Such low tech traditional production methods and the wrappers have bar codes.

Great idea, but you can buy a nerf vortex for $10, hollow it out, and put your gopro in it.
These guys have obviously practiced their throws to be able to keep it pointed in the right direction and not spin. They did far better than I thought they would.

Every clip they show of this amazing laser-guided precision weapon disperses randomly and misses 90% of the vehicles in the target zone.

Seems to me the lasers, rockets, computer chips, etc. are a bit wasted.

Typical American military. Spend $50 billion on a weapon system which is barely better than the simple low-tech solution and poverty-level wages for the people who will deploy it.

But it's just political show for the masses. Look here, we do something about our shitty police! That's the sad part.
That won't stop cops from showing up with SWAT teams at your house because you didn't pay parking tickets.
The problem isn't being run over with a tank or getting shot to pieces by .50 cal machine guns. Any sensible law enforcement officer working in the US should just know that this is ridiculous overkill. They're not fighting Terminators or Transformers, they're fighting fleshy, squishy humans.
And here's the real problem. They shoot people with handguns and kneel on their throats. They spray you with mace or beat you with sticks. They use somewhat low tech weaponry to cross the lines.
The only field where that military equipment could become a real problem is in mass-protest situations. Just look at the occupy protests. However, teargas, riotgear and batons are still the very effective go-to-solution.

Pakistan, yes. I think we have at least a small force there. Not at all sure about the others, but likely we've got some there.
Those are not the only places we've droned, not even the places we've droned the most. Try Afghanistan and Iraq. You just hear about it more when we do it in places we aren't technically 'at war' with.

It makes little difference what the delivery system of the explosive is, that's why I always wondered what the big deal is about suicide bombers. They're just another delivery system, a low tech, radar cloaked delivery system. It's the bombing/indiscriminate killing that matters. Right? Not the delivery system.

Drones have their proper uses, and improper uses. Bombing someone you can see is setting up a booby trap to kill you or allies is appropriate. Bombing people based on their height is an improper use. This has little to do with the drone, and more to do with the leadership and their 'rules' for who's a target. For me, it's not about 'drone vs manned aircraft' though, it's 'giant bomb vs precision assassination'.

Do you think Obama is watching a little screen deciding 'bomb that guy, and that building'? He is not involved at that level, and you know it. I don't trust a disinterested tech thousands of miles removed from their actions to do the right thing, they've proven they can't be trusted, and they're the one's that matter in this instance. That said, if there were much better rules for engagement and they were draconically enforced, I would have little problem with keeping expensive planes and pilots out of danger.

Incredible. How did he start the holes? Just pound in the spikes little by little? Also, it didn't look like a very straight cut, which probably won't matter for his purposes. I absolutely love low tech like this.

@enoch - Specifically, what new power has the government gained here? (this is not a rhetorical question)

I'm with you on torture, warrantless wiretaps, illegal wars, assassinations (in general, thought I think Al Alakwi was justified considering the body count he had racked up), persecution of whistleblowers, persecution of journalists

The current NSA scandal encompasses none of these things. If they want to record your phone calls, they need a warrant. They didn't under Bush - but they do now - and PRISM can't go after your internet data at all.

Even if they did want to grab everyones' information, can you see how difficult it would be to pull off? How many phone calls are made in a day? (millions?) How many warrants would it take to get access to all those calls? How many man hours would it take to record and listen to all those calls? Even if the NSA were full of villainous mustache twirlers, doesn't that seem like a futile task? 99.9999% of the information would be useless.

I believe that the NSA genuinely works to stop terror attacks. I know there has been much bullshit done in the name of the "war on terror", but I believe there is a genuine need for an Agency that deals with National Security. I would imagine most countries have some kind of similar body.

I don't have a problem with information gained through search warrants. My major complaint is that this stuff is not better explained to the public. I know that there is plenty of specific information that needs to be kept secret in order to not blow the cover of agents who are wiretapping suspects, but I think the broad strokes should be put out there. Here's what we are doing. Here's why. Here are the problems we've had. Here are the successes we've had. How are we doing? How can we improve this?

