will allow us to do just that.
To harness the energy of vibrations, researchers have been based on the design of a tree without leaves but with some branches, because they discovered that its shape is ideal to capture vibrations coming from the ground or the air at the same time.
Thus, the idea is to install artificial trees with an electromechanical interior that takes advantage of the vibrations of the environmentSo the most congested areas of a city can be more efficient, but in no case would we see a row of these fake trees anywhere.
That is because the applications they have devised for these trees are very modest; It may not be enough to power entire buildings, but s for small devices or systems that normally run on batteries or connected to the electrical network.
An example are sensors that check the stability of buildings under construction, useful in case of earthquakes; in this way, the same seismic activity that endangers the building can serve to create energy to detect its consequences.
Taking advantage of even the smallest vibration in our environment
At the moment the researchers are working with computer simulations and small-scale modelsBut only with this have they already been able to demonstrate that it is possible to make an electromechanical shaft vibrate with a high amplitude at low frequencies, even when the apparatus is only suffering from high frequency forces.
Scientists found that the system reached a point where the received high-frequency energy became a low-frequency oscillation, with the tree moving from side to side clearly, and branches and trunk vibrating synchronously.
Scale models already manage to produce 2 volts of electricity, which is not much but enough to demonstrate that the concept works in order to expand the scale of the next models to be built.
Trees, ideal models for scientists
Interestingly, researchers around the world seem somewhat obsessed with cresubstitutes for real trees, since this is not the only design that takes advantage of its appearance.
For example, last year an artificial tree concept was introduced whose leaves were capable of producing electrical energy from the wind, and previously trees with solar panels were also raised.
The difference between this project and the previous ones is that it is expected to produce much more energy if they manage to capture all the vibrations that are normally around us.
