Hosted by Core77 and Inhabitat in partnership with the Consumer Electronics Association, this year’s Greener Gadgets Design Competition produced an incredible crop of entries from a worldwide community of designers. After sorting through hundreds of promising entries the choices are narrowed down to 50 top picks...

This one is my personal favourite:

Blight




Description

The sun provides us with energy every day. How can we use it directly for indoor applications? Blight is an optimal indoor lighting solution that is able to replace current lamps without any need of electric supply. With Blight we have not produced a new object; we have just created the design of an everlasting product: the Venetian blind. We use all the current functions of this object and add a little technology to give it a new function - to catch solar energy and convert it into electricity.

This solar blind creates a link between indoor and outdoor, taking the daylight during the day and giving it back at night. The advantage of the Venetian blind is to have a large surface exposed to sunlight in a small, cumbersome object. With the revolving blades we can follow the course of the sun in order to catch a maximum of energy. Moreover we can adjust the position of the lamp to obtain various lighting effects. The produced energy can be used to supply a computer or other devices, by means of an inverter.

The object will combine two newly-discovered technologies: Flexible solar cells, and electroluminescent foil which requires little energy. Blight is durable and ecological because power cables are not needed and solar power is clean. This improved Venetian blind could be used in the household as well as in office applications.
