Learn why NASA's mechanical battery system outperforms lithium-ion in durability and precision for energy storage. NASA's ...

like just spinning things really fast and capturing that kinetic energy, old school. I thought I’d explain an example of a mechanical battery: the flywheel. And are they making a comeback?

For millennia, humans have harnessed the power of wind. Wind fueled the boats of the Egyptians, the irrigation of the Babylonians, and the grain-grinding windmills of the Persians. Today, modern ...

That means we can transmit energy great distances in its electrical form and, when it arrives at its destination, change it into its mechanical form to do work. View the illustrated instructions ...
