To answer the OP, I'm building one of these for summer. And to think I was going to go for a gas burner

Also, best comment from that page:
"... we are farmers in North Sulawesi, want to produce Bioethanol from Arenga Juice (Arenga Pinnata trees, palm family). Therefore we need alcohol stove, which, safe, cheap, eficient, durable, easy to make and has long burning time. After searching an learniing the nets for months, we decided to take your penny stove for our stove. We will sell the stove for household user, its price range usd 0.4-0.6/pcs. The stove will be sold to over 20.000 household in North Sulawesi. We will introduce Bioethanol as alternative fuel because North Sulawesi has over 2 mio Arenga trees and price for kerosene fuel will be higher and higher.
