Directory:Generator from Ambient Air by Kim Zorzi
Kim Zorzi of Ultralight America has designed and is preparing to build a 100kw power system that he purports will run on a multicylinder air type engine. The system is different from previous ones in that it has a regenerative tank. Zorzi alleges that this will enable the system to repressurize itself. It repressurizes the high pressure feed from the low pressure side for continuous running. This would be a non-combustion system, using no input fuel to run. Theoretically, the system is driven by the temperature of the ambient air which is provided by the regenerator tank, which gets its power from the generators.
Two NEC members deem the design to be not feasible. Zorzi give a rebuttal. Allegedly based on a working device built in the 1980's by Terry Miller.
A new concept is presented to provide electrical energy from ambient heat, ideal for servicing places unaccessible by power lines

"I have built a prototype Air Powered Generator. The system has taken me nearly 4 months to build but I am happy now that the system is running. There has been many design changes that have come about, but one that you would be very interested in is the one where as I have been able to make the system produce its own energy while it is producing 40K watts of energy output.
This system stands on its own without any outside fuel sources needed to make it run.
So now as I posted before about the regeneration process, it does work and I have proved it. At this time I am installing a control system that will police the temperature and the pressure so as a safety precaution to keep the system from over pressurizing the storage cylinders.
A larger corporation has purchased the rights for this from me already and I will turn this system over to them in about 2 weeks. They will unveil the power system in Florida later this year after all paper work and patents are in place.
Attached is a photograph taken last month to show you I speak the truth. Although I don't reveal everything in this photo, it is enough to show that it does exist.
Please do not publish this photo or send it to anyone else until the system is unveiled later this year. I have a full pictorial history of the buildup process plus a complete set of engineering documentation in order to reproduce more systems later. You will be utterly amazed at some of the new technology I have been able to incorporate into this system. It is so quiet when it runs you can cover your eyes and not hear it. The only sound is the lashing of the gear teeth. An once the cover is installed not even that will be heard. It can run 7 days a week, 24 hours a day, rain or shine. It does produce enough torque to power (4) 40kwatt generators. I will be doing a torque test later in Florida to justify the output.
Thank you everything and I will send you some video later to post along with more information."
This is not a patented technology.
How it Works
Electric Power Generation with Air Engine
The 3-D AutoCAD rendering shows a concept of design, capable of producing 100kw of electrical energy. A design only using two generators to produce 50kw is more practical for the normal household and of less cost.
Torque required to produce power from two generators is only 720 foot/lbs. Add 2 more and we go to 1440 total ft/lbs.
This air engine design can produce 1500 ft/lbs with ease. By simply regulating the pressures by computer control valves, more torque can be added to the system. Adding a regenerator to the pressure system can double the torque output as well. Something like a turbo boost. So four more generators could be added to this system.
The air circulates from the high pressure cylinder storage tanks into and thru the air engine. The last cylinder acts as a double acting type and compresses the air thru the regenerator and into the low pressure storage tanks. The power required to compress 1 cu/ft of free air is .378 hp up to 2000 psi.
In other words, the power required to recompress compared to the amount of torque received is very small.
In the Regenerator, the heat is inserted back into the system and this heat is controllable to produce more pressure. The amount of heat required is again a small amount compared to the ultimate gains. The low pressure air is ultimately fed back into the high pressure tank. A high pressure electrically operated compressor is onboard the system to insert air into the high pressure tanks if a certain amount of pressure loss is felt in the system.
The Power of Air
The power achieved from the principles of expansion over combustion is far greater. Expansion can be manipulated to produce more or less torque values and at a faster rate than its counterpart opposite. Temperature and pressure go hand in hand. Temperature increases and so does pressure. The air engine absorbs the ambient air temperature and the pressure decreases as it moves thru the system. But this pressure is still capable of producing torque down to the last cylinder. To revitalize the pressure system is to add more temperature. The air engine can be designed into a (AIP) Air Independent Propulsion System.
Electrical Power Costs
Zorzi is offering to build a 100 KW system for $ 20,000.00 or a 50 KW system for $ 14,800.00
To purchase a 50kw system of comparable value will cost upwards of 35-50 thousand dollars. Although the supplied generators are only for emergency use. Heavy duty, long term generators that can run for 10 years are a tad more expensive but much more reliable. This puts the price of power generation to about $60.00 a month for the smaller unit when operated for 10 years. Making the systems portable by mounting them on a nominal trailer can create the electricity needed anywhere, anytime.
History of Air Engines
The use of air engines in the late 18th century and into the early 19th century was a new budding technology. Most of these systems were big and bulky, but they worked and got the job done.
One of the most promising researchers and inventers of air technology - and his death was a great loss to our society - was Terry Miller of Joplin, Missouri. Terry designed a multicylinder air engine that created multiple torque loads from one shot of air. Our colleges teach that air is inefficient and is not practical. But Terry proved them all wrong.
Terry’s engine design is shown here.
The picture shows the engine assembly before it was mounted into an automobile over 20 years ago. This engine ran Terry’s car for several hours at speeds of 45 mph. The car somehow managed to find its way to the crusher by the action of some unscrupulous individual. This auto should have found its way into a museum instead to show how technology can be changed.
After reviewing the calculation of Terry’s design, a new plan was formed to create a home electrical generator system from this technology.
Terry’s dream was to create a ZEV (Zero Emission Vehicle) and this dream could have been realized had he lived longer.
Researching the patent base for air engine technology to run electrical generators has turned up no results. That is because most technology advances was used toward transportation purposes.
Coal Mines used air locomotives to haul coal out of the mines.
