It is known from the history of technology that the first electric machines were electrostatic, then they were replaced by electromagnetic ones. The root cause was the lack of appropriate insulating materials and switching devices at that time. Then the authority of the masters and pillars of science began to work. If one of the young scientists tried to hint in defense of electrostatic machines, then he was immediately pointed to a place and offered to descend from heaven to earth.

How pointless is that? Indeed, hundreds of thousands of tons of water are concentrated in the clouds, and they are held due to electrostatic interactions. The energy accumulates colossal and it is worth breaking your head over how to use it for your own needs. The impetus for the start of work was one experiment carried out in 1980, when a target hit sensor was being made. In the course of the experiment, a series of automatic shots were fired at a metal sheet with an area of 2 m2 connected to an oscilloscope from a distance of 20 m. The tracer bullets showed no effect, but the usual ones instead of the expected impulses of a few millivolts gave impulses of more than a dozen volts. Calculations showed that the potential accumulated by the bullet exceeded 1000 V.

Let us describe the principle of operation of a static wind farm without mechanical conversion of types of energy. It consists in the difference in the work function of the electrons and is shown in the figure.

Electrostatic wind farm

Surface 1 is made in such a way that the work function of electrons for it is A1, and for surface 2 - A2, for aerosols moving in the air flow between the surfaces with a speed V, the work function is equal to A3. Under the condition A1>>A3>>A2, electric charges will form on the surfaces: negative on surface 1 and positive on surface 2.

Capacitor C1 accumulates charge and reduces the potential of the surfaces. Its capacity must be sufficient to prevent inequality violations and blocking of surfaces. The inverter converts the high voltage charge into low voltage alternating current and delivers it to the load. Modern semiconductor devices allow you to make an inverter with an input voltage of several kilovolts and implement this idea. About 20 years ago, it was impossible to implement this principle due to the lack of appropriate semiconductor devices.

The efficiency of a static wind farm depends on the airflow rate and the characteristics of the working surfaces. The design of the wind farm is carried out in such a way that the speed of the air flow at the working surfaces is as high as possible. Work surfaces must be protected from moisture. The practical solution of a static wind farm should be varied. There is something for wind energy enthusiasts to work on here.

This idea also has a significant drawback. The work function of A3 does not remain constant and strongly depends on the air temperature (for this reason, there is no thunderstorm in winter). This problem needs to be addressed.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Drones against coronavirus 23.02.2020

Drones are deployed in China to fight the coronavirus. Of course, the fight in this case is not directly with the virus, just drones help to perform certain work related to the outbreak.

First, loudspeaker drones are flying over the streets, reminding residents to wear masks. And although masks are intended primarily for those who have already become infected, of course everyone wears them.

The second drone scenario is even more interesting. Drones are being used at some road checkpoints. In particular, at the exit from the expressway in Shenzhen. Drones fly over the road with a large sign with a QR code attached. It is needed so that by scanning it, drivers and passengers can register on a certain government website and leave information about their health status there. Drones in this case are used so that the police have less contact with people in cars.
