i read the book the giza powerplant [19 Apr 2006|08:59pm]

hiiski
And now i have an idea id like to try
tell me the flaws of logic if you see any
Take a pyramid shaped area and put it on the ground on sand it will then pick up on the earths natural resonant freq.
it will make the entire pyramid vibrate the earths tone
if you applied that tone to a helmhortz resonator to alter the tone and had that in a chamber directed towards a sonoluminescent medium

It should illuminate correct?

Today I sat around and thought up two experiments to try.
1. One was the initial exploration of casting Silicon. I tried a simple drop casting which met with better results than I had anticipated initially. I thought the crystal would fly apart when it was first heated, but the fact that Si is a semiconductor, and didnt accept the plasma right away helped. I had to bridge the arc onto a piece of copper and heat the Si with the imposed plasma heat. Once a pool formed the plasma went to the Si, as it should. The rest was easy. I lost 0.0082 grams in the melt, so it was good in that respect.

The issue was that Si acts more like molten glass when its molten. I didnt anticipate this. So the surface tension was really high, and didnt want to drop cast. I think if I used a vacuum assist to drop it into the mold, it would work.

I will try a few other experiments later. I might even add a like metal to help reduce brittle issues. (Like Ge haha).


2. I tried to weld Copper to Aluminum. Crazy? yes. But you have to go and look what weld means...

"Welding is a joining process that produces coalescence of materials (typically metals or thermoplastics) by heating them to welding temperature, with or without the application of pressure or by the application of pressure alone, and with or without the use of filler materials." and "Welding differs from soldering and brazing in that enough heat is applied to melt the materials to be joined. Soldering uses solder, a lower-melting-point material."

I agree with this. I would probably just say that a weld is something which fusion of base materials is achieved, in order to join the 2 materials.

Now, lets looks at a Cu-Al alloy. Very strong, Not so tough. (fractures easy). If I was to weld Cu and Al together, I would probably get the above property, rather than the properties of copper and Al together.

I used an inert Ar chamber with a tungsten electrode and about 40 amps. I clamped the copper sheet against an Al sheet, with the Cu sitting a little higher than the Al. The idea was to arc the Cu since it can move heat more quickly, and has a higher MP. The heat it dissipates should run into the Al, which also gets rid of heat rather quickly, so so this must be done before heat is saturated in both metals.

1st try. had some grounding problems because I didnt put a brass block against the metals. crap. oh well, try it anyway. I achieved metal fusion about 1 mm by 1 cm. A larger area was effected by the Al slicking onto the Cu.

2nd try I folded the Cu sheet ontop of itself to get it thicker. clamped it down, placed the grounding block this time, and went at it. Results show fusion around the points where the clamps sat. I think Al used capillary action to run into cracks in the Cu and were followed by more heat on the Cu. So I think the Cu melted and in with the Al present.

I snapped the plates apart to find copper had crossed into the Al plate, and Al was all over the Cu plate.

3rd try. Started the arc and realized that the clamps were too close, but it was too late. The chamber filled with burnt paint/zinc fumes. I pulled the vacuum to suck it out, but it of course comes out the backside of the pump, and into the room. *cough*. so after that I shut down for the day.

I want to find some thicker copper sheet and try it some more next week. I certainly don't see this method of joining the Cu and Al practical, since the joint made not have the play that Al or Cu does, but I will place a good join on my desk for sure.

Gomez inspired me to post my project listing. While mine is not nearly as impressive, nor full, it really needs to be documented so I can start killing some of them off.

I separate things into long term/ongoing things, medium term(things that require a bit of planning and time to carry out the gathering of materials) and Short term. (stuff I where quality can suffer a little and use what I have for materials, with what I have as tools... Hammer... duct tape)

Long Term, ongoing.
-Arc Melting Database. A listing of alloys I have made, with the results for reactivity, vapor pressure, homogeneity, problems that arise, etc. I want to include Photo's too. This begs that I purchase a cheap digital camera that I can keep in the lab.

-Elasticity project. This looks at inexpensive materials that can be produced at the size like my arm, which show excellent elasticity vs force.

