That does explain why it seemed like the fan stopped working when i placed it in the cone... , gonna try something else. I saw a broken hot brush somewhere...

Fans are know for generating high flowrates (cubic feet per minute). While flowrates are high, the flowrate drops off very quickly with obstructions like bends and turns. A classic example is the fan in a PC. Outside of the box, the fan pumps a lot of air. Once mounted the actual flowrate drops lik...

I am assuming that the pump runs off of a DC motor. That being the case, the amps required are directly proportional to the load or torque needed to drive the pump. To extend the battery life, the load requirements need to be managed. This includeds; Limiting the air line length and not going with ...

I'm in need of mass storage for at least a 3 day outing without having to recharge or carry additional batteries. That was my initial line of thinking. Good to see you seudo_411 :D I may consider using the blower that I had on the "Martha Stewart" wood burning stove. Daren, using the smaller batter...

watch batteries are also 1.5 volt. i made an LED lantern that uses two little button batteries. connected in series, you get 3 volts.

The reason I use AA batteries, is because they are rechargeable. I'm currently doing the fan blades...

Zelph: I have been looking at this new idea of your and I made a small motor/battery pack combo, basically a 3volt dc motor powered by two AA's. with a remote micro switch, what i want to do is to make a zip stove, for alcohol. pics will follow later on, need to get my phone cable...

I would like to make a somewhat precise, circular hole about 1 to 1-1/4 inch in diameter through a cottle bottom. Not being an expert in fabrication and only possessing a drill, could someone recommend a specific type of bit and/or procedure to do this? I don't want to do any jig cutting and filing...

Zelph I know how you can get rid of the problem on your TI cup, make a thermite stove, then you'll have a bottomless cup.... :lol: But you could fill the cup with damp sand, and place a wood cutout on top, and compress it with an arbor press, should help a lil bit. As for heating the cup, be careful...

Boric acid makes green flames, maybe some thin gauge wire will help make the flame visible. Magnesium burns bright white, and super hot if you can get it to burn some how...

seudo_411 , you make some good points to consider. Because the matter in question is whether or not a heat reflector aids combustion. what your test will show is that siphoning heat from the stove body and its immediate environment will adversely affect combustion, by inhibiting the vaporization of...
