arent you guys worried about this stuff getting into the dirt around your property, especially if you are doing off grid living and probably have a garden near by.. or kids
i would not want antifreeze in my tomatoes, it just seems like a bad idea. ethylene gylcol is also pretty toxic i think, and you can possibly effect animals and useful farm insects like bees.
is it even legal to pour this stuff on a solar panel. rain-x is nice for a windshield but i dunno if spilling gallons of it on your roof is a good idea.
plus, applying this stuff is kinda dangerous, if you want to get a ladder while there is snow outside or whatever. so is cleaning it in the winter because its a weird center of mass on a long pole and you can easily slip outside of your house. these seem contrary to safe living off the grid where you are likely far away from a hospital. not sure what twenty years of using weird pole brooms does to your back as well. might be hard to figure out how to do it ergonomically.
an interesting machine related to back health and cleaning
i wonder what kind of sensor could be used to detect snow. maybe a automotive reflection sensor combined with a mass sensor that basically detects glass obstruction and snow mass.. but i dunno how to isolate that from the wind.
