Hey guys, Great show! Very entertaining and would like to see another superhero episode.

But do me and the rest of the fans a favor and step up on your safety. Neither of the guys were wearing helmets and both of them were almost seriously injured.

And next time, Could you guys do a SuperHero vs SuperVillian episode? What is the point of having superheros if you don't have supervillians to counter? Smile

What if instead of using the grappling hook to climb, you attach an electromagnet that could be fired from a spring loaded gun, the electric could flow up the cable to the magnet, make the gun out of stong springs that could have tension pulled by a small crank on the side of the gun, even though you could only hook to metal you could make the magnet strong enough to hold a human.

Well saw the episode and as usual jamie did a great job or the amount of time and limited budget that the show must have but Adam. The whole grappling gun idea I thought should have say a grappling hook. And leave it to Adam to do a p_ss poor job I think he should have used several attachments from a hook tip to several penetrating heads but he should've sat down for a moment and thought of how concrete fasteners work. Such as flanges or "ribs" to help hold the heads into place. And why make the thing so huge once again poor planning and ever poorer execution. Reduce the size the heads maybe increase the explosive ie use a 32 or larger calber shell more penetration and also maybe testing the myth vertically instead of just horizontally. I mean if your gonna take the time to test it. Personally I think jamie could get a handle on this one. If Adam wasnt the plucky comic relief I'd say fire him.

But then you go and see them pull some stunts like Jamie did in the utility belt grappling hook. When he got to the end of the line (27 feet in the air) and realized he had no reverse, he cut the line with a knife. First off, I knew he would get hit in the nose when he cut the line, but I thought for sure he would cut through his safety line as well (about 6 inches from doing it), and fall the 27 feet. Could have been worse.

He was fine, it would take quite a few cuts to go through a climbing rope.

Pretty good points but while I was reading that the principle behind those rockets that are used for underground bunker busting came to mind or those projectiles that are used to circumvent reative armor. but then again who knows at least in the comic Bruce Wayne was a billionare with a corpeation to help research and fund all his cool "Bat toys" Makes you wonder really how much time or money Jamie and Adam are given Takes a sly fox to do a half way job while waiting for viewer mail and forum complaints to verify enough viewer interest to merit a new episode. Plus it helps with job security

what about some metal stake attached to a cable that's wound up, sorta like what adam had, but instead of a harpoon, use one of those air pressure cannons filled with nitrogen or something, and shoot the stake out into the wall. make it really sharp so it sticks in the wall, and make the cable strong enough to not let adam go thud on the ground.

If that doesn't work, shoot it into a building made out of clay.

I'm surprised this hasn't been brought up, but what if instead of trying to penetrate the extremely hard concrete, you just had some sort of super adhesive or something (or even just the grapling hook. what was the point of testing that at the beginning without using it with their climber thing?). If you could find something that either chemically bound with the wall or could be activated and or released after being shot with some sort of cannon, the whole rig could be technologically and spacially possible (though probably not economically).

Amen! That's what I was trying to say.

I do not know if an adhesive would work, however I cannot say that Myth was busted right away. There are other building sides that Adams device would have easily worked on. I also like to add that his device probably could have been engineered differently. I thought about using a gun to shoot a rod with the cable and hook, instead of a bullet, u have a long rod. The other option is a small rocket to shoot carry the cable and hook, it may even penetrate concrete.

Did Adam miss the day of physics class when they taught Newton's laws? The rim-fire works because the hammer provides a force vector that opposes the 22 shell. In the configuration Adam used, there was nothing opposing the shell and the projectile simply moved backward, absorbing exactly half of the kinetic energy. Either the projectile needs to be fired at much higher velocity (what about Grant's nitrogen pneumatic rig) or there needs to be a second charge to create an opposing force (for the rim-fire to "push against" - by the way, this is one of the principles used in bunker-buster technology). Conservation of momentum - not just a good idea - it's the law.

I really think Jamie's device was totally awesome! Adam's was cool too, and i think he tried his hardest on that one! Smile

This is just my take, but I don't think the guys prooved or busted a whole lot in this area. I say that because Batman (for example) trained from childhood, thru adolescence and into childhood and studied acrobatics, engineering and all like that there for years. While Adam and HJamie have a lot of training and intellectual experience, they aren't exactly physical specimens<G>! I'm just saying the only thing they proved is that they themselves can't do it.
PS - Carey is HOT in her superhero costume!

great special but just thought i would throw this out there. it is a commercial assender that is on the market now. the company is atttemping to sell it the navy seal and for other military applicaions. it is not small but it works and you can get one today.

In "Batman the animated series" Wayne did first use just a grappling hook and rope. It took him a long time to develop the devices he deploys today. Some of them may have come from the R and D department of Wayne Enterprises. In the old TV series the caped crusaders only used a batarang and line to climb buildings. You noticed in the first movie Batman's lines went up but he didn't used them coming down like the animated series. Like most comics, Batman and others use a top secret super strong cable similar to Marvel's adamantium which is why it is very difficult to replicate the stunts in the real world. Might as well try busting Jedi powers.

