If anybody reading this decides to give this a go, be very careful. The orange flame of the alcohol stove he demonstrates indicates that the alcohol is impure. If the purity is high enough, the flame is practically invisible in anything brighter than dim light. If you set the system on fire, you won't know it until it's too late.

Sidebar: It sucks that alcohol outdoor stoves are banned in some places. It's the only non-petroleum option for convenient outdoor cooking.
