5 Absurd Solutions to Huge Problems (That Actually Worked)

5 Building a Supercomputer Out of Hundreds of PlayStations

The U.S. military needed a supercomputer, but didn't want to spend the millions of dollars they typically cost. That second part may surprise you -- we all tend to assume that the U.S. military is on the cutting edge of all things tech (something to do with having more than a half trillion dollars to spend every year). But they're not just a bunch of big kids buying expensive toys with unlimited budgets -- they have hard choices to make, just like us.

The Creative Solution:

So they bought almost 2,000 Sony PlayStation 3s and hooked them together to see what would happen.

OK, we're being a bit unfair there. Video game consoles have some serious horsepower for the few hundred dollars they cost, so the solution made sense. The Department of Defense's 1,716 PlayStation 3s were formed into the massive computational megamachine known as the "Condor Cluster." This is what it looks like:

For one-tenth of the cost of a traditional supercomputer, the Condor Cluster is also using one-tenth of a traditional supercomputer's power. But instead of using top secret proprietary technology, the Cluster is open source. It's even been opened up to universities, who are using it to do everything from create artificial neural networks to build models that will prove Einstein's theory of relativity.

And here's where the Condor is really creative -- instead of letting one massive machine do all the work you'd expect from one of the world's 40 fastest computers, the system can rearrange its own workload, farming out assignments to idle computers around the world. Not bad for a big-ass pile of kid's toys.

The military is actually famous for this kind of MacGyver thinking, like ...

4 Using Silly String and Shaving Cream to Thwart Bombs

The War on Terror introduced us to a new kind of warfare that involves less open battles between armies and more planting improvised bombs for soldiers to stumble across (for reference, see The Hurt Locker). For instance, when the enemy knows that part of the other side's job is to patrol abandoned buildings, their own job is as easy as planting some explosives and running a thin wire across a doorway to set it off. If the building is dark, there's no way you see the wire until it's too late. Boom.

So how can you detect tripwires in that kind of environment? Maybe some kind of state-of-the-art sonar system? A wire-sniffing dog? A bomb-proof robot to take point?

The Creative Solution:

How about Silly String?

Yes, that multicolored stuff in the can that kids squirt up their noses and jackasses spray out of their fly at parties is currently being used by U.S. forces to help detect deadly explosive booby traps.

You can already picture how it works: Spray the Silly String across and through the entire vertical length of the doorway. If there are any tripwires there, the Silly String will catch on them and hang off the wire -- the spray is so light that it won't trip the detonator in the process.

Silly String isn't standard-issue equipment, by the way -- most of this is the result of one woman, Marcelle Shriver, who organized the delivery of over 120,000 cans of the stuff to Iraq after her son was taught the technique by a group of U.S. Marines.

According to one member of the top brass, this is all completely cool because soldiers aren't forbidden from improvising stuff like this. Which is lucky, really, considering we're also using shaving cream to warn troops about hidden bombs.

After discovering an IED or roadside bomb, troops will simply squirt the damn thing with the foam so that troops following up behind will know where not to step. Oh, and it's also worth bearing in mind that this technique didn't originate from Iraq; one of its first proponents was "Stormin' Norman" Schwarzkopf, who, after hearing that a group of his soldiers were trapped inside of a Vietnamese minefield without any equipment capable of marking the mines so that they could escape safely, ordered an airdrop of shaving cream to them.

The community drive responsible for shipping all of this stuff out to Iraq, Operation Shaving Cream, also recently passed its goal of raising 10,000 cans. And, hey! There's totally a link you can click right here that will take you to somewhere where you donate money to buy more of the stuff.

3 The Navy SEALs Get Literal

As much as everybody loves the Navy SEALs in the wake of the bin Laden thing, we have to admit they're not perfect. Like they can't walk on water or hold their breath indefinitely. And they can't find underwater mines without risking their own asses. So it has to be robots this time, right? They have swimming anti-mine robots?

The Creative Solution:

They're using seals -- not elite super soldiers, but actual SeaWorld-style sea lions -- to assist with identifying underwater weapons and evildoers.

Animals have been used in war forever, but never with this much style. Knowing that sea lions can swim 25 miles per hour and dive 1,000 feet, they're the perfect candidates to detect and defuse underwater bombs. Especially since their natural sonar is extremely effective, according to Admiral Snelson of British Naval Command.

Dolphins and sea lions are trained not only to detect underwater mines, but also to alert the Marines if they detect danger. Some of them are trained to disarm bombs, and some are even trained on how to locate a human intruder and cuff him with a GPS tracker. If necessary, they may even follow the suspect onto land, honking loudly to alert the troops to their position ... which is 100 percent the least awesome way to get caught by an opposing army.

Not that the military has a monopoly on somewhat insane outside-the-box solutions. For instance, if you go to a Russian airport, you'll see them ...

2 Clearing Snow With Jet Engines

If there's anything we know here at Cracked, it's never bet against a Sicilian when death is on the line, and never go to Russia in the winter. Especially if you plan on leaving. The Russian winters (which we were going to joke sounded like a new hipster band until reality beat us to it) have taken their toll on Russia's airports, and as you can probably guess, they make it extremely difficult to maintain the runways with traditional methods.

The Creative Solution:

The Russians are using the one thing that can be used to handle such a situation: mother freaking jet engines. Revel in this, world:

Those are Mig-17 fighter jet engines strapped onto traditional snowplows. They've been used throughout Eastern Europe for the past 50 years; apparently it's the only way to keep up with winter's raging iceboner.

In the 1960s the Soviets had such a snow problem on their train tracks that they were compelled to use jet engines to fix them. Eventually, jet engine snowblowers carried over to the States, where the MBTA (Boston's transportation authority) is using them for the same purpose. Dubbed "Snowzilla," the machine they came up with is used every year to clear Boston's train tracks from snow.

1 Getting Boats Uphill With a Ship Elevator

You know what sucks about water? How it and everything in it is gravity's bitch. When is the last time you saw water walking up a hill? Never. It's lazy. So imagine you're a boat. And you're flowing against the tide and you've got to go up a hill. Don't even think about it -- that violates every law of boat physics.

What do you want, a freaking elevator?

The Creative Solution:

Yep.

Boat lifts, or "lift locks" as they're also often known, are massive structures (shaped like elevators, oddly) that are capable of allowing ships and boats to traverse hilly inclines. The boat in question simply sails into the lift, which locks the boat and water in and then takes it all up to the connecting waterway at the top. It's not a new technique -- the first one ever built was installed near Dresden way back in 1789.

Luckily though, not all of these things look like knock-off versions of Splash Mountain; some can actually be quite architecturally interesting. For instance, there's this one that looks like what would result from the bastard union of a toaster and HAL from 2001: A Space Odyssey:

Or this one that was constructed in Mordor, apparently:

Mercifully, this unholy Scottish monstrosity, known as either "The Falkirk Wheel" or "That Thing That Inspired Saw," just happens to be the only one of its type in the world. If that thing does turn out to be a Transformer, it wouldn't surprise us in the least.
