Ahh.. the old helium thread ..I haven't seen it in a while.

Helium simply does not have enough "lifting" power to make much of a difference in normal LEI kites. Do a search on this forum and you will find old discussions on this topic. It has even been tried by those who cannot do the arithmetic to figure it out ..always without success.

:wink:

Filling your kite with helium will make it like 2 grams lighter, so there is no point.

Easy as that.

:o
Holy cow..!
In my mountainbikedays, there was this engineerguy with to much time for himself that made an investegation of the brilliant idea of of using helium in his tires... to..., have no fckuing idea really... what he wanted to do... fly uphilll or something?
Basically heliummolecules(?) are so small that they will escape anything, (they'll evaporate trough your bladders...) But sure, it will take some time, and as long as you have a kiteparkinghouse on your beach... go ahead. When you get bored, inhale some of the gas and do the "Donald Duck".

(Me myself have used it to check leaks in highquality tubing for other gases.)

Dude,

1. Gases don't evaporate.
2. There's no appreciable difference in the size of the molecule from a materials standpoint - balloons, like bladders, hold helium, hydrogen, and air, all well. Though helium will escape faster, it won't matter for a session of kiting.
3. Lots of cyclists use helium to save weight, as a few grams matters to them in, say, the Tour de France
4. If your average kite bladder holds about 100L? (I have no idea), you would save maybe a few hundred grams max.

If we all remember our chemistry.. He is about 4 g/M and air is around 32 g/M and a mole at STP is 22.4L.

DUDE... :D

I'm sure that you are right..

I just suggested to get a warehouse on the beach to keep the kites inflated, or to bring the tube to the party... :cool2:

I have basically espaced out of engineering, but sure could always call one of the remaining "heliumsuckers" if you want..

Basically i'm filling my kites with air and good humor...

Main problem is that the helium is compressed. Once it is compressed it is more dense making it heavier. Second problem is that the Helium molecules are very small and they seep through the bladder.

Hai,

Yes, but cyclists do it because of the high pressure in the tires and in order to avoid water vapor to condense and become liquid.

Yes, and with ~ 200 l (let's say 10 Mol) in a large kite it will be 32-4 = 28 grams * 10 = 280 grams of weight.
Great sensation!
