"Oil Strider" Device Mimics Water Strider Insects 39
LilaG writes "Who hasn't marveled at the ability of water bugs to skate along the surface of lakes and ponds? Now materials scientists in China have taken a cue from water striders and created a device that can coast along the surface between oil and water. The tricky part was figuring out how to make an oil-repelling surface that worked underwater. It came down to coating copper wires with copper oxide microstructures that look like flowers made up of nanopetals. Scientists think such coatings could enable robots that clean up oil spills, bug-proof car windshields, and ship hulls that don't build up barnacles."
If the Chinese can make this (Score:1)
then the Americans should be able to make a robot that walks on air

I mean, if the Chinese can create a robot that "walk", or "stride" on water, the American should be able to come up with something that "walk" or 'stride" on air.
Not "fly", but "walk" or "stride"
As for the "drone", the Chinese and the Russian already have their own versions of "drones"

Or may be, he could skate along the surface of water too, and finds nothing marvelous about it. You never know who you talk to, on the Internet.

It'll still reject the oil, but the new thing is that this thing won't sink in oil instantly if a drop of water gets on it.

In oil spills, the oil floats on top of the wate, not the other way around. How can this help clean up oil spills?
If you read the summary, you'd learn that these things stride on the border between the oil and water, not between the oil and air - they're in the perfect place to clean up the oil.
If you clicked on the link, you could have even just looked at the picture [acs.org]. Then you wouldn't have had to read anything. Slashdot Posters: Lowering Expectations Daily.

And the picture clearly shows that the thing walks on an oil water air construct, where the oil is at the bottom, hence your parents question :D

I know it is not for the faint of heart but a quote from the article below means for the test they used an oil that is denser than water, so that means it's below the water/air barrier.
To test the surfaceâ(TM)s ability to repel oil, Wangâ(TM)s team placed the wires underwater and added droplets of 1,2-dichloroethane, an oil that is denser than water, to their surfaces.

Yeah yeah how great for humani..
bug-proof car windshields
Oh glorious age of science!
I know I'm a terrible person.. but as someone who does a fair bit of highway driving.. I really hope they roll that one out. While they are at it.. paint up my hood and bumper too (much harder to clean).

What about something like Rain X windshield wash? It's basically a waxy coating that lets stuff slide off it so the water tends to form droplets instead of sheeting.
Again, wouldn't a good coat of wax help here? Stuff might stick to the wax, but it should clean off easier.
