Aircar technology:PNEUMATIC OPTIONS

[sykavy]

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

Wow...

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

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.

steam generator?

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!!:

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/...rgyStorage.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.

small windmill air compressor

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?

steam engine link

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!

[sykavy]

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 a link that may help your brother to understand the great things air can do!
Equalization Engine, Luther's Secret for Self-Fueling Air Car
Pneumatic Options Research Library

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.
