Blue Origin made solar cells

Posted by in categories: chemistry, solar power, space travel, sustainability

Whether or not Blue Origin puts a lander on the Moon, it might play a key role in sustaining lunar operations. Jeff Bezos’ spaceflight company has revealed that it can produce solar cells and transmission wire using simulated Moon regolith. The firm’s Blue Alchemist technique uses molten electrolysis to separate the lunar soil’s aluminum, iron and silicon from bound oxygen to extract key materials. The process can build solar cells, cover glass and aluminum wire using only sunlight and the reactor’s silicon.

This approach would not only save explorers the trouble of importing material, but would be kinder to both the Moon and Earth. There are no carbon-based emissions, no chemicals and no need for water. The resulting solar cells can operate on the Moon for over a decade despite a “harsh” environment, Blue Origin claims.

As Ars Technica explains, Blue Origin is pitching this as a solution for NASA’s Artemis program and missions to Mars. The space agency could establish bases or other long-term installations while minimizing the environmental impact. While the concept of using regolith to build outposts isn’t new, earlier efforts have largely focused on habitats rather than the power supplying those off-world facilities.

Vertical solar panels could save farm land and transform agriculture

Posted by in categories: food, solar power, sustainability

The design facilitates efficient land use and can even save water lost to evaporation.

Sunstall, a California-based company, has launched a vertical solar panel, Sunzaun, which can be used in existing fields and arable lands without sacrificing them for clean green energy. The installation is much like conventional solar systems, just that the system uses bifacial solar modules, and the entire array stands like a boundary wall in the field.

As countries look to move away from fossil fuels, the interest in solar energy has increased in recent years. Countries in Europe facing harsh winters are also finding new ways of tapping into solar energy, such as installing solar panels at high altitudes… More.

Ultra-thin layers of rust generate electricity from flowing water

Posted by in categories: chemistry, solar power, sustainability

There are many ways to generate electricity—batteries, solar panels, wind turbines, and hydroelectric dams, to name a few examples… and now, there’s rust.

New research conducted by scientists at Caltech and Northwestern University shows that thin films of rust—iron oxide—can generate electricity when saltwater flows over them. These films represent an entirely new way of generating electricity and could be used to develop new forms of sustainable power production.

Interactions between metal compounds and saltwater often generate electricity, but this is usually the result of a chemical reaction in which one or more compounds are converted to new compounds. Reactions like these are what is at work inside batteries.

Salt-rejecting microchannels help make seawater drinkable using the power of the sun

Posted by in categories: nanotechnology, solar power

A solar distillation device can purify brine from reverse osmosis plants with over 10 percent salinity, as well as water taken directly from the Red Sea. The technology offers double the freshwater production rate of existing salt-rejection solar stills.

Inspired by the floating solar still in “The Life of Pi” movie, KAUST professor Qiaoqiang Gan has developed several nanomaterials and thermal isolation processes to enhance the evaporation of brackish water into pure steam. In 2016 he launched a startup, Sunny Clean Water, that produces low-cost inflatable stills capable of generating 10–20 liters of fresh water per day.

Scientists Have Developed a Living “Bio-Solar Cell” That Runs on Photosynthesis

Posted by in categories: biological, food, solar power, sustainability

Plants are often thought of as sources of food, oxygen, and decoration, but not as a source of electricity. However, scientists have discovered that by harnessing the natural transport of electrons within plant cells, it is possible to generate electricity as part of a green, biological solar cell. In a recent study published in ACS Applied Materials & Interfaces, researchers for the first time used a succulent plant to create a living “bio-solar cell” that runs on photosynthesis.

Photosynthesis is how plants and some microorganisms use sunlight to synthesize carbohydrates from carbon dioxide and water.

This bold new mission will try beaming solar power down from space

Posted by in categories: solar power, space, sustainability

The Space Solar Power Project (SSPP) began in 2011 when Donald Bren — philanthropist, chairman of the Irvine Company, and a lifetime member of the Caltech Board of Trustees — and Caltech’s then-president Jean-Lou Chameau came together to discuss the potential for a space-based solar power research project. By 2013, Bren and his wife (Caltech trustee Brigitte Bren) began funding the project through the Donald Bren Foundation, which will eventually exceed $100 million. As Bren said in a recent Caltech press release:

“For many years, I’ve dreamed about how space-based solar power could solve some of humanity’s most urgent challenges. Today, I’m thrilled to be supporting Caltech’s brilliant scientists as they race to make that dream a reality.”