-Foundry Sands Project. This was a small research project intended to explore the best casting sands available for different metals, how to make the sands inexpensively, how to generate a well rounded sand which Joe-Internet-coffee-can-caster can make and use. (explores single cationic binders, Polar/NonPolar chains, rather than Swelling clays which suck ass for casting anything but Gallium)

-Cool Elements/Compounds collection. Its a collection of Pure metals (only need like 18 more pure metals to complete it) Metal oxides, Salts, etc. I make crystals with whatever I can and plan to make other minerals with my new heating unit. This is a good backup project when I am bored. Its interesting to see how the color of a metal oxide will change by adding one oxygen to the compound. (yes I know how color works in metals), but its neat to look at say WO2 vs WO3.

Mid Term projects.
-New Arc Melter/inert chamber/inert welder/ imposed arc / direct arc casting unit. I am still looking for materials for the seal and compression method. I want to be able to take the chamber to a positive pressure of 15 atm. (in an attempt to compensate for some crappy Vapor pressures on Mg or Zn.)

-Cloud Chamber. The classic. I just need to make the damn chamber. I have some plastic, but need to figure out a way to cut it with some accuracy.

-Block-Bot-Furnace. This is a fun little guy. I have him taken apart in the basement lab right now, awaiting a a patch, a new hole and some more planning. I need to find some Silica Colloidial bonding stuff. The shell of this furnace is 3/8 steel, welded up in a box on casters. (the shell alone is around 100 lbs). I used to use a firecement, but I stripped that out a few weeks ago and will replace it wil ceramic fiber, packed down. I have about 14 lbs of this stuff. I will pack the crap out of it, but then I need some sort of insulating cement to keep it from expanding on its own. That and this is the stuff that if you breath, your screwed, so I want to protect myself from silica dust in the future usage.
(oh yea, this is a propane, forced air furnace intended for melting up to Cu, and metals withe lower melting pts.)

-Forced Air/Imposed Air Burner tests. This goes for the above project too. I will lay out some variables and try to find the most efficient rates. (Things like Gas velocity to Air in lower chamber of burner, gas/air mix velocity in upper and flare portions of the burner, what the optimal flare is, burn ratio inside furnace. (like what temps can be achieved when you consider the products and reactants, in an elevated temp, around interference. The rate of efficiency changes as the temp of the environment changes, so I either need to look at a way to change the burner configuration mid burn, or find the best max temp burn ratios. -- Waiting on new thermocouple... the last one met its demise in a CuO thermite rxn.

-Investigate Electric Furnace or Gas furnace for a special Glass Furnace.
The ThermosInconel-Ta walled furnace will provide an environment to melt glass without having to heat things up for weeks at a time (as the campus runs its glass furnaces for months at a time).

-New Metals cart. A cart which can hold all the steel scraps I have collected. I made a metals cart a few months ago, but I have outgrown it, now I need something much bigger.

-Bender. I had been planning on making a frame, to utilize a 6-ton car jack for bending pipes and related materials. However, while looking at the jack last night, I determined I can make some addons to the jack itself and have it do the bending on its own. I am quite pleased with the new design.

-Twister. basically a clamp on either end of a sliding square tube. one with a large torque handle. Turn. twist. be happy. I am looking for another clamp. I found an old Vise thread, so I will use this to compensate for the reduction in metal size.

-Work table. I have so much space in this building... like so many rooms I work out of, that I want to make a small custom cart/work table that I can cart around with me. It should have some basic tools and ability to hold gas cylinders, plasma cutter or Mig welder.

-Plasma Cutter. its like a project because I am still waiting for materials... like Money, so I can go buy one. I am looking at the Hypertherm 380.


Short term.
-Plaster Cart. A cart with dumping function. to dump out dead plaster which is pretty dense. waiting on one piece of sheet metal. I will check my dumpster again soon to see if anything fits the need.

-Castings... Christ, I have like 20 castings I am supposed to make. given that the furnaces are all out of service right now during the move, I am looking to get my blockbot in operation. I can then at least do some smaller casts.

-Sundial. a gift that met a demise when I ran out of O2. I might scrap the current plan and go with something more stable and artistic.

-Stapler of death. I might scrap this since if I can't get the punch to line up correctly. Otherwise it works great. But when you staple, the punch sticks, and thus doesnt retract to go again.

-art thing which im not sure what it is yet.

