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.

After solar power, it’s time we tried snow power.

Researchers from the Japanese city of Aomori have begun to study methods to create electricity from snow to provide a sustainable energy supply and meet any power shortages.

Future smartphones, sensors, solar panels and wind turbines will contain electronics in which graphullerene is present.

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.

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.”

The UK government is supporting projects to put solar panels in space and beam energy back to Earth.

Green jobs go beyond solar panel installation and wind turbine maintenance. They’re found in fields from design to economics and in many types of management.

A new type of solar panel has achieved nine percent efficiency in converting water into hydrogen and oxygen through a process known as artificial photosynthesis.

This is a major breakthrough as it is nearly ten times more efficient than previous solar water-splitting experiments, according to a press release by the University of Michigan published on Wednesday.
