I have to start this thread with an update, and follow with a complete explanation of what it is, and how it works.

UPDATE:  Procured about $500+ in Fittings and copper to make 3-way Super-Heater/Super-Coolers, using LIQUID to LIQUID Heat Exchange, and in a method that allows 20 CUBIC FEET of expansion per second while still flowing freely and unrestricted (like the wave-plate exchangers).

After Dinner, I will explain HOW it works and WHAT it is.

Aurora Energy Technologies LLC is the joint venture that is bringing this technology from the drawing board to reality.  All donations, contributions and help is appreciated.  This technology is worth absolutely nothing if it is never used.  Let's make it happen and use it to free us from the grips of OIL GREED.

Yes I would definitely be interested in that plate heat exchanger you have.  I'll be in Palmer this weekend sometime.  If not, then next week early in the week.

Maybe I could stop in sometime and help out for about 6-8 hours on your project?

this sat i'll be around for a bit I might be able to get a baby sitter for baby.  Everything has come to a hault though when donations became slow.  I'm so close to having many systems that work very well and won't even void the warranty of your vehicle.  Real world inventions.  None of them are new really they use ideas and theories that people thought of many years ago i'm just simply the doer here.

How it works:

The refrigeration cycle is the basic main components of the Aerothermal Power Generator.

Condenser: This is where the heat is REMOVED from the refrigerant and the refrigerant is allowed to CONDENSE back to liquid state.

Evaporator:  This is where heat is absorbed by the refrigerant, and the refrigerant is allowed to EVAPORATE, and change from liquid to gas, much like boiling water.

Pump:  This keeps things moving in the right direction.

Oriface: Tiny hole where the refrigerant is 'sprayed' into the evaporator, generating an absence of heat, thereby absorbing the heat, boiling the refrigerant and generating gaseous pressure.  

Accumulator:  This is the 'reservoir' per say.  Commonly coupled with a dessicant and filter.

Now, the system works like this:

4 cylinder engine, modified camshaft to make the valve action as such:
Every time a piston moves from TDC to BDC, the intake valve is opened.
Every time a piston moves from BDC to TDC, the exhaust valve is opened.
Every time a piston is "dwelling" the cams are in 'overlap' and the lobes are either ramping up or ramping down.

The end result is a 4 cylinder, sealed, unvented STEAM ENGINE, of the SINGLE ACTING TYPE.

(I am fully aware of the benefits of DOUBLE ACTING, but unless ANYONE, ANYWHERE, with a good source can direct me to a place where I can PURCHASE a SEALED double-acting steam engine that is rated for refrigerants, this double acting vs. single acting steam engine topic is DEAD.)

The refrigerants will provide power to only 2 of the 4 cylinders.  The 2 cylinders are 180 degrees offset timing of the crankshaft, and thereby SELF STARTING.  The exhaust stroke of each of the 2 power cylinders provides the 1st stage compressor pulse and flow to the 1st stage condenser.
The output of the first stage condenser is then fed into the 3rd cylinder, providing the second stage compression pulse and stroke for the second stage condenser.  The output of the 2nd stage condenser is the input for the 4th cylinder and becomes the 3rd stage of a 3 stage pumping action, and finally goes through the 3rd stage condenser and finally to the filter/ drier, and the accumulator and into the oriface tube to the evaporator where the process repeats.

By the use of R744, I do not need to ever reach liquid state, because the expansion is very close to exponential and contraction is the same.  

In the design, the system merely generates an absence of heat, and uses that heat to generate refrigerant pressure to drive a piston and push the pistons down, driving a crankshaft, thereby with the capability to power a generator, then dumps this heat with an even greater efficiency to a structure, building or even back to the out-doors.  

If this system were installed to generate power from a river, the condensers would need to be placed UPSTREAM and the evaporators DOWN-STREAM.  This flow pattern makes for an environmentally NEUTRAL thermal change in the water, EXCEPT for the power extraction.

This is why I would suggest using the ATMOSPHERE and not a stream or river.

The incoming air is X Temperature or XT1.  The output temperature is XT2.
The conversion of heat to work in BTU equates to watts available.

So the Incoming air to outgoing air temperature is such:

XT1-BTU=XT2

That's the simple end of things.  You can over complicate this a bunch, but the simplistic nature is what makes it work.

I will post pictures soon.  I have to upload from camera (when I find where I put the darn thing...) then to the site.

Thanks for your patience.

Here are some of the pictures from the project.

First picture is the flow schematic of the Aerothermal Generator Cycle.

The second is the camshaft profile showing the intake cam and exhaust cam angles in relation (proper) for the function desired to operate.

The third is a separate of the cams, showing what a single valve cam for each of the intake and exhaust cam profile should look like.

The 4th and 5th pictures show the magnetic valve system assembly view.

More pictures coming soon.

Here is the control schematic for the Magnetic Valve system used in the Aerothermal engine.  This system is used to dial in the right cam profile, and can be used continually for the long term.  The engine will not get hot, and results in the answer to the 'Curie Effect'- named after Madame Curie, of Poland, for the permanent damage to a permanent magnet caused by engine heat.  Keep in mind that the engine WILL NOT GET HOT.  It will actually ABSORB HEAT.  

Thus negating the Curie Effects on the magnets, the cam profiles can be either mechanical or electric.

please format your pictures better.  Makes this difficult to read.

Ok,

After getting an ungodly expensive quote...of $10K bucks PER CAMSHAFT....I have found a cheaper alternative.  Ford uses in certain models a modular camshaft.  The lobes of this camshaft can be pressed off and back on.  This is important.
I will still require the use of a DOHC 4-valve per cylinder engine, and I procured a candidate for free. 2008 Ford Escape 3.0 Vulcan VIN Code 1 engine.  

The camshafts should be done tomorrow, but I am waiting on the piston rings and bearings right now.  I have some finances, but still working to provide the remainder.  Suggestions? Donations?

Anyway, since it's a V6 engine, I will have to redo the adapter plates for the intake and exhaust, while still achieving the same amount of heat exchange ratio required to do the job.

Should be fun to say the least.  SOON!!  I hope to be test running it!!
