These robots are powered by algae balls living inside
Maybe we don’t need to build environmental robots. Maybe we just need to empower life to protect itself.
Marimo are one of nature’s most alien spectacles. They are impossible-looking spheres made of algae, smoothed and toppled by currents in lakes, piling up on the floor like green puff balls. Marimo’s spherical form is what makes them so unique. Otherwise, sipping on faint sunlight beneath the water’s surface, they burp oxygen into our atmosphere just like any other plant.
