That’s right. Ocean Power Technology has designed this PowerBuoy, already installed in Hawaii. As waves roll into shore, the buoy moves up and down, generating power transmitted through an underwater cable. Inventors promise a nonpolluting, quiet, steel machine that is scalable to large power stations. Although this innovation may not produce energy as quickly as other sources, its cost will be far less, making it a conceivable alternative to expensive, unsustainable practices.
Add a couple of sunbathing seals on deck, and this will look no different than the other, less functional buoys on the water.

Ever wonder about the paper consumption involved in manufacturing books? It’s staggering. “About 20 million trees are cut down annually for virgin paper used for the production of books sold in the US alone,” according to ECO-LIBRIS co-founder, Raz Godelink. Until all books are manufactured using recycled material, Raz’s organization will plant a tree for every book we buy.
Here’s how it works — simply donate a dollar for every book you buy, and a tree will be planted in its honor.
Launched in mid-June, ECO-LIBRIS intends to become a strong voice in a call for change toward printing books in an eco-friendly manner.
