Compressed Air Engines, Engines

Cars have been designed and built to run on compressed air. Even a small cylinder of CO2 gas contains a powerful amount of potential energy.

Could such Compressed Air Engines be applies to bikes?, jet-ski's? tri-plains, hang-gliders? Lawn mowers? Golf Carts?, Children's Go-Carts and mini-bikes?, Drone-Planes?, taxi's?, buses? gas-jacuzzi's lol?

High strength lightweight plastics like a 3D tensile analogue to Kevlar with a titanium-aluminum inside lining inside to hold the nuts and bolts of the container assemblage. The steel containers currently available are much to heavy to be applied to gliders and tri-planes.

`Compressed Air Cylinders' are very versatile and everyone could have a CAC system in their backyard. It would be plugged into the regular power-mains and would compress air easily at temperature of -150 Celsius to conserve power. The CAC system would be made of steel because it has tremendous amount of pressure.

The connection taps have to be precision made with safety switches because if someone clumsily unscrews a plug, the air-pressure would be powerful enough to launch the plug with your hand with enough force to rip your arm off.

CAC systems could be used to power all mechanical appliances Power Generators, Air Conditioners, Fridges, Washing-Machines as-well as `The Great Outdoors versions of such things like: Tent, Bus-Coach-tours and Caravan equipment including drills chainsaws, fencing nail-guns, mechanical-tow line when your 4 wheel-drive becomes bogged in the outback during the monsoon mud season, car jack and unscrew bolt gun, low voltage generators to power & recharge radio-transmitters, mobile/cellphones, satellite television transmitters/receivers.

CAC system could store domestically generated power like Solar power and wind-turbine power.

I like compress air power But I am mechanical engineer major. I see a lot of potential for this tech mainly because it cost less than fuel cells and can recharge faster than batteries. Also they are improving the energy density all the time.

The exhaust from an air motor can also be used for air conditioning.

Hold on to you're seat because I think I could design car engines that would blow your sox off.

You're car will run on CAC systems primarily when cruising however the CAC engine would be designed in such a way that fuel can be injected into the energy when extra power is required and would function like a thermal combustion engine.

With such an engine there is no need for a carburetor or air intake valve, It could run underwater. The CAC would behave like a N2O (Nitrous Oxide) bottle that's been put though a supercharger and fed into a conventional internal combustion engine. The acceleration and speed would be `ends of the Earth fantastic'

CAC Thermal Combustion Engine (I coined the term) are not meant to be flame throwing jet cars.

The cars would run cleanly on compressed air in their own right. However the compressed air could have it's pressure massively increased with an extra throttle that would inject fuel into the Compressed Air Engine if need be.

The best type Compressed Air Thermal Combustion Engine would be an engine that recycles the heat from the exhaust so that even the exhaust doesn't look like a flame throwing turbo-charger. There has to be a heat sink that contains the thermal heat and recycles it into mechanical/electrical energy.

The difference between Compressed Air Engines and MY CAC Thermal Combustion Engines is that my TCE would function with whatever the temperature of Compressed Air. It would have additional technology between the `CAC(Compressed Air Cylinder)' and the Engine that converts the pressure of the potential energy into Mechanical Energy

The additional technology would chamber apparatus containing a turbine compressor. Compressed Air would simply flow through it normally like though a pipe and drive the car. However when a small amount of fuel is injected into the chamber the turbine would combust the fuel increasing the temperature of the bulk of Compressed Air entering the Compressed Air Engine

That means as an example if the CAE produces 45 kilowatts of power with cold Compressed Air then the power would increase incrementally with the raising of the temperature of the gas entering the engine. A contained chamber of strategically geared centrifuge compressors would only spin when there was a difference in temperature between the cambers inlet and outlet valves, and that would only happen if someone decided to use some fuel whilst driving. Otherwise the contained compressor chamber wouldn't spin like a Thermal Combustion Engine and would have as much significance as a pipe to the Compressed Air Engine

Another method of increasing the the potential of the CAC thermal Combustion Engine would be to trade some of the pressure of the CAC's in return for capturing volumes of atmosphere in front of the car to be used as expansive mass when fuel is injected into the chamber.

That would mean the car would have an air intake supercharger at the front of the car that would be powered by the CAC. Some clever pressure pipping switches would have to be invented.

Both the air from the supercharger and the CAC air spinning the supercharger would eventually wind up in the same place, being the thermal combustion engine if fuel is injected.


An example of a perfect Engine would be an Engine that utilizes potential energy without wastefully expelling energy as heat and pressure. If every bit of potential energy like CAC and Thermal Combustion energy could be contained to the engine and completely converted to mechanical energy you're cars exhaust would blow a gentle room temperature breeze from its rear.

I have read and re-read this and I still don't get it.
Are you wanting to power the air motor with a ram jet?

Hi All,

quote from your site
>>Scientists and engineers accept the possibility that the current understanding of the laws of physics may be incomplete or incorrect; a perpetual motion device may not be impossible, but overwhelming evidence would be required to justify rewriting the laws of physics.

and

>>The drawings and calculations of the Uzbek student have already been sent to specialists from Germany.

And their reply is ,,

You partly got it, a small ramjet that heats up CAC gas in a contained chamber. It just increases the temp of the pressure gas entering the Compressed Air Engines that spin the wheels of the car. Thermal Combustion engine isn't a flame throwing jet car. Propulsion is completely from the wheels traction drive.

These guys are close to having something great.

If the new connecting rod design would also support the use of flex fuels you could fill up with what ever is the cheapest that day and run the motor until the air tanks were full and then switch over to air. I think they can do ~ 280 kilometers on a tank of air. so idle the motor on fuel for 2 hours on Saturday and go all week to work on air.

The Thermal Combustion Engine could conceivably have two chambers that increase the pressure to the spinning wheel traction apparatus.

1)To begin with the car would run on cold Compressed Air.
2)A small ramjet 31 cm in length with a turbine centrifugal compressor could intake large amounts of expandable mass(atmosphere in-front of the car) and with the heat of that combustion of injected fuel greatly increase the the sum total of gases both the CAC gases it heats up as well as the pressure of the ramjets hot thrust within the thermal chamber.

Like you said small ramjet turbine could have it's spin momentum swapped to compressing Air to refill the CAC's at -150 degrees pressure to cons eve power.

There are some problems, Air Compresses very quickly at -150 degrees Celsius however Air has impurities like CO CO2 NO2 SO2 SO3 that have to be removed by some means from the CAC re-chargers because these gases become solid grit friction in the liquefying compressing CAC recharger.

Whatever, solids have mass beyond compressed gas and it may be possible to angular momentum spin the barnacles of frozen solid impurities away from the moving parts. Alternately keep the moving parts beyond the freezing points of the above mentioned gases so that they don't stick and jam the CAC recharger. The method to do that perhaps would be to periodically at regular intervals blast the insides of the recharger with hot gasses from the from the ramjet to melt the CO CO2 NO2 SO2 SO3 frozen solids from the moving parts in the CAC recharger

Just a thought,
The air motors that I have read about need a full tank pressure of just over 3000 psi. Could your ram jet do that?
