Scientists have created the tiniest chariot in the world, powered by microscopic algae. Researchers at the University of Tokyo devised minuscule vehicle-like structures where algae are captured in baskets connected to what they call micromachines. The design allows the algae enough freedom to swim and propel the structure. Two distinct vehicle types were developed: the “rotator,” which spins like a wheel and the “scooter,” likened to a Podracer from Star Wars, designed to move forward but demonstrated unexpected movements in tests. The team aims to explore more intricate designs for their future vehicles. These tiny algae-powered teams could eventually play a role in micro-level environmental engineering and research. The University of Tokyo said: "You’ve likely heard of horsepower, but how about algae power? Like a sled drawn by dogs or a plough pulled by oxen, researchers have created microscopic machines powered by lively, single-celled green algae.”
