aussiebattler,

So this is your theory and claim this is Richard Clem design?

Question: where do you expect to get 400+ psi from?

A torque converter is not a pump, transmission need hydraulic pump to move the fluid through the torque converter inner ports. The torque converter is fluid connection, nothing else.

Since you question the mathematics and talked about physics, how do you expect to generate power output?

Here is one of my old videos, showing no pressure is created in the torque converter.

https://www.youtube.com/watch?v=D2L_PBGgHZw&t=122s

The only reason in this test the pressure drop is do to the centrifugal force canceling out a portion of the pump needed to get it running in the first place.

But as it increase in speed, thrust decease also, where do you expect to get a phase change from?

The real reason Richard Clem used cooking oil is due to the high flash point it has. He did in fact use a few hydraulic pumps in his design, this how he was able to get these high temperature and pressure

Keelnet and the founder Jerry Decker, didn't really know how it worked. Even the cone screw design wasn't correct.

Until you get your hands dirty and experiment with real world of physics, you're drawing is just that; nothing and is a insult to those who build stuff.

Thank you for your kind words Tommy. I hope to see one of your devices operating soon as well.
Attached is one of my hand dirtiers showing one vane causing the high pressurs and temp.
thanks for your interest.

aussiebattler,

For those who claim how the Clem engine worked and put simple drawings and paste others to explain their theories, should not be taken as facts.

What is a expert in a field?

Someone who has built many prototypes, or someone who draws picture?

Maybe you can get your hands dirty, instead of explaining a theory.

Too many people on these forums that talk, draw and build nothing!

Experiments always trumps theories!

I suggest you start with a water wheel, it much better then a drawing!

aussiebattler,

This is my experience in working prototype, your design needs hp/rpm's to create pressure. The pressure produce is not free and the output is far less due to the factor of rpm's input vs thrust velocity output.

No different then a centrifugal pump, it take lots of energy to move fluids no matter if it's a volume of water or high pressure of water.

Just look at a pressure washer, do you think your design will create 500-4000 psi? The reason these pumps are pistons instead of centrifugal force impeller is due to amount of force a piston can push the water outward.

Clem engine used 7 stage( could be 7 pistons) hydraulic piston pump for a reason high pressure,temperature and lubrication. This also create the high temperature in the cooking oil, the reason he used cooking oil is the high flash point instead of oils. It is possible that injecting water into the high temperature cooking oil that created a phase change effect. Something I haven't done yet.

I will give you credit of starting to experiment, that's a plus. The question is do you think you're going to create enough pressure to over come input power?

I think this will be a good learning process to start with.

The principals involved here relate to the "venturi effect"


When reduced, yes. The vortices can be described by Inviscid fluid dynamics.

It is important to go back to the beginning.
Set aside (for a moment) the replications of people attempting to understand it.


Look at what was given to us by the inventor.


Look at the description of the device
And what we know about its’ characteristics.


The laws of convection dictate there are areas of hot and areas of less hot
contained in the stream of hot gasses from the burner.


The vortices separate these into a temperature (and subsequent pressure) differential.


This thermal potential is then converted into further rotational force,
simultaneously accelerating the process (to a system maximum) and also
lowering the (average) temperature of the gasses by converting heat to work.


The most interesting aspect of this device (to me) is not what it does or how it converts the heat to rotation, these things are trivial and mostly well understood.


The point of interest i find most intriguing is not even being mentioned here::
most arguments concern the output of the rotor.
But most seem to miss the point that the exhaust gasses (though colder than at the burner) are still well above ambient. If the claim of OU stops at the rotor!?! Where does that put the remaining thermal energy of the exhaust?


I suppose many engines are suspect in this area, have you ever compared the total energy consumed by your car, in terms of the mobility, recharging the electrical systems, and then try to add in all the heat output?
It is estimated (by Carnot) that 50% of your fuel is converted directly to heat losses.
Where does this heat go? Can we recover it? (Seebeck Exhaust Generators used to be a thing)


Exhaust from the Clem engine could possibly boil water after it leaves the machine.
i think if we are measuring efficiency or energy in and out, this should be done with respect to the thermal differential between the gas coming out of the burner, and the temperature of the exhaust.


It has been considered that the Rank/Hilsch device does not follow Carnot Law

We can test this:


By running hot water through a mechanical rotary sprinkler
(the pure rotary ones, not an oscillating sprinkler)


The output water is 2 streams one inside the other.
One very hot, the other very cold.
I’m sure it does this with cold water to a lesser degree though i have not measured that.

What astounds me the most is that commentators on the Clem fail to explain where the energy that gives us 350 hp to drive the car and produces a bunch of heat as well (that we need to do away with ) comes from. Well of course we have heard about the breakdown of the cooking oil but this does not fit with Clem's dialouge.

Hi aussiebattler,

Ok, now you have a very good question.

Lets look at the claim of 350hp, 1800 rpms, cooking oild and temperature over 300deg.

350hp*(5252/1800) = 1021.2 ft/lb of torque is needed at a constant.

This is a lot of thrust and depending on the size, flow rate  and other factors. If it's 24" diameter  spinning at 1800 rpms the velocity needed would be greater then 188.4ft/sec. In fact it would need double that due to load. 188.4 just gets you up to speed, put a load on it and it will slow down to balance out.

So  to be safe, 376.8ft/sec just for the total velocity of the jets.

To generate the thrust and keep the velocity would be calculated by the size of the jets and number of them. This also will deal with how much fluid flow rate is needed gpm and psi.

These are big numbers to deal with, if all starts with what size you plan to build.

I have a hydraulic pump that produce 80gpm@2000 psi/1714 = 93.34 hp needed to move that amount of fluid and pressure.

I still believe that it was a type of diesel effect with the cooking oil to get this much power out of it.

By your explanation it is not so incredible how the motor works but rather how much energy you can get out of a few bottles of cooking oil (even enough to pump it to high pressure as well)

What gets me, everyone is looking for a free lunch, instead of looking for more efficiency. We already see the Prius that get 55mpg, yet we still are looking for a free lunch.

Nothing is free, but it doesn't mean we can't get higher efficiency. In fact if the Clem engine did run off cooking oil, it would have been the most efficient engine today.

It's also possible that he used water injected  into 300+deg cooking oil to create a super heated steam turbine. I have not experimented on this, but we all can see the effects of water mixing in with super heated cooking oil.

As I understand it Clem celebrated a free lunch and I am seeeking a similar meal.
I also wish you well in your endeavours

Hello AB,


Thanks for the document.  The only thing I did not understand from the document is whether or not the outside cone rotates with the inner cone.  My understanding from what I have studied is that the outside cone needs to be stationary.  The friction between the oil at the boundary layer between the oil and the outside cone helps to increase the heating of the oil and thus helps increase the pressure which of course increases the thrust at the nozzles.


Thanks for your efforts and your sharing.

Sorry I misunderstood you at first. No outer and inner are joined for ske of ease of manufacture. I would say that we do not need extra load of friction causing heat . I beleive the heat caused by pressure at the nozzles is all that is needed
I like your work. Seems like we are of one spirit
