Sacramento's Solar Cookers International (SCI), a group that helps communities harness the power of the sun to cook food and pasteurize water, will be holding their annual "Shine On" event Wednesday evening. The event will educate SCI's supporters on their successes of the last year and highlight future projects, said the event's coordinator Rene Hamlin. About 250 people are expected to fill the Sierra 2 Center from 5 to 9 p.m. to listen to speeches by SCI co-founder Dr. Bob Metcalf and Capitol Public Radio food reporter and solar cook Sherry Cole. Those who attend will be able to view cooking demonstrations, eat solar-cooked food and even participate in a silent auction featuring art by
