Engineers at MIT have developed a new heating and cooling reactor train that produces clean hydrogen by harnessing 40% of the solar heat it is exposed to. The technology can be scaled up to by adding more reactors to the train.
The Doughnut Economics Action Lab collaboratively produced the Buy-in Bakery, a handy mind-map of topics encountered and actions that can be taken when getting buy-in to use Doughnut Economics. The list is useful for developing a plan to get buy-in for positive change on any project I think.
George Monbiot published an excellent essay on the realities of food production in the context of the Climate Emergency, and how the nostalgic idea of returning to the land is neither realistic of viable for society.
Google's Project Green Light uses AI and the vast amount of Google Maps traffic data to identify efficiencies in traffic schedules in cities that can deliver 30% less stopping and 10% less traffic emissions.
Engineers at MIT and in China have developed a passive water desalination solution using solar power that produces 4 to 6 litres of filtered water per hour, without salt clogging up the system using currents that mimic ocean currents.
Catherine Cleary of The Irish Times tells the fantastic story about how her and her husband decided to build a forest by buying the cheapest suitable land they could find and plant 27 acres of native trees as a form of Climate Action.
Researchers at North Carolina State University have engineered new bacteria that can break down Polyethylene terephthalate (PET) plastic while in saltwater.
Hannah Ritchie published an excellent two-part explainer on the reality of aviation emissions and how the sector can respond to the Climate Emergency. Part one looks at various demand scenarios coupled with action scenarios of varying degrees and methods of reduction. Part two investigates the current landscape of aviation biofuels and the scale at which it would need to increase to meet the different demand and reduction scenarios.
