Artificial photosynthesis transforms atmospheric CO2 into fuel

Via Kurzweil AI

University of Central Florida (UCF) chemistry professor has invented a revolutionary way to remove carbon dioxide (CO2) from air by triggering artificial photosynthesis in a synthetic material — breaking down carbon dioxide while also producing fuel for energy.

UCF Assistant Professor Fernando Uribe-Romo and his students used a synthetic material called a metal–organic framework (MOF), which converts carbon dioxide into harmless organic materials — similar to how plants convert CO2 and sunlight into food.

Could A Giant Vacuum Cleaner Tackle Pollution?

FastCoExist highlights a device that sucks fine particulate matter from the air, that if deployed in sufficient numbers would clean the air in cities and other polluted areas.

The Dutch inventors claim the huge ‘vacuum cleaners’ can filter most of the fine particles emitted from vehicles / power plants and through industrial pollution – that have both health and climate impacts.

Concept: Low-cost arsenic detector for drinking water

SHENDY is an open-source and low-cost arsenic detector being developed by an international group of students. The aim is to create a smartphone connected device that can test whether groundwater is safe to drink based on its arsenic content, which is often at poisonous levels in post-conflict zones and after natural disasters.

Royal Caribbean to use LNG and fuel cells on ships to reduce emissions

Luxury cruises are increasingly popular but can come with huge environmental costs around ports and whilst at sea, due to sulfur and other harmful particulates from the heavy fuel oil burnt by most ships. Royal Caribbean is aiming to reduce such emissions from future cruise liners through a combination of liquefied natural gas and fuel cells from the early 2020’s.
