The high-tech exhibit begins with a walk down a livegreen goyellow.com pathway. As visitors pass by, they see cornstalks parting in a wavelike fashion. The opposite wall is dotted with portholelike windows that provide an introduction to different GM environmental activities worldwide.

The pathway leads up to the exhibit's open bilevel space filled with activities including an interactive trivia game about hybrid technology, a Stalk Car racing game and a memory game where players match photos from a fuel cell marathon.

Three freestanding kiosks lead visitors through an interactive learning session about fuel cells, hybrids and E85, while the main exhibit space floor is highlighted by a giant projected circular graphic controlled by motion sensors. At one point, the circle appears to hold corn kernels and, as someone walks across it, the kernels pop into popcorn while E85 messages traverse the area.

An actual FlexFuel E85-compatible vehicle is housed on the main floor for visitors to climb in and out of, while one wall houses a Chevy Tahoe chassis that demonstrates through vibrant lighting effects how a two-mode hybrid works.

Upon exiting Fuel For Thought, visitors can check out the AUTOnomy, the world's first vehicle designed around a fuel cell propulsion system.

The exhibit is easily accessed upon exiting the thrill ride, Test Track presented by General Motors, in the park's Future World section. Visit www.livegreengoyellow.com for more E85 technology information.

A new interactive exhibit at Epcot explores hybrid, ethanol and fuel cell vehicle technology.
