There is some info on the lee rogers car motor here: Roto Verter

Here is a really cool book this air site has on his download pagehttp://www.aircaraccess.com/pdf/cons...20I%201-50.pdf

It is by George Constantinesco the great researcher into pusled energy like jackhammers, and the great torque coverter on rexresearch siteGeorge Constantinesco: Inertial Transmission (US Patent 1591471 etc)

Thanks Aaron.
Ive always loved the idea of compressed air for cars. The French car is supposed to be build in India this year
We will see. You know how these things go

A car that runs on air, in India soon

Sykavy,

Yes, this IS an excellent site. I have corresponded for over three years with the person who put this site together. His name is Scott Robertson and he currently lives in The Philippines. It is a treasure trove of information on how to gain free energy from compressed air. The most important fact to realize is that the very act of compressing air yields free energy. This happens because, according to the mathematical formula PT/V, 100% of the energy required to compress the air is converted to HEAT, but then you also have the compressed air that can produce mechanical energy when it is expanded again.

A home heating system that uses this principle was patented in 1930 and is available for download here: THERMAL PLANT - Google Patents

This is real, free energy, right under everyone's nose.

Good work, Sykavy!!

Peter

Peter, that is a very profound concept!

Aaron,

Yes, the implication is, if you conserve BOTH the heat and the pressure, in one simple compression stroke, you have more energy available than you started with. The problem with compressed air systems is that they get rid of the heat immediately, primarily because it is building up SO FAST.

A Diesel Engine uses this "heat of compression" to ignite the fuel to initiate the power stroke. Rudolf Diesel's original engine was 75% efficient, primarily because he used such high compression. It was also the original "bio-fuel" engine, running on Peanut Oil.

The point is, in long conversations between Scott Robertson and I two years ago, we came to the conclusion that an engine could be built that ran on HOT WATER and the degraded SOLAR ENERGY resident in the ambient air temperature. The machine consists of a high compression air compressor as the first stage and a steam engine as the second stage. The compressed air is deposited in an insulated chamber between the two cylinders, where hot water is injected. The "heat of compression" boils the water, so the total temperature of the system goes DOWN, but the pressure goes way up. This mixture of hot air and steam is dumped into the steam engine side and converted to more mechanical energy than is required for the compression stroke. The exhaust is air, steam and hot water. The steam is condensed back to hot water and all of the hot water is recycled to be used over and over.

The machine can be thought of as a "SOLAR STEAM ENGINE" that does not require a boiler, or even for the Sun to be out, for that matter. It can also be thought of as a "COMPRESSED AIR MOTOR" that does not require a tank of compressed air. It is really a HEAT ENGINE, that uses water as the working fluid and runs on the heat in the ambient air.

Oh, and by the way, the heat in the ambient air is the ultimate energy source on a WARMING PLANET!!!!!

Keep thinking.

Peter

PS. This engine design and theory is conceptual. Neither Scott nor I have had the resources necessary to attempt to build one yet.

thanks Peter for the info. such a simple thing that just hasn't been explored enough.

One of the articles on the website above said that airtrains were common in coal mining and especially through out Europe in 1920's -1930's.

An inventor Charles Bowen Hodges came up with a way of using the compressor's extra heat to expand the air.
patent:INTERHEATER FOR COMPOUND COMPRESSED ... - Google Patents

Here is an elegant ( even beautiful) air engine very efficient. I think it is a much better design than the French one that India plans on producing


www.engineair.com.au
"We have verification of its performance
We have patents issued
It has outstanding efficiency
It has constant high torque
It has low parts count
It has low number of moving parts
It is compact and light
It has virtually no friction
It has virtually no vibration
It has smooth speed control characteristics
Only 1 PSI of pressure is needed to overcame the friction
THAT'S CORRECT ONLY 1 PSI !!"

If there was some way to put an efficient compressor on board !WOW!!

