Scientists from Iceland have developed a new technology that helps speed up the process of turning CO2 into ice in 2 years instead of having to wait thousands of years. A very practical idea in the context of the world recording a record increase in CO2 emissions of 37 tons last year and becoming a…
Turning seawater into clean, drinkable water is one solution to meet the growing global demand for water. Turning seawater into clean, drinkable water is one solution to meet the growing global demand for water. However, the desalination process, which involves removing salt and other minerals from seawater, is very energy intensive. To overcome this problem,…
A French factory recycles used solar cells at a rate of up to 95% for glass. Every 2 minutes, Envie 2E company’s factory line cuts 1 used solar panel. With blades heated to 300 degrees Celsius, the line will cut and separate all the layers in each panel, including the aluminum frame, glass panels and…

A Canadian startup – Oneka – has found a method to operate a floating desalination system based solely on the movement of ocean waves. Currently there are two techniques used to desalinate seawater: thermal and membrane methods. During thermal desalination, seawater is heated until it evaporates, leaving behind salt. This process is often very energy…
Satellite data revealed that this year’s ozone hole over Antarctica is twice the size of the largest ever recorded. The European Space Agency (ESA) announced that the hole in the ozone layer above Antarctica has reached a record size. The cause is unclear but it is likely related to the eruption of the Hunga Tonga…
