O.o!!!! Woah even the news is talking about Dyson spheres now o.o

By Jacopo Prisco, CNN

(CNN) — What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces.

China has just connected what it believes to be the world’s biggest solar power plant to the grid in northwestern Xinjiang. The plant covers an area of 200,000 acres and is reported to have an output of 6.09 billion kWh annually.

The new plant is in the deserts near the region’s capital Ürümqi. The site came online this Monday (June 3) and is being run by the Chinese state-owned Power Construction Corporation, according to Reuters.

Swiss researchers have developed a solar energy method using synthetic quartz to achieve temperatures above 1,000°C for industrial processes, potentially replacing fossil fuels in the production of materials like steel and cement.

Instead of burning fossil fuels to reach the temperatures needed to smelt steel and cook cement, scientists in Switzerland want to use heat from the sun. The proof-of-concept study uses synthetic quartz to trap solar energy at temperatures over 1,000°C (1,832°F), demonstrating the method’s potential role in providing clean energy for carbon-intensive industries. A paper on the research was published on May 15 in the journal Device.

The Need for Decarbonization.

A new proof-of-concept device trapped solar radiation and used it to heat an object to a blistering 1,800 degrees Fahrenheit (1,000 degrees Celsius), raising hopes that steel furnaces could be powered by solar energy.

A research team has developed a novel “pulse-shaped” light method to enhance the electrical conductivity of PbS quantum dot solar cells. This new technique, which replaces the lengthy traditional heat treatment process, generates substantial energy at regular intervals, significantly improving efficiency and addressing defects caused by light, heat, and moisture exposure. PbS quantum dots, known for their wide absorption range and low processing costs, are now more viable for commercial use. This advancement is expected to facilitate the broader application of quantum dot technology in optoelectronic devices. Credit: SciTechDaily.com.

A research team headed by Professor Jongmin Choi from the Department of Energy Science and Engineering at Daegu Gyeongbuk Institute of Science and Technology has successfully developed a “PbS quantum dot” capable of quickly improving the electrical conductivity of solar cells. This collaborative effort involved Professor Changyong Lim of the Department of Energy Chemical Engineering at Kyungpook National University, led by President Wonhwa Hong, and Professor Jongchul Lim from the Department of Energy Engineering at Chungnam National University, under the leadership of President Jeongkyoum Kim.

The team identified a method to enhance electrical conductivity through the use of “pulse-shaped” light, which generates substantial energy in a concentrated manner at regular intervals. This method could replace the heat treatment process, which requires a significant amount of time to achieve the same result. This approach is expected to facilitate the production and commercialization of PbS quantum dot solar cells in the future.

Wyoming just approved its largest solar farm – 771 megawatts (MW) of utility-scale solar plus battery storage.

Developer Enbridge has been issued a siting permit by the Industrial Siting Council to construct and operate Cowboy Solar I & II on private land leases in Laramie County, in the state’s southeast corner. Next steps will be to obtain county, environmental, and municipal permits.

Cowboy Solar I will include 400 MW of solar power and 136 MW of battery storage, while Cowboy Solar II will have 371 MW of solar power and 133 MW of battery storage.

Semiconductors are the foundation of all modern electronics. Now, researchers at Linköping University, Sweden, have developed a new method where organic semiconductors can become more conductive with the help of air as a dopant. The study, published on May 15 in the journal Nature, is a significant step toward future cheap and sustainable organic semiconductors.

“We believe this method could significantly influence the way we dope organic semiconductors. All components are affordable, easily accessible, and potentially environmentally friendly, which is a prerequisite for future sustainable electronics,” says Simone Fabiano, associate professor at Linköping University.

Semiconductors based on conductive plastics instead of silicon have many potential applications. Among other things, organic semiconductors can be used in digital displays, solar cells, LEDs, sensors, implants, and for energy storage.

The transcript features an interview with renowned science fiction author Isaac Asimov, discussing his predictions and visions for the future of space exploration, computers, robotics, and humanity’s role in shaping that future. It touches on concepts like permanent space settlements, harnessing solar power, the increasing importance of computers and AI, the impacts of robotics on jobs, and taking an optimistic yet cautionary view of technological progress. It also covers some earlier inaccurate and exaggerated predictions about robots replacing humans, as well as actual technological developments in 1982 like artificial hearts and fusion reactors. The overall theme is Asimov’s hopeful but measured outlook on future scientific and technological advancements.