Sykavy,

Yes, the diAngelo rotary air motor is the best one out there. We contacted him a few years ago, and he knows that compressed air has OU potential. The best compressors are the Copeland Rotary Scroll Compressors. Used mostly in large AC units, they are between 20% and 30% cheaper to run for the same work.

All that is needed to build a self-running car, based on this technology, is a few extra million$ and a couple of years to work out the bugs!

Peter

Air is so amazing!! I don't know how many people have heard of Tornado in a can
Frank Polifka calls his Windhexe machine "Tornado in a Can". It safely harnesses the enormous power of a funnel cloud in a small mechanical canister. The efficiency with which it can pulverize a wide array of items defies conventional physics and invites a new model to be constructed to explain how vortex energy operates. Directory:Tornado in a Can - PESWiki

The patent doesn't have any pictures. I wonder how it works? if it is cold and hot air like a tornado?
Still air is amazing.
I always thought why would we want to bring the sun to earth with fusion when a tornado or a huricane has more than enough energy for us to use.

Guys, there is a lee rogers compressed air/RV concept at the end of this compilation. Thanks for the education Peter

http://panacea-bocaf.org/files/Advan...evelopment.pdf

Peter,

The compressors in the AC units are powered by ac...

Why not connect the compresser (auto ac unit) to a serpentine system...
Motor Briggs 5 hp...connect air lines pull start cord or provide a start tank and run the engine alone.

You could possible connect a generator in the serpentine system and have free energy yes...

Just asking...I don't know alot about compressed air...seems to be doable

Rod

Have you check out the website? It should answer most of your questions about compressed air.

My first thought is that by putting another load on the engine only adds the the the entire load of the motor. Compressed air isnt magical. It still obeys the laws of energy; you can't get out more than you put in but in a special way it can be used similar to a battery that stores solar energy. It doesnt store the energy itself but can be used to collect the energy (Heat) that surrounds it. There is a lot of thinking and gadgetry that must go into organizing it the right way to get OU.

Compressed air has potential but it can be pretty complicated too. This is the reason we don't have air cars everywhere it isn't as simple as it sounds but that being said it isn't as complicated as some other means of energy.

One way air motors could be OU simply; is If you had a solar/windmill compressor that worked all day (and night if there is wind) you store all that compressed air in tanks and then run a generator on that. The compressed air would replace electric batteries and compressed air can be stored for long periods of time with no loss of potential energy; while batteries charged by solar energy would store the energy but start wear down over time.

thats my thought but check out the above website to understand the great things the compressed air has done and can do.

Windmill compressed air is a VERY PRACTICAL solution that can be done now.

Yeah! that was one of the reasons I was so excited about the Indian (French design) air car. Even if it was relatively expensive to make up such a solar/wind system to store at home, it would be worth it. You could fill your car at home!

Ive been reading a lot about air lately and here is a tid-bit that doesnt have any numbers but Scott Robertson is the GUY when it comes to compressed air and I trust him ( as well as Peter Lindemann's endorsement):

"It takes less work to increase the pressure of a volume of air from 100 to 200 psi than it would take to increase the same air from 0 to 100 psi. This can be verified by looking at any air compressor power consumption chart ever published. It is the rationale behind the closed cycle pneumatic power plant, which can do more work with smaller machinery.

Any chance to boost the pressure of already compressed air instead of compressing atmosphere will lower the relative size of the machinery needed to do that task, because more energy per unit volume of compressed air is handled by a booster than by a normal atmosphere compressor with the same displacement."

So smaller compression in a series of compressors could be more efficient than just using one compressor. Very interesting

That is an idea..... are you saying put the compressor on the windmill itself?

That sure would kill voltage loss in the lines, and you could cheaply run the air to a tank a VERY long way away.

I have been thinking of buying or creating a tank to store compressed air with a safety valve that would kick in if the pressure got too high. The ideas of heating here look outstanding. But a windgenerator hooked directly to an air compressor, I love the thought of that idea.

