Where is the lake, consisting of pure liquid asphalt?

On the island of Trinidad, there is Peach Lake, which consists of pure liquid asphalt.

It is the world's largest reservoir of its kind. At current levels of production, the lake is predicted to be a renewable source of asphalt for 400 years.

There are other similar lakes in Venezuela and California.

Why are all flags except Nepalese rectangular?

Before the beginning of the era of navigation, state flags had a variety of forms. The rectangular shape, with an aspect ratio of 2 to 1 or 3 to 2, was the most practical for mounting on ship masts. Gradually, this form of flags became standard, first in Europe, and then around the world. The only currently non-rectangular state flag (with the exception of the square banners of Switzerland and the Vatican) is the flag of Nepal. Perhaps this is due to the fact that this landlocked mountain kingdom did not need to change the shape of the banner to be installed on ships.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Energy from the air will recharge the smartphone 07.06.2015

New technology developed by Ohio State University researchers can extend smartphone battery life by up to 30% by extracting energy from radio waves.

When transmitting signals between mobile devices, base stations and Wi-Fi routers, a large number of waves are scattered. According to one of the authors of the development Chi-Chi Chen (Chi-Chih Chen), who specializes in the design of wireless antennas, only about 3% of radio waves reach the target. By developing a special system, engineers were able to extract energy from the remaining 97% and send it to recharge the battery of the device.

The system consists of an antenna that receives radio waves and a rectifier that converts the alternating current in the antenna into direct current needed to charge the battery. A special controller is responsible for managing the system.

The system allows you to get microwatts of energy. This is not enough to power a smartphone that consumes a thousand times more energy, but it is enough to extend the life of the gadget, Chen explained.

According to Chen, energy extraction occurs only when the smartphone is transmitting a signal. When receiving a signal, the function is disabled. The system uses the smartphone's own signal, while the quality of communication remains at a high level.

The idea of converting radio signals into electricity may seem far-fetched, but the underlying principle is as old as electricity. The fact is that radio waves are actually a high-frequency form of alternating current.

The inventors patented the technology and sold the rights to use it to the American startup Nikola Labs. In early May 2015, TechCrunch Disrupt in New York demonstrated the first product based on it - a case for the iPhone 6, which includes all the necessary system components. In June 2015, the startup plans to launch fundraising for the production of cases on the Kickstarater crowdfunding website. It is expected that the cost of such an accessory will be $100. Deliveries are scheduled to begin within a 4-month period.