Germany used Air Locomotives to criss cross their country when the petroleum resources ran low. Alternative avenues were developed and again this technology was scrubbed from history.
Companies like H.K. Porter that produced a large number of coal air locomotives somehow misplaced the drawings concerning the air locomotives, but still retain the original drawings of the steam locomotives. One has to ask questions why this is.
David Schwarz (1852-1897)
A Croatian aviation pioneer, he constructed the first controllable dirigible airship in 1896. Even though history writes a different story, Zorzi uncovered evidence to prove David Schwarz' airship ran on a self fueling air type engine. David's death was in January of 1897, but his airship was seen in the U.S. in April 1897.
Reviewing pictures of his engine clearly shows it was not a combustion engine as stated but a multi, double cylinder aluminum engine designed to double pump expansion and compression at the same time. His engine was mounted inside the hydrogen envelope. No one in their right mind would attach a combustion engine in that location, yet historical accounts state so.
An additional comment by Zorzi - 12 March 2007
Many people will not fully understand how this system operates. But those who understand thermodynamics will grasp this concept. I have already been met with fierce opposition and I expect that. The engine runs and I have a video to prove it. The engine can create enough torque to run the generators with ease. The regeneration process is what is puzzling to most people. When temperature goes up, so does presure. The engine syphons all the temperature from the air, dropping the pressure down in each cylinder, till the last cylinder is only 40 psi pressure. So the flywheel momentum easily compresses the remaining pressure thru the regenerator tank and into the low pressure tank storage. But after the cold air enters the regenerator, it extracts the warmth from the fluid and expands back to 76 degrees and also expands its pressure too, as it refills the tank.
Some small pressure loss is realized thru the pig valves, and that is why the onboard compressor station is there. The compressor operates on 5 hp and is capable of producing 5 cu. ft per minute up to 5000 psi. The storage system contains 450 cu feet and the engine consumes 1.23 cu feet per minute. But when you inject the rejuvenated air back into the high pressure tank thru a check valve, the system will perpetuate itself. As the high pressure tank drops in pressure, the low pressure tank is gaining in pressure till the low is high, and the high is low and the check valve opens. I'm not saying it will run forever, but till the prototype is actually test run will I realize the full potential.
Built by Terry Miller in 1980's
On March 15, 2007, in response to a request to elaborate the statement above: "I have a video to prove it", Kim Zorzi wrote:
The air engine was already built by Terry Miller in Joplin, Missouri and installed in a Chevy Chevet in the 1980's.
The performance data concerning the engine was already outlined by Terry before he passed. This performance data corresponds with my calculations. Terry did not get as far as to create a re-generator for his automobile.
Terry operated his engine in a car, I will operate mine to run (4) 27.5 kw generators as shown. In referring to a prototype, I was referring to my operational unit that will run the generator system.
I also retrieve all information for building the same engine as was built by Terry. I have already purchased the components for the engine and working with a fab shop now to constuct the framework. Also, the tank systems are being designed and fabricated in California by a scuba tank manufacturer.
The system should be operational by summer. My biggest expense is the generators which will cost about $2000.00 dollars each.

The following comments were made by New Energy Congress members.
Not a Feasible Design
On March 9, 2007, NEC member, Robert Indech, PhD PE wrote:
As I understand it, mechanical energy is derived from the high pressure air chambers, the output of which feeds to the low pressure chamber. So far, so good. However, a second cylinder powered by this compressed air acts as a regenerator which recompresses the air and feeds it into the the high pressure chamber. Further, in the regenerator, heat is produced and inputted back into the system to produce higher pressure.
As the inventor noted, this system design is a perpetual motion machine, with no need to input fuel, and with a constant power output.
I firmly believe that when the detailed thermodynamics of the process is examined that it will be found that the energy required to operate the regenerator will exceed the mechanical power generated by the system in total. Further, that the overall system's efficiency will actually be substantially less than 100% as waste heat will be evolved by the mechanical motion as well. The amount of energy required to repressurize a given quanitity of a working fluid is critically dependent on the difference in pressures desired, unlike the statement there: "The power required to compress 1 cu/ft of Free air is .378 hp up to 2000 psi."
Unfortunately, the design is not a feasible free energy generator.
Also on March 9, 2007, NEC member, Ken Rauen wrote:
I agree with Robert's quick assessment. Higher pressure does not indicate anything regarding an energy balance. Hydraulic pressure multipliers have been around for decades, yet they are not a source of net energy.
I have asked the inventor for detailed reasons why he thinks it is a PMM2. Until I see details presented by the inventor to address this crucial claim, I remain unmoved, but open to hard evidence, either detailed theoretical or experimental.
On March 10, after Kim Zorzi provided additional explanation, Ken Rauen wrote:
My assessment remains the same. Even if Kim submits the pages of calculations he has, I unfortunately do not have the time to wade through them, so I await his experimental proof.
From what is provided, I do not see any unusual processes going on that creates an exception to the 2LT. I strongly suspect there is an error or two in his calculations, and I am not going to spend hours looking for them.
- Rebuttal by Zorzi (March 13, 2007)
- How do you know this is not a feasible system?
- You are so quick to disprove this system when you have not even understood how the system works. You have not even reviewed my data or calculations on this subject.
- Time will tell if Im right or wrong.
- This concept proves your theory, that the "Proell Effect" does indeed show merit and that PMM2 does exist.
- This is not the only design that I have that proves its reality and existance. Expansion principals are not as understood as combustion. I guess that an indothermic reaction never existed and neither do thunderstorms.
- My next contact to you will probably be pictures and performance data.
