This does not seem to be Rearden metal, but it does seem to be really neat. I recall a recent paint product that was markedly hydrophobic - Interestingly enough, hydrophobia requires a really Rough surface on the nano scale, not a smooth surface.

Uh. jbrenner. Mind if I log into your class too?

to do this process on steel large enough for my boat 28 feet would be monumental for Ellison's size boat we are years away unfortunately.

It would seem to me that any pattern that had to be laser etched on a surface would only be super hydrophobic as long as that surface can maintain that shape.

With that being said, it seems to me that the minor scoring that occurs via flight would quickly obliterate this pattern unless of course the metal were so how able to completely withstand all forms of weathering.

That has been done, albeit not by me. See

i owned a dutch built steel hull sail boat and each spring it needed to get 3 coats of zinc paint before the copper base bottom paint. having a hull made with this composition of steel would have been good on two counts, one against corrosion and two the hull would probably more more swiftly through the water since it is not attaching to the steel.
now all they have to do is commercialize the process. also it can be used to replace all of those bridges around the country..

Looking through your 2012 ppt on there and your background... I like the mention of silver anti-infection coatings. Any chance on getting silver officially approved by the FDA as an antibiotic, maybe making a "nanocomposite" material out of it, claiming you made a new nanostructure out of particulate silver solutions, and it showed highly antibacterial properties?

Then from there, once approved, you could just say "oh and regular silver nanoparticles (not ions) work just as well". Think of the lives that could be saved (and the new bacteria-resistant superbugs that wouldn't be bred).

Really cool. I can see Larry Ellison's next racing yacht hull made with this technique...

I'd like to see heavy rain hit a sheet of that metal.

Looks pretty cool. I wonder though how durable the surface is, how much pressure/abrasion it would take to damage the surface and remove the hydrophobic properties. A little damage to the surface over a small enough area (I don't know, a millimeter scratch? not sure) could possibly make it so that that part of the surface isn't hydrophobic anymore.

Rearden Metal is supposed to be a part-substitutional alloy of iron and copper, with carbon added for extra strength. I'd like to see someone actually produce such an alloy.

But what I did see here, is very impressive, for the appropriate applications.

I really appreciate how you keep the gulch humming. I also really appreciate the fancy stuff :)

sure thing

thank you so much, professor

thanks jbaker

it's not letting us in :(

j, this is what I have db for. he's downloading...

Online - yes and no.
Yes, you can download the course materials over the web. No, it really isn't an online course for credit. Go to

It is a three hour night class meeting tonight.
Last week we met twice, but that will be the only time that applies. One of my students does record some of my presentations, although the last one was low on the volume side.

As for the nanotechnology lab class, you can see what we do online, but lab classes are hard to do over the Internet. If you send me an e-mail address offline, I can catch you up pretty quickly. The superhydrophobicity part of the course is in about 2 months under Bioinspired Materials. Think of the lotus leaf.

That is slick! "Yeah. Their uses are almost endless." Hank Rearden

is it online? have I missed any classes? :) I'm glad you're in my gulch

If you want to learn about how to make superhydrophobic surfaces like that, you should enroll in my nanotechnology lecture or lab courses this semester.

Rearden metal aarrrggghhh!
