Default Pneumatic Engine Go Kart

I had this at the top of my mind for a while. I want to do something cheap, make an efficient pneumatic engine for a go kart, then run it on an drag strip 1/8 mile.

The ways I've seen them

2 Stroke

Remove the spark plug and add a hose in place for the spark plug

4 Stroke

Take the cams out, then add a lobe to the opposite side of the factory lobe. so it so from Suck Squeeze Bang Blow, now it has Suck and Blow. Inject air into the intake manifold

Rotary

What I'm thinking is to take out the two spark plugs put an hose to connect the two together

I wanna know how you're gonna fit a big enough air tank to go more than a couple feet.

1. Install 2 stroke 125cc 6speed on a decent kart chassis.
2. Run drag strip, be bored.
3. Learn to road race.
4. **** bitches.
5. Profit.

You're making the engine less efficient, daas make cents?

I hate the drag strip but i think it would be fun to experiment and Internal combustion engines are inefficient.
a ITC engine uses 25% of gas to just move the vehicle/occupants, so a typical car weights 3200lbs/ a 180lbs driver= 17.77. 25%/17.77%= 4.44% of the gas moves just you, so you waste 95.56% of gas

But here is a place supposedly you can do 20,000 miles on $10 of air with a 15% increase in power

And according to the Department Of Energy 60%-62% of Gasoline Energy goes to heating Useless parts so yes Internal Combustion Engines are Efficient

True, but this does not mean that they are the least efficient means available of propelling a car. Consider, for a moment, the amount of heat generated while compressing a tank of air to 120PSI in your garage. Scuba compressors make that process look downright chilly.

I suppose a bit of simple math would probably yield more concrete data, but I'm fairly intoxicated just at the moment. For purposes of comparison, the air tank on my paintball marker holds 68ci of air at 4500 PSI, and that only lasts me for a few hundred rounds. I can't imagine that tank propelling a combined 300-350 lbs worth of cart and rider more than about 50 feet from a stop.

I am moderately skeptical of claims made by a company whose primary business seems to involve selling shares and franchise rights to a non-existent product for which "more information will be made available" at a date which is now in the past.

This is a really cool idea, regardless of how effective it will or will not be.

I know in India, they have some air powered cars....ones that wouldn't hold up to **** on American roads. They are also using air-powered vehicles in warehouses and industrial applications where electric isn't good and can't have exhaust gases indoors.

It's a working concept.
