Core77 has joined forces with Popular Science, the world's largest science magazine, to periodically challenge industrial designers to incorporate cutting-edge technology and science into design solutions that address everyday problems and spot emerging opportunities. Each challenge will have a single theme, a brief, a deadline, and a chance for winners to have their designs published in Popular Science magazine and on the PopSci.com and Core77 Websites. In addition, there is a $500 prize or technology prize of similar value (at minimum).

We all know that oil sucks, and everybody knows that the wind blows. Show us what "Wind Blows" means to you and you can win 10 large!

This is one flashlight that will never cause you to worry about batteries going dead, leaking into the casing or being affected by heat or cold. It works based on the dynamo principle that was first discovered by Michael Faraday in 1831.

Introducing the solar powered LightCap™, the water bottle with a light in the lid. The LightCap is the brightest idea you’ve ever seen.

An accidental discovery at Vanderbilt University may well be the key to making light-emitting diodes the dominant lighting technology of the century. Up until very recently, the only way to make "white" light was to add yellow phosphors to bright blue LEDs. It wasn't quite right, though, as even the best "white" LED retained a blue tint. This week, we got the news that a chemistry grad student at Vanderbilt has stumbled on a way to make broad-spectrum white LEDs using quantum dots -- and in doing so, he may well have kicked off a revolution.

Zevro specializes in the development and production of unique and innovative kitchenware products designed to make your life easier.

XsunX, Inc. is developing Power Glass™ – an innovative solar energy technology that allows glass windows to produce electricity from the power of the sun. XsunX is leveraging its portfolio of patents, and developing new technologies

The revolutionary pump design converts rotational movement to reciprocating linear movement by a driving mechanism consisting of only two working parts. This makes the pump highly effective, easy to operate and very economical.

The Windsave® product has been created to provide an environmentally-friendly, low-cost source of sustainable energy, providing an opportunity for every property in Britain to play a part in "the Green Revolution". Many people have the desire to protect the environment, but our challenge has been to turn that desire into action. By developing micro-wind generation technology, our towns, cities and rural communities now have the potential to become important contributors to the country's overall energy requirements, rather than just mere consumers.

Installing clean energy requires a general understanding of the equipment, costs, and approvals required for each clean energy technology. Here we provide a variety of guides from the Trust and our affiliates to help you decide whether and how to install solar and wind, navigate approvals and interconnection processes, and purchase green electricity.

Wind power can be an excellent complement to a solar power system. Here in Colorado, when the sun isn't shining, the wind is usually blowing. Wind power is especially helpful here in the winter to capture both the ferocious and gentle mountain winds during the times of least sunlight and highest power use. In most locations (including here) wind is not suitable as the ONLY source of power--it simply fills in the gaps left by solar power quite nicely.

Learn the essential basics of using solar power so you can understand your project. Planning your project begins with understanding the basics found in this section.
