See post 34 and 35 of this thread.

You dont have PHP installed (or its not working).

I hear ya. Among others, I still got an old (oil cooled!) GSX750F in my garage. Its no longer in driving condition, been thinking about lending that oil cooler.  But  Im worried it might be corroded and contain lots of metal particles. Think its safer to buy something new.

People still need to refill their gas tanks, there is no obvious trend against that. Come the day solar powered cars become mainstream, good luck opening a gas station + shop that also sells foods and drinks.

There are still companies that make money producing and servicing pay phones. You can be successful in ANY market, that doesnt mean its smart to pick a business that serves an evaporating market. But go ahead and prove me wrong, then and only then, feel free to call me an idiot.

Yeah, but does that make for a profitable business? If your profits are going to come from coffee and drinks, you have a large and expensive establishment that will serve precious few drinks compared to any other bar. I think its a losing business concept and just accepting bitcoin isnt going to turn a losing concept in to a winning one. My 2 cents.

All oil is flammable, so Im not sure what risk the PU (or fibreglass) would add to that. If it catches fire, my shed will burn down anyway. But in case the pump fails, the cards will just shut down, and long before the oil reaches flash point.

Anyway, while I appreciate the thoughts and drawings, Ive pretty much made up my mind. Unless experimentation throws up some unexpected results, I will be using a single PVC container that will hold the cards (im building the first to hold 6 with 2 motherboards), pump, oil and PU foam (if needed, coated with something, perhaps just some oil resistant primer paint). The oil will be circulated to the radiator in my pond filter.  There is no risk in it running dry unless I have a leak, or overflowing, and its a fair bit easier to set up, not too mention more compact and easier to move.

Ive just filled a tiny plastic cup with PU foam and vegetable oil that I will keep an eye on to see if it breaks down. I suspect it will, but hopefully only in the very long run. Once hardened, PU is supposed to be pretty inert.

I will. But dont hold your breath. Im really slow (and not even very thorough) when it comes to stuff like this

My current plan of action; make a mold of sorts in a PVC tub, that will keep me busy for a while; then fill it with vegetable oil, insert a single spare old ~100W nvidia gpu with no oil circulation or cooling (other than the gpu fan). See what happens. I want to see the difference between oil temperature and gpu temps. I want to see how fast the oil heats up, and if that is local heeat, close to the card or if the entire bath slowly heats up.

 If the oil gets hot but without causing the card to really overheat, that would be perfect and Ill keep it running for some time to see the effects on the oil, the card, and measure temperatures in various places in the oil bath. With low ambient temps and a fan if needed, I hope to get there. 70C or so oil temp would be perfect as a worst case test scenario.

I wonder, are you beginning to see the folly of proportional? You are having a long first block, that can happen in any payout system obviously. But who in their right minds would start mining here now? The shares you produce will be diluted by 3M existing shares on this block. Ignoring the bounty (which you can not sustain), every sane person would be waiting for the block to finish, and then join in for the next round, until it becomes longish. Its gonna be like that every time.

That more or less boils down to what I intend to make, except, I dont like so much air. Too much chance of dirt getting in the oil. So fill most of the air in your drawing with PU foam or similar, and replace the freeflowing oil with some inserted tubing and its roughly the same idea. Only I dont have to worry about the pump capacity to maintain levels.

Im okay with fibreglass btw. Its messy, but I love the stuff. But its not as easy as youd think to make it water (well, oil) tight. Ill experiment a bit tonight.

Curious, why do they take helping poor oliver as example, and not say, paying for the military?
Do you think its okay for george to refuse paying for roads, for the police or the defense of his country, or even speeding tickets if he doesnt want to?

If george doesnt like paying for military, or speeding tickets, or helping people in need, in a democracy he has the ability to vote.
If he doesnt like the outcome of the vote, he can move elsewhere. You dont get to cherry pick laws to obey or things to pay for.

@Defkin
I dont have the metal working skills to make something like that work. I dont have any hand working skills really, so thats no surprise . I also think you have a lot of work to achieve relatively small heat exchange surface. And Id still be hesitant to pump pond water through it. All kinds of things are going to live in there and accumulate. Ever seen a string algae blossom?

