Issue 256 Snow plow alternative January 23, 2014

Well it is winter here in New York (where I live) and the snow plows are pushing that snow around and dumping salt. But there is a problem, and this idea may just solve it.

Problem: Snow plows in New York dump ice melt (typically salt) onto roads to help melt the ice. However, that same salt ends up in the soil, our sewers, and even our oceans. As such, it harms the environment. Also, when the plow comes through, it simply pushes the snow aside and creates piles of mini icebergs which in some cases bury cars in more snow. Is there a way to solve these problems during the winter time?

The idea: Well, my idea is to instead harvest the snow. When water freezes it expands, so the plow instead of pushing the snow aside and dropping salt will harvest the snow and drop it into a tank in the vehicles. This tank will then proceed to melt the snow (which reduces its volume). At this point the crew of the vehicle has two options. One is to super heat the water inside the vehicle to spray on the pavement to melt the snow they did not collect which in turn would instantly evaporate the snow itself. In this case the sprayer will be just behind the collection plow and the superheated water vapors from the melting snow can then be recollected via a vacuum in the middle and aft of the vehicles. The other option is to take the tank of now heated water, pull up to a sewer drain, and then pump the heated water directly into the sewer. This will allow the drains to be cleared of any frozen material, clean out the sewer system and at the same time prevent the pipes in the sewer from freezing. All this combined would solve both issues all at once without the use of salt or other chemicals and without dumping snow all over the place creating large piles that take forever to melt.

Is it feasible?: Yes it is feasible, because we have the same kind of systems used for agricultural farm work. The only difference is the tank on the back which would act as a kind of oven for the melting snow so that it becomes super heated.

Problem: The only way to make the system work properly is to ensure the snow that becomes the water pumped out is super heated. If the water being pumped out does not evaporate the other snow completely, it will simply freeze. Also, a fuel source for the vehicle will be needed as that is a lot of weight to carry around. Thus, a hydrogen powered engine that performs electrolysis to harvest fuel from the heated snow it takes in would be the best option in this instance. As such, once the initial fuel (water) is added, the truck can go on perpetually simply by melting more snow.

Conclusion: This is another one of my ideas that I hope inspire someone to solve the aforementioned problems. Winter in the United States (especially in northern States like New York) can be very sever and even deadly. So solving the environmental problem and the issue of these man made ice bergs would do much to help clear the streets making it safe for drivers during winter.
