Как отопить комнату одной свечей?

California inventor Doyle Doss suggested the original system — "candle heater". This weird-looking candle holder, says its Creator, can be invaluable during a power failure. Its height is about 23 and a width of about 18 cm And its appearance draws the attention of an inverted pot over a candle. In this pot (and it is in the "past life" flower pot was) and hidden the main highlight of the system. If you need point to heat a cold room in a private house or warm working at the Desk person come to the aid of hack American Doyle Doss, who offered the world an invention entitled "Trap heat".

Externally, it looks like an inverted flower pot over a candle. However, this pot is not simple, but composite, made of three pots of different diameters, nested into each other and put on a long metal bolt through the holes for the water. On the threaded bolt a few washers and nuts. The height of the "candlestick" is 23 inches and width 18 cm The principle of operation is to "trap" the heat from the candles. The fact that the burning candle gives a little light, but with a hot stream of combustion products takes much of its energy. Created by the same Doss maze-cap over the flame heat accumulates. The Central rod is heated, heats the ceramic, and then slowly warm air is passed across the surface of this kind of ceramic heater. By the way, instead of candles as you can use the heater and incandescent bulbs — in this case, instead of the candle is installed a lamp holder and connected to the network. The inventor emphasizes that one of such device in no way will save you in the winter when heating is switched off and power but, on the other hand, it is better than nothing at all.

Furthermore, although this simple construction is designed primarily for emergency situations (and not only at home but also outside it), candle mini radiator can slightly reduce the cost of space heating by adding a little warmth to the busy people the room, while the whole house "adjusted" the thermostat to a lower temperature. There are, however, still need to calculate the cost of one Joule in the candle.
The heater is also equipped with a fitted top stand that can hold a pot of soup. Before fresh "candle heater" will be able to properly heat a room, you need to wait until the residual moisture has evaporated from ceramic. It can take 3-4 hours, said Mr. Doss. But then the owner of the thing can fully enjoy the soft heat given by the heater for a long time. To keep the unused apparatus you need in a plastic bag so that moisture from the air is not absorbed. Doss writes that a wax candle weighing only 4.25 oz contains around 1 thousand British thermal units of energy. Translated into the usual size is about 120 grams and 1.1 megajoules. When you consider that this candle burns 20 hours or a little more, it turns out that the elaboration of the energy that it is 55 kilojoules per hour, which corresponds to a power of 15.3 watts. However, according to some estimates, the total "useful output" wax candle of this size will be higher. Closer to 3 megajoules. That will give the average power is approximately 42 watts. And if we take a closer "look" at a candle out of wax, then, perhaps, find in it more potential heat.

However, the exact number of the heat of combustion is not so important. Clearly, this candle holder cannot compete in the power of the household electric convectors and oil radiators at 0.5-2 kW. Until the outlet is current. On the other hand, when a current kilowatt heater you hardly will burn down the whole day long, if you do not want to splurge on electricity bills. A "candle heater" as already mentioned, on a single candle works more than 20 hours. The only important condition: it cannot be left unattended. Still open flame. The American innovator believes that such heaters should appeal not only to people sitting at home, but also those who are there rarely, preferring to travel away from the bustle of civilization. This heater should be a simple and cheap alternative to kerosene stoves and other kerosene stoves. And someday he may save the life of a man, say, car in snow trap in a Blizzard. Finally, the tiny Firefly is simply lovely. This invention should remind us all that once we (people) sat in caves at night around the fire and told each other stories," — says the inventor.
