OK Trekkies. Scotty's going to get his cloaking device to outwit the nitwit Romulans....see:http://arxiv.org/PS_cache/arxiv/pdf/0904/0904.3508v1.pdf

Pulls out phaser.

Vaporizes trinitee.

They reference the work discussed in this thread: Metamaterials and cloaking (http://www.bautforum.com/space-astronomy-questions-answers/48258-metamaterials-cloaking.html)
They also are working in the optical range.
It's a good link with the details, but I would like to know how it differs from the other work.

Otherwise, It would look to me like just another invisibility thread which are starting to sound like noise to me.

Except when it's Trekkists.

Let me see if I can change the focus of this thread from the others on http://www.bautforum.com/science-technology/45566-invisibility-2.html --at least a bit.

What I would like to know is if you can make something invisible to heat or at least the infrared.

As you know the space shuttle is rather unlike most other aircraft in that its upkeep has more in common with THIS OLD HOUSE, than with anything else. Bob Villa could spackle the orbiter up with tools he probably used quite often. Sadly shuttle tiles don't do well in rain.

So if a tough coating of borazon (which is already resistant to high temps) http://en.wikipedia.org/wiki/Borazon --were to be nanomilled so as to be invisible to infrared...then heat would pass through to tiles underneath which would absorb the heat. The outer covering means that rain has a surface to run off without ruining tiles, that might resemble these structures only done in such a way to absorb heat and not sound:http://en.wikipedia.org/wiki/Anechoic_chamber or the tiles used by subs.

Ceramic tiles would be underneath a borazon skin with infra-invisible matrix within the substance that itself would under a clear coating that could be sprayed on.

Then too, there is more than just thermal insults when an object re-enters the atmosphere--and different ways to transmit heat than light.

Any thoughts?
