The only effective way to cool 52 KW racks is with a cooler in front of the rack - This unit requires a 15 ton capacity coil, but can be lined up side by side. Each rack stays cool.
Smaller units work the same way -For example- put a 4 ton coil in front of a rack of 40 opterons - cold air in the front regardless of the room temperature. 80 opterons / 8 ton coil The computers provide the fan - no crac unit needed -
Size the cooler for the rack, hook it to the cold water, - repeat as needed.
This adds 8 to 14 inches to rack depth - and has no hot spots.

Bigger computers - bigger coil - one rack at a time I can cool any installation you have !
I am going to roll out the first installation this summer.
From my patent application -
Background of the Invention [003]Computers are sometimes cooled by cooling the air in the room in which the computers are located. A typical cooling system cools air and moves it through the room with the devices in the room that need to be cooled. When air is used as the cooling medium, variations in airflow occur, particularly when the heat density rises in a region of the equipment room, or when the absolute heat load approaches the maximum load that the air can handle. In an effort to solve resulting problems, systems have been made in which the devices that heat up are placed inside of a closure and the air inside the enclosure is cooled. These systems have been found to be inadequate when the heat density is above about 8 Kw. None of the existing systems are able to effectively operate in an environment in which the heat density is between about 20 to about 40 Kw. Yet, manufacturers are starting to make computer equipment in which that much power exists in the system. Currently, when the heat density is high, the systems are provided with greater floor space and larger air handlers and chillers. This approach has led to the creation of "hot spots" in the equipment. The known systems fail when the power level raises to about 400 watts per square foot, or when the cooling requirements vary substantially in a given space. [004]When airflow in a single rack approaches about 3,000 cubic feet per minute, and an aisle of about 20 racks approaches 52,000 cubic feet per minute, the conventional systems cannot handle the airflow in a computer room of conventional size. The use of larger rooms is expensive and they are still subject to the airflow problems that are created. These problems include the creation of "hot spots" which are regions in the room that are not sufficiently cooled and in which the devices that generate the heat are adversely affected by the heat. There is a need for a cooling system that avoids the problems of the prior art systems and which eliminates the "hot spots". A principal object of the present invention is to fulfill this need.
ABSTRACT
A device that in use generates heat is positioned within an enclosed space that includes an ambient air inlet, an outlet and an air mover for moving ambient air through the space from the ambient air inlet to the outlet. A cooler comprising coils and passage ways defined by and between the coils to which ambient air moves from the inlet of the cooler to the outlet of the cooler. Position in the cooler with its outlet in register with the ambient air inlet for the enclosed space. Using the cooler to cool the ambient air that is immediately forwardly of the ambient air inlet for the enclosed space. Using an air mover in the enclosed space for moving the cooled ambient air into the ambient air inlet, through the enclosed space, and out from the outlet of the enclosed space.
I bought a HP 4Si duplex printer used for $30, and a bunch of toners at $10 each. I expect to be printing postscript friendly for several years before I need to worry about printing again.
The local government and educational units have surplus sales that make it easy to live cheaply a cycle or two behind the "latest" thing.

The small doses used by homeopaths only have an effect when a person has a hypersensitivity to the small doses given. If the wrong medicine is given to a person, nothing happens. If the correct medicine is given, the medicine acts as a catalyst to the person's defenses. In any case, homeopathic medicines do not have side effects.

As for homeopathy in the U.S., it was also very popular here. At the turn of the century, 15% of physicians were homeopathic physicians. The A.M.A. was seriously threatened clinically, philosophically, and economically by homeopaths. As distinct from other unorthodox practitioners, homeopaths graduated from respected medical schools. The A.M.A. was so threatened by homeopathy that from 1860 to the early 1900s a conventional physician would lose their membership in the A.M.A if they simply consulted with a homeopath. The A.M.A. also applied pressure on various funding sources so that the homeopathic schools had difficulty staying alive. Despite the strong pressure from A.M.A. and the drug companies, homeopathy has survived and has flourished throughout the world.
I was contracting there and saw it running

This does not solve the Problem-- The ability to write a replacement for { word,excel,powerpoint,etc} depends on the calls between each app and the os, each other, and the ability to read-write documents that users of MS products can use "transparently". In short the system and program calls and file code/decode must be Public Info. This allows the competition on value/features/price to function outside the limits of the monopolistic effects. I see a simple test. Does programers B have the info needed to write a replacement for an app. If not, a fine structure that supports the finders and the govt oversight costs ( One Million for finding an undocumented call from Word to the Os, for the finder and One Million to the Govt for enforcement expenses ). The same for each interface, file structure, calls to other programs. Microsoft CAN provide that info, and the net community can write replacements for the things we need. Those who want to have the security blanket of the "BrandName" can still buy it.
who should expect a lawyer soon. We must, however, address the larger issue of the legal system we are building. The principle of first use is based on "adversarial" (sp) use of lawyers. The lawyers like to get paid to argue for money, and it serves many cases well. However-- in issues important to society in general, we need to establish a way to discourage false or destructive use of the legal system, and not depend on the little guy to fight the battle alone. When it takes more money than you have, or can afford without affecting your family, defending the "Right thing" is not reasonable. ?? Suggestions ??

Same idea as having all user data under one branch so we can back it all up.

Linspire works very well for the "windows style" user if the person setting up makes the user accounts,
and does not let them just run as root.
ClicknRun is very effective, and I have had no trouble with the one computer I have running it
for general house use.

Irrigation canals in Brazil used a venitian blind loop for local power. 20 odd years ago at least.
like little wings on a pulley set up
vertically in the canal.
I bought a HP 4Si duplex printer used for $30, and
a bunch of toners at $10 each. I expect to be

The local government and educational units
have surplus sales that make it easy to live
cheaply a cycle or two behind the "latest" thing.
The important part is the UL listing for
the PDU, preferably mounted in your rack.
That makes it a legal install in all the
US electrical codes that I have heard of,
and a simple "buy one, install it" solution.
