    From the standpoint of somebody who likes to service and fix things if a hinge or other part on my vice grips goes bad, I can replace the pin, or even make a new one in my shop. If a hinge breaks on his model the whole thing is trash. I don’t know that I like that in emergency situations. You know, like Apollo 13.

    Wow, this is so cool. One question for the two titanium "hinges", especially the first one that's supposed to be used on solar panels. Since it's probably going to be in one of the compressed positions for extended periods of time, isn't there increased risk of the material weakening/failing in the point of greatest stress?

    I was able to figure out the elephant rather quickly. Unfortunately, my reverse engineering is as good as my creativity is bad. As for his work, this guy is absolutely amazing! I would've figured bendy stuff would just fail too quickly to ever be effective in the long run. Challenging preconceived notions like that are how humanity can keep advancing.

    This is super neat and all, but you didn't address at all the one burning question - fatigue! How the heck do these applications interact with material fatigue!? I mean presumably we all know how to bend spoons, or failing that, coat hangars - I'm sure he has answers to all of our burning questions about the various applications - ahhhh now I'm going to have to check the literature on this, though I'm guessing more viewers don't have access to journals or know to look there - so cmon man don't leave us hanging!

    Uh this was more like a huge advertising. It didn't address any disadvantages. What about repairing something? You can't replace a screw. But more important: What about aging? Plastic can get recalcitrant (ist this the right word?) and get micro-cracks. Yes they said they did 1 mio cycles with one element but was this verified by a neutral third party? Also you can't just randomly scale an element since it's behavior will change. So this might be interesting for some cases but the video presented it as the best thing for every case and without any scientific scepticism. But as a scientist you shouldn't be fanboying something so easily. About the satellite thrusters: This whole element was superfluous. There were two motors. You can already archive the movement with just two motors, no need for flexible parts. Actually they just provide another potential point of failure. Especially in space you want to avoid that. That's why they prefer a second thruster (also this provides redundancy). Also space is pretty bad for plastics. So this example was pretty bizarre (to say it mildly).

    > Repairing You have to replace the entire part. Availability apparently not an issue because these things can be 3D-printed. The design for the flatter pieces can be easily printed without any extra cutting or filing done afterwards like you would normally with many 3D-printed designs or even for injection molds. Manufacturing at a large scale is also shown to be much simpler - since the pieces aren't made of smaller pieces. The thruster piece seems very complex though. > Aging Bending lasts longer than moving/sliding parts. Also, a single piece, glue, or a weld will always last longer than something that has nails/bolts/screws/rivets. You can't avoid non-moveable parts from actually moving - they will always bend, and they will slide at the seams. Also, it showed that the material doesn't have to be plastic. They showed a single piece of titanium bending with 90 degrees range of motion. > Testing by neutral third party I would suppose that the 3rd party would be review board, or their clients (e.g. NASA). I don't think it really matters at this point - a question was asked, and they answered that their stress tests showed promising results. It didn't sound like sales talk as you're suggesting. > Randomly scale What are you talking about? It showed that the items work the exact same way at a microscopic scale. > Satellite thrusters Again, the parts don't have to be made of plastic for this particular application. Using bendy parts and having redundant thrusters is not mutually exclusive, but I'd reckon that satellite designers would want to minimize the amount of parts as much as possible. Every extra gram you shoot up into space is luxurious. The 3D animation showed two motors, so it wasn't about the motors but rather the "hinge" where the thruster would float about. Normally, you're gonna have some sliding parts, like a wheel and axle. If you watch the video again, the design was meant to be accommodating for electrical lines and fuel lines, so on top of allowing to have less weight than a conventional design, it's also easier to design around it; it's not superfluous.

  47. Abelardo Mieres

    Abelardo Mieres3 hours ago

    The prototypes are made of plastic, the actual final parts can be made of metal (they showed some made of titanium). Making the thrusters directionable actually adds a component of redundancy. The idea would be that if a thruster breaks down, the remaining can be redirected to compensate. He is excited about the technology and its potential why can''t he be? Like him, I find it fascinating and even beautiful.
