The Purpose Of The New Technology, With The Thermoelectric Generator Of Electricity, Is To Seek To Be A Reliable And Alternative Source Of Energy

A new self-powered thermoelectric generator can produce electricity continuously and sustainably, day and night, even in cloudy conditions. This technology promises to overcome some of the limitations of traditional energy sources, such as batteries, and become a reliable power source for small electronic devices, like external sensors, according to the site Portal Energia.

Thermoelectric generators are a technology of solid mobile devices that rely on temperature differences to generate electricity, with no moving parts. However, some of these generators have unstable temperature differences and ultimately do not generate enough electricity to be useful. To improve the efficiency of these devices, a team of researchers developed a new thermoelectric generator.

This new technology utilizes two main components, called Ultra-Broadband Solar Absorber (UBSA) and Planar Radioactive Cooling Emitter (RCE), which can be applied on a flexible substrate, useful for portable devices that generate clean energy. The UBSA captures light and heats one side of the generator, while the RCE protects the other side, thus releasing heat. This technological process creates a temperature difference that is capable of generating electricity and energy more efficiently.

During the night, or on cloudy days, the temperature difference is significantly reduced due to the absence of direct sunlight. But there is still a temperature difference capable of producing electricity, with lower efficiency than under optimal conditions. The research team’s technology conducted outdoor tests in different conditions and monitored the output voltage of the device. The results revealed that it can generate electricity continuously during the day, at night, and in cloudy conditions.

During the day, the device reached a peak voltage of 166.2 mV, enough to power a sensor or a small device. At night, with a clear sky, and in cloudy conditions, the device created with the developed technology generated 14.7 mV and 95 mV, respectively. Researchers, however, continue working to further optimize the efficiency, durability, and scalability of the thermoelectric device, with the goal of testing it long-term under various conditions.

In addition, they intend to explore its potential for mass electricity production at reasonable costs and, thus, apply it in remote or underdeveloped areas where traditional energy sources are not available. In summary, this new technology promises to be a continuous and sustainable energy solution for electronic devices, becoming a small reliable power source in various conditions.

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

Four times faster than the Concorde, capable of taking passengers from New York to London in less than an hour at Mach 5.5, and with an engine that switches from turbojet to ramjet mid-flight at Mach 3.5, the Hermeus Quarterhorse went from paper to its first flight in just 19 months.

Under nearly 2 kilometers of ice in Antarctica, scientists have discovered an ancient landscape sculpted by rivers up to 60 million years ago, the size of Wales, preserved as a time capsule that could help predict the advance of ice towards the ocean.

She started by collecting oyster shells from restaurants and today she has already accumulated more than 10 tons to restore reefs, recover coastal habitats, and demonstrate how a common waste can become a tool for ocean conservation.

Bricklayers off the scaffolding? New system uses autonomous drones to position bricks and apply adhesive in the air, creating walls with two flying robots working as a team.

For the economist José Kobori, the USA gained a trump card to “blackmail” Brazil and undermine China’s influence by classifying the PCC and Comando Vermelho as terrorists, increasing the power to pressure companies, banks, and even Pix.

BYD Atto 2 DM-i flex prepares to debut in Brazil with a plug-in hybrid engine, national assembly in Camaçari, competitive pricing, and targets Creta and T-Cross in a battle that promises to heat up the compact SUV market.

Processors can become 1,000 times faster with a new device that uses light pulses, operates in 40 picoseconds, and reduces the heat that stalls data centers.

Noise in the sky frightened residents: NASA confirms that a meteor exploded over New England with a force equivalent to 230 tons of TNT

The paycheck that seemed impossible: São José employee receives R$ 7.94 after legal strike, while deductions by the City Hall affect over a thousand employees and become a target of inquiry in the City Council.

China has ceased to be just a factory for cheap products and now challenges health giants: Chinese laboratories are advancing in medicines, while other countries recalculate their medical dependence.

Scientists from the USA have buried two seismometers in Antarctica at a depth of about 2.4 km under the ice, the deepest ever recorded, and are using the IceCube observatory structure to enhance earthquake monitoring, tsunami alerts, and nuclear test surveillance.