-Shell plant colony .

-Fixture for my powerbook. I need to encase the shell with something more rugged than the powder coated Al shell Apple provided me with. There are warps, bends and scratches all over it. I want to take the bottom off later today and see if I can bend stuff back. Was thinking about surface hardening a mock shell. (Dont want to mess up the computer case)

...more... stuff...

I just realized I have 2 plots open on my project board, but really, the above stuff is plenty of work. The question is, do I want to do it or not.

Hi, I'm new...and have lots of ideas.

I came across this interesting idea in a book about wormholes and stuff. First, you make two space-time rips. You put one in a room with you, and the other in a shuttle of some kind and make go around the earth at the speed of light. You walk through, and end up...somewhere? The only problem with this is that it pretty much 100% unpredictable. If you could somehow go back, though, it wouldn't be much of a problem. I guess just space-time again and do the same stuff. You should't end up in the past, you'll either end up in the future or just another area in space. Any thoughts?

[ mood | curious ]

once more, my wonderful idea's are smothered by dead smart guys. The idea of pushing the specific gasses through the heat of an arc, to break apart and produce new molecules has allready been done. once again... it was about 100 years ago. This time Birkeland and Eyde beat me to it. Once again I am not discouraged from completely resolving the problems on my own(with my knowledge of pysical chemistry, and a little help here and there from smart people) and reproducing my own version of the experimental proccess.

Current problems include:
When testing the reactor, I will no doubt produce O3. Despite what I find online about Ozone being a good thing to make things smell nice, I know it is very very bad for this level of our atmoshphere. I will not procede with reactor testing until I can figure out a way to deal with the ozone production, either by means of a catylist (as done in the cats in your car), or... mixing it with directly with something to make 02... I figured out that O3+CO -> CO2 + O2, however upon looking up this equation I found that it also produces energy (makes sense). Need to find out if that energy is going to be... "bad" energy for a small space.

I also need to come up with one way gas valves. I want to use something like whats on my particulate mask. I also need to find powerful enough air/gas pumps that will resist any corrosive compounds formed at any point. I am looking at aquarium pumps. maybe I can pick up some from ebay for cheap.

Need to test condesners and bubblers for the different products I plan to make.

Anythoughts?

and here I was, onto something great. A way to make a strong exothermic reaction happen such that you could weld and cut metals. A chemical reaction that would not require any gas cylinders or large arc producing machines/power supplies. This would allow cuts and welds to be made in issolated conditions etc. And then... I found out some dick named Hans Goldschmidt beat me to it.

In 1903. almost 100 year ago Hans of Essen, Germany invents Thermite Welding. I guess this proccess is still used today for repair and joining of railroad rails. (at least in countries besides the US, I beleive we use a different proccess)

Oh well, I am a big fan of re-inventing the wheel. So I have a stock pile of aluminum scraps and such so I am pretty set there. I can just grind some down and collect it. Now... getting the Fe2 O3 will be a bit of a challenge. I found a steel sheet and put it outside after I wet it down. This was going to take a year to collect enough to get going. So I decided I could use the rapid oxidation from electrolysis. I thought about using regular tap water thinking there would be enough crap in the water to make it conduct but decided to just mix some crushed NaCl in. I hooked up some leads to the power supply and tested it to see if I got bubbles at all (and to make sure the black lead was in fact positive)

Yay bubbles... wait... wait... no more bubbles, what the hell? oh yea... I guess it would collect on the anode which at the time was bare copper. I cleaned off the copper and attached an gator clip to it. I eventualy just used 2 iron nails for both the anode and the electrode.

I let it be for about an hour and came back to find that one of the gator clips had fallen in and started to... break down its surface. the surface of the water itself was a thick slimy rust! and a thick layer on the bottom too. woohoo. I will let it go awhile longer and snap some photo's then let it dry.

Then I will probbaly use my torch... or... maybe something else (heh) to heat up the iron oxide and add the Al to the dry mixture. I will put it into the container labeled "danger" and test it. Probably ignight it with acetylene. I am not sure what the test conditions will be yet. I thought about grabbing some .25 inch steel plate and seeing how many it will go through. then test to see if I can control the temp, and maybe mix in some fluxes to ensure a good weld.

