Money or Currency? Wot Are You on About? Poverty or Wealth?
bee in her bonnet . . .
ponder upon the use of the words poverty, money, shopping, financial dire straits ... in the more Western lifestyle type of context.
but why are you paying for it all
simple candle lantern with flexy chimney below will bring temperatures up ...careful to add metallic surround for the chimney . . . the bigger the lantern the better ... that way more candles . . .
Unless you particularly like BONFIRES . . . special bonfires IN your house . . .
The same goes for electric lamps that should preferably be stuck down to whatever surface they are sitting on ... i put blue tack on their base so they don't fall over ... electric lamps are also a fire hazard if not placed carefully where they will not over heat near inflammable surfaces such as fabrics and wood, of which there are plenty in a dome ...
A shielded heater can be created putting metal shields around a shelf of lamps ... i use recycled oven shelves and panelling found thrown out in the street .. . and rarely use lamps more than 40 watts
So basically be VERY careful to avoid putting too hot a lightbulb too close to wood or fabrics, or anywhere where something inflamable can over heat and catch fires.
If one goes for the candle lantern option, then in a super insulated small space you need to evacuate the candle vapour with a chimney.
I didn't need it as this structure is not air tight and just opening the door during the day as you go in and out gives the air circulation you need.
