Stronger than steel

- What's 10,000x thinner than a human hair but 100x stronger than steel? Ashely Kaiser, a graduating PhD student in the department of materials science and engineering, worked with MIT's necstlab and NASA to leverage carbon nanotubes in designing stronger, tougher, and lighter materials for future space vehicles and habitats.
You are 110% correct on perspective and scale! I haven’t thought about the Grand Canyon and composites also!
At one point I thought of the idea of using bridge cables, like the Golden Gate bridge cable, but as thread on a composite. Except each 5 to 10 foot thick cable would be composed of carbon nanotubes with graphene resin. Anything else between the cables/thread could be lesser quality Nanotubes, chopped carbon fiber, graphene resin (forged)
I thought of making an O’Neill cylinder out of carbon nanotubes and graphene, like weaving baskets. And with different weaves you can put different functionality into everything
We need to make a O’Neil Cylinders. And we need to make them with carbon nanotubes and graphene.
Right now the only way to utilize either of those is in yarns and as additives in concrete/cement.
I thought of Making an O’Neill Cylinder with a “loose” carbon nanotube basket (like a cross cut design) at least as wide as a person, and up to 10 feet in diameter (providing torsion and tensional strength, along with compression), stainless steel footings could terminate into huge tiles (going through the depth of the walls/floors) along with girders and meshes of different sizes filling in any spaces.
The filler material can be concrete, but I thought of essentially a type of graphene plasticized medium would be better, that way it’s stronger than steel, and if you rotate the cylinder with Station sized flywheels/gyroscopes, you can move it without thrusters while having better energy storage than lithium. After that, all you need is a fission or fusion reactor to power it forward.
Having a basket made out of carbon nanotubes gives it added strength, and allows you to essentially pre-wire The entire place, along with embedding graphene super capacitors.
-The entire cylinder would be able to store power, along with the huge fly wheels that also move it in space.
Doing anything else other than making cylinders is a complete waste of time and resources. For the cost of robotic missions, we could literally have a stable outpost on Mars and we could swap out crews back-and-forth easily. A “mothership” if you will.
On top of that, you could use the interior or the exterior to mechanically or electrically launch space craft.
If you had two O’Neill cylinders that were 40,000 feet in diameter and 300,000 feet in length, you could launch a “Seed Cylinder” mechanically/electrically. having to move a cylinder with that kind of tonnage would be incredibly hard. The best way is using mechanical means, followed by electrical means. Saving you rocket fuel.
It’s not quite a railgun gun, but you get the idea
Look at those crosscut plastic wire handbags, and nestled them inside each other with metal bolts, and you get the idea.
That way, most of an O’Neill cylinder would be able to store power, and it would be equal parts carbon nanotube, graphene, and stainless steel. It would be superbly strong, and store incredible amounts of power throughout it
Would this ever be able to be used for something such as 3D printing? I feel like that would be insane with what you could make if that was possible, you could make anything!
If 9²⁻ˣ = 3, what is the value of x?
Say to people Einstein is back.
How cool to be working in such advanced labs, in hallways that have not changed since I was at the Tute in the early 70s. An aside, how did you get started in Rings?
My, that was my old lab in bldg 33, 2nd floor, and before that, among others, Gary Klein of Klein bicycles fame.

This new material might could be used in a large percentage of passenger aircraft frames and wings? It could make jetliners much safer and fuel efficient. Also the material might could be used in solid state EV batteries?
Or maybe even hydrogen fuel cells!
@@Iquey , yes, indeed.
Awesome, Dr. Kaiser. Thank you.
Not for only nano tubes of carbon also I promise MIT I will definitely stronger than me myself and do my best for what I want to live

One property of nanotubes is that they're really, really strong. Tensile strength is a measure of the amount of force an object can withstand without tearing apart. The tensile strength of carbon nanotubes is approximately 100 times greater than that of steel of the same diameter. 🤫😄
Congratulations on 2DPA-1. I think it’s one of the largest breakthroughs of the century.
Impressive!
Has anyone made a Strong, Lightweight Electric Motor using carbon nanotubes and graphene carbon composites?
What do you thinking of using two o Neil cylinders connected to each other like a Huge simple transmission, launching a Third one forward, saving you fuel on the one you are launching?
Can this be made to make prosthetic ribs?
let's povoate the space around
Very Cool 😎
Stuff , stuff , stuff 😄 nice
Cool

3/2 :)
Shut up spammer.
Well that's cool.
