Heavy-water snow

post #1 of 18
Thread Starter 
My post about "Heroes of Telemark" made me think of something else - Would it feel different to ski in snow made with heavy water? I think I have to get out of the house.

heavy water is used in nuclear power plants--i doubt you would want to ski in it

heavy water

Heavy water is not radioactive. My days of HS physics are way behind me, but I think that it is made with an isotope of either oxygen or hydrogen that has one or more extra neutrons, giving it more mass than "regular" water. Heavy water has some role in modulating nuclear fission, although I don't think it is used for that today. I don't think we would notice the difference if we skied on snow made from heavy water, we woud only notice the differnce if we paid for it!!!

Heavy water is chemically the same as regular (light) water, but with the two hydrogen atoms (as in H2O) replaced with deuterium atoms (hence the symbol D2O). Deuterium is an isotope of hydrogen; it has one extra neutron. Thus the deutrium atom consists of one proton and one neutron in the atomic nucleus and one orbiting electron. It is the extra neutron that makes heavy water "heavy", about 10% heavier in fact.

wonder if there is a change in the physical properties (boiling/melting point elevation)....any chemistry people out there?? You could make some solid spring-proof base with ditritium oxide !!: ...that is...if you could afford to produce that much of it in the first place............


edit: brain fart........

bpt/mpt delta only applies to colligative properties........my chemistry is corrupted!!

If you could ski on snow made from heavy water you would have infinite amout of deep dry powder because Heavy water is used for FUSION power which has the potential for unlimited power. Unlimited power means unlimited deep powder . Get it

Back to your regular scheduled program.

Didn't the space ship from "Lost in Space" run on duetronium. Seemed they were always looking for it.

I think the "powder" we get at Mt. Baker is often made of heavy water.

What a cool question -- doesn't seem like anyone here really has a solid answer for you.

Based on what people have said and the links posted, it seems logical that heavy water snow would work for skiing the same as regular snow.

It'd be like skiing on manmade snow.....

You're not that far off base. I think this is what you are loking for:

Code:
 H20D20
Molec. Wt.1820
Melting Pt.0 C3.82 C
Boiling Pt.100 C101.42 C
Viscosity1.0051.250 centipoise
Heavy water which is not 100% hydrogen or 100% deuterium will actually contain a mixture of H-O-H, H-O-D, and D-O-D molecules. Thus, will melt or boil at a temperature between the two extreme cases given above.

Soooo … from the looks of it, if you had seriously deep pockets and could cover a mountain in frozen D2O, the snow would stay frozen to significantly higher temperatures.

Before you start dreaming about doing this, the price of pure D2O is about $400 - $600 per liter (http://www.isotope.com/cil/products/...m?prod_id=5701 ) (in small quantities). : : : :

To get back to the original question about how it would feel to ski on frozen D2O, I think the major differences that you would feel result from the surprisingly large (~ 25%) difference in viscosity. Spring skiing on D2O mountain would bring a new understanding of just how thick and heavy snow can be.

HTH,

If one had unlimited powder made from heavy water, one could conclude that then the skier would have the effect of being lighter and wouldn't require the behemoth boards being ridden today and skinny skis would rule the slopes again spawing a whole new heavy snow ski trade market.

When the first ski resort outside of earth opens let me know about skiing on somehting besides H2O. You'll be able to tell then; you can't now. It really would be fun to ski on another planet...

With the price of tickets at Stratton, I think they might be able to afford it now .

Tom,

I like the precautions for storage of Deuterium Oxide, "Store at room temperature away from light and moisture."

At least it doesn't appear to be as dangerous as Dihydrogen Monoxide.

heh...now that's funny. I guess there's a website for everything.

I never touch the stuff myself. Fish swim in it. [/WCFields]

Tom, I think you got the quote slightly wrong. "Fish fornicate in it." Or words to that effect. :
