MIT Unveils Electric Bike Prototype in Copenhagen - GoodCleanTech
MIT Unveils Electric Bike Prototype in Copenhagen - GoodCleanTech
A Massachusetts Institute of Technology lab has developed a motorized bicycle for older and less-fit people to get around the city of Copenhagen, the Boston Globe reports. Today, 37 percent of Danish commuters ride bikes to work or school. The city wants to push that number to 50 percent by 2015.
MIT's new design, the Copenhagen Wheel, isn't a motorized scooter. Instead, it's just a bicycle wheel with a tiny motor attached. The whole thing fits into any existing bike frame, and gives riders extra horsepower for climbing hills or traveling long distances, the report said. The battery pack recharges by pedal power and when braking, and is completely emissions free.
In addition, the device communicates with a smart phone when mounted on the handlebars, reporting on current smog conditions, traffic congestion, and the rider's overall exertion level and progress toward fitness goals, according to the article. It can also hook into GPS radios to notify the rider where nearby friends are, and send data to city planners to aid in designing future routes.

Palo Alto has a program where if you bring in an old set of traditional lights they will give you a new set of LED lights that use 1 watt instead of 20!

Liquid Battery Developed to Store Renewable Energy - GoodCleanTech
Liquid Battery Developed to Store Renewable Energy - GoodCleanTech: "Since winds and sunlight - two of the most popular sources of renewable energy - are unpredictable forces of nature, various energy storage technologies have been developed to store power for later use. One new approach is taken by MIT professor Donald Sadoway - he has developed the first ever pure liquid battery. To keep the battery in liquid form, it's kept under constant high temperature of around 700 degrees Celsius. It's composed of three different liquid layers; two made of liquid metal alloys and one made of salt. These metal alloys are cheap and widely-available, thereby presenting the option of a cheaper storage technology."
