Flamethrower

So this post is either getting shot down immediately, or I’ll receive some good feedback from some likeminded people, but I’m gonna try. So recently I tried to start a bonfire in the cold closer to nighttime, and my propane flamethrower did a horrible job because I had to keep the flame on this fire for a very long time, which sucked. Of course, there are probably easier ways of starting said fire than I want to try, but that’s boring. My idea is creating a liquid flamethrower, so that the flame burns on the wood for an extended period of time as opposed to having to hold a flame to the wood for a long time at once. Before you say something, yes liquid propelled flamethrowers are legal in my state to an extent. Anyways, I understand the basic dangers and solutions to erasing those dangers for the most part. I think the most basic design people do is a tank, pressurized with co2, with a gas/diesel mix inside, ignited by a wick at the end of a hose/barrel. If anyone can point me in a direction of how to make this design for relatively cheap, I would very much appreciate that. And if there are any other possibly simpler or cheaper ways of doing this somewhat safely, please let me know what you’re thinking.
