Using 5¬∞C air to cool 70-80¬∞C chips was only logical if energy consumption and environmental consequences were ignored. Now that they are important, sequestration of computers to put them underground is similar to the illogical idea of hiding CO2 underground for future generations to deal with. The best solution is to go directly to cooling the chips with water or an environmentally friendly, dielectric refrigerant (allowing it to partially evaporate) to take away the heat at a fluid temperature of 50-60¬∞C that can be cooled directly by outside air, ground water, etc. Both approaches can dissipate the heat directly into the enviroment without need of a refrigeration system, or better yet the heat can be recovered for other uses (building utilities, district heating, etc.). Such an operation primarily only consumes pumping power, much less than that of a compressor of a refrigeration system. This is what GREEN COMPUTING means in general terms since the energy conumption (and CO2 footprint) per computation are reduced. INVISIBLE COMPUTING is a short-term underground, off-shore or remote location solution to the illogical use of air to cool computer chips. Nowadays, the green technology roadmap should not be based on "thin air". Even illogial technology has sometimes “logical” solutions.

Data Center locations with high power availability and energy efficencies will be very attractive for hosting computer systems. <br /><br /> Many companies are taking advantage of underground data centers to save on cooling costs. Since cooling servers takes 40%-50% of all data center usage, cutting by 30% is a huge savings. Sun Microsystems and Marriott are two companies that have recently moved their data centers underground. <br /><br /> My prediction is that companies will start looking at and moving data center services to areas with low-cost power and locations with an energy savings advantage.