@DnT and everyone
DnT gave me another idea with his "single gpu container" approach. Its too much work as he put it, but there is an easier alternative that achieves almost the same. Im thinking of making slightly oversized mockups of my videocards with some room for oil flow, position them in the PVC container, and fill it with polyurethane foam.  It will help keep the cards in place, drastically reduce the amount of oil I need, and can help directing the oil flow. I could also embed some tubing to deliver the cool oil right at the fan intakes and remove the oil at the exhausts. Its a bit of a hybrid approach between the video I linked above (splashing oil on the hot components) and DnTs suggestion.

Now Im not entirely sure if PUR foam will resist being submerged in oil for extended period of time. I fear it may not. I know water eats it away slowly (we are talking years, but still), so I may have to coat the hardened foam with something. I have some fiberglass and epoxy raisin I could use, though perhaps just coating it with some kind of oil resistant paint or sealant might be enough. Suggestions?

Im also wondering how to make the mockups and be able to remove them without tearing up the PUR foam. Or maybe I should just fill it with foam and carve out the areas with a dremel or something. Im not much of a handy man so suggestions are welcome

Laugh?

I had the same dream when I was 20. I wanted to start a geek computer shop annex internet cafe. I wanted to use it to give internet and PC training courses too. But that was long before internet became ubiquitous and rendered not only the internet cafe obsolete, but the geek shops too. So Ive long shelved that idea, today almost no one has a need for such a place here. Who doesnt have internet? Most have it in their pocket.

Then some 10 years ago I made a trip across Latin America. I fell in love with guatemala and I ended up talking to an internet cafe owner there that wanted to sell his business, and I was interested for a while. But then I realized that while computers and internet may not be as ubiquitous yet there as here in Europe, it was only a matter of time. Im not sure if that time has already come there, but at the very least the tourists they relied on mostly will have their smartphones and tablets with them.

Also when I look at the prices of the few internet cafe's that have not closed their doors (yet), I cant say it looks like a profitable business. Its a dying niche market IMO. You should have done it when you where 16 .

Agreed with the above 2 posters. Id rather have someone who looks like a real person and is convincing and authentic rather than  someone who looks (and acts) like a hired swimsuit model.  In that sense I found Magda far more convincing in the video.

There is one, its at least 2x faster than anything else out there. The source code is being held by a Nigerian princess who forgot her password. I only need 300 more BTC to bride her IT manager to get access to it. Please send 10BTC to 13vSjKtA17x3FQgCQHMyrk17uPvEgXzxSF and I will share the code with you!

Dont hold your breath. That site only showed that fake miner app. There was no pool, not even a fake one. Yet our friend here claims "one other person" was "mining there". How would he know?

BTW, if his paypal account was indeed emptied, its pretty trivial to find out where it went and reclaim it.

Bye bye Montico. Scammer got scammed, cant feel sorry for you

Wait, you got some random email from someone you dont know offering a 10BTC reward, you "uploaded your wallet" (??), downloaded a binary, ran it on both your server and your desktop ? Are you serious? Can you post that email with header?

Ill be honest. Nothing you say makes any sense. You are supposedly a newbie that has no clue about bitcoin, you never mined before, only now with a miner that isnt a miner but a trojan. Yet you claim to have lost bitcoins?  Moreover I can not find any single reference to this cross miner thing in google, other than in this very thread.

Ill give you the benefit of the doubt, but it seems quite likely you are the very same scammer that started this thread.

Dont believe it. Did you run this "cross miner app"? It was a trojan. There is no telling what else it did, quite possibly a rootkit was installed too. Assuming you are being sincere and not the OP, the only safe course of action is format and reinstall. Consider something other than windows while you're at it.

Also, Im curious.. what was this cross-mining pool? where did you hear about it? How many other people where mining there?

OP=original poster. The person who started this thread. He linked to malware laden "cross miner". Perhaps read the thread from the start. His post was edited to remove the link and his signature was ahmm.. updated.

dani beat me to it, but he is correct. Also, whatever else you do, consider your PC compromised at this point. Be very careful.
