Would Graphene be the next kite foil material ?!

It is the thinnest material ever made. You would need to stack three million graphene sheets on top of each other to get a pile one milimetre high. It is also the strongest substance known to mankind — 200 times stronger than steel and several times tougher than diamond.

A sheet of graphene as thin as clingfilm could hold the weight of an elephant. In fact, according to one calculation, an elephant would need to balance precariously on the end of a pencil to break through that same sheet.

Despite its strength, it is extremely flexible and can be stretched by 20 per cent without any damage.

It is made from abundantly found "Graphite" and formed into a honeycomb nano structure, and the base material is relatively cheap...

Can you control the stretch and does it return or stay stretched. Sounds exciting. A

Here is a link

"Strength applications. One atom thick sheet is not that tough, but when graphene sheets are incorporated into composites, you could come up with a material that's many times stronger than Kevlar." Dr. S.S. Verna

"It is almost completely transparent, yet so dense that not even helium (the smallest gas atom) can pass through it." Dr. S.S. Verna

HEY READ THIS ARTICLE!!

Wow, one atom thick, the best conductor of electricity and heat on the planet. it may replace indium tin oxide - transparent stuff that is on touch screens as it conducts electricity but expensive and it cracks - TV's will be paper thin, mobiles that can be folded up...and it is 200 times stronger than steel and several times stronger than diamond. And it is just that grey stuff we use in our pencils (hence why thin layers of graphite peel off when using it).

And its completely transparent!

Man the kites will be light as paper and unbreakable! Cheers for that, awesome read.

I'm not sure I'd want to be waving 12m² of the worlds most effective super-conductor 24 metres above my head whilst gliding over that other highly efficient conducting medium.....water

Still reckon it might arc if hit why you are in the air.

There goes the instant turning response. You pull the bar, 10 seconds later it turns.

This is very exciting indeed. Pity it will take too long for the applications to come through to kitesurfing. R&D still and then red tape will see this filter through us perhaps around 2020 at best.

Well, it's a start and very promising.

Love science, always more ways to skin a cat :)

Hmmmm, so how does it go with hydrogen, you know, the one smaller than the smallest?

Awesome - no bladders required either.
Might just make the cheapest kite ever.

But what about all the beginners? They would have nothing to look up at
And how would you ever find it if you unhooked & dropped it
Sounds like a problem to me.

Damn. I'm getting flashbacks to Cubenfibre. The supermaterial that Best was marketing before they found it... disintegrated.
