HHO as fuel?

[budabob07]

Would HHO work as a fuel in a standard PVC combustion gun? I'm guessing that the force of the explosion would shatter the PVC. Has anyone tried this?

Use the search function. This topic has been beaten to death.

And don't posting anything relating to "HHO", it makes you look like an idiot. Use the proper name of just hydrogen (H₂) plus 1/2 O₂.

LOL.. How about 2 H2 and one O2? 1/2 of an O2 is rare as it combines with almost anything even another O2 to become ozone. You can find 1/2 of an O2 in an ozone generator and in a fire, but it doesn't last long.

if it work for a ghetto i dont see why it wont work in a good quality pvc cannon

Thank you Crna

I strongly advise not to use it in a PVC cannon. The gas burns very fast (above the SOS in air).
I would think the PVC cannon would fail.

This is a nicer vid however

inonickname is very correct, this topic has been beaten to death, and the general consensus is that it has a lower energy yield for projectile propulsion for a given volume at atmospheric pressure than does an oxygen/propane mix.

So you are comfortable with "HHO"?

To a chemist a molecular formula is assumed to apply to a sample, not to a single molecule. Since a small sample of any molecule contains milliontrillions of atoms the fraction is not a big deal. 1/2O₂ is perfectly OK, though usually the fraction would be removed; 2H₂ + O₂.
But 47.2156H₂ + 23.6078O₂ is OK to.

Regardless, the point is that HHO is just plain stupid, and inaccurate, since it implies two monoatomic hydrogens and a monoatomic oxygen, or more accruately, it describes water, which isn't a fuel at all.

I must concur with jimmy101, HHO is an uneducated term used by those who install such things in cars.

In STP it is generally 2H₂ + O₂. It's a ratio of 2:1 H₂.

I get slight rages when chemistry terms are abused, HHO being the main one.

I laugh when others are abused. Here is a classic;

Ah the big drama around that omnipresent poison DHMO. That was nearly banned out here (Aus). Possibly the best troll in existance, even better than the Oprah troll.
