It's probably full of a lot of trash and impurities

I'm sorry are we talking about the Hudson or the snow?

But sure, I to don't want to keep using rivers as a toilet. I'm just not sure the energy costs are better since that is also a pollutant and this injects another machine as a thing that needs parts, grease, salt and a lot of generated heat, as well as a bottleneck on processing speed.

This feels more like a good salesman was involved than a practical decision.