I also think there would be far less need to monitor if drugs were legalized and the war on terror ended.

Anyway, I think this kind of surveillance is going to become status quo, will not be overly problematic and will be completely uncontroversial in a few decades. As far as abuse goes, you don't need any of these high tech contraptions to listen to people's phone calls and track internet usage. These things can be done fairly easily with comparatively primitive tech that can be bought legally at spy stores.

@criticalthud I don't disagree with what you say. My point is that judge approved wiretaps and internet surveillance should be a legal part of the law enforcement/National Security arsenal. How to do it best is beyond me. I think warrants and constitutional protections are decent checks and balances, but I know they are not infallible. As I mentioned to enoch, if someone wants to listen to your calls, be that person a high ranking government agent or your grumpy neighbor, it can be done easily with low tech. Killing these guidelines would do nothing to protect you from a rogue agent or personal vendetta.

If all this leads to a real discussion on the war on terror or the war on drugs, I'd be thrilled. My prediction is that it will just be used as a politicians electoral bludgeoning device until everyone gets sick of hearing about it and it slides off the radar screen.

Seems a little low tech for the casting. I would of figured it was all automated by now. Still it's interesting to know how these are made.

To continue this lesson, it is important to note that most bomb technology doesn't use enriched uranium alone. The other key material compound is plutonium. For all intents and purposes, all plutonium is man made (with only traces of 244 found in nature, of which is completely unsuitable for weapons..Pu244). Plutonium is usually needed in a bomb because of its much lower critical mass. This lower mass makes bomb fabrication easier, but that creation of plutonium is by no means trivial.

You need huge facilities, dedicated to the sole purpose of uranium exposure. Like the video mentions, normal uranium is mostly U238, this junk gains value in the creation of plutonium. Weapons grade plutonium is a special isotope of plutonium, Pu239. This need is very specific, the different isotopes of Pu can have so very serious implications for bombs. Lets go over them as we as we go over how uranium is exposed to make this very special isotope

First, we start off with U238...the fuel stock. This isotope is bombarded with neutrons. These neutrons are occasionally absorbed by the uranium, turning it into U239. U239 is highly unstable, and quickly decays (in 23.45 minutes) to neptunium 239. This will in turn, decay into Pu239 (in about 2.3 days). Sounds easy, right? Not exactly, neutron absorption isn't something you can control with ease. What I mean is, there is little to stop our Neptunium or Plutonium from absorbing neutrons any more or less than the Uranium (in fact, their absorption cross sections are typically much larger...they are more hungry of neutrons than uranium in other words). When this undesired absorption happens, the neptunium and plutonium eventually becomes Pu240...and that is a big problem.

Plutonium Pu240 is HIGHLY undesirable in a bomb. Pu240 is a medium lived isotope of Plutonium, meaning it decays pretty quick, but it is HOW it decays that is the problem. Pu240 often decays by spontaneous fission. Having spontaneous fission in your fission bomb is just as undesirable as it sounds. Firstly, all even number isotopes are poor fission candidates, so for every even number isotope in your bomb, that lowers the bombs over all yield (because they prefer to fission themselves, and for very little return energy). This is further complicated by high densities of Pu240 causing your bomb to prematurely detonate, ya...bad news. The levels of Pu240 represent yet another challenge in the level of heat they generate from their rather quick decay, though, considering the previous 2 issues, this one is less problematic, though still troublesome. And lastly, there is nothing stopping our Pu240 from absorbing yet another neutron causing yet another isotope of plutonium to arises, namely Pu241.

Pu241, being an odd numbered isotope heavier than lead makes it a rather good subject to undergo fission. It doesn't have the same set of problems as Pu241, but it rapidly decays (14 years) into Americium 241, which is not fissile, and has a halflife of 432 years. These factors add large amounts of heat to the bomb, and reduce overall yield, as well as detract from critical mass.

