Some years ago I was directed to download a file. It may have been a PDF. I was told it was Teslas work that I would not find anywhere else. There was an invention and it's detailed description of a 3 stage reciprocating mechanical amplifier for the making of condensed liquid air. Well as with every time I get my hard drive packed full of rare material it was wiped out and the information was lost along with countless other documents and inventions that I did not have time to memorize or study.
 But that file must be somewhere. I did download it after all. I believe I was using windows 98 or 2k at the time and a dial up connection, so it must have been around 2002? Maybe? Not that it matters, it was just a long time ago.

Anyway, does anyone on here have that information or ever seen the liquid air compressor? The venturi check valve is available, but not the compressor , so far as i can tell.

Liquid air condensing ? mmmmm. Did they also want you to get the blinker fluid to fix the signal lights on the car?

Yes I have read that hundreds of times and it relates to the need for increasing human energy and mentions Linde's feedback process for producing liquid air. It was called Teslas fuelless generator, here is one link...http://home.earthlink.net/~drestinblack/generator.htm

It's actually kind of funny that nobody had a clue what Tesla was referring too. Linde's feedback loop was the start of Tesla's discrimination and individualization technology. It works like this, person A and person B want to talk privately so they use a feedback loop to individualize the transmission. That is a very high frequency feedback signal imbedded in the carrier signal which continually changes the carrier signal frequency so that the actual signal appears as either white noise or nothing at all. In affect the imbedded feedback loop modulates the signal in itself so that it can never be intercepted or deciphered and becomes individualized with respect to all other signals. Change imbedded within change, wheels within wheels is a recurring theme in much of Nikola Tesla's work... he was a very smart man.

Ahh! starting at high pressure, so you do not have to pull as much of a vacuum. That is the part I forgot. Thanks!  Also I meant the condenser, not the compressor, LOL But it's under another name, so that works.
