Puma Ditches Shoe Boxes in Eco-Initiative

written by Walter Wang

(Reuters) – Sporting goods maker Puma will launch eco-friendly packaging for its sneakers next year to reduce its carbon footprint, beating governments to the punch as it kisses old-fashion shoe boxes good-bye.

Puma said it would roll out the new packaging in the second half of next year and that by putting its shoes in cardboard frames wrapped in reusable shoe bags, it would save 8,500 tonnes of paper — the weight of more than 1,400 adult elephants.

It also said the change would mean a reduction of 60 percent in water and energy used during the production process and the amount needed for transportation due to lighter packaging

Ultra-Flexible Solar Cells You Might Wear Someday

written by Walter Wang

Imagine a lightweight, flexible solar cell that could be built into your clothing, allowing you to charge the batteries on gadgets from iPods to smart phones with a little help from the sun.

A team of researchers at the California University Institute of Technology (Caltech) has developed a new, super bendy solar cell made from silicon wire arrays grown on a silicon base.

The new cells enhance the absorption of sunlight and converts photons into electrons using less than half of the amount of expensive crystalline silicon used by conventional solar cells.

Harry Atwater, Howard Hughes Professor, professor of applied physics and materials science, and director of Caltech’s Resnick Institute focusing on sustainability research , led the team in the development of the new solar cells.  Atwater said the flexible cells are so rugged they can be rolled up as opposed to traditional solar cells that are made from thin, brittle wafers.
