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.

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'
momentito
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.
momentito
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
momentito
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.

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. smile.gif

These guys are close to having something great.
http://www.theaircar.com/howitworks.html

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.
momentito
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?

The air engine has been around for decades. You can even purchase a conversion kit for a V8. This is where I got my idea for my evaporation engine...But, I won't get into the details. Think about it. huh.gif

Another improvement to the CAC Thermal combustion engine to make it completely `GREEN' is to use Hydrogen as the inject-able fuel when someone wants to use more power than the regular `Compressed Air Cylinders' can provide. The emissions would be pure water vapor. And to put the cherry on the cake the CAR can be a domestic plug-in that recharges when you plug it in at home and the electricity can be used to super heat a pipe from the CAC's that would increase the pressure of the compressed air giving extra power. Given that your all possibly rev heads and if your going to inject whatever fuel to heat up the pressure coming from the CAC's then you could have option of fitting a `Compressed Oxygen Cylinder' amongst your CAC's

Perhaps instead of using the electricity to super heat the `Compressed Air' there could be more potential power to simply charge some of it with energy to give it pressure and velocity (Ionize and electrically accelerate the gas through the `Compressed Air Engine' )?
PIATLAS
Maintaining the pressure in your CAC when Compressed Air pressure is running low can be solved in two ways: Use lasers to heat up the temperature of the remaining Compressed Air in the CAC as-well to progressively electrically ionize the gas in the CAC to increase the pressure. Thus the power of the car wouldn't be completely dependent on the volume of gas in the CAC as stored potential energy but would have its potential energy increased with electric ionization as-well as thermally with lasers providing constant pressure even when down to 10% Compressed Air.

Why use air? Why not use a chemical in a closed system? One that flashes into vapor when it reaches a certain temperature, and can be condensed back into liquid to repeat the cycle? This is the idea behind my evaporation engine. Think about it.

Because air is cheap to compress, very clean, safe, shall I go on?

"Because air is cheap to compress, very clean, safe, shall I go on?"

So are the chemicals. In fact, they are easier to compress than air. No exhaust at all, no high pressure tanks.

Well let me put it this way:
The village idiot can plug in an air compressor, but I don't think grandpa will want to fool around with chemicals. or pay someone else to do it for him. Then there is the transportation, storage and disposal. oh yea what happens to them in a crash? AND the exhaust from air gives you air conditioning (for Free). Simplicity (KISS). Why go for the Rube Goldberg design when this is so easy? wink.gif

Paul,
I guess that you don't know what a closed system is. There will be no messing around with chemicals, nothing to plug in, no storage, transportation, or disposal of chemicals. Also, this system will work as an A/C better than any air exhaust could.

I do understand what a closed system is and I know that in automotive applications there is no such thing. (in real world applications that is) the closest thing to a closed system on a car is the A/C system. And if it were truly "closed" you wouldn't see A/C repair signs on every other corner. The chemicals will either leak out or deplete themselves and need replacement. that is providing it doesn't take more power to mix, expand and condense them back into a liquid than the power that you get out of them. However, with that said. I'm open to learn more about your engine.

I was Wondering, Wouldn't the chemicals brake down?
How many cycles could be possible using a chemical?

And about the mechanical energy used to compress air,seems like you must have compressors running everywhere to meet the needs.

Using the energy direct instead of indirect has always been more efficient.

Right now nothing beats having meat. Gasoline's got the muscle to push pistons around.
I don't like it,but the system is so well established now, that oil is in some form everywhere.
Look in your garage, chances are there is some.

I haven't read about your evaporative engine so I'm unfamiliar with your principal.
However because your using the words evaporation and closed system.

The recipe of ingredients for such a system would be the following:

1) Pluggin Rechargeable hydrogen-fluorine fuel cells to provide power
2) A CO2 LASER to quickly and variably heat up a steel cone
3) A water injection system that spays onto the tip of the cone producing steam at high pressure
4) An steam analogue to a CAE
5) A alcohol based condenser to recycle the steam.
5) A thermopile semiconductor to convert the heat captured by the refrigerant alcohol into electricity to recharge the fuel cells.

Again, here is what I think to be the best motor for many,many applications.
However I think that the ultimate application for a car would have one of these motors at each wheel with a computerized traction control system. With a small battery bank to power the electric system IE radio, lights, horn, windows, wipers and such.
