There’s so many cool things happening in conjunction with the 50th Anniversary of the Seattle Center, but my personal favorite is the energy fair, happening each day this weekend from 10-5.  Located in a big tent in the heart of the fun forest, there’s going to be a big top tent full of the latest, greatest energy ideas for your home.  zHome will be on display there.  Make sure you check out the House of the Immediate Future - sponsored by Seattle Habitat for Humanity, showcasing deep green energy technologies – it’s being built on site and will be transported to a site in Greenbridge later in the year.
