Mmm, warm~

Hey I know a lot of people who aren't comfortable using matches or flame lighters. But like candles.

So look at this!

They've probably been around forever and I just noticed, but how neat. And a lot of them are usb rechargeable.

Also it's fun.

Study of the Physical Nature of the Electric Arc in Power Oil-Filled Transformers_Crimson Publishers

Study of the Physical Nature of the Electric Arc in Power Oil-Filled Transformers by Hruntovich NV* in Crimson Publishers: Peer Reviewed Material Science Journals 

It is known that during chromatographic control of combustible gases dissolved in oil, partial discharges and an electric arc are detected. Partial discharges with a low energy density correspond to the following ratios of combustible gases: C2H2/C2H4<0.1; CH4/H2<0.1; C2H4/C2H6<1. An electric arc occurs with the following ratios of combustible gases: C2H2/C2H4=0.1÷3; CH4/H2=0.1÷1; C2H4/C2H6>3.

The conditions for the formation of an electric arc in transformers, as well as the physical processes of the formation of partial discharges, are insufficiently studied. There are certain reasons for this. Firstly, not all experts consider partial discharges a dangerous defect. Secondly, in some regulatory documents it is recommended to measure partial discharges once every eight years. Well-known Russian experts in the field of technical diagnostic power transformers are put partial discharges on the eighth place in ranking controlled parameters of the diagnostic value. At the same time, chromatographic analysis of dissolved gases comes first. Undoubtedly, the chromatographic control of combustible gases in oil allows one to obtain integral information about local overheating and the presence of partial discharges. But if we add to this the speed of development of the defect and the magnitude of the damage, then partial discharges must come first place.

Protection Against Electric Arc Hazards

...  IEC 61482 1-2 standard has been published by IEC in order to determine the test methods of the materials and heat and flame resistant protective clothings to be used by workers who may expose to electric arc.
