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.
Gaya Herrington, the Sustainability and Dynamic System Analysis Lead at KPMG performed a study that analysed the 1972 Club of Rome Limits To Growth model and compared it to the current state of the world. Her study found that using the Business As Usual (BAU) scenario, the world is on track from societal collapse by around 2040, and using the Comprehensive Technology (CT) scenario, a halt to growth is predicted within the next decade or so. In her own words;
Andy Lagzdins describes how he converted an air compressor that run tools in his workshop to be powered by human power, using a bicycle to recharge a 10 gallon air tank and an 80 gallon tank.
Grist published a very informative piece that explains the 7 climate tipping points that we are heading towards, and why they are called point of no return.
Kris De Decker wrote a fascinating piece in Low Tech Magazine about how to use small scale solar power in your home. Using solar panels on his balcony with a lead acid battery, he powers his lights, music system, laptops and device charging, which he calculates will cost €1,290 over 30 years. The piece also describes the Living Energy Farm that uses direct solar power without battery backups to run an entire farm with workshops, kitchen, and several homes.
