According to foreign media reports, for decades, scientists have been looking for an economical and efficient method to capture, store and release solar energy. Now, Swedish researchers say they have found a solution that can apply solar energy to a range of consumer applications, such as heating houses and vehicles.

Scientists at Chalmers University of Technology in Gothenburg, Sweden, have found ways to store solar energy so that it can be released in the form of heat when needed, even if the solar energy has been captured for decades Long. This innovative approach includes an energy-trapping molecule, an energy storage system that is superior to traditional battery performance (at least in terms of heating performance), and an energy storage laminate coating that can be applied to windows and textiles.
The system has a liquid molecule composed of carbon, hydrogen and nitrogen, which is the initial part of the system. When exposed to sunlight, the molecule absorbs the energy of the sun and saves it until the catalyst triggers, and then releases heat. The researchers spent nearly 10 years and $ 2.5 million to build an energy storage device. Moth-Poulsen, a 40-year-old professor in the Department of Chemistry and Chemical Engineering, said the energy storage device is extremely stable and has a lifespan that is 5 to 10 years longer than typical lithium-ion batteries on the market.
The most advanced and potentially commercially valuable part developed by the team is a transparent coating that can be used in home windows, moving vehicles, and even clothing. The coating can collect solar energy and release heat, reduce the power required to heat the space, and can suppress carbon emissions. At present, the researchers applied the coating to an entire building on campus to demonstrate the technology. The researchers said that the ideal early use of the technology was in a relatively small space, "may be able to heat electric cars or houses."
Now, it is not known whether the system can generate electricity. Although the researchers believe that the system has the potential to generate electricity, the research team is currently focused on heating / heating. The research group is one of 15 research groups dedicated to using molecular thermal solar systems to solve climate change issues. One of the motivations for the research comes from the "Paris Agreement", which requires signatory countries to control global temperature rise within 1.5 degrees Celsius.
Professor Moth-Poulsen plans to set up a spin-off company to advance the technology, and said that he is negotiating with several venture capital investors. According to his estimation, the energy storage device can be commercialized in only 6 years, and the coating needs 3 years, and it is estimated that another 50 million US dollars will be needed to bring the coating to the market. In May this year, the solar project won the Arnbergska Award from the Royal Swedish Academy of Sciences.
Professor Moth-Poulsen did not make an accurate estimate of the cost of the technology, but said that the cost of the technology must be within people's tolerance. However, the system does not require any rare or expensive elements, so it can have cost advantages. Jeffrey Grossman, a professor of materials science and engineering at the Massachusetts Institute of Technology, is also developing energy storage molecules. He said that the research at Chalmers University of Technology is crucial and can allow us to see the commercialization of energy conversion methods.
The twist drill is a Tool used to drill round holes in the workpiece by rotating cutting with a relatively fixed axis. Because of its chip slot into a spiral shape and the shape of the twist named. Spiral grooves have 2, 3, or more grooves, but 2 grooves are the most common. The twist drill can be clamped on manual or electric hand-held drilling tools or on drilling machines, milling machines, lathes or even machining centers. The bit material is usually high speed tool steel or hard alloy. Standard twist drill: The twist drill consists of the shank, neck and working part
We have five different materials,HSS-CO8%,HSS-CO5%,HSS-M2,HSS-4341,HSS-4241.From left to right there are from high quality to low quality.
