It's sliding off the roofs of parked cars as well as houses.
Whilst it could be a great invention to avoid the need for scraping ice off on winter mornings, I don't think any cars have CH.
I suspect there would be an outcry for pumping out fumes whilst parked.
But maybe that's something they could introduce for electric cars. I could see it working when they are charging.
Hmmm - do you think I should patent the idea?
The latest local weather report here is about 4" snow lying and more falling.
Google says it is currently zero degrees outside and my central heating agrees. My office thermometer said 16.0 degrees. Then the heating realised and came on to warm it up to a wapping 17.6.
