Hawt So, scientists have created a metal that is so hydrophobic that water bounces off it

[thintoast]

layer the outside of the future space transportation devices with this stuff and you'll never have to worry about water getting into a small crack and freezing to make it bigger.

Theres water in space?

its thintoast. Thintoast doesnt science.

What's the point

That plane that recently crashed. The suspected that it was due to ice buildup (at one point, no idea if that still stands). That problem goes away.

not to mention it would've just bounced off the ocean and back into the air.

Interesting, making a surface that hydrophobic means you have to make it chemically non-polar to prevent ionic attraction between the water and surface, and have an extremely smooth surface (little surface area) to minimize van der Waals adhesion. And they seem to achieve this by blasting it with a laser - creating god knows what chemical mess on the surface, which is likely highly polar... and definitely increasing the surface area.

The whole thing seems ass backwards... I plasma etch stuff at work to make it hydrophilic.

You are very smart.

That's legit praise, not being sarcastic.

Would it affect water friction?

Like the bottom of a boat on a lake, etc.

Just saying, put a jet engine on a fishing boat and watch it break the sound barrier.

Should've just used rainx, amirite?

There's water in the atmosphere on the way to space. I bet it all blows off though by the time they get to the point where the moisture will freeze.

In space (where kPa is nearly 0), any water will boil (according to PV=nRT) away, but will then desublimate after some diffusion to form many tiny ice crystals.

I saw a NASA PR person do it at the NASA booth at the balloon fiesta this year.

Nah, I just work with this stuff on a daily basis so I'm familiar with it.

Ask me to do something like behave in public and I'm useless.

 

[APRIL]

Behave in public.

 

[Duke]

Behave in public.

something you are also useless at

 

[Josh]

Needs more hydrophallic

 

[fly]

hydrophallic ftw

 

[thintoast]

Hydrophobic? Is that like Homophobic?

 

[Mr. Argumentor]

Hydrophobic? Is that like Homophobic?

Exactly like it, just with a different root word.

Hydrophilic means it attracts water (loves water, is closer to the original language, greek I think?)
Homophilic means it attracts gays, fly is homophilic
