Molten-salt reactors are a type of nuclear reactor that uses molten salt(s) as a coolant or as a solvent in which the fissile material is dissolved. Experimental salts using lithium can be formed that have a melting point of 116 °C while still having a heat capacity of 1.54 J/(g·K). [4]
The torch melts the coating material and the top layer of the component material; fusing them together. Due to the high heat of spray and fuse, some heat distortion may occur, and care must be taken to determine if a component is a good candidate. These high temperatures are akin to those used in welding.
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.

The more ice melt your salt spreader can hold, the more ground you can cover before you need to stop for a refill. As a rule of thumb, you’ll need to spread about 3 pounds of salt for every ...
After shoveling the driveway, insulating your windows, and clearing icicles from your roofline, the last thing you want to do is clean pesky salt stains off the floors in your entryway.
Around the melting pit is a thin jacket full of warm water, heated by a powerful burner. The gases from the burner are bubbled through the water, causing some of the heated water to spill over into the melting pit, melting the snow instantly. The meltwater is discharged into the storm drains. [47]
