Norway's Oslo airport, in Gardermoen, opened in 1998, with a design capacity of 17 million passengers a year. Over 21 million passengers used the airport in 2011, leading to the construction of a larger terminal between 2013 and 2017 ().This increased the building floor area from 148 000 m 2 to 265 000 m 2 and raised passenger capacity to 28 million (Avinor, 2017).

Ceylan and his research group have run the numbers: Using 333 watts per square meter (about the energy used by three light bulbs) for seven hours, the operating cost is about 19 cents per square meter. Seven hours "is way more than enough to melt an inch of ice or snow," Ceylan said.
Ice-nine is described as a polymorph of water which instead of melting at 0 °C (32 °F), melts at 45.8 °C (114.4 °F). When ice-nine comes into contact with liquid water below 45.8 °C, it acts as a seed crystal (this is a strangelet) and causes the solidification of the entire body of water, which quickly crystallizes as more ice-nine.
The devices for an airport runway should be sturdier than I have otherwise described above. This system can obviously only work if the deep soil temperature is above 32°F or 0°C. In Arctic areas, some ThermoSiphoning would happen in winter, but possibly not enough to have the desired effect of melting snow and ice.

Title: Geothermal Heating of Runways Created Date: 4/17/2008 2:28:54 PM
Energy produced in this way can heat residential and office buildings, shopping complexes, eco-neighbourhoods, and public structures such as swimming pools while enhancing their energy mix. In winter, this energy may also be used to remove snow and ice from roads and airport runways, thereby reducing the need for salting operations. In summer,
They showed that a hot-pipe airport runway system is an efficient and sustainable method to melt snow and ice, has good practical applications, and can be used in central China and other countries.

(2) Wildlife remains that are found within 200 feet of a runway or an airside pavement area ...
located at sights compatible with novel off-grid power sources. To meet this goal, this project has the following research objectives: 1. Investigate characteristics of particular roads and sites that may make them attractive applications for this technology. 2. Investigate potential options for providing sustainable heating and associated ...
Black tarred runways, and concrete ones too, store heat and can melt the thin initial layers of snow. To clear the runway of snow will need a lot of power, enough to melt 1km of ice that is 20m wide per runway. That sort of heater is a little bit bigger than the kettle or toaster, and would probably bring down the local grid when it is turned on.

Roads are by far the most vulnerable, with cracks developing and water entering to rust the rebar and expand it up to 7-fold. It cracks from freeze/thaw cycles, vibration, heavy trucks, and salt to melt snow. Also vulnerable are bridges, airport runways, canals, parking lots / garages and sidewalks.
