As any surfer will tell you, waves pack a powerful punch. Now, we are one step closer to capturing the energy behind the ocean’s constant ebb and flow with an improved “blue energy” harvesting device.

What if a soft material could move on its own, guided not by electronics or motors, but by the kind of rudimentary chemical signaling that powers the simplest organisms? Researchers at the University ...

A ring of beads connected to tentacles A modeling study shows how chemical reactions can stimulate motion in simple systems, like the structure here—made of enzyme coated beads connected to ...

Now, Takahito Iida at the University of Osaka has proposed a new energy-harvesting technology that uses gyroscopic flywheel system that can be tuned to absorb energy efficiently over a broad range of ...

Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process produces per unit of fuel, physicists often compare how much of a substance’s ...

The propagation of mechanical deformations along the circular network of beads, which are shown as red, blue, green dots. Chemical waves (shown in magenta) travel in the counter-clockwise direction ...

The state-of-the-art NTP cycle is based on solid core Nuclear Engine for Rocket Vehicle Application (NERVA) class technology that is envisioned to provide a specific impulse (Isp) of 900 seconds ...

Did you know that at least since the 17 th century, humans have studied how to turn ocean waves into energy? But like with many other renewable energies, it was only after the oil price crisis of 1973 ...
