The Windspire

While wind turbines are a clean, green way to generate power, they can be a bit of an eyesore and require quite a bit of room meaning, more often than not, they need to be located in sparsely populated areas far from where the generated power is actually needed. We’ve looked at AeroVironment’s innovative urban solution as well as StatoilHydro’s HyWind. Now a look at another innovative product - Windspire. The Windspire, from Reno, Nevada based Mariah Power, combats the large footprint problem by employing a propeller-free design that makes it ideal for rural, suburban, and even some urban residential environments.  Read More

New world record solar cell (Image: Fraunhofer ISE)

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE have set a new record for solar cell efficiency. Using concentrated sunlight on a specially constructed multi-junction solar cell, the research group lead by Frank Dimroth has achieved 41.1% efficiency for the conversion of sunlight into electricity.  Read More

Powerfilm's USB charger

PowerFilm demonstrated a very cool USB+2 AA battery flexible folding charger at CES 2009. We were lucky enough to snap a few pictures of the device and get a look at some samples of their amorphous silicon solar technology for printing cells onto fabric or other materials.  Read More

Kinesis' K2

Kinesis' K2 device combines a wind turbine, solar panel and internal 3800mAh battery to create a smart charger for all your handheld gadgets The device can be left in a sunny or windy place during the day and can be charge the internal battery 20 hours via wind alone or 8 hours via solar (in direct sunlight) or presumably less than 8 hours by both simultaneously.  Read More

nPower PEG

Battery running low on you're mobile phone? Sounds like it's time for a walk. That's the reality of the nPower PEG, a personal energy generator that, like battery-less flashlights which require shaking to produce energy, puts Faraday's Principle of Electromagnetic Induction to work to create a totally renewable energy source for charging your handheld electronic devices.  Read More

Rainbow Solar Inc. announces photovoltaic-glass window

Incorporating sustainable technologies like solar directly into building design is the logical next step in clean energy development and we can expect many more announcements like this one from Rainbow Solar Inc. (RSi) as the industry matures. The company has released details of its semi-transparent, photovoltaic-glass window, a next generation of BIPV (building integrated photovoltaic) which promises to generate up to 250 watts of electricity as well as providing a 100% reduction in Ultraviolet and Infrared radiation.  Read More

FloDesign wind turbine

Massachusetts-based FloDesign has developed a wind turbine that could generate electricity at half the cost of conventional wind turbines. The company's design, which draws on technology developed for jet engines, circumvents a fundamental limit to conventional wind turbines. Typically, as wind approaches a turbine, almost half of the air is forced around the blades rather than through them and the energy in that deflected wind is lost, but by using a shroud design, the company says it is able to generate as much power as a conventional wind turbine with blades twice as big in diameter.  Read More

SOLON Corporation solar modules are being used in the new installation

Arizona is now home to the world’s largest solar array using Copper Indium Gallium diSelenide (CIGS) thin-film solar cells. The 750-kilowatt (kW) system, located at Global Solar’s manufacturing facility in Tuscon, is the first commercial-scale deployment of the company’s CIGS technology.  Read More

The Black & Decker Power Meter

Black & Decker might be looking at a name change to Green & Decker with the announcement of three new Energy Saver Series products. The line consists of a Power Monitor to keep an eye on power consumption, a thermal leak detector to hunt down any leaks or drafts in the home, and an automated light switch that automatically turns lights on or off when you enter or leave a room. All devices that can help cut energy use – and energy bills as well.  Read More

California based Premier Power Renewable Energy Inc has reached the halfway point in completing the United States largest system of bi-directional solar trackers in Richmond near San Francisco. A solar tracker is a device onto which solar panels are fitted which tracks the motion of the sun across the sky - ensuring that the maximum amount of sunlight strikes the panels throughout the day. The beautiful thing about this project is that clean energy is being produced on previously unusable contaminated land.  Read More
