The helium, which by then will have risen to about minus 15C, is pushed through a liquid nitrogen "boiler" to bring it back down to its run temperature, before looping back into the pre-cooler.

Some of the suggestions include using molten lead as the coolant for the system, but the reactor would run at a temperature above 700 degrees C. when the material becomes corrosive.

But if they can then get it to work in p. furiosus, they could run the whole system at high temperature, high enough to allow the biofuels produced to be distilled without having to build a separate distilling apparatus.

But because factories were allowed to -- allowing warm water to run back into the river, the temperature was becoming too high for the salmon to survive.

As a consequence data centers are using an increasingly large amount of power both to run equipment and to keep the operating temperature of that equipment at appropriate levels (this has led to building many newer data centers next to hydro-electric and other inexpensive power sources as well as in colder climates).

One of the strange things we learned during our hands-on was that SLI is complicated by NVIDIA's GPU Boost technology, which causes individual cards in the same chassis to run at different clock speeds depending on their load and temperature.