Has anyone done a highly exothermic rxn like this before? any tips?

cold sound. [04 Apr 2004|11:04pm]

midchaos
[ mood | tired ]

What property of a material gives it its resonant frequency?
If sound(wave) can excite the particles in a said material such that it makes the material rise in tempurature, what could be done with the same, or multiple waves to make the material drop in temp? or absorb heat?

would you even need to lower the temp?

I was looking at some technology that uses sound waves as the base component in a refrigerator. This made me currious.
maybe it works around the principle of make the temp of the material have a large enough difference between it and the room temp, that it can create a gas exchange (like in a sterling engine) and use the properties of the gas to act as the cooling agent?

Hey, want a fun state of matter, phase change exploration type experiement?

Mix some cornstarch with some water, add food coloring to make it a bit more fun.

Then play =)

it's a very fun mixture. It looks like a liquid but is solid on the bottom. When you add force ie pressure the liquid becomes a solid but once the pressure is gone back to a goo it goes =)

Still looking for iron fillings. I wondered if I could replicate something like it by snooping though the shit can in lab. We dump all of our floor wastes into this bin. a lot of it comes from the steel and flux from the welding that goes on. maybe these super find iron/dust particles could work for my Ferrogoop? hmm I will collect some tommorrow with a hard drive magnet and a notecard(so that I dont have the fillings stuck to the magnet forever. that way sarah and I can test it this weekend. I will post any pictures if anything cool happens.

I got a little info for the physics of arc welding. Mike R. didnt know much about the technical jargon of how the filler rod is deposited.
-Some speculation goes that it simply is heated, melts off the rod, falls due to the greater gravitational pull, falls into the molten puddle and solidifies as the arc moves on (it cools)
--The problem with this, is when you do an out of position weld... like say, overhead, or in a vert position... gravity would have the melted filler do other things besdies go into the weld.
-Ok, so what if we say its the magnetic properties? the polarity pulls the magnetized filler rod into the base plate.
--But there are non ferrious metals that can be welded with an arc.(and all filler rod is like the base metal)
--There is also AC, and DC Straight polarities... so if the above was true, the base metal would flow onto the stick.

What I think is its a combo of both idea's. As some positions I guess specificaly run one of the polarities and not the other. in the flat position you can run any of the 3 polarities. I assume maybe in the overhead you can only run DC reversed? maybe in the flat position, it does just melt it off and allow it to fall into the puddle. and in an overhead position, maybe it uses... say like eddy currents to spit the molten filler rod at the base metal? dunno.

I am pushing back the alternator stuff, and putting time into reworking my electronics workbook. (I found an empty notebook) and I will just fill in about every term and formula I know, and add them as I go. then I want to make a relational database and connect all those formulas and junk. Maybe I can get sarah to make it into a program for me on my computer. I am sure they exsist out there allready, I am sure this is a fractal idea here. Then I can plug numbers and it will convert and translate everything for me :) If this works, I want to make a general physics paradigm in the same manner. Then I want to build a 3D object with wire and small blocks that have the parts of the formula's etched onto them.

As for the alum insulator test. I initialy threw it out, because the melting point of alum is so low. but then again, the price of alum foil is sooo low, that I could infact use it. I need the furnace to get hot enough to melt the alum anyway, I could use the Al insulator in the mean time, to get it up to the 1,500 F. and once to that point, if the Al foil melts, who cares! :) -- I got some graphite/clay crucibles cheaply on ebay. (about $10 a piece) pretty good price when they normaly go for $30 a pop.

[ mood | confused ]

I made a second Mobius Strip the other day. I will easily trace my finger along the single edge/ single side of the object, but I am still simply not convinced that it only has one side? anyone have thoughts on this? Is it perhaps just my brain telling my thats not right? some natural instinctive ideal that it will not let go? could this shape really be a single piece of material that never ends, and yet you can touch 2 points that are more than 38 inches apart, at the same time?

To pinch and object and have your index finger on the same side as your thumb 3 feet apart? This seems so out there, but I could simply touch two ends of a coiled 50 foot rope, even it its not a single sided continous loop.

stupidness.

*clarified*
Ok, like fingers on the same hand. like I could use my index finger and thumb on my right hand, squeeze the the face(s)of the object, and they would be less than an inch apart, yet they would be more than 36 inches apart.

