Concentrate sea water to brine for snow removal

Why not place sea water stils near oceans to concentrate and store brine in the summer and other sunny days for snow removal in the winter, see http://knowledgeaction.blogspot.com/2011/02/why-not-remove-snow-in-nyc-and-nj-using.html. The concentrated brine could be distributed more readily via tanker trucks. The stils should be in solid black to trap sunlight energy. Using conical covers would direct the steam for water recovery. The heat and pressure would kill any microorganisms and the steam could be used to generate electricity. Finally, the recovered water could be used to maintain greener parks and lawns.
