Third Planet Energy's booth at the Santa Monica Alt Car Expo caught my eye. Which is exactly what the folks there intended. In fact, Third Planet Energy's whole goal is to allow you to catch other people's eyes, through the use of chrome emblems that will upgrade your car's back end to identify just what kind of powertrain you're running in that thing. All electric? VegOil? Hybrid? CNG? Biodiesel? All these emblems and more are available, as you can see in the gallery photos.
