Yeah, you can drag an AK through the mud, piss on it, pick it up, and fire off a magazine with out a problem (other than the smell). Those things were built tough, and the chamber size allowed them to fire both American and Soviet ammo.

But between you and me, I'd rather take an M-16A2 at 500 yards than an AK at 200 yards. The same clearances that let them run while mud packed and never cleaned also drops their accuracy to crap. An M-16 will reach out and touch someone from 800 yards where the AK was designed to put a wall of lead down range while massive blocks of infantry were advancing.

AK was never designed for long range, so you can't really fault it for that.

Re:Poor estimation (0)

Anonymous Coward | more than 3 years ago | (#35970060)

No, bad design is not the problem because the AR-15/M16 platform is not a bad design. As hitmark said, cheaper ammo was substituted at the last minute by a penny pincher. Specifically, it was the propellant used. It caused massively accelerated corrosion in wet environments. That was the cause of nearly all of the M16's problems in Vietnam.

blair1q (305137) | more than 3 years ago | (#35969594)

Most of it was because it was designed only for firing and carrying specs and tested only in clean conditions.

Jump into a couple of foxholes and you're disassembling the fucking thing to get the sand out from between the bolt and the receiver. Whereas you could shake an AK-47 clean in a muddy puddle and come up firing.

If the ammo added problems, that's the ammo's problem. The M-16 was a weapon characterized by an occasional failure to fail.

Re:Poor estimation (1)

eleuthero (812560) | more than 3 years ago | (#35969140)

I am all for someone starting in on buildings designed so well that they don't need maintenance very often. As a point towards the possibility of this goal, it was only in the last few years that they've had to start blocking vehicular access through the aqueduct in Segovia, Spain--pollution and vibration from vehicular traffic was damaging it. It carried water up into the modern age but had sections destroyed in the Napoleonic wars. I'm sure it had some maintenance, but we could do with more designs like that which allow for something to last with largely original material and no mortar for nearly 1800 years.

Re:Poor estimation (2)

The problem is that we wouldn't know how to build something like that.

In a small city in northern Portugal there was this stone wall (maybe 50ft high) that was erected during the Roman era. Several years ago part of it finally collapsed. So they decided to rebuild it. That bit collapsed within a year. I don't know what's happened since, but I suspect it involves concrete and rebar.

To be fair in the case of the bridges, they probably failed to account for increased traffic over the last fifty years and underfunding of maintenance by corrupt local governments. First one's the bridge buidlers' fault, the second one is the public's fault for only electing spoiled children to run local governments, but in either case I doubt it was so much as out-and-out fraud.

Not really. A bridge in the 60's may, or may not, have included a planner or planners. If it did, the traffic volume would have probably included a planner in the first stage, defining the traffic and thereby the cyclic loading. If not a planner, then there may have been an engineer filling the same role. If there was no planner, then it went straight to an engineer for preliminary design, then another (or possibly the same) engineer for final design, then the final design would have been presented for bidding. There are early and late instances where construction and design were combined, but in the 60s, it was much more common for the two to be separate. Today, they're still separate firms, but may be operating as a team. The general point is that it's not *necessarily* the builder's fault that a bridge failed. It may have been the fault of planners, engineers, builders or even an incomplete understanding of the materials involved.

Your second point is spot on, though.

The link you provided does make it apparent that these pumps can also be used to produce electricity if the pump is placed between a heat source and a heat sink.

Too bad these aren't being used more as part of processes cooling troublesome spent fuel, producing some electricity at the same time.

Solid state heat pump - Peltier Junction?? (4, Informative)

Anonymous Coward | more than 3 years ago | (#35968424)

Solid state heat pumps exist already. It is called Peltier Junction. They are not used because their efficiency is bad.

http://en.wikipedia.org/wiki/Peltier_effect

The COP of current commercial thermoelectric refrigerators ranges from 0.3 to 0.6, only about one-sixth the value of traditional vapor-compression refrigerators

So what is the break through in the little heat pumps?? TFA is completely uninformative on that. It doesn't even specify efficiency of the heat pump.

PS. I've had an open loop heat pump for the last decade, and so far it didn't require "frequent inspection" or "maintenance" as TFA says it does. It comes with 20 year warranty. It is basically just like a larger version of a fridge. The only maintenance I can envision is simply cleaning the heat exchanger once in a while.

Re:Solid state heat pump - Peltier Junction?? (1)

skids (119237) | more than 3 years ago | (#35968724)

I don't think there is a breakthrough... I think these guys are just working on the macro assembly angle of things. I can't see any claims as to better COP, which would make the claims that this would be more "environmentally friendly" a bit dubious.

There is work going on, mind you, on much better TEC and TEG devices using new materials and quantum dots and such, but I don't see any indication in the sources that these people are doing anything other than figuring out how best to package them for retrofit applications. Not that that's an unworthy study.

