lecture / presentation description
As early as the Stone Age, humans have been using technology similar to flywheels for pottery, water wheels, and to power trains. A flywheel battery works by accelerating a rotor, or flywheel, and storing the rotational energy for use. Today, companies are experimenting with flywheel technology in ways as simple as toys to as complex as cars and spacecraft. Flywheel-powered cars save energy, are more efficient, and create less pollution, while presenting a safer option than typical battery-powered cars. While the batteries still produce emissions, their consequences are far less than the options currently embraced by society. As the technology improves, flywheel batteries will become an inexpensive, accessible, and long-term energy option. For a world in need of greener energy, flywheel batteries are the future.
