Fire Zamboni

Pay wall on this thing from SoCal, but it looks interesting:

“BurnBot is a huge, Zamboni-like vehicle that executes precisely controlled burns of flammable grass alongside buildings and roadways. It’s designed to create fire breaks — lines of charred land — that keep flames from spreading. When plants do grow back, instead of invasive, combustible grasses, it’s typically native, more fire-resistant vegetation.”