Re:Solid state heat pump - Peltier Junction?? (1)

queazocotal (915608) | more than 3 years ago | (#35969208)

That's somewhat variable.
Peltiers basically blow if you use them at over half their 'sticker' maximum temperature difference.
At that point, they have perhaps a COP of 1.
At a temperature difference of around 1/6 maximum - they are up to around a COP of 4-5, which
isn't bad at all.
However - this is a delta of 6C or so - which isn't really usable in most applications.
It's worth noting that a COP of 1 isn't useless.
If you can make it cheap enough, you can make a electric heater with double the output.

I should have actually saved the graph I made.
To replicate - go to http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=102-1663-ND [digikey.com] get the datasheet - now refactor the graph into power in vs heat pump capacity over temperature and current.

And when you hit the period when the product is already superseded by the next generation, but still selling by inertia, you will be lucky if it still works by the time you get home with it.

I have CD-Rs and DVD±Rs that are unreadable after (OTOO) 10 years; I have yet to find a mastered/pressed disc that has similarly failed. Viz. the issue of obsolescence I can still read them with off-the-shelf hardware as of 2011.

We may recall things differently, but when I was growing up and CDs were the "new" thing, it was assumed only that they'd substantially outlast cassette tapes (which degraded after a few years of regular use), not that they'd last a hundred years. Perhaps the "hundred years" claim was marketing hyperbole and the outlasting cassettes was the more reasonable widely accepted version.

In that regard they've done just fine; a CD that hasn't been scratched or damaged is still readable after at least a couple decades. CD-Rs and the like are a different story; I printed disks back when having a CD-R drive was atypical that are no longer readable today.

could be useful in Tchernobyl and Fukushima? (0)

rduke15 (721841) | more than 3 years ago | (#35968858)

In Tchernobyl and probably in Fukushima, they have heat sources which will last for a very long time. Maybe this heat pump could be of use there...

Dust? (1)

popo (107611) | more than 3 years ago | (#35968910)

It doesn't take a genius to see that the extremely small form-factor would be especially prone to dust.

The 10,000 year number probably requires some idiotic assumption like "as long as it remains dust free".

I look forwards to the results from the 10000 years of testing to verify this (I plan to live forever) .

Why does it seem like every advancement that could actually improve the human existence is "5 to 10 years away" yet they can produce a new [insert company name here] phone every year?

According to the researchers the heat pump will be ready to launch on the market in five to ten years.

Efficiency? (1)

aes12 (580531) | more than 3 years ago | (#35969180)

They mentioned that they're green because the don't use freon. Great. Most compressor based heat pumps have used something greener than freon for years. AFIAK, compressor based heat pumps are still WAY more efficient than a peltier. So if you replace a cooling gas with a 400% increase in power usage... You lose?

right... (1)

oic0 (1864384) | more than 3 years ago | (#35969366)

Small peltiers will last a long time, because they aren't as affected by thermal expansion as their larger brethren. . They still have horrible efficiency though.

questions: (1)

blair1q (305137) | more than 3 years ago | (#35969442)

1. how does it work? 2. where is the motor? 3. it's generally either the motor that dies, or the heat-sink fins on the coils that crust over with deposits and growths, abd cause it to lose effieciency. does this unit work without a motor? does it not need a heat sink? 4. where is it getting the power needed to cause the heat to flow against the thermal gradient to pump it into or out of the transfer medium that goes to the air exchanger? is it efficient at doing this? 5. who cares how long it lasts if it's less efficient?

I have a new heatpump design that will last till the end of our solar system. ...It's a brick.

It also has an efficiency of 100%!!!!*

* but an efficacy of zero

Any High Tech artifacts that last even 100 years? (1)

AJ Mexico (732501) | more than 3 years ago | (#35969760)

Our technical civilization won't really be "advanced" in my view unless we can and do make things that last a long, long time. What technology exists that is still working or workable after centuries or millenia? I think there are a few telescopes over 100 years old that are still in use. Pretty impressive. Older than that, and what?... Stone knives? I heard irrigation ditches and terraces have worked for 100s or thousands of years, but these are pretty static, and have required intensive labor to keep them operating. What *could* we make that would still be operable and interesting in, say 500 years?

Roads? Maybe not the way we build them now, but the ancients sure knew how to build 'em. They might be buried, but all you do is uncover it and you've got the same road as a few thousand years ago.

Freon, toxic? (1)

lotho brandybuck (720697) | more than 3 years ago | (#35969788)

AFAIK, freon and many other of the refrigerants are no more toxic than water... you CAN drown in them, and that is a hazard in enclosed spaces. And some of the refrigerants were ozone depleters, but the new stuff isn't.
