Air Engine / Bicycle Test Footage

This is a bicycle running on pure air pressure.
I built it as a test vehicle to collect data for making a ZERO emission, air powered car.
The ultimate fuel efficient alternative energy vehicle could run on air!
This is just the first test....
Initial results were surprising...
Range 4.5 miles on a tank.
Top speed: 18 MPH.
Not bad for a $9 bicycle from the Salvation Army, two $10 sprinkler valves, and my old scuba gear!
I'm fixing what slowed me down and wasted air, and will post a new test in a few weeks!
Thanks.

Had a chance to check out the Green Speed race bike yet?

@ufoengines I did a search on that term, but wasn't sure which bike you meant? Thanks.

I think that if I win the lottery for the third time I'm going to offer a $50000,00 prize for the first four passenger air car to cross the U.S.A, from NY to LA, in less 72 hours on it own power.

Take that Big Oil!

@ufoengines Thanks! I could 100% do that right now. I built a greatly improved transmition (designed for a small car) and have built most of the parts for a "multistage" use of the air. I also have an "instant recharge" system. I just don't have the 20K at the moment that I need for some of the higher dollar parts to make it a reality. An air car SHOULD outrun any car on the road since you can dump all you tanks to power for the fastest 1/4 mile around. I'd build the car for any investor.

Im close to finishing my air bike:-) im usin a northern industrial air drill to power it and a 1.75 to 1 ratio plus a five gallon air tank.

Awesome! I thought about using air tools, but they use such a high volume of air!

The air bike shown went over 4 miles on a tank, and the highest speed I hit was around 28 mph.

It would be SO easy to improve! And I built a two cylinder multi expansion engine, but I just haven't had time to complete and try it... Good luck, and please let me know how it goes.

@rimwydas44 They are 3500psi dive tanks putting a 200psi propane canister on it would be dumb

[fizzguts]

@MrCristoKelm Nope to small a volume and the extension cord to the run the electric motor would limit your range

[MrCristoKelm]

Err..

Design the frame of the bike to be the air pressure container and add an electric generator/air pump to the mix... if this is a good idea thumbs up this idea.

[rimwydas44]

Need more pressure , that thing cant barely support its own weight unless you put like 5 more of those propanes

How do you get compressed air? With an air compressor that runs HOT. Heat is the bullshit detector of efficiency claims. Overall efficiency of this setup oughtta be about 6 or 8% when you do a well-to-wheels calculation.

why don't you get a car?
