  • Towards a greener construction with fly ash bricks

    Fly ash bricks help reduce construction waste by utilizing the powdery by-product of burning coal.

They also utilize waste from coal-based thermal plants, which often gets disposed of by being dumped in water bodies and on roadsides. In comparison to red clay bricks, fly ash bricks are less expensive and the production process doesn’t emit smoke or use the more fertile top soil. Their use has been mandated by some regions and about 150 small fly ash enterprises have emerged.

  • Treetop sensors help Indonesia eavesdrop on forests to cut logging

    In Indonesia, there are 27 “Guardian” sensors eavesdropping on forests as a way to monitor them for cases of illegal logging. The organization Rainforest Connection uses artificial intelligence to analyze the audio from these sensors and if the system picks up the sound of a chainsaw, it sends a mobile alert to community patrols in the area. This technology can be scaled for other parts of the world and habitats. “We're basically building a nervous system for the natural world," says Topher White, founder of the nonprofit.