Can we say... Wormholes anyone?

So what happens

sorry sarah that you have to see this twice...

I keep finding more and more things to research on, than I do getting the actual research.

new things on my mind...
FerrofluidWhile Sarah and I were speculating about inductors, I thought to myself, how cool it would be to actualy SEE magnetic fields. I based this against the way fractals are represented on a graph. numbers/plots that fall into the prescribed number set, are colored black, and numbers that are outside the numberset, are yellow/whatever else. I thought... hey.... I bet theres gotta be a way to "color" the magnetic fields, so that we could see them.
I remember back from my Telephony training that a new linemans handset had a Ferroil used between the carbon granules in the speakerphone to make the sound more crisp. I remembered that it was basicly iron in oil (hence Ferroil) and after a little online searching I found this Ferrofluid.

I think I can make my own with Karo syrup and iron fillings. I want to research what oils could be used. what other liquids could be used? would Bromine be mad if I mixed it with iron? would Homeland Security be mad if I bought Bromine?

AeroGel & Aluminum Insulators after thinking about how it might be cool to make something that would mimic the properties of aerogel to insulate my furnace and make it 600% more efficient, I strayed away from that and picked the properties fo Alum. I just have to find a way to be able to use, without it melting. (thank you sarah for the alum foil idea :)

Physics of how an arc deposites stuff into the weld. (with an arc welder)

more Hallow core inductors. and... I want to gather materials so I can start
Low RPM alternator tests with surplus hard drive magnets

This could be used to gather electricity from a Stirling engine, or from the windmil I want to attach onto the area of my backyard that gets a lot of wind traffic.

Who thinks I should start yet another community for this crap? would you join it?(since thats where I would post :P most of the time.

Errg...

Push me, and then just touch me.Till I can get my satisfaction.

I so want to just learn shit 247/ and play and experiment with crap. what can I do to get to that point I wonder? what can I take out of my lifestyle to get to that??

Ok learning time. (Learning time is subject to disproval, because I might be full of crap)

Sooo... Iron. its cool. Fe is its symbol. I might use it later. just so you know. (to clear up carriers, when you hear the word Ferrum or ferrous, or ferric as in Ferrous/Ferric metals... it means metals that contain iron. Iron's base word is the Latin Ferrum. I think I remember knowing that in Latin it means holy or something. (used for the purposes of holy conquests... the tools/weapons anyway)


We are going to step back in time to about 1250 CE. To the forges of the time. In Europe, most of the tools of this time (swords included) were made from Iron Ore. We are going to learn about the "direct process" in which was used to make iron tools. The difference between the "Direct" and "Indirect" is that, the indirect smelts, purifies, and then casts. This method has been used for the last 100 years or so. The Direct method, simply like said above, where the tools are made directly from the mass or iron ore collected.

How was this collected you ask? I find this very interesting, and that’s why I want to share it with you :)
Basically in the early times of the direct process, they used charcoal in alternating layers of charcoal and iron ore. So you would have a layer of just the carbon fuel (coke I assume could be used too, not that they had coke at the time)(no that’s not a drink), layered with the carbon based fuel and the iron ore. This made several layers, and then the "core" was surrounded by more charcoal(carbon fuel). I keep saying carbon fuel, because its very important. It basically had 3 purposes. 1. To supply heat for the combustion process. 2.to allow carbon to react with the oxygen inside the iron ore(and help purify it).3. To shield the hot iron crystals from oxygen in the outside air (preventing it from rapidly oxidizing). soo... how does it help get the oxygen out of the iron, as well prevent more oxygen from getting it, while oxygen is being pumped in to aid in the combustion process? Yay Chemistry.

Oxygen would be pumped into the heart of the charcoal/iron ore core. Probably with some sort of wind generator or a bellows etc. This would air containing probably 20% oxygen would assist in keeping the temp of the burning coals hot. As the oxygen would assist in the combustion of the charcoal, it would produce Carbon monoxide (CO). the CO would travel up through the hot core passing through the iron ore layers and would react/combine with the oxygen inside the iron ore. (Fe2 O3) to produce carbon dioxide (CO2) which passed out the forge into the atmosphere(ready to be consumed by plants :)

(the CO is kind of unstable, so it wants to join with the other oxygens in the iron ore, to make the stable, CO2)

does that make sense?

