So, for my day job, I work for a local natural gas utility. As part of what I do, I try to promote the growth of using natural gas as a vehicle fuel. The other day, I was able to attend a natural gas vehicle expo in Nashville, TN, held at LP Field (home of the Tennessee Titans). Naturally, I had my camera with me and when such opportunities arose, I snapped a few images that are somewhat more artistically-inclined than just general expo/vehicle/promotional shots. See below.
This one is just cool. Someone converted a Pontiac GTO to run on natural gas.
Here's it's engine. That's one of the cool things about CNG as a fuel. The engine doesn't have to be much different from gasoline. Just a few hardened seals and a different fuel injection system and that's it. Old tech. New, cleaner fuel.
The above images are the work part of the expo. Seeing the cars, talking to vendors, etc. This one is the inside of a natural gas compressor (natural gas is typically compressed to 3600psi for storage in vehicles) from http://www.greenlinefuelcorp.com/.
Now the fun part of the expo. We got to tour the stadium. This was just a quick snap. But we got to go down to the field.
There's actually some interesting symmetries and lighting contrasts and stadiums can be beautiful when empty (I'm sure the architect who designed the stadium would be happy someone recognized their work :)
Anyway, that's it. It was a useful expo and it's encouraging to see so many people interested in getting away from gasoline and switching to cleaner fuels for our automobiles.
