Purdue student group is having Green Week at Purdue. Today was the Alternative Fuel Vehicle Expo. I had my Volt, others brought a plug-in Prius, and other Priuses, a S10 converted to electric with 26 lead acid batteries, hybrid Coca Cola truck, box truck, Lafayette city bus, Tesla S (wow), Acura, LNG pickups, a Cessna 172 by Swift Fuels (headquarters in Purdue Research Park), Purdue Solar Racing Team car, and various bicycles and mopeds converted to electric. Around forty vehicles on the Memorial Mall on campus right at the busiest spot for student and staff walking. I never got my lawn chair out, was there from 9:30 AM till 3:30 PM. Must have talked to fifty plus people. I'm glad I spent five hours cleaning and detailing the car, even under the hood it was spotless. Once they found out I was an owner and not a dealer (about half the cars were brought by local dealers), they would ask a lot more questions as I gave honest answers. This was very much fun for me, I got to talk to everyone else too, and a bit surprising how much college students did NOT know about the cars.
