nitrous contains more oxygen than air
Compared to liquid oxygen though, they should be pretty similar in oxygen content. The the reason nitrous oxide is used rather than liquid oxygen is that when NO2 is used as an oxidiser, the nitrogen atom that is evolved releases a large burst of energy when it forms N2. Ie:
2 N02 => N2 + 2O2 + energy.
The following is a link explaining the energy difference between an N-O bond and an N-N bond. Simple nitrogen chemistry
It seems I forgot to mention in my other post that it has been my observation that higher revving engines have shorter strokes. This basically means the frictional force has less distance to work over. This reduction in work can be expressed as energy and as such, you will loose less energy to friction per stroke. Increasing the angular velocity and reducing the stroke may cancel each other out if carefully balanced.
I would have thought that producing the peak torque (for a given throttle setting) would producte the highest efficiency. Given that there will be a set charge of energy per inlet stroke (assuming a perfect stoichiometric mix) and assuming the following axioms:
efficency = usable energy out / energy in
usable energy out = force * storke (constant distance)
force = torque / crank size (constant radius)
energy in = roughly constant
then:
efficnency = constant * torque
where the constant is roughly equal to stroke length over crank radius times input energy.
Since torque is variant on angular velocity (RPMs), then wouldnt it be best to use the angular velocity that produces peak torque to gain peak efficnency?
I'm not sure if you are American or not, but in the Queens English practice is a noun. Practise is the verb which means to train to improve ones skill.
It just seems kind of funny that someone who is advising somoeone else on their English may not have it right either. That being said, I'm sure there are more than one or two mistakes in this post.:)

Personally, I don't feel that men and women have different brains. I'd rather think that it was social conditioning, but there is a valid reason for this post. My problem is that the following statements yours make little sense to me when put together.
It is a fact that men and women's brains have evolved differently over the ages.
And:
We simply do not know enough about the brain to speculate at this point whether on average one brain is more optimized to certain types of tasks than another, although evidence would support this (women's communications centres are larger, men's spatial-relationship centres are larger).
If we dont know enough about the layout, how can we claim the male and female layout is different as fact? Anyway...
What is so different between two people, one having two X chromosones and the other having one X and one Y? Does anyone know if there are genes on the Y chromosome that cause such an evolutionary divergence? I have been lead to believe through my reading on human development that this is not the case.
How can we claim that our habits and worldly likes are genetically controlled when (as far as I know) a baby learns to smile? Some stuff must be hardwired, like breating, heart control and the like... But I can't see how our preferences in what we like to do can be so simple.
Of course, I am an engineer. I am not a biologist, phycologist, brain surgeon or a good speller.:)
About half way through that level, you'll find *something* walking about. If you want to see something really freaky you should follow it and watch what it does at the ends of its patrol route.
Its like being in the movie "The House on Haunted Hill", and that is scary enough.
As an interesting side note, this far I have found Doom 3 quite predictible and really not all that scary. The level called the "Cradle" in Thief 3: Deadly Shadows pales anything I've yet seen in Doom 3 for scaryness.
In my experience, 80V is quite tolarable. An unloaded arc welder will produce this kind of voltage, and when loaded it will drop to roughly 20V.
I've electrocuted myself in many different ways, I have taken the full brunt of New Zealands 240V household mains potential, and I have stopped a lawn mower engine by grabbing the spark plug HT lead.:)
I will take no risks when dealing with conductors and car batteries however.
My fathers friend almost lost an eye when he didn't connect the batteries correctly while jump starting a car. The reason for this was that lead shrapnel splinters from the batteries embedded themselves into his face and body, and into the softer pieces of the engine compartment of the car. One implanted itself into his eye socket between the bone and the eye itself.
One might also wonder why you never see a power engineer on the job while wearing a nice shiny metal watch. You'll find it is because that even across the terminals of a car battery, 12V and 500Amps of current truns your watch into a 6KW bar heater. In this sort of situation, you don't normally get to keep your hand.:(

I have heard that the MSN search suite is going be be an important part of Microsofts next generation file system. Are you sure that it will be so easy to remove then?
I have just discovered something worse in the last minute or so.
On this Win2K computer, if I type a random string of characters into the address bar, it opens MSN search and tries to resolve the name. This was discovered while attempting to load a.pdf file in the way the.doc file was loaded in my previous post.

"To start with they used a 40-bit memory address rather than 64-bit since we're not going to need 18 million terabytes of memory anytime soon."
Interestingly enough, it appears Moores Law States otherwise. Not only does Moores Law accuratly predict the increase in performance of processors, but it also seems to describe our lust for RAM capacity.
To present my point, Moores Law predicts that every 18 months the amount of ram we use doubles. Thus, we need to use one more address bit for every 18 months. This means AMDs choice of a 40 bit address bus only serves us for twelve years beyond the death of the 32 bit x86 microprocessor, and that is not including the four or so bits of hack space we have with PAE.
To paraphrase...
Who would ever need more than 16 bit memory addressing? Why, when with ten availiable pages of it we have 640K?

One of the interesting things about laser strike is that the gun produces the IR beam.
What I wanted to do is cover the players with IR diodes and put the photodetector on the rifle itself. This way, you could use an expensive sensor in the weapon for accuracy, and cover the player in inexpensive emitters. This will of course disallow the use of night vision goggles.
Each diode on the target player will flash in a combination or sequence that allows the system to determine where the target was shot. This would incur penalties such as leg shots, or weapon failure. A blood loss system could be used to determine when the player is no longer able to stand or fight due to the calculated loss. This would be managed by a server of some description, with data exchange over radio link, be it tones over an AM link or WiFi.
Finally, it would be fun to add a gas flash burner to the gun to make it crack when it fires. Night time laser strike would never be the same. Just no point blank shots though.:)