Greetings MythBusters, on my first post, and sorry our associates just missed meeting Grant Imahara at Dragon-Con yesterday 09/02/07!

1. You guys telecast a mistake about the winch motor Jamie used. He labeled it "6 hp," where it most likely was 0.6 hp at 30,000 rpm. True?

2. You then geared down by two, 7:1 tandem reducers for a total factor of 49:1, outputting 612 rpm (though Jamie said 750 rpm). In fact, if a Milwaukee right-angle drive was used at the end of the gearing assembly, that drive typically has a 2:1 ratio, yielding 306 rpm.

3. How much torque does your little motor put out at 30,000 rpm, and where did you find this little gem? Caltech's Applied Science Dept could use such a compact device, and if you PM e-mail, data would be used responsibly and in confidence.

4. That was nice in testing winch speed by first pulling Kari horizontally, with Jamie's 2" machined spool pulling her at 1.35 ft/sec, later clocked by Adam when Jamie ascended.

5. A couple years ago, our associates calced what Grant likely did. Starting with hoisting 350 lbs at 1 ft/sec, the average horsepower is:

350 lbs x 60 ft/min = 21,000 lb-ft/min
= 21,000/33,000 lb-ft/min = 0.64 horsepower

6. And torque:

Horsepower = (Torque in lb-ft x Rpm)/5252.

7. Our hunch is that once Grant(?) had done the math, you went out and asked what the smallest DC motor and associated gearing was that could produce X hp at 750 rpm, rather than hunt for something specific. True? And congratulations!!

8. We're with Jamie, in that had Adam used a .30, .32 or .38 caliber cartridge, and a barbed grapnel-end instead of a nail, the projectile would've lodged securely enough to hold his weight. So it was only Adam's particular array of components that was a bust. Better luck next time!

I love how, when the Mythbusters can't do something, that they assume nobody can.

Forgive me for saying this, but when it comes to scaling a building and thinking of a superhero who could do that, I do not automatically think of a couple of 40-year old men with bad facial hair and not-so-well-defined bodies. Batman is not real, but his character seems to be (as in, his character does not have fantastic, super-human powers). I think somebody mentioned this earlier, but Batman has trained his entire life to be both strong and nimble, and to understand what goes into any stunt he might do such as climbing a wall with a grappling hook.

For example, I can do kickflips on a skateboard. They took me years to learn, and I am still learning, and I still have trouble with them. If the myth were "Is it possible to do flip a skateboard about the Z-axis (depending on how you view it)," Adam would try it and fail. Jamie would build a rig which would fail. Grant would build a robot that couldn't do it. It takes a human body to be able to do it, and it takes skill and practice to be able to do it correctly. Just like how the person with experience could kickflip better than those without it (Adam and Jamie, for instance), the same can happen with scaling a wall with a grappling hook. There should be a desparity between those who have practiced and those who haven't.

By the way, the first time I got on a skateboard, I couldn't even balance myself. Watching Adam and Jamie flailing on their grappling lines reminded me of that.

Either practice something before you make your definitive statements, or find somebody who is an expert and knows how to do it (whatever it is you're doing).

I was reading my new WIRED magazine and they have a powered ascender in it. looks cool, but it was cool to see it made by Jamie

1. It is a GREAT pleasure to report - with the help of highly skilled engineers from diverse industries - that all basic components of a workable miniature Batman winch have been identified.

2. The newly specified components will work in engineering and building the winch, as well as be a bit smaller in diameter, and also only half as long as the MythBusters right-angle gearmotor unit. That said, we are deeply appreciative of MythBusters' work on this breakthrough, after two years of our own engineering efforts that could not outdo the PowerQuick. The MB achievement - over a matter of only weeks - did what not even a DARPA contract to the aerospace industry was able to accomplish in years!

3. Our engineered winch:
- 0.6 motor horsepower, equal to that of MythBusters.
- Greater output torque, enabling lifting and lowering 350 lbs.
- Full electronic braking.
- Both forward and reverse operation.
- One right-angle, geared speed reducer, replacing three of MB's reducers and gearing.
- Half the weight of the MB gearmotor unit.
- 12 Volts DC, rather than MB's 44 VDC.
- Larger and single, rechargeable battery unit for longer operation.
- Miniature motor controller, plus servo adjuster, a fraction of MB's size.

Keep up the good work, MB - sometimes proving the pros wrong, and inspiring us all.

I looked through the thread, and I didnt notice anyone that might have stated the answer to my question.

I was wondering if anyone knew the manufacturer of those in-line gear reductions or where I might be able to find them?

I work at a hydraulic servicing shop, and we have had multiple jobs where one of those units could of saved us a LOT of time. We've been trying to find someone who deals in sales of those for a little while now, I thought I might come on here and find out if anyone else might know.
