Virtually noise-free Eco Whisper Turbine unveiled

Virtually noise-free Eco Whisper Turbine unveiled: "Brisbane's Renewable Energy Solutions Australia (RESA) recently unveiled the first working installation of what is claimed to be the world's quietest wind turbine. The Eco Whisper Turbine is capable of producing 20kW of electricity despite being about half the height and having half the blade diameter of more familiar three-bladed solutions, and is able to automatically adjust the position of the blades to maximize wind capture."

Walking robot uses its own weight for propulsion

Walking robot uses its own weight for propulsion: "Creating systems that are energy autonomous is a key goal in the development of robotics, and this new walking prototype from Japan's Nagoya Institute of Technology (NIT) is a big step in the right direction. To some, calling this device a robot may be a bit of a stretch, especially since it lacks electricity, motors or computers of any kind, but its entry into the Guinness Book of Records last year shows it can certainly go the distance with its weight as the only motive force."

Intelligent absorbent removes radioactive material from water

Intelligent absorbent removes radioactive material from water: "Nuclear power plants are located close to sources of water, which is used as a coolant to handle the waste heat discharged by the plants. This means that water contaminated with radioactive material is often one of the problems to arise after a nuclear disaster."

02 Pursuit motorcycle runs on compressed air

02 Pursuit motorcycle runs on compressed air: "A vehicle that runs on air. It sounds like a fantastic idea, but energy is still needed to compress the air and the losses that go hand-in-hand with converting energy still have to be taken into account, just as in fossil fuel-based propulsion systems. Pros and cons aside, we still haven't seen air powered transport make an impact in the race to find economic, environmentally-friendly ways to get from A to B. "

First-ever manned flight of an electric multicopter takes place in Germany

First-ever manned flight of an electric multicopter takes place in Germany: "By now, most readers are probably pretty familiar with quadracopters - small hovering unmanned electric aircraft, which get their lift from a set of four propellers. Well, make the whole thing larger, boost the number of propellers (and accompanying motors) to 16, and you get what German aircraft developer e-volo calls a multicopter."
