Recently I bought a homemade Mare questions I wanted to ask about the appropriate types to use, anyone have any suggestions for types of alcohol does it matter what the duration of the burn of alcohol?
Thanks for the answers.

The most desirable alcohol can achieve 97% agencies to supply clinics dental (dental Depot "for example) the price is around $ 30 per liter.
Minimum recommended is denatured alcohol throughout Israel and have toprmartim.

White or white alcohol smirt building materials store in containers of one liter.
Also called denatured alcohol then add him bluish color.

Ma, mpogel. they put him what kind of shit, keep us demands to open Irish vodka at the problem using it on very chalia soot.

I, as well as 99% of the American market, using methanol.
Relatively inexpensive and used me for other purposes within the vehicle.
No soot, no smells and works great.

The only downside is its high toxicity. Should avoid contact with the skin and most important be careful not to drink it.

Where do you buy methanol? How much does it cost?
I'm looking at gas stations and never seen.
I realize that using an us-Paris is methanol.

Its members,

There are other drawbacks to mtnol:

1) low energy concentration than atnol 16 MJ/L, 20 authenticated

2) his very high toxicity (so much so that to kill a person enough a few millilitres). I have a house clean and far from tanol feat if hand stickers "red poison".

3) a tanol responds to aluminum, so if you're going to use aluminum choalia (and most likely a neighbor), you shorten the lifespan.

With all it has mtnol-pormaldgid response and factoring of Platinum catalysts and create heat eventually. Without get too in depth you can do when you don't have to turn on oalia She just work alone. This is a great project for those interested in chemistry, but not practical because of the disadvantages mentioned above.

So what better place if indeed she chalia aluminum?
I am looking for a material that will burn as much as less to carry. Better be cheap too. Is there anything that meets those needs.

Agree with what you say, but I want to point out some facts:

1. in response to aluminum was convinced that cause corrosion like methanol whiskey once in aluminum ihasnti of MSR. For a year, sitting in methanol has no change. (Methanol levels going up and down depending on usage, but no significant reaction)
2. I use with the deal reduces XL, aluminium, for over two years. At least once a week. Problem with methanol.
3. lower energy concentration leads to carry more material during an excursion, but usually iistchm on 100 g for a three-day trip. (Besides, you probably already take little see p98) in addition, every few years can make a new one:)

I was very careful in storing methanol at home, or more. At the very least there sitting in bottles instead of access to children.

Can I have some more details on the chemical chalia you speak of? Intriguing:)

I purchase methanol chemicals warehouse in Holon. Price is 8 per liter in the purchase of 18 liters.
There are also chemicals factory in Haifa that cost him cheaper but has a shipping cost of $ 50 it might be relevant to the purchase of 36 liters.
In my usage, it takes six months to a year old to finish this tank (depending on the rate of maila in).

Methanol: its LD50 is something like half a gram to kilo body (ingestion).

To kill a person weighing 70 kg has 35 g methanol i.e. fifty ?cole militaire Metro, or quarter Cup.

Ethanol's energy content per unit of weight, about 30% higher than that of methanol.

Methanol can be used as antipriis as any other liquid soluble in water, but that the vehicle is antipriis ethylene glycol.

I didn't quite understand the methanol rather energetically on alcohol?

Energy-wise ethanol is much better for our needs. In terms of price, a little less;-)

Incla if going by the book. " But who wants to take a chance:
Methanol has a high toxicity in humans. If as little as 10 mL of pure methanol is when ingested, for example, it can break down into formic acid, which can cause permanent blindness by destruction of the optic nerve, and is potentially fatal 30 mL

Refresh to choalia. It is better to see that tell you about how it's possible, but in a few words I write here. Echoes of catalyst in the presence of oxygen and tanol (black Platinum) are the pormaldgid, and heat. You can see an example here:

If you notice they're warmed Platinum before. The problem is that the heat is turned on, tanol enough surface area for a Platinum must be very large in relation to its mass (to reduce thermal mass). So what do the products that use this response (such as lighters:
it's not these black Platinum Platinum (Platinum Black). Platinum Platinum black is very small grains so that when a surface coated with these grains out huge surface area in relation to mass. The cost of this material is very high, it is clear that Platinum costs some $ 40 per gram. Saw sold one gram of Platinum black on $ 200!!! But can be produced in the laboratory (but possible). Create a separate story Platinum black if you want detail.

In fact the effect came out like a light. This part of the catalyst may be placed on the pot. So when you put a pot on top of this, light oalia

I'm sure there's a reaction that creates heat, but no flame. If it saves me a light day in SA, then the investment does not excuse.

Thanks for the Info:-)

You can also do heat without a flame if it matters to you. Warmers that have used the response if a platinum catalyst in the form of a network. Interesting?

We pull the thread in a different direction than he bargained for. If not, I'd like to open a new thread.

Whether the catalyst is "infinite" or mtavla?
Have successfully created during boiling?

Could be an interesting solution to an old problem where fire:-) And frankly, even intriguing.

Agree with you about a new thread.

The catalyst, but obviously something infinite. About boiling I'm not sure how long it takes. Not appreciated such an experiment. I worked on a specific project with Dan from ZelphStoves. He made a prototype:

It seems to me exactly what you're looking for.

These projects are just curious. But how useful I don't know.

I wouldn't bother me particularly, quite interesting discussion.

What I wanted to know I got enough so enjoy!!

Of course, the definition of infinite terms is something that lasts a couple years without ב"מילוי" (except, of course, methanol)
I'm not really looking for anything, but it could be very interesting to see it works:) and making coffee.
Do you still have contact with? You can ask him if he couldn't get anything.

Like me the curiosity. Do try to produce something like this? Low chance.

I can direct you, but business is not cheap at all:(
Mince one of Platinum Thermocouple Wire costs around $ 2-3. Need some network "creation and experimentation. I look for some left of previous experiments, can send you. About creating Pt Black, have a considerable amount of Platinum (preferably a few individual grams at $):).

I talk to Dan about his choalia. Exactly one week before I bought him when his new oalia StarlyteXL experiment. Write a review on it here.
