Solar powered LED light in a jar

We love finding products that make great use of solar electricity and our electronic components. How about a solar powered LED light in a mason jar? Perfect for your backyard porch or for mood lighting at a party - or even as a night light in your bathroom, bedroom or kitchen! The ones we found at MyGrillfriend.com give you a choice - it can be a soft deep orange colored light (referred to as a 'sun jar') or a beautiful shade of blue (called a 'moon jar') just by flipping a switch. The solar panel Read more [...]

How about a solar energy bikini for this summer?

We thought we'd seen just about everything powered by solar panels or solar film until we came across this bikini. Made by Solarcoterie, this bathing suit is made of photovoltaic film strips sewn together in series with conductive thread! With a USB connection you could be laying on the beach and powering your iPod at the same time. The suit is constructed of 1" x 4" solar strips which terminate in a 5V regulator and a female USB connector - perfect for powering your iPod. The down side is that Read more [...]

IKEA completes solar installation in Tempe; 8 more planned

Yesterday, IKEA announced it had flipped the switch on newly installed dual rooftop solar units at its Tempe, Arizona store. The new system is one of the largest solar systems in the Phoenix area and the third such solar energy system for the Swedish home furnishings retailer; they have similar units already in place in Brooklyn, NY and Pittsburgh, PA. The 300 kW solar energy system will generate 960,000 kWh of electricity annually from 2600 solar panels. It is the equivalent of reducing at least Read more [...]

The future of solar power: Flexible solar panels

As the popularity of solar energy grows, so does the selection of solar equipment that is made available. The big trend in solar energy right now is flexible panels. Flexible solar panels have many advantages over traditional framed solar panels. The flexible solar panels are lightweight so there is less worry in the installation process and during use. They can also be installed on a semi-permanent basis because they are very easy to remove and install elsewhere. Probably the biggest advantage Read more [...]

Are deep water floating wind turbines on the horizon?

Think of the possibilities of having deep water floating wind turbines to generate energy. Are they feasible? According the Journal of Renewable and Sustainable Energy, the answer is 'yes'. Engineers from the Marine Innovation and Technology have demonstrated that their buoyant, triangular platform which is called the WindFloat, could support a 5-megawatt wind turbine. They have conducted studies to determine whether the platform would stay erect. The platform was anchored to the ocean floor Read more [...]

Turn your old PC fans into mini wind generators

Here's a great project that you can do either to experiment with wind turbines or to generate some energy! While the amount of energy produced is not overwhelming, this project can sure get your brain moving in the right direction. The best thing about this project is that you probably already have everything you need lying around: Thick plastic bottle Old PC fan, bigger the better! A few feet of small wire A piece of wood about 1.5" square and around 20cm long Two lengths of steel Read more [...]

What is a wind turbine?

A wind turbine is a rotary device that draws energy from the wind. This is different from a windmill, which draws energy from the wind but that energy is directly converted into mechanical energy used by some sort of machinery. Wind turbines are converted into raw electricity. There are two main types, horizontal and vertical axis, of which the horizontal axis is more common. What are the differences between these two? Horizontal-axis turbines have the main rotor shaft and generator at Read more [...]
