"It's been said that America is addicted to oil, but Josh Tickell is taking steps to conquer his own oil dependence -- and he hopes that the rest of the country follows in his footsteps.
Tickell is the creator of the Veggie Van Organization and director of "Fuel," which was honored as best documentary at the 2008 Sundance Film Festival.
Tickell created the Algaeus mobile, which he brought to ABC News' Times Square studio this morning.
