I saw this in the paper today and thought it was cool (bad pun, I know). Instead of the typical propane or CNG powered machines, this one is electric. Less emissions from combustion, especially indoors, is always good. I am looking forward to seeing more of them in the future. Apparently Zamboni also has an electric model of some sort.