I'm looking into solar water heating options and I know they can get so hot that there are relief valves to blow off steam. Anyone know of a simple steam powered generator that can be powered by the blow off? Just thinking out loud.

you could try this siteGreen Steam Engine Home Page
it looks really cool and he will sell you a kit and if you call him he may come up with a bigger design. He has one video of him with a steam powered boat!

I just posted the following in the electric car thread but then regretted it because it was off topic and really belongs here since it has to do with pressure. I just get so excited sometimes about this stuff.

The Inertial Storage Transmission (IST) that Carman developed bypasses all these problems by storing the engine's energy in high-pressure fluid. The fluid is pumped out of a reservoir by a small gas engine, into an accumulator at high pressure, which holds the fluid like a super-soaker holds water. Then, based on acceleration, more or less high pressure fluid is fed out of the reservoir through a hydraulic motor (like a turbine) to drive the wheels.

The system works almost identically to current hybrid electric systems, with some major advantages. First, it's cheap; hydraulics are a common technology with low service costs and cheap materials. Second, there are no expensive batteries or electronic systems to damage. And third, energy loss in pressurizing the accumulator tank is much less than for charging batteries.

Vincent Carman: Inertial Storage Transmission

Carman isn't alone. At least one other group of inspired experimenters has found a way to use hydraulics to vastly increase an automobile's gas mileage.
That group is a class of advanced students at Minneapolis, Minnesota's Hennepin Vocational Technical Center. And under the guidance of instructor Ernie Parker (and without ever having heard of Vince or his Inertial Storage Transmission), the class recently designed and built what they call a "hydraulic storage transmission".

Does it work? It sure does! As the students have already demonstrated, when their special drive train is coupled to a 16-hp Tecumseh engine, installed in a Volkswagen chassis, and covered with a Bradley GT body ... the resulting one-of-a-kind automobile will travel (at speeds up to 70 mph) an incredible 75 miles on a single gallon of gas.

That's impressive, especially when you remember that the HVTC fuel-stretcher was entirely constructed from off-the-shelf components that are readily available to any home mechanic in any part of the country. The sleek little automobile contains absolutely no exotic technology or hardware at all.
THIS CAR TRAVELS 75 MILES ON A SINGLE GALLON OF GASOLINE!

But wait there is still more!!
The teacher from the tech school (second linked article) still seems to be at it. I did a little searching and presto!!:
http://www.hydraulicinnovations.com/index.htm
Pretty cool he didn't give up!!!

From my reading the compressor would be on the windmill itself or mechanicly on the ground. It is already being used on a large scale in Germany electro- power plant for 25 years.http://www.uni-saarland.de/fak7/fze/AKE_Archiv/AKE2003H/AKE2003H_Vortraege/AKE2003H03c_Crotogino_ea_HuntorfCAES_CompressedAir EnergyStorage.pdf

But that being said I think it would be more practical to have one for each home. One draw back is the noise windmills can make it drives some people crazy.
There are a some patents that say that windmills and compressed air is the way to go since the speed the turbine spins isn't so important to compress air as to generate electricity.

One idea is to put the compressor underground and blanket the compressor with water to absorb the heat generated by compression and use that for the hot water for the house/heating and the air tanks underground plus airconditining too since expanding compressed air could cool the house.

Windmills have been grinding grain and pumping water for a long time on small scale and should be easy enough to have it turn a small mechanical air pump on a residential level.

Hi Aaron
Did you check out that steam engine link I gave above? It seems great for what you want plus he supplies the difficult parts. Again it is with in our reach Now!

and again from above this link
http://www.hydraulicinnovations.com/...20machines.htm

He already has a 70 miles to the gallon car and is selling a DVD on how to do it
or maybe he does it for people too but it is NOW! It isnt something we need to wait for. This is exciting.

ps could you take my off-subject post on the electric car thread off, please?

Thanks for that steam engine link! Actually, that was the exact one I was thinking of but couldn't remember what it was called...a very neat design!

