I wonder if the piezo will ignite alcohol vapors...anyone tried it?

Tesla's original idea was to supply electricity to homes via a large coil. Yes, the high voltage through the air

It works for butane.

You might find this interesting too. This guy built his own wind tunnel. He wanted to test something called a KF airfoil. What's interesting for us is the way KF causes a turbulent airflow with just a simple stepped wing. Turn that into a stoves outside wall and all you have to do is make the bottom...

This is way too technical (see below quote) but studies have shown that dimpled surfaces work. All of these stove building trials we diy have to follow the same rules these guys did for turbines. Things like Reynolds numbers (low reynolds numbers in our case) are always mentioned in the RC airplane ...

Most of the answers will probably come from zelph. The only thing I ever found that interested me was the idea of dimples in the windscreen. The idea being turbulent air next to the pot allowing more heat transfer. Beyond that you get into rocket stove territory and a lot more weight to gain efficie...

Zelph's wife and his wife could probably share some interesting stories

The only intake and exhaust for wood fires that I have seen had to do with smoker designs. More like an oven than an open burner that has access to plenty of air.

I'm not going to try this but it did make me think about stove ignition ideas.

I will be making my coffee this way with both of my zelph wood stoves 8-) gGP_nY3kMGA It's still not too late to review this method so you've got it right before heading out for a weeks worth of trail time. I'll be heading out week after next. :D I'm an expert now. Cowboy coffee really is the best ...

RG, What's the Uke count up to now? All this time passed, you must have hundreds made.

Nice to see the basket idea working. I was wondering how it was going. I get the same kind of mineral buildup on my furnace humidifier using city water. I have to soak the innards in CLR every season to get it all off. The poor little motor that turns the drum is about burned out from all the extra ...
