Purdue University engineers have designed a low-speed, high-torque powertrain system to reduce the operation costs, maintenance costs and environmental contamination of turbines that generate wind ...

If you’ve ever observed a river rushing down a mountain or played in the waves at the beach, you’ve felt that moving water contains a lot of energy. A river can push you and your kayak downstream, ...

Engineering design makes all kinds of tradeoffs. Power trades off with torque, strength trades off with weight, and cost can trade off with quality. For designing a hydroelectric turbine, one of the ...

Japan’s Ricoh has designed a micro hydropower system for sewage plants that could potentially be used in combination with ground-mounted solar or floating PV. The system features a sustainable water ...

SeaTwirl, a Swedish company, is exploring a bold new path in offshore wind energy with its floating vertical axis wind turbines (VATs). Unlike conventional horizontal axis turbines (HATs), which are ...

Reaching the ambitious targets of the Paris Agreement calls for revolutionary propulsion concepts. With the water-enhanced turbofan, MTU is working on a gas-turbine-based propulsion concept that ...

Northern California has some of the strongest offshore winds in the U.S., with immense potential to produce clean energy. But it also has a problem. Its continental shelf drops off quickly, making ...
