Really? I can't find any, just videos of people using them.

I already said I agree with you, I just prefer not having to see another Jack. If you think this is safe, fine, but there are people out there who will go out of their way to do dangerous things. The road to a dangerous place is occasionally more dangerous than the place itself.

Would someone mind going to this http://www.sciencemadness.org/talk/viewthread.php?tid=17770Page and telling me what it is about? I can't view it on my browser

Okay. Well, that got me nowhere. Any other ideas?

I thought you were trying to say something completely different. Who is gilded? I wasn't talking about the poem really, and I have heard other people talking about pine tables to. Oddly enough, it is always pine tables, and they don't phrase their posts as poems.

To me, the main problems with hydrogen powered cars are where to get the hydrogen and how to store it on the car. Solar power would work for getting the energy, but how do we store it in reasonable amounts? I was thinking the fuel tank could contain a block of lithium, and water could be stored elsewhere. The lithium and water could be used to make hydrogen, which could in turn be combusted the usual way. Lithium hydroxide would be produced as a useful byproduct, it could be sold to the battery industry, or back to the "lithium station" for a discount on your next purchase. The lithium station could take the hydroxide to an electrolysis plant, where the lithium would be regenerated with renewable energy, as well as some hydrogen and oxygen, which could be combusted to contribute to lithium production. The obvious challenges are where we would get all that lithium ore, and all that renewable energy. Sodium could potentially replace the lithium due to its much greater abundance on earth, but it is much more dangerous, and I think it has lower energy density. Has someone already thought of this? I would guess so, but maybe not. Lithium would also be readily available... Yay!

The reason isn't the acid, it's just I don't know how to pick which section I post in.:facepalms:We have LOTs of pine in my part of the USA. It really is such a lovely wood. It's just so hard to cut, without getting sap on everything...It's all pine TABLEs I hear about. Doesn't anyone know why people would want to destroy such a great choice of table?

Distilling hot, oxidizing acids is not my thing, and I don't like salts dissolved in my nitric. Oddly enough, it's easier to get nitric acid here than it is to get ammonium nitrate, just in low concentrations... Maybe I could find a few cold packs, but I don't think ours use AN. I have found it is cheaper and easier just to buy the stuff, who cares if the Feds start watching me, I don't do anything bad with it. :shifty eyes:

Wow, really? With a caesium on top? Even if I wanted to, I couldn't, and the only pics I got were of the glowing slag, it wouldn't satisfy your pyromania one bit.

Did I ever tell you guys about the guy from science madness who was melting HMTD in a glass test tube over a blowtorch with no safety equipment? Did I show you the pictures, and tell you WHERE he found out you could melt HMTD? Fine, don't delete it.

I'm still trying to find one of those big oil drums... It didn't work when I tried to scale it down a few months ago. I'm going to try going full scale, now that I have more than enough wood. Wow, that was really long! There were a few things I was unsure of while reading it. Through what opening does the blower blow? Could you try to give some more specific measurements? Maybe a diagram or two? Great post! For some reason this seems familiar to me.

I have some sulphuric acid, supposedly 98%, that I bought as drain cleaner. Anyways, it is really muddy brown / black in color, and I think it might have an inhibitor of some sort to reduce its corrosiveness. How would I go about filtering the acid? I was thinking of using some sort of sand filter, but I can't think of a way to contain the sand and allow the acid to go through. Would anyone here with some pure, technical grade acid mind using a pipette to put a single drop on a piece of standard printer and timing how long it takes to start charring? Tell me the results of course. It will help me decide if it has any inhibitor, if it does, I'll just throw the stuff away.

On someone's blog about h2o2 that I found randomly (sounds stupid, right? I did find it interesting though), I read that you can make exceptionally strong h2o2 with sodium percarbonate. Does anyone know how I could do this, and get a 30-40% concentration? Dilution is allowed, but I don't like the idea of messing with test grade+ HP more than I have to... Anything above 40 just frightens me, it's nasty stuff. Apparently the other product is sodium carbonate, could I remove that with a coffee filter, or would it (the sodium carbonate) dissolve in the solution? Please try to stay on topic, not that you wouldn't. This is meant to be a practical exercise, cost effectiveness is the overriding concern.

