So I've been working on a new kind of adjustable lab heater: electric alcohol burner!
It consists of a jar that contains fuel, a vaporiser, a wick and a combination tube.
The size of the flame is adjustable. I have a PSU that can supply 6 or 12 volts, and the POC, tubeless mock-up showed great results. Haven't yet
tested the final build, but [ChemPlayer TTS] it should work fine.
Images with the final build working will be up soon!

Haven't yet found fuel. The only alcohol i could find is concentrated isopropanol, technic alcohol at a paint supply shop(one liter costs 3 dollars).
But i do not want to use that, as it does not burn as clean and hot as ethanol and it also produces soot . So far i've used 70% ethanol rubbing
alcohol for my burners, but , because of the new pandemic, the city has been cleared of the rubbing alcohol. I'VE BEEN TO ALL SHOPS AND PHARMACIES IN
MY TOWN. And not a single soul buys the concentrated 90%+ ISOPROPYL. Little do they know that it's cheaper and better then rubbing alcohol. Chemistry
is essential, lol.
The 70% eth. also burns yellow because it is contaminated with dyes and stuff.

I managed to find a local place that sells 99.9% pure isopropyl alcohol (wow), for 2.44€ / liter.
Testing will begin shortly.anti - 17-3-2020 at 03:28
The flame is sooty because isopropanol is not the best. Flame height is almost 30cm.
Imagine how quick it could boil water!anti - 17-3-2020 at 03:33
Here is an image taken when it was still ramping up.
PS: I am very careful not to poison myself with CO.
