Parhelia performance under DoomIII per John Carmack.

[K6-III]

Carmack has been unable to find a plant that'll sell it to him in the US, for fear of lawsuit (like this with anything aerospace).

If you know anyone at FMC and can change their opinions, that would be great!!!

Otherwise, if anyone knows anywhere abroad, that too would work.

He has rocket motors ready to test, but no propellant to fuel them with...

[GNEP]

Law-suits wise, he should definitely look outside of the US. It can't be that difficult to source? Alternatively, he can go to the local hairdresser's

The Parhelia board that is in my posession happens to be what I THINK may have been sent to JC as well (I have no possible way of confirming that) and it DOES perform faster than the retail version. I have no way of verifying the clock speed of this card either, other than it benchmarked about %10 faster than the retail version I had previously.

Does your board happen to support AGP 8x?

[DedicatedFan3D]

No it doesn't, hold off a second I am going to post some pictures of it.

All I know are:

It's about %10 faster than the production version.

It has a wire on it.

The PCB is a different color.

It's 128MB

It's a parhelia

And where did this come from? The BB Parhelia boards are all OEM clocked, I believe.

Hydrogen Peroxide? Quite powerfull stuff. Volatile. Hard to handle.

Unless kept in small volumes, stored at roomtemp. How about getting 100.000 bottles of bleaching liquid?


Just reminds me of the Head&Shoulder usefullness, from the movie evolution.

Lol.

Natch, forget rockets. Take the elevator. http://www.space.com/businesstechnol..._020327-1.html

Why not use water for the primary blast?

This is very cool, and could get the vehicle to escape velocity, or even just give it the first big boost...?

[K6-III]

He already has a vehicle designed for monoprop 90% peroxide that should scale to his X-Prize vehicle.

[Riddlewire]

The peroxide that is available to the general public is unsuitable as a propellant. Even if you could find it in a concentrated form (or concentrate it yourself), it contains many impurities due to its particular manufacturing process. The stuff needed for rocket motors is very high-end and requires expensive processing.

[K6-III]

While Technical and Food Grade are available and relatively inexpensive, HTP is very hard to find...

[K6-III]

Actually, concentrating it yourself using the freezing method is not too hard, just very time consuming for making sufficient volume.

Note that Carmack's vehicle needs 1600 gallons for the X-Prize flights, of which there will be several test flights, and 850 gallons for the initial flights with the fiberglass tank. On top of that, additional HTP is required for testing motors, as well as for oxidizer for thier experimental HTP-Kerosine biprop motors.

Should they choose to go biprop, they are also considering LOX as an oxidizer.

[K6-III]

Looks like I may have found some sources in Germany, France, and perhaps Sweden...

We'll see how they pan out.

2. For 3D artists? In fact we all know that the 3D guru of all platforms is SGI..no real proffesional will even look at a PC, never mind using a Parhelia for it...

I guess you don't consider the excellent animators at ILM (Industrial Light and Magic) aren't real professionals? They've all switched to PC's with linux. They've found that it can render things at about 5 times the speed.

The old system is so slow that the clones firing lasers appear to be throwing javelins. We've seen about a five times speed improvement with Linux, which is appreciated! I'd say Linux is one of the most successful efforts we've had. I can't say enough good things about it. It is intuitive, incredibly stable, and we can get stuff fixed at a moment's notice. Our renderer hasn't been ported yet but will be by the summer. That's all that's keeping me on the O2.

Quote from linux journal can be found here.

WOW !!!!

leech,

did you see this on the Linux journal page? I read that link and then went to the link about their PCs'

Is it possible for Linux to be too fast? ``Due to the speed of Linux, for the first time in my life, 15 years in the business, I'm starting to feel some RSI [repetitive strain injury]'', says Technical Director Robert Weaver. ``Usually you are working the machine, but Linux is so fast it can overwork you.'' Weaver has to remember to take breaks because with Linux he doesn't get any breaks waiting for the machine anymore.
