Sustainable Housing that can be Recycled

Building a house from the ground up can be environmentally damaging. Buildings have a significant carbon footprint, with over 41% of global energy consumption attributed to buildings and structures. Buildings and materials also produce dangerous emissions that pollute our air, and the construction industry alone generates more than 170 tons of debris annually. There is […]

New Beer Made from Treated Wastewater Highlights Potential of Water Reuse

As one reader noted recently, “Long live the eThings! This is a wonderful period of exploration.” The Bo e-scooter is a very different beast than the shared e-scooters from Lime […]

Artificial Photosynthesis can produce food in absence of sunlight: Study

Experiments revealed that a diverse range of food-producing organisms, including green algae, yeast, and fungal mycelium that produces mushrooms, can be grown in the dark directly on the acetate-rich electrolyzer output. This technology is approximately four times more energy efficient than growing algae photosynthetically.     According to a study conducted by the University of […]
