can’t one make a fire with any level of wattage… i believe even a copper tread of a treaded wire should be able to start a fire of an AA (1 watt) battery, and human body puts out something like 68watts of heat energy… sure we can make fire but from raw heat out put it’s pretty difficult.
sure electricity does compact it into a small area… there are many safety concerns to be aware off when dealing with electricity, like don’t pack it in tinder or keep anything flammable near by because something will eventually start a fire…
i’m more worried about the devices that casually trust not to start a fire, than my macgyvered which i know the exact sketchyishness of.
besides if people are going to burn down there house, the odds are really past now… xmas is the time for that… with all the dried pine and live candles left unattended…
electricity is to be respected, all the way from 48 volts and up, it is much like fire… it will bite or eat you in many different devilish ways.
a good example could be how professional restoration workers accidentally burned down the Notre Dame, or how for decades aluminum wires were used in homes and caravans, making incredible fire hazards simply because people started using a new material they wasn’t familiar enough with for that particular usage.
most things when not understood can be very dangerous, the most dangerous part being the things one doesn’t consider.
The aluminum thing was actually pretty interesting, due to aluminums thermal expansion being very different from many other metals used for electrical connections, the wires will literally work themselves loose over time, thus begin to cause arcing, which is one of the most common ways that cause fire, especially today since most electrical stuff is in thermal set plastics, meaning they won’t burn.
another thing most people doesn’t realize about aluminum is just how highly explosive it actually is, granted it’s very difficult to make aluminum react in that way due to it’s amazing oxide layer, but doesn’t mean it’s a great plan for people to start pumping power through it lol…
but i digress…
it’s really easy to create disasters, the really tricky part is avoiding them, 100watts can certainly get some work done, but the real fire hazard i would argue is the surroundings, not a hot wire.
so i would say… always keep in mind that electronics in most cases can burn and should never be put in locations where they with easy can turn the rest of the house on fire… infact it’s a pretty good idea not to build houses so they can burn… it’s just a bad plan to live in a fire trap.
i know it’s been a while since a house fire took out an entire city, but it was why we stopped building like that…
