In addition to hydrogen and methanol, ammonia is also considered a more climate-friendly substitute fuel. Recipe for greener concrete Concrete has a huge carbon footprint. Researchers at MIT in the USA have now developed a method to make its production more climate-friendly. The secret ingredient: baking powder. Navigating beneath the Arctic ice Under the ice, there is no GPS reception. But mapping the Arctic Ocean beneath the ice sheet is essential to understanding the effects of climate change. MIT has now developed a navigation method based on sound. The Tree Counter Thomas Crowther believes that data is key to combating climate change. The British ecologist found out that there are many more trees on earth than scientists previously believed. But still, 3 trillion are not enough. The potential for reforestation is enormous, says the renowned expert. At the Crowther Lab in Zurich, he is developing nature-based solutions to restore the global ecosystem. Twelve fans filter the air near Reykjavik To slow down climate change, a new type of plant in Iceland filters CO2 from the air. This is then mixed with water and injected into basalt. There it petrifies. Efficient CO2 storage method discovered in a bacterium The climate crisis makes the search for ways to store CO2 ever more urgent. Researchers have now broken down an enzyme in a bacterium that makes it possible to bind CO2 efficiently. Converting plastic waste into fuel Scientists have developed a new method to convert plastic waste into hydrogen through pyrolysis, a high-temperature chemical process. Clever cleaning of solar modules Dust accumulating on solar panels is a big problem. But washing the panels consumes large amounts of water. MIT engineers have now developed a waterless cleaning method. Online tool evaluates the ecological footprint of cars A new web tool called “Carculator” determines the ecological footprint of vehicles with different types of propulsion. According to the Paul Scherrer Institute (PSI) in Switzerland, the calculations are intended to serve as a decision-making aid when purchasing a car. Mitigating the effects of global warming with moon dust In a recent study, US scientists suggest using moon dust to combat global warming, since lunar dust shields a lot of sunlight with little mass. Other experts are critical of this method.