I found a forum that discusses Hydraulics and some talk about air compression.

These are serious guys that make off road vehicles but they use hydraulic energy like Carman (see post# 20 above) to run them.
(they also make some really cool videos! Like a kid's car the goes about 30 mph in the snow !)

This may be a good place for contacts for people on this forum. They may help develop other possibilities like the Lindemann motor.
They also have a DVD it looks similar to Peter's except they explain the secret of hydraulic motors.

Hi,
I don't know is you have seen this, but I uploaded a video where you can see two enthusiasts that are working on compressed air engines. One man is in France and converts typical internal combustion engines to run on compressed air. But the other fellow lives in Australia and has invented his own air engine design - very good video.

Thank you

Thanks Jetijs. We had the 2nd video on post 9 but not the 1st one thanks!

Okay i spoke to that guy in November he was heading over to China to seek investors - no luck. He is local to me and asks for an NDA.

Now mean time, what Aaron said is right, look at the way this guy compresses air.

I got my brother interested in this air engine concept. He is very experienced in internal combustion motors and we think that we could easily convert a small engine to work on compressed air, just to see how it performs. We are thinking that an old lawnmover motor could be used for this. We wont use the heat from the air compressor, just try to make this thing run on compressed air. I will keep you informed

Super Glad to hear it!!
There are different levels of air cars.
1.Hybrid air cars carry a gas-powered engine and compressor on-board

2. Conventional air cars, such as the pneumatic locomotives and the French and Australian in your video link, which stop at air stations to refuel.

3. Self-fueling air cars are powered by solar energy and can travel non-stop until they break or develop an air leak. Such cars are experimental in nature, and getting an inventor to give up his secret is harder than figuring it out for yourself. Hint: absolute zero (if the sun went out, for example) is 460 degrees below 0 degrees Fahrenheit

Here is one, the Neal patent#: 2,030,759, that blew peoples minds and he mainly converted an old car into an air car ( from an interview of his son) but the compressor was the key. He could fill his tank at the same time he used the air. the Patent office wouldn't approve it because they called it a perpetual motion machine but Neal (the inventor) flew to Washington with a suit case example in his bag to prove that this idea worked and it wasn't perpetual motion the energy came from the ambient air. They saw it work and gave him a patent but the patent is missing details on his "magic Valve".

How did he fill the compressed air tank with normal air? This is the mystery.

-------------------------------------------------------------
Here is some info below that may help your brother:

Does anyone have feed back on these pumps supercharger pumps(US patent #2159278 and 4789299)? How efficient are they? If anyone knows anything about them could you explain?

check out these patents:2159278 and 4789299

Here is the Neal patent: 2,030,759

You have to put these numbers in this search engine:

Here is an idea I had about Neal's "magic valve." There is pictured two valves that put air into the tank. Could these be spirals pumps ( from the above patent or something similar to it?) look similar to the valve pictured? What he may have done is connected two valves (with spiral pumps as above) with a long shaft that went thru the Neal tank on one long central shaft to the motor. Maybe all they did was erase the drive shaft from the motor going thru the tank to the valves.

REMEMBER:
"It takes less work to increase the pressure of a volume of air from 100 to 200 psi than it would take to increase the same air from 0 to 100 psi. This can be verified by looking at any air compressor power consumption chart ever published. It is the rationale behind the closed cycle pneumatic power plant, which can do more work with smaller machinery.

Any chance to boost the pressure of already compressed air instead of compressing atmosphere will lower the relative size of the machinery needed to do that task, because more energy per unit volume of compressed air is handled by a booster than by a normal atmosphere compressor with the same displacement."

Mixing the fresh atmospheric intake with air that is already compressed ( The exhaust from the engine may have a third or more of their original pressure. The pressure used to move the pistons doesn't or isnt completely used because it could end up freezing the engine with ice etc...). By recycling the exhaust, there may be only "1%" ( or a little bit more) of the compression work left to do, which could be easily accomplished with less resistance and less heat.
