Farnsworth-Hirsch Fusor

The Farnsworth-Hirsch Fusor is a device that creates nuclear fusion, the process that powers the sun. It works by using high-voltage electricity to accelerate ions (charged particles) into a central point, causing them to collide at extremely high speeds. These collisions can merge the nuclei of atoms, releasing energy. The fusor's design includes two concentric cages—an inner and outer grid—that help confine the ions in a controlled space. While it demonstrates fusion principles, it's primarily used for research and educational purposes, not for practical energy production due to inefficiency and radiation safety concerns.
