Yea, preheat the cat. We can put heat tracer on lines to spigots in our homes to keep them from bursting in the winter but automotive companies can’t put something similar on a catalytic converter to get it past it’s activation energy?

Please…

This article is not about engines idling. it is about specialized fuel-burning heaters sold in Nordic countries. They do not have cats.

Car companies already know how to get cats to heat up quickly. They use precats. Using electricity to heat the cat would seem like a bad idea when it's really cold, as the battery is already heavily loaded and operating at reduced capacity. Some people actually put heat blankets (mats) on their battery to warm it to get around the reduced capacity thing.
