For many Americans, projectors bring to mind grammar school and watching outdated health videos. But the latest innovation from Casio proves that projectors have the potential to be a hot gadget of the decade.

This week at CES, Casio debuts its Green Slim projector equipped with mercury-free laser and LED hybrid lighting that can achieve brightness up to 3,000 lumens. This means it can be used for data projection in well-lit rooms - removing the need to draw the shades or switch off lights.

Moreover, the light lasts tens of thousands of hours longer than any traditional projector currently on the market. Because it uses the technology of energy-saving light bulbs that don't emit heat, no cool down time is needed after use.

The Green Slim is also smaller than any previous models. It's 1.7 inches thick and weighs just five pounds.

"Casio is thrilled to introduce this entirely new lineup of eco-friendly Super Slim projectors," said Toshiharu Okimuro, chairman of Casio America. "The advances we have made to provide superior brightness and energy-saving features make it the perfect tool for the road warrior, instructor, gamer and general consumer for home entertainment."

The Casio product is one of many showing at the Consumer Electronics Show that promise to bring gadgets into a new, energy-saving age. According to Solve Climate, many hope that CES will provide "energy-efficient game changers" for consumers.
