| Yeah ill be a senior this coming year. I took a chem class but i was in the same class as modder and we mostly talked about spudguns, he knows a helluva lot more about chem than i do. |

| Ah, high school chem classes suck, I thought I knew everything, then I got into my college class. I learned so much more. But anyhow, the gasses will stay homogeneously mixed so long as you stay away from the liquefaction pressure (the pressure that causes the gasses to turn liquid). |

| Ok well, thanks for the newfound knowledge about gasses. On the plus side playing with liquid N2 was quite fun! |

All you lucky people and your high school chem classes. My school doesn't offer chem classes until 11th grade (I am in 10th grade), and they have so few qualified teachers, they have to alternate between chem and physics each year, meaning I won't be able to take a chem class until 12th grade.  |

Haha, I'll admit, I did have fun. We did the liquid N2 thing, we set up an apparatus that was a tube from the natural gas outlet attatched to a funnel, we dipped it in bubble solution and blew bubbles with natural gas... then lit them, bwahaha. We also went outside with a bucket of water, a bar of sodium, and a spoon. Cut the sodium with the spoon and throw chunks into the water, awesome fun. |

Yea, well, they won't let high school chem teachers have that, at least that's what he told us. Also, we were using an old metal bucket to hold the water, if we were to use cesium, we would have to replenish the water after every reaction, and the inherent violence of the explosion could have rendered the bucket into shrapnel which could be quite dangerous. |

I really wanted to take chem and thats why I am currently. We too don't get offered chem till '5th Form' which is '11th grade' I believe. But I am bored sh|tless of it, I didnt pay attention last year so im struggling through this year not knowing anything. And most lessons are theories then when we do practicals its like mixing HCL with Zn and see what happens Not much I tell you lol
Edit: My bad  didn't actually read the topic title, just thought it was a topic about chemistry

I quote jimmy101:

Some people just have no concept of how a gas behaves. "Make sure the gases don't settle out" is of course, blatantly idiotic. 2 gases, injected into one container will mix at a fairly slow rate, until they are completely homogeneous. Neither gas will "settle out".
The concept of a larger tank of premixed air/fuel has been done before, check out noname's generation 1 hybrid in the showcase section. |
yeah but if it is under pressure won't the propane liquefy and then settle |

At 4% or so propane, that would be a very, very high pressure.
In gas systems, the pressure is split in equal proportion to the contents, so 4% C3H8 at 100psi would only apply 4psi of force to the propane itself. (Pretty damn far from the liquification point.)
You just gotta love gasses... |

We're all here to learn and share, right?
Anyway, thanks for your help guys. It seems like this is more feasible than I thought, so expect a hybrid out of me soon! |

Bah, cookbooks my friend, you need cookbooks!
Indeed, this is a place for learning... perhaps we should be accredited? |

This is mostly the fact that i forgot to think about my first go around, i figured that it would be a 50/50 mix(hybrid newbie here)
