First All-Electric Race Car from Audi

Power to the Audi e-tron FE04 is supplied by a 200 kg (441 lb.) lithium-ion battery with 34 kWh capacity.

Built in the Great Depression, the Hoover Dam is one of the greatest engineering marvels in modern history. It once exemplified best practices when harnessing hydroelectric power as well as formed the largest reservoir in the U.S., Lake Mead, which supplies sustenance to approximately 20 million people. The world may never see another dam as magnificent as Hoover Dam, but the Renewable Energy generation industry has found its new poster child for the future of hydroelectric power generation in in-pipe hydroelectric systems.

Evaporation: the Next Big Renewable Energy Source?

The total evaporative power available in the Unite States alone approaches 325 GW, which is over 69 percent of the national electrical energy generation rate in 2015.

EMI Filters for Industrial 277 V Single-Phase Applications Including LED Lighting

Three-phase power can be drawn by either the Delta configuration or the Wye configuration. In the Delta configuration, two of the power wires are combined to create a circuit that looks like an equilateral triangle (or Delta). A neutral is combined with any of the power wires in the “Wye” configuration.

A Jean Jacket...with a Twist

In collaboration with Google, clothing maker Levi Strauss will begin selling a jean jacket with touch controls woven into the fabric.

An Inside Look at Carbon Fiber (and How It Can Change the Planet)

How are carbon fibers made and formed into products? How does carbon fiber play a role in everyday products? How does the material impact the environment? What recent technology advancements have taken place to reduce carbon fiber cost and increase availability?

Additive Manufacturing of Advanced Nuclear Fuels

The hybrid additive manufacturing process improves nuclear fuel cycle economics and safety margins.

Solvent-Free Supercap Eliminates Fire Risk

A conductive mat of porous carbon nanofibers infused with a thick, ion-rich, gel electrolyte presents a liquid-free, non-flammable device.

Practical Localized Air Quality Modeling

A Carnegie Mellon professor developed an air quality modeling tool that requires no expertise to use.

New Approach to Ultrafast Light Pulses Discovered

2D materials called molecular aggregates are effective light emitters; however, their potential as components for new kinds of optoelectronic devices has been limited by their relatively slow response time. Researchers at MIT, the University of California, Berkely and Northeastern University have found a way to overcome this problem.
