An almost eternal energy generator based on graphene
A group of engineers from the American University of Arkansas not only developed, but also successfully tested a circuit that is able to capture the thermal motion (Brownian motion of atoms) of graphene and subsequently convert it into electrical current. Today I want to tell you about this unique development.
How an almost impossible scheme was created
Scientific work of scientists, which, by the way, was published in the journal Physical ReviewE, was a clear confirmation of the theory developed several years ago, according to which separately located graphene is in continuous vibration and motion. And thus it is quite suitable for collecting energy.
Of course, the very idea of using continuous oscillation to collect and generate electricity is rather controversial.
After all, it comes into conflict with the statement of the famous physicist R. Freiman that the thermal motion of atoms (Brownian motion) is simply unable to do the job.
But the team led by professor of physics P. Thibado in her new experiment found that at room temperature, the thermal motion of graphene in reality generates an alternating current in the circuit, which was previously considered simply impossible.
Approach versus theory
If we recall the physicist L. Brillouin, then in 1950 he published his famous material in which the idea itself was criticized adding one diode (one-way electric gate) to the circuit to collect energy from Brownian movement.
Based on this statement, the scientists finalized the circuit and created their own with two diodes for transforming alternating current into direct current.
In the course of the experiment, it was also found that this scheme increased the transmitted power, and did not reduce it, as previously assumed.
In addition, the rate of change in resistance, which is formed through the use of diodes, adds an additional power factor.
Maxwell's demon can sleep well
According to scientists, graphene and the circuit have a symbiotic relationship. Despite the fact that the thermal environment does work with the resistor, the graphene and the circuit are at the same temperature and heat does not flow between them.
This is important, since the presence of a temperature difference would contradict the second law of thermodynamics. But specifically in this scheme, the law is not violated and Maxwell's Demon is not affected in any way.
In addition, it was found that the slow motion of graphene induces a low-frequency current, which is very important, since electronics operate on a low-frequency current.
Development prospects and future work
The work of scientists with the scheme they created continues. At this stage, the group is trying to find out if it is possible to store a DC current in a capacitor in order to use it later.
If it is possible to solve this issue and it will be possible to create a microcircuit where several millions of such mini circuits, such a design may well be used as an alternative to a low battery power.
