Q&A: A Circulatory System for Robots

Robert F. Shepherd is Associate Professor of Mechanical and Aerospace Engineering at Cornell University in Ithaca, NY. He is leading a team exploring the use of hydraulic fluids in soft robots to also serve as a source of energy.

Scientists from Caltech and Northwestern University have found a way to generate electricity by combining saltwater with one of life's more undesirable compounds: rust.

Our readers ask: How do you know that you have the right anode? How can you inspect the electrolyte or electrode material?

Whereas hydrogen fuel cells (e.g., proton exchange membrane (PEM) and other fuel cells) generate electricity from the chemical reaction between pure hydrogen and oxygen, direct carbon fuel cells...

Nearly 70 percent of the energy produced in the United States each year is wasted as heat. Much of that heat is less than 100 °C and emanates from things like computers, cars, or...

Heavy-duty trucks, such as the 18-wheelers that transport many of the world's goods from farm or factory to market, are virtually all powered by diesel engines. They account for a...

It's dark on the back road as a motorist speeds toward the intersection. Up ahead, the stop sign blends with the night and in seconds a deadly crash occurs. According to the U.S....

Wood-Based Technology Creates Electricity from Heat

Researchers have transformed a piece of wood into a flexible membrane that generates energy from the same type of electric current (ions) on which the human body runs. This energy is generated using charged channel walls and other unique properties of the wood’s natural nanostructures. With...

Increase in bioethanol production throughout the US has led to an increase in the process coproduct — distiller’s grains with solubles (DGS). DGS can be used to feed...

Fuel Cell/Fuel Cell Hybrid System

Fuel cells can deliver clean, reliable, and uninterrupted power nearly 100 percent of the time. Fuel cells offer the advantage of efficiency by converting chemical energy directly to electricity. They have no moving parts, thereby eliminating failures associated with pumps, blowers, heat exchangers, and other...

Fuel cells generate electricity directly from hydrogen and oxygen and produce only water vapor as emissions. But most fuel cells are too expensive,...

In the quest for abundant, renewable alternatives to fossil fuels, scientists have sought to harvest the sun’s energy through “water splitting,” an artificial photosynthesis...

Have you heard of "fatbergs?" Researcher Asha Srinivasan explains how her team is turning masses of fat, oil, and grease into biofuel.

New research from Idaho National Laboratory suggests that electric vehicle drivers could face longer charging times when temperatures drop. The reason: cold...
