When it comes to cooling systems for a data center, one of the most traditional approaches has been hot-air and cold-air aisle containment. Both dependability and efficiency can be increased by using the method of containment to eliminate hot spots and prevent IT machines from overheating. Separating the cold air from the warm air is the primary objective when it comes to containment, achieved through modifications to the air flow such as fans, vents or air conditioners. To keep the hot-air and cold-air aisles apart, containment strategies require that IT racks be arranged with the front of the racks facing each other, creating alternating aisles of cool and warm air.
With nuclear power being talked about more these days as an alternative energy source over concerns for CO2 emissions, let’s familiarize ourselves a bit better with it.
A nuclear power plant is a power station which uses the heat from a nuclear reactor to generate steam which is harnessed through the use of a steam turbine to produce electricity. The first operational nuclear power station was erected in Tennessee in 1948 and was modestly used to power a light bulb. By the mid-1950s the model was being set up to operate an entire power grid, first tested in Obninsk, Russia in 1954. By the end of the 1950s nuclear power plants were appearing around the globe, such as that in Shippingport, England and Cedar Hall, United States.
It is hard to imagine an urban city of the future that does not employ LED lighting. Larger cities have not moved as quickly to utilize the technology; it is the smaller, developing cities like Detroit, Oakland and Pittsburgh that are leading the way. Earlier this week, Detroit was commended by Energy Secretary Ernest Moniz for its choice to utilize LED lighting in the coming years. LED lights are a godsend to cities like Detroit that are looking to rebuild and thinking about long-term strategies to that end. Cities like Detroit are short on cash, and some might be hesitant to invest in the high initial cost of LEDs; but savings over the long run make it a smarter fiscal decision.
