Escape from Berkeley
Escape From Berkeley is a road rally taking place this October, from Berkeley CA to Las Vegas NV, which is open only to alternatively fueled vehicles. It's being put on by The Shipyard, "A collaborative build space for Art and Energy". There are eight vehicles already registered, most of which are using some variation of gasification of scrap biomass as their fuel. It is open to any vehicle meeting the alt fuel requirement that can get to Berkeley by October.
This weekend they are having an Open Shop Weekend wherein registrants can work on their vehicles, also potential registrants with potential vehicles, also various interested parties and hangers-on. If the idea of getting a car to go from Berkeley to Vegas using nothing but coffee grounds appeals to you, this is your kind of road rally!
Images are of "Kristie's Flyer", a steam-powered runabout associated with the Neverwas Haul, and "Hooker Cooker" which I know nothing about but had an interesting picture. More info is available at the Escape From Berkeley site on the Vehicles page.
