DIY waste cooking oil stove. No smoke no blower 

My own prototype of DIY used cooking oil stove. No blower no smoke.
Using recycled tin cans before I fabricate to GI pipes and adding oil reservoir... with air holes being experimented.
DIYers... bahala na kayo mag improve nyan. Hulaan na lang niyo holes sizing and spacing. :-)
Kaya pa niyo mapa blue flame yan.
