Among the innovations: a cooling system that recycles heat from generators to power an absorption chiller which, in turn, sucks in fresh air through landscaped terraces.
This has been achieved with the aid of a cooling system run on superfluid helium, more than 2, 000 litres of which were loaded into the telescope at launch.
No word on when such a cooling system might actually appear in a retail product, but GE's engineers were recently in Japan meeting with Fujikura, maker of many OEM laptop cooling solutions.

That along with a high-efficiency cooling system resulted in a 34% energy savings compared to a typical building.
Rather than letting the heat escape, a cogeneration plant uses the excess energy to power a heating and cooling system.
The M11x also produced an incredible amount of heat, which was vented out of the back by a rather noisy cooling system.

Even before the reported explosion, officials were becoming increasingly worried about No. 2 reactor, due to a problem in the cooling system that hasn't occurred in the others.
The new Generation III reactors such as the AP1000 have a simplified "passive" cooling system where the water circulates by natural convection with no pumping required.
The Hailstorm II pairs an advanced liquid cooling system with a blustery current of cold air driven by three front intake fans and a large rear exhaust fan.

The analysis published Wednesday on the institute's website, 38 North, says that rebuilding the tower would take six months, but a March 27 photo shows building work may have started for an alternative cooling system that could take just weeks.
If the cooling system were to lose power during the initial decay period of 24 to 48 hours, a meltdown would likely follow.

The IAEA statement was released hours after Tepco temporarily shut down the cooling system in the second unit's spent fuel pool following the discovery of dead rodents near a transformer.
According to Bob Bauer, group vice president of Emerson Electric and head of its Liebert business, which makes cooling devices for data centers, the key to efficiency is focusing on the whole system rather than a single component.
At the new Intercontinental Hotels resort at Bora Bora, air conditioning for its 80 villas on a pristine lagoon comes from a system of pipes extending 1.5 miles offshore and 3, 000 feet deep, tapping the cooling power of 41-degree seawater.
If the pumps are knocked out in a Generation II reactor as they were at Fukushima Daiichi by the tsunami the water in the cooling system can overheat and evaporate.