The solution for this is a very low tech, time consuming, laborious process with produces tons of waste and very little plutonium. One has to expose small blocks of uranium to neutrons under a very brief window. The brief window decreases the chances of undesired neutron absorption and negates much (but not all!) of the heavier forms of plutonium being created. After exposure, they are left to decay, then after a few months, are chemically processed to remove any plutonium and other undesirables (this is also very very hard, and I won't even go into how this is done), then re-exposed. This yields gram(s) at a time. To make a weapons, you need 10 killos, at least...for one bomb...if everything went great. This means you need HUGE facilities, HUGE staff, and HUGE uranium resources. Your facility would be obvious and serve no other purpose, use tons of energy, and pile up radioactive waste of the kind no one wants, heavier than uranium wastes...the worse of the worst. No such facility could exist alongside some traditional uranium facility and not be noticed, period, end of story, done.

We haven't even covered bomb making problems, of which killed some of our top minds in our own bomb program. A set of incidents revolving around a specific bomb type, after taking 2 lives, was dubbed the Demon core. These are the reasons over half the budget of the DOD gets soaked up in nuclear weapons, and we haven't even covered some of the more important aspects (like delivery systems, one simply doesn't walk into Mordor). Nuclear weapons are hugely expensive, hugely conspicuous, require massive facilities and require a level of sophistication that is completely absent from the training of reactor nuclear scientists.

Reactor research and materials are orders of magnitude different from weapons grade materials and research. No bomb in history has EVER been made from reactor grade plutonium because the levels of Pu240 and Pu241 (and we haven't even covered Pu238!) are blisteringly high, way to high for weapons. Isotopic separation for Pu would be even more costly than uranium because of their mass similarities (compared to U235 and U238) and need a different set of enrichment facilities specially tailored to plutonium enrichment, of which all the people who knew something about that are Russian and American, and most likely dead or work classified to the highest degree.

The problem of nuclear weapons via reactor development is all a game to ratchet up the fear machine to get a particular end. It isn't a technical problem, it is a political problem. In the end, though, emerging technology could make enrichment easier anyway, so many of the issues I mentioned might eventually fall to the wayside (not within the next 10 years I imagine; for interested parties, google laser enrichment...coming to a world near you, but not exactly tomorrow, it's awesome stuff though). Eventually, the US is going to have to get used to the idea of more and more nations owning the bomb...but that issue is completely unrelated to reactor design and research. Reactors and nuclear weapons share about as much in common as cars and space shuttles...trying to link them as a dual proliferation argument is a political game and doesn't map on to them technologically.



I should note that I am not yet a nuclear engineer, but I did stay at a holiday inn express.

I remember people making fun of me back in gradeschool for doing the low-tech equivalent of walking-while-texting: walking-while-reading. I was good at it though, I don't recall any incidents of falling down stairs and/or wandering into traffic, etc.

Then again, if I had managed to pull a cunning stunt like that, the likelihood of being caught on news camera or somebody's mobile camera would have been slim to nonexistent compared to now. The internet age -- if there is one thing it had ruined, it is plausible deniability in these sorts of situations.

This is a surprisingly deep allegory of the Lost story, Ceiling cat just created Basement cat, like Jacob created the black smoke.

I find the directors use of low-tech camera work very compelling and rate it 8 thumbs up.

OK. I take your meaning about proof of concept for the 3D glass printer thing, but for this particular one, at no time will consumers at large accept paper products with burn marks around the edges. They'll have to be cut off, and then it would make more sense just to cut it with a blade in the first place. Now, that blade could be sun-powered, but that's a different concept.>> ^MaxWilder:

All that plastic and metal, on top of that driving out to the desert and back, not to mention all the materials consumed in designing it, to do with solar power in a few hours what you can do better in a couple minutes at home with a pair of scissors and a hole-punch.

Wow, you are so missing the point. This guy is doing proof of concepts. Of course it would take resources to set up, but once it is, you could use nothing but solar energy to do what factories are burning fossil fuels to do. Indefinitely.
Of course his machines are very crude, but his goal is to get people thinking about utilizing free and abundant resources of the desert. Others can refine the ideas however they might want to apply it.