This would help make the iron more pure ( for this learning time, we will not touch on other impurities, because its not relevant to where I am going with this)

anyway, the fire (as I have learned) does not get hot enough to actually melt the iron from the iron ore. (iron is around 2800-3000 F. ) and our fire (my fire if properly insulated with proper air intake got up to around 2000 F. I am sure you could squeeze a few more hundred degrees out of a fire, but not enough to actually melt the iron.

So how do we separate the iron? Well the tiny iron crystal clusters would break their form and fall (with the help of gravity) into the bottom of the furnace. This allowed the pure iron to collect at the bottom, as well as the not-so-pure iron (with impurities). but the pure iron is more dense and would settle at the bottom, where as the lighter slag would form at the top. the Slag was wasted iron. But it did have its purpose. It could now protect the vulnerable iron from oxygen in the air. Over time a spongy iron mass would form. This form, was taken, and hammered to try and squeeze out as much slag as possible. The process needs to be hot so that the crystals can move more readily, and the impurities can be forced out, by the crystals forming in their correct places. (thanks Sarah for the helping tidbit of knowledge :)

The load of iron would be hammered and hammered, and reheated and hammered again, (much like you would see in a movie where they are making a sword. Folding the iron and hammering it again and again. This is to help the crystals form into their correct places. (thus making it stronger) we can show this by taking your hands perpendicular to each other, and trying to fit your fingers together as best you can. If you keep your hands straight... you cant. You can get a few fingers together, but the rest have large gaps. Think of your fingers as the iron crystals. and the gaps as impurities. you are trying to make your hands so that they are facing each other, and your fingers can comfortably fit into each other with no gaps. Then the iron would be cooled slowly, probably by putting it into sand or dirt and letting it sit until cool. In the movies I always see then pounding and then quench the piece they are working on in water. I do not understand this. Maybe someone that knows more about that should tell me why they do that, because in my understanding, that would be stupid. You want the crystals to form and settle on their own as much as possible. by quenching it, your ramming the crystals into each other as if your hands were not lined up. ahh well.

Now then. I tried to replicate part of the process above. No, I did not fire up the old furnaces (because they all died). I substituted the charcoal with parts of the below process.

Acetylene + Oxygen = Carbon Monoxide + Hydrogen

C2H2 + O2 = 2CO + H2


Carbon Monoxide + Hydrogen + Oxygen = Carbon Dioxide + Water

CO + H2 + O2 = CO2 + H2O


We get 2CO from the oxy/acet combustion, and the CO does go back into the second reaction. remaining CO's go into another reaction with other oxygens that are a part of the rapid oxidation of the iron. which forms CO2 as well. anyway, we are left with the particles of oxidized iron, and tiny tiny iron droplets. (much like the slag coated iron that we find at the bottom of a furnace in the year 1300 CE. I collected some of this... (at the time, spongy white iron) now silver/grey spongy collection of droplets. I blasted iron onto a plate about 5 inches away from the jet.


Here are some of the pictures I got. :) ( keep in mind, you cant see the crystal structures, becuase my microscop simply isn't that cool. That, and I would need super thin slices, which I do not have. (thank your sarah for that other tidbit ;)
If I took the estimated price of my camera and added 2-3 zeros to the end, then you would be looking at the price of a microscope needed to see that stuff. and I am sure I would buy a bitchen new computer, before I bought a bitchen new digital microscope that could take resolutions up to 1280x1280 at 900x zoom. :)





Go here for the rest of them.

Ahh... along goes the propane foundry project. I bought propane today and made a few tests with the new burners we made. After a few fireballs, I was able to get a very nice neutral flame out of it. The next post should have some pictures of the 1st time I use the thing.

hmm. I really should split up the community so that Idea's are in one place, and this crap is in another. oh well.

Something I have been thinking about alot on the issue of tachyons violating causality... They cant. But I think I find this becuase I attack both Causality and the speed of light, instead of tachyons themselves. Perhaps I am tweaking the rules of the game to make my argument realistic. oh well.
more on this later. Time to go study calculs *bleh!*
