Jan. 26-27 is the last weekend our San Francisco Idea House will be open to the public. The project is one of the first LEED (Leadership in Energy and Environmental Design) certified residential remodeled homes in the nation. Lots of cool eco-modern products and materials.

Open 9am-4pm Saturday and Sunday. $20 admission; No children under age 10. Click here for location information.

What's the deal with that car in the image? It's a fuel-alternative vehicle, but not a hybrid. Huh? That's a Honda Civic GX—a natural gas vehicle fueled by the "Honda Phill station" right in the garage. Low greenhouse emissions. Decreases our dependency on foreign oil. And according to an EPA certification, it's the cleanest internal combustion vehicle on earth. Literally nothing coming out the tailpipe.

If you're in the Bay Area this weekend, tour the house in person to find out about more ground-breaking green products. Or watch for the article in our March issue.
