Transporting Electricity Through Air via Ultrasonic Waves

Researchers have uncovered a way of transporting electricity through air by ultrasonic waves. The level of control of electric sparks enables them to be guided around obstacles, or to hit specific spots, even into non-conductive materials.

Using Embodied Energy to Power Modular Worms and Jellyfish

A modular worm robot built by the Organic Robotics Lab and a jellyfish that was a collaboration with the Archer Group, both in Cornell Engineering, demonstrate the benefits of “embodied energy.”

How Much Do You Know About Microwave Heating?

Almost everyone has a microwave oven, but do you really understand how they work? How much do you know about microwave heating? Test your knowledge with this quiz.

NASA’s Moon Shot Launched Commercial Fuel Cell Industry

The first practical fuel cells were developed in preparation for NASA’s Apollo missions because batteries would have weighed too much. The group that produced these fuel cells, now called HyAxiom Inc., sells commercial fuel cells to power buildings and utilities.

A Yarn-Like Seawater Battery

Researchers have developed a yarn-like battery prototype that works when immersed in seawater.

Cryogenic Flux Capacitor

NASA’s Cryogenic Flux Capacitor capitalizes on the energy storage capacity of liquefied gases. By exploiting a unique attribute of nano-porous materials, aerogel in this case, fluid commodities such as oxygen, hydrogen, methane, etc. can be stored in a molecular surface-adsorbed state.

Videos of the Month

See the videos of the month, including one on Michigan Engineering racing its 17th solar car, Astrum, across the Australian Outback; one on how NASA’s Europa Clipper — a 7,000-pound spacecraft — was packed and shipped from the agency’s Jet Propulsion Laboratory in Southern California to Kennedy Space Center in Florida; one on the MIT Media Lab’s Space Exploration Initiative; and one on leveraging precision growth to convert plants into biodegradable electronic devices.

Silicone Membrane for Wearable Devices is Comfortable and Breathable

A silicone membrane for wearable devices is more comfortable and breathable thanks to better-sized pores made with the help of citric acid crystals. The new preparation technique fabricates thin, silicone-based patches that rapidly wick water away from the skin. The technique could reduce the redness and itching caused by wearable biosensors that trap sweat beneath them. Read on to learn more.
