Julia Greer talks 3D Architechted Nano Metamaterials

Solve for X: People accelerating progress on technology moonshots.

Materials Engineering has come a long way since my student days in Cambridge (more than 30 yrs ago) trying to make strong stiff, fibres from polyethylene! Very impressive and extremely inspiring lecture. Makes me feel like going back to University. Thank you Julia Greer.

[@Skargar]

Wouldn't the equivalent material to 1.8 t with 99.9 % air weight 1.8 kg instead of 1.8 g? Or is there something quadratic?

[@SeanLumly]

The opportunities for making composite materials from these materials is extremely exciting. I hope that near-future research explore these opportunities!

[@oker59]

This is just fractals with nanotechnology; I'm surprised this hasn't been thought of before. I'm guessing one can go much further with this once nanotechnology really gets going. But, this is exciting to see this ability pre-full nanotech era.

[@roidroid]

oh it's been _thought of_ plenty of times, the real innovation here is that they finally figured out a successful manufacturing process for it. It's now real.

[@oker59]

Feynman/Drexler nanotech may finally be in the making; just the last few weeks including two days ago shows they can now start to make nanosystems that can assemble nanoparticles arbitrarily.

You could build spaceships the size of cars, fit them out with some sort of plasma engines and they would be able to break orbit, I bet.

[@bashful228]

Tesla batteries are unsafe? Safer than a petroleum fuel tank by a few factors of ten I would think.

[@ShaDoWworldshadow]

yeah thought that was a bit of a BS statement as well.
