There are many environmentally friendly solar gadgets and in comparison, wind power is used much less. However, this garden light looks right at home in a garden because it is shaped like a flower and uses wind energy as its source of power.

Its petals are the wind propellers and the slightest breeze is sufficient to move them. The propellers are connected to a machine which helps harness the wind energy to trun it into electricity. The energy is stored in a battery.

If you have small children in the house, you will well know how much energy they have. It is almost impossible to keep up with small kids running around and playing. Aaron Tsui, Irina Kozlovskaya, Jasen Mehta and Sergio Silva have together designed and created Rocco, a rocking horse for children which harnesses the kinetic energy unleashed when a child rocks on it.

Can you imagine a scenario where cars passing by would be able to power highway lights along with natural winds via wind turbines? Somebody did, by thinking out of the box. The turbine light is a concept at present, but think of all the power and energy it can save if this can be turned into a practical application.

The system would feature a built-in wind turbine that uses the moving air from cars on the highways to generate clean energy, which is then used to power the lights. Clean and green, eco-friendly and free!

There are many charging devices which work on solar power, but there are few that work on both solar and wind power. The Kinesis K3 is one such portable device which you can use to charge your various small gadgets like cell phones, iPods, digital cameras and the like, even if you are without electricity.

It can use solar power or the wind to charge and then transfer the charge to your device. For instance if you are biker, you can clip this on to your bike and wind will charge it. So it will work even if there is no sunlight and it is a cloudy day.

While eco-friendly consumers often talk of and use solar powered gadgets in an effort to go green, it is difficult to envisage wind as a source of energy. This is simply because windmills have to be large and attached to a grid to generate power, thus making them an economically unviable for the domestic user.

However, fast paced developments in the field of sustainable energy may make wind power affordable and more user friendly. Graeme Attey of Fremantle, Australia designed the concept which uses a modular wind turbine that is small enough to sit on the roof of a house. This turbine is about a meter in length and half a meter in width and has blades which rotate with the wind, thus generating electricity.
