So I love going to this website: http://www.funforever.net/ because they post some of the weirdest and coolest things.
One thing that caught my eye was the AirPOD vehicle.
Its a car that runs totally on compressed air. A single tank of compressed will take you 13o miles. Only downfall is it will only go 45mph. Not bad if you do a lot of local driving.
Imagine only having to fill up using the air compressor at the gas station. Hmm paying $1-$2 for air. To go 130 miles the AirPOD would cost $1. Compare to a car that gets 20mpg, it would cost a little over $21 at price $3.25/gallon of gas.
I'd totally get one if its cheap and available in the US!
