There’s a lot of videos by different people about a mysterious hum that has appeared all over the world.
Except that the “mysterious hum” has been traced to a specific movie, and it’s the exact same sound effect from the exact same movie in all of the videos. So it’s not really a bunch of different people.
The candle thing could be similar.
If you want to heat a room (at least around here in Pennsylvania) you multiply the length, width, and height of the room to get its volume in cubic feet. Then you multiply that by a number between 3 and 10. 3 is for the best, modern, well insulated room out there and 10 is basically a barn. This will give you the BTUs you need to adequately heat that room.
So for a typical 10x10 room with an 8 foot ceiling, you’d need 10x10x8x6 = 4800 BTUs. So a “Mr. Heater Portable Buddy Propane Heater” (the first heater that showed up on my very quick google search - I otherwise haven’t even heard of this model before) would be able to heat this size room since it does up to 9,000 BTU.
Figure maybe 50 BTU for one of those little candles and you’ll need 96 candles to heat the room adequately. Now candles do vary quite a bit in their heat output, and larger candles could easily be double that, but anyone who tells you they can heat up an entire room with only 4 candles isn’t even in the right ballpark.
Adding pots and nuts and bolts and whatever other silliness you want to add doesn’t increase the heat any. All it does is change how quickly it goes from the flame to the air around it. An open flame like a candle is going to heat the air above it in a column very quickly, so most of the heat will rise towards the ceiling. Putting items above the candle’s flame to store the heat and release it more slowly out to the air will make the heat spread out more evenly into the room but it won’t change how much heat total you need to heat the room.
If you buy those little tea candles in bulk, you can get 100 of them for about 10 bucks. Walmart claims they will burn for about 4 to 5 hours. You need pretty close to the entire package every 5 hours or roughly 5 packs of those a day to heat your room. That’s about $50 per day on heat.
Now if you heat a much smaller room, say 7x7 or 6x8, maybe you can get by on half of that in candles, or only $25 per day.
I’m thinking electric heat is going to be a wee bit less expensive than that.
