Wind energy



Section Alternative energy sources. Wind turbines (WPPs) have now reached the level of commercial maturity and in places with favorable wind speeds can compete with traditional sources of electricity. Of the various devices that convert wind energy into mechanical work, in the vast majority of cases, bladed machines with a horizontal shaft installed in the direction of the wind are used. Devices with a vertical shaft are much less commonly used. ... >>

smoke detector



Section Security devices and signaling of objects. This smoke detector can detect smoke or high concentrations of opaque dust particles suspended in the air. The device can be used in hot shops (foundries, welding), cement plants, woodworking plants, garages and closed parking lots. The device will notify you of a high concentration of smoke, harmful dust suspensions and automatically turn on the forced ventilation system ... >>

Computer fan control unit



Section Electronics and computer. The operation algorithm of the devices that control the cooling of the elements of the computer system unit, the descriptions of which have been published over the past few years, is approximately the same. As long as the temperature is not higher than the permissible one, the supply voltage reduced to 6,5 ... 7 V is supplied to the fans. At the same time, the cooling system, although it works less efficiently, is much less noisy. The voltage is usually reduced by including a resistor or a bipolar transistor in active mode in series with the fan supply circuit. Unfortunately, in addition to its main purpose, this element limits the starting current of the fan motor. As a result, its mechanical starting torque decreases and, without overcoming static friction, the fan impeller may remain stationary when the computer is turned on. If the temperature exceeds the set one (usually 50 °C), the threshold device is activated and the fan supply voltage is increased to the nominal voltage (12 V). Until the temperature drops, the cooling system works harder. However, its maximum possible efficiency is still not achieved, since a significant part of the supply voltage drops on the switching element - a bipolar transistor ... >>

Sound-absorbing silk 17.05.2024

In a world where noise is becoming increasingly intrusive, the emergence of innovative materials that can reduce its impact is of great interest. MIT researchers have unveiled a new sound-absorbing silk fabric that promises to revolutionize quiet spaces. The Massachusetts Institute of Technology (MIT) has made significant breakthroughs in the field of sound absorption. Researchers have developed a special silk fabric that can effectively absorb sound and create cozy, quiet environments. The fabric, thinner than a human hair, contains a unique vibrating fiber that is activated when voltage is applied to it. This feature allows the fabric to be used to suppress sound waves in two different ways. The first method uses fabric vibrations to generate sound waves that cover and cancel out unwanted noise, similar to noise-canceling headphones. This p ... >>

High Energy Density Capacitor 17.05.2024

Energy plays a key role in many aspects of modern life, and the ever-increasing demand for efficient and fast-charging power sources is driving innovation. Researchers at the McKelvey School of Engineering at Washington University in St. Louis have taken a significant step forward with a high-energy-density capacitor that promises to revolutionize the world of energy. A team of scientists from the McKelvey School of Engineering at Washington University in St. Louis presented the results of their latest research on heterogeneous thin-film structures for capacitors. Researchers, working with ferroelectrics, inadvertently created a capacitor with an amazing energy density that is 19 times higher than that of conventional elements. This breakthrough opens up new prospects for the development of fast-charging batteries, which are so necessary in the modern world. Capacitors play a key role in various devices, providing stable ... >>

Causes of conflicts between brothers and sisters 16.05.2024

Family relationships are often complex and multi-layered, and conflicts between siblings are no exception. Research in this area can help us understand what factors underlie these conflicts and why they occur so frequently. Let's look at some of the findings from psychologists at Arizona State University. American psychologists from Arizona State University conducted a study aimed at identifying the causes of conflicts between brothers and sisters. They found that different forms of violence, whether physical or verbal, did not depend on the gender of the siblings. This means that both girls and boys can exhibit aggressive behavior towards their loved ones. Other studies have shown that conflict between siblings often persists into adulthood, even as contact decreases. This indicates that people often follow established patterns of behavior formed in childhood. It was also found that, despite ... >>

Amazon Airship Warehouses 01.01.2017

Amazon has filed a patent application for Airborne Fulfillment Centers (AFC).

Filled with enough of the most in-demand items, such airships will fly to locations where Amazon predicts increased demand is expected, according to the patent. In turn, drones, including temperature-controlled food delivery models, will be on the AFC and sent down for fast, accurate and safe delivery.

As an example of the application of such a system, the patent cites a sporting event. For example, if there's a major championship going on down there, the Amazon airship can be loaded with snacks and themed souvenirs. In addition, the AFC could descend closer to the audience to provide audio support or display advertisements on a huge display.

In addition to Amazon's central airships, the patent also describes smaller shuttles that can transport personnel, drones, and supplies to central AFCs. They are also equipped with drones and can in turn deliver goods directly to consumers. Of course, all elements of this extensive network must be connected to inventory management systems and regulated centrally.

The patent states that airships and drones can act as network cells, transmitting weather, wind speed, direction of travel to each other, or sending e-books to readers on the ground, for example. So far, all this is more like a concept, but who knows - maybe soon the airspace of our cities will be occupied by airships and drones scurrying everywhere. The only problem is that there may not be room for flying cars.
