Therein lies the quirk.

Pyroelectric fusion was reported in April 2005 by a team at UCLA. The scientists used a pyroelectric crystal heated from −34 to 7 °C, combined with a tungsten needle to produce an electric field of about 25 gigavolts per meter to ionize and accelerate deuterium nuclei into an erbium deuteride target. Though the energy of the deuterium ions generated by the crystal has not been directly measured, the authors used 100 keV (a temperature of about 109 K) as an estimate in their modeling.[9] At these energy levels, two deuterium nuclei can fuse together to produce a helium-3 nucleus, a 2.45 MeV neutron and bremsstrahlung. Although it makes a useful neutron generator, the apparatus is not intended for power generation since it requires far more energy than it produces.
Shows a bit of promise.

It's been so long since this adventure started that I've forgotten why exactly an axial flow supercharger is superior. I'd rather not have to read through everything again and I was wondering if someone could quickly tell everyone why this is better than a normal supercharger or turbo?
You don't have to read the whole thread. Most of what you want is in the first five pages. That is when the entire forum was asking the same thing.
By the Trugell I like that title, I think I'll keep it.
I mean if Richard Petty can do it...........so there are two King Richards. Maybe that's why I'm the third?
Not that I can compare to his record of achivements. He truely is a King, but what the hell.

Isn't that what you asked?

carBONE, how's the chemistry and sashimi going? your intellectual prowess was so impressively irrelevant. are you ever going to finish hornet high school?

'Course, im a geek also.
A geek with a pretty car though

Hey, sarcasm is fine but no insults, not on my thread anyway. I have friends who are mods and they are bothered by the legnth of the thing now.
Are we waiting on engine management here? Given that there are flash tuners coming out, and you may be looking at this option, I would personally like the ability to dyno tune this blower for the rest of my mods with an ECU like the Interceptor. Any updated thoughts on this?

RP what is the Boost Vs engine RPM profile/equation with the current compressor?
I know the relationship is linear just what is the profile
1psi : 1kRPM;
1.5psi : 1kRPM;
2psi : 1kRPM
Ect ???
And also how would the ratio change if you were to add stages to the compressor to put out 10,11,or 12psi max
Knowing the maximum boost is based on max engine rpm and compressor design (compressor stages) I would like to calculate the boost amount at any RPM assuming WOT

Assuing efficiency stays constant as rpm's rise, it would be a direct ratio of rpm vs boost. As an example if he set it up to run 8 psi at 8000 rpm, it would be 4 psi at 4000 rpm, 2 psi at 2000 rpm, etc. He has played with the blade design to give different efficencies at certain rpms though to get the curve he wants so this may not hold exactly true. I also don't know what boost level he wants to run. The axial flow is a pretty steady boost rise with rpm as compared to a centrifugal which has boost rise as the square of the rpm (not sure if I worded that properly but you get the idea).
