How can open ocean currents generate energy? Ocean currents contain kinetic energy that can be converted to electrical power using turbines. This is similar to offshore wind farms, or wind turbines ...

We walk here, we walk there, we walk everywhere. Maybe you’re headed to work or to lunch in a busy city. You’re expending energy, and the exercise is good for you. But what if, on top of that, we ...

Power stations and generators are often mentioned in the same breath, but they occupy very different roles in the energy ...

In a world chasing cleaner energy, a group of physicists may have uncovered a surprising new way to make power: by tapping into the Earth's own rotation. That's right, researchers at Princeton ...

Inside every living cell, tiny molecular machines are constantly in motion, shifting shapes, tugging on membranes and shuttling ions from one side to the other. That restless activity does more than ...
