Switchable material could enable new memory chips

Small voltage can flip thin film between two crystal states — one metallic, one semiconducting — new research indicates. The research involves a thin-film material called a strontium cobaltite, or SrCoOx.

Possible Dual Rotor Technology for Wind Turbines

Energy Inventions | Wind Power | Wind TurbinesIowa State Aerospace Engineers Anupam Sharma and Hui Hu are exploring the possibility of adding a smaller, secondary rotor to wind turbines. The engineers studied the base of existing turbines and found two major problems. First, they are big round structural pieces that don’t harvest any wind energy because they are not shaped like an […]

Evaporation-powered motor and light

Scientists designed shape-changing composites that used evaporation to power locomotion and generate electricity.

Vegetarian and ‘healthy’ diets could be more harmful to the environment, researchers say

Following the USDA recommendations to consume more fruits, vegetables, dairy and seafood is more harmful to the environment because those foods have relatively high resource uses and greenhouse gas emissions per calorie, say researchers. A new study measured the changes in energy use, blue water footprint and GHG emissions associated with US food consumption patterns.

Green Cars in 2015 (Infographic)

Electric Cars | Hybrid Cars | TransportationConsidering a green car? These days it makes a lot of sense but there are so many options; electric, hybrid, hydrogen and even solar. One day soon we’ll all be driving one, so how do we choose? And if we don’t have a green car, what can you we do to help the environment in […]

Superoxide gives lithium-air batteries a jolt

In a recent experiment, scientists were able to produce stable crystallized lithium superoxide instead of lithium peroxide during battery discharging. Unlike lithium peroxide, lithium superoxide can easily dissociate into lithium and oxygen, leading to high efficiency and good cycle life.

Google Biodome: New Headquarters to Blend with Environment

Energy Politics | Environment and Sustainability | Future TechnologyToday Google announced their exciting proposal to redevelop four sites in Mountain View, California. Designed by Bjarke Ingels at BIG and Thomas Heatherwick at Heatherwick Studio, the new headquarters will be the first time Google will design and build their offices from scratch. The concept is simple and genius: instead of building permanent structures with […]
