An Aeroflot Airbus A330 being de-iced at Sheremetyevo International Airport Econ Salt Spreader. De-icing is the process of removing snow, ice or frost from a surface. Anti-icing is the application of chemicals that not only de-ice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.
Temperature distribution in a thermal bridge This thermal image shows a thermal bridging of a high-rise building (Aqua in Chicago). A thermal bridge, also called a cold bridge, heat bridge, or thermal bypass, is an area or component of an object which has higher thermal conductivity than the surrounding materials, [1] creating a path of least resistance for heat transfer.

Failure to clear all the snow and ice from a vehicle causes hazards by impairing the driver's visibility, and ice from the roofs of driven vehicles can cause crashes. [11] In some jurisdictions, motorists who fail to clear snow from their vehicle entirely may be fined. [12] Others may be more thorough in this process.
As a vehicle travels on the road, a dynamic loading regime is exerted onto the ice cover. [1] [4] Below a specific speed, referred to as critical, the ice cover beneath the vehicle will assume the shape of a bowl moving with the vehicle, pushing away the water around it, as the keel of a boat does.

A heated sidewalk in Holland, Michigan Installation of a geothermal snowmelt system on a street in Reykjavík, Iceland.. A snowmelt system prevents the build-up of snow and ice on cycleways, walkways, patios and roadways, or more economically, only a portion of the area such as a pair of 2-foot (0.61 m)-wide tire tracks on a driveway or a 3-foot (0.91 m) center portion of a sidewalk, etc.
It is a result of snow, ice, water, loose material and the texture of the road surface on the traction produced by the wheels of a vehicle. [ 1 ] Road slipperiness can be measured either in terms of the friction between a freely-spinning wheel and the ground, or the braking distance of a braking vehicle, and is related to the coefficient of ...
UK researchers at Loughborough University and the University of Sussex concluded that waste heat from light-duty vehicle engines in a steam power cycle could deliver fuel economy advantages of 6.3% – 31.7%, depending upon drive cycle, and that high efficiencies can be achieved at practical operating pressures.
The heat conduction can be minimized by any of the following: reducing the cross sectional area of the bridges, increasing the bridge length, or decreasing the number of thermal bridges. One method of reducing thermal bridge effects is the installation of an insulation board (e.g. foam board EPS XPS, wood fibre board, etc.) over the exterior ...