When I said "becomes a gas" I meant that the matter itself becomes a gas, not the NH4F in a gaseous state, that just sounds silly. Is it even possible for it to exist as a gas? I wouldn't think so, although i would love to be told otherwise. Sort of akin to candle wax becoming a gas when you burn it in air. Admittedly, that was a very ambiguous thing to say. I would like it if you would remove this post (this is an edit, I think I meant this whole thread, we haven't said anything of real use, no offense, just provided potentially dangerous information) so none of those anarchy cookbook fools googles triiodide, comes here, blows themselves up trying what John implied was possible, and completely ruins my reputation, as well as damage that of this site. As far as the anarchist fools go, thats just another one of natural selection's plots to better our gene pool. Triiodide is one of those trigger words that seems to attract every idiot in the country.

Wow, I really need to get a new source! And they say they are reliable...Hypervalent iodine, after someone says how to make this stuff, could you please delete this post? Don't want anyone getting hurt, and I don't know how.

I heard that in its molten state, it makes a good solvent for halogens and other elements. Is that not true? The similarity i was thinking of was its solvent properties. I did notice the bond distance as well. Wow, the classic undergrad's mistake of forgetting the extra H in the cation. :facepalms:You of course know the difference between sublimation and decomposition?

Well, I heard it is the only substance that can form a crystal structure with water, and that it has exceptional solvent properties in its liquid state. And it can become a gas at 100c, like water. Sounds similar enough to me.

JM, thank you. Right now I would guesstimate I have 4000 kg of nice, dense oak wood stockpiled in my backyard. Although people often think I am from the uk because I am "too eloquent to be one of those dumb Americans", I do in fact live in the USA, and I really don't think I'm all that eloquent. Anyways, I do have a garden, it is the pride of my neighbourhood, but how is that at all relevant? If I wanted to tinker, I am sure there would be better things to do with my time. I am trying to live a more symbiotic life, and to leave as small a footprint as possible. Sounds futile, I know, and that's because it is. But it makes me feel better about humanities hopeless situation. Just remember, my desired product is electricity. I want electricity, with as little effort as possible, and in reasonably large quantities, and for free. This must sound very demanding, but I am providing chemical energy, so why not? Seems like my best option is selling it as firewood.

Suppose I had a lot of limestone... Does anyone know how I would go about removing barium or strontium compounds from it? There should be some strontium and barium carbonate impurities in it, right?

I was thinking about ammonium fluoride recently, it's similarities to water. Anybody want to post some rumblings about it? What temperature does it decompose at, if it does? Could it exist as a liquid at atmospheric pressure? Would it make a good solvent for anything? How could I make it? Could I make it from ammonium chloride and something with fluorine? Any info appreciated, thanks!

Molten rocket fuel... 'Nuff said.

The challenge is: I have a coffe can and some pieces of wood, now how do I make charcoal with them?I really hate the method of heating the can in an external fire, the wood should be it's own fuel for pyrolysis. Please help?

I'm going to start out by saying that if you are a terrorist, you probably already know where to get it, and if you don't, a little effort should yield many ideas. Also, terrorists, I agree it was wrong to steal your land, but it wasn't me who did it, it was the American government. It probably won't stop you, but don't kill people who have done nothing to you in their lifetime... Would Allah really want that? Anyways, I'm going to see how many links I can get on this page. Mods THIS IS NOT FOR BOMB MAKING!!! I just want to make some copper nitrate, and test some silver, mkay? Anyways, if you know where to get it, post your link here! I'll start out with mine, it's pretty overpriced, but it's a start... http://unitednuclear...ucts_id=171Copy paste that into your browser.

I've heard ruthenium is great for heat retention... But it might be a little too cheap for your purpose... LOLRemember, after whatever you use is as hot as it will get, it essentially becomes a heat sink, wasting your fuel. I would reccomend you put it in later on in the burn. Porous things (aerogel) tend to be good for extended heat retention, more dense ones (osmium) for capacity of heat per volume. The trick is to find a balance between the two. Iron powder could work, but it can be flammable. Lead powder would probably be too toxic. I would reccomend a very course iron or copper powder, but plain quartzite sand would probably be the best in my opinion.
