Scientists at the Nanyang Technological University (NTU) in Singapore have developed a cheap wind turbine that produces electricity even in very light winds.

Scientists have created a wind harvester - an inexpensive wind generator that operates in the lightest wind

With an air flow speed of up to 2 meters per second, the installation generates a voltage of three volts and generates power up to 290 microwatts. This is enough to activate the sensor or provide power to the LED lamp.

Engineers called their invention a wind harvester. According to them, such devices can replace batteries in lighting sources and structural condition sensors that are used to monitor the deterioration of structures of bridges, skyscrapers and other structures.

The wind harvester is a rectangular box measuring 15 by 20 centimeters, due to which it is easy for it to find a place in an urban environment. The casing of the wind generator is made of high-strength polymer, and the device for capturing air flows is made of widely used materials – copper, aluminum foil and Teflon.

Under the influence of wind, the inner plate begins to vibrate, due to which an electric charge is formed on the metal film. In laboratory testing, the harvester could stably power 40 LEDs at a wind speed of 4 m/s. He was also able to power the sensor device and provide it with enough power to send information about the room temperature to a mobile phone wirelessly.

The NTU team will conduct further research to further improve its device’s energy storage functions, as well as experiment with different materials to increase its power output.

Smartphones will have a flat display with thin bezels and flat side edges, like the iPhone 14. The main camera module will also receive an updated design with large lenses. Earlier, data appeared on the network that the new products will be based on the SoC Snapdragon 8 Gen 2, one of the versions will receive 12 GB of RAM. According to Geekbench tests, the smartphone scores 1497 points in the single-core test and 5089 points in the multi-core test.

The base version will get a 6.2-inch 2K AMOLED display with a 120Hz refresh rate. He is credited with the main 50-megapixel Sony IMX8 camera sensor and 120W fast wired charging.

The Pro model will receive the same Snapdragon 8 Gen 2 platform, however, according to the tests, it scores 1504 points in the single-core test and 5342 points in the multi-core test.

The Indiegogo fundraising campaign starts on December 20th. Initially, they wanted to start it already on November 25, but then the dates were shifted. The first copies of the consoles will be sent to customers in March or April 2023.

As for the features of the novelty, the OneXPlayer 2 will receive an 8.4-inch screen with a resolution of 2560 x 1600 pixels, an AMD Ryzen 7 6800U processor or some Raptor Lake generation Intel Core i7. Also, rumors attribute to the novelty from 16 GB to 32 GB of RAM and up to 2 TB of permanent memory, but this has not yet been officially confirmed.

The main feature will be removable controllers and support for the stylus on the screen – 4096 pressure levels are promised. The price has not yet been announced, but it can be assumed that the cost will be at least $ 1,000.

And on October 30, the OnexPlayer Mini Pro console launched with a Ryzen 7 6800U and Radeon 680M starting at $1,199.

In the Japanese city of Aomori, an unusual experiment will be launched in December to generate electricity using snow. It will last until spring. As expected, it will be more profitable and environmentally friendly than using a solar battery.

In Japan, they are going to produce electricity with the help of ... snow

For the experiment, a swimming pool is used in a closed school, where snow collected on the streets will be unloaded. The pool will also install heat-conducting pipes with liquid. On the one hand, they will be covered with snow, on the other, they will be heated by the sun. Due to this, a convective movement of the fluid will occur, which will drive a small turbine, and it will provide energy. The greater the temperature difference, the more energy can be obtained.

In the future, scientists plan to heat the second part of the tubes with liquid from hot underground sources, which will increase the efficiency of the system. So far, no specific figures have been given that would indicate the power of such a system, even the estimated one.

As noted, such a system will be practically waste-free, while solar panels and wind farms need expensive disposal.
