Who uses snow melting machines?
Many apartment and office buildings with exterior ramps leading to underground parking use heat in the ramps to prevent them from getting slippery. Shopping centers with multi-level parking might be interested if your machine is cost-competitive with the cost of clearing and hauling the snow. I would think, however, that any snow-melting process will use much more energy than a loader and truck to merely haul the snow. For that reason alone, your machine is likely to be of interest only to those property managers who have other concerns such as the need for immediate or continuous snow removal.
