I'll check when i get it in two weeks, but it doesn't look too heavy. The main frame could be plastic, instead of metal. There's not much high temp or pressure.An AA battery is few Wh and 23gram not much high temp or pressure, so very inefficient and very little power.

I got 70% alcohol. Need to further distill to 90% or burn from heated vapor. 70% might be safer to store than 90%.
