##### If I Replaced The Glass In My Windows With Diamond, How strong Would They Be ?

Dearest Proletariat,

See my house ?..

[attachment=16899]
My House

Nice eh ?

Having an extension built next Tuesday !

I have a dilemma !..This morning an extremely rare-last-of-it's-kind-ever butterfly flew into one of my windows and this upset me greatly !!...It smudged my window somewhat !!..I'm sure ewe can imagine how disturbing this was for me.....despite the butterfly being fine I had to catch if it and dispose of it down the toilet because I could not risk this happening again !...I just know ewe would do the same !

It got me thinking though, say a bigger butterfly flew into my window...it could break it yes ?...so..I've decided to exchange every pane for solid diamond because I've been told that diamond is like well hard. ...My windows are double glazed and each pane is about 10mm thick 7ft by 4 feet wide !

Will they withstand the force of a butterfly ?....assuming the frame withstands all pressures what kind of thing could smash my windows ?..a brick thrown very hard ?...a marshmallow ?... a bullet ?.....speeding car ?

whajafink ?

Hugs and shmishes

mwah mwah mwah

Not strong enough to keep the Thieves out!!!!!!!!!!!!

Wikipedia has a note on the Toughness of diamond.  Like many hard substances, diamond is somewhat brittle, and has fracture planes.  So, striking a large diamond with a hammer, and  you end up with hundreds of little diamonds.

According to Wikipedia, Diamond has a "toughness" of 2 MPa$$\sqrt{m}$$  (in megapascals, and m is the mass).   Soda lime glass, on the other hand is somewhat weaker at 0.7 to 0.8 MPa$$\sqrt{m}$$.  I'm not seeing the same rating for tempered glass, which is strong depending on the plane of impact.

Hmmm...
Aluminium oxynitride or AlON is considered to be one tough type of glass (and almost as expensive as your diamond glass).  However, it is also listed as having a toughness of 2 MPa$$\sqrt{m}$$.

Synthetic sapphire also has a toughness about 2 MPa$$\sqrt{m}$$.

So, I guess diamond ranks up high with some of the the other tough transparent media that we can produce, but not really any better than some of the others (unless you also consider scratch resistance).

If you want something that is tough, alternate layers of plastic and glass is often used - with a combination of hard and soft: http://en.wikipedia.org/wiki/Bulletproof_glass#Recent_advances

This composite material is also much safer than glass if peopleare likely to fall against it, since it does not shatter into sharp pieces.

Your electricity bill would not appreciate diamond windows - they are one of the most thermally conductive materials known.
Thieves would like a diamond window - shattering it into smaller pieces would make it easier to take away.

hmmmm !!..Thanks Clifford !....perhaps I've been a tad ostentatious and should have gone for some of Scottys transparent aluminium

Thanks evan_au....gosh..I had no idea about the thermal conductivity of diamond *Cancels order for diamond roof insulation*

I'd be rather careful when choosing a window cleaner.
If brains were made of dynamite, I wouldn't have enough to blow my nose.
