They are not good.
Maybe if places actually used potato dough it would better.
I’ve seen either pizza dough, gravy, cheese curds + optional meat(bacon or donair usually) or what’s essentially a poutine dumped onto pizza dough, so fries, curds and gravy.
I’ve seen people eat them. That’s the best review I can give.
Take a look at cement board and the codes for your area for a wood stove.
There’s certain gap requirements for heat etc but you could rig up something fairly simply whether a box or more open enclosure.
There are also fire extinguishers that are activated by heat and sit above a potential fire source. People use them in 3D printer enclosures fairly often. Batteries burn for a long long time depending on how charged they are so it would have limited effectiveness.
This could actually be a really interesting and useful product idea. Maybe a kit with GFCI outlet, surge protector bar with fused outlets, huge spacing between outlets to allow for large plugs, metal/cement board case, wire shelving, ventilation fans to keep batteries cool but have louvre shut to cut oxygen for fires. Hmmm I want this for my garage.
