No changes recently, but changes made earlier this year just before things went black are detailed.

Interesting to see before and after. In particular...
+ Phase 1 validate & review WB-6 becoming validate & entend and the forecast $3-5M over 2 years came in better than expected at completed for $1.8M over 1.5 years.
+ The split into Phase 2 & Phase 3.
+ Phase 3 being "in-design" for "full scale 100MW" - which I guess finalises previous discussions regarding 100MW versus 100mW.
In theory there is no difference between theory and practice, but in practice there is.

The "full scale" is WB-D, the WB-9 may or may not be 100mW. Two different machines?

Folks, please get it thru your heads that the web site being quoted is for "EMC2 Fusion Development Corporation" a not-for-profit target of the New Mexico Community Foundation and which has a plan to design the WB-D. It is NOT the same as EMC2 Corporation, the company that has a contract with the Navy for designing WB-9 if things work out.

True, they are quite closely tied, but not identical. :wink:

Thanks for that, never had caught that distinction.

I never understood why anyone thought they would build a net-milliwatt-output machine. You'd have a hard time even measuring that against the necessary inputs to get to breakeven.
n*kBolt*Te = B**2/(2*mu0) and B^.25 loss scaling? Or not so much? Hopefully we'll know soon...

I'd agree, but that is where previous discussion went, and I didn't remember a firm conclusion.

I am the one who holds out the possibility (not conclusion) that it means what it says. My logic, if that it be, is as follows.

I am embarking into a field (full scale fusion POWER OUTPUT) that has never been entered before. I have a LARGE number of interests who may object to my success. I am not positive I will be able to hit the target I shoot at, but suspect I will do pretty well.
  • * If I announce a 100MW target and I get 1 kW, I am an abject failure.
    * If I announce a "100mW" target and get 100MW I can say "but of course everyone knew it was a typo!".
    * If I get 1kW I can say "Oh boy, things were better than designed. Now lets go for 100MW!".
See? Its called CYA (cover your a$$).

I am one of the 100mW school. It may be a typo or not. But a 100 mW steady state (for seconds at a time) machine that produced 100mW of fusion power (not 100 mW net- positive energy output) would answer a lot of critisisms about thermalization times, maintainance of potential well, etc. Also, with 300 neutrons detected per ~ 0.25ms instead of a statistically impercise three would greatly improve the precision and possibley the accuracy of the data. This would allow much better confidence in the scaling issues. If the magnets could be made to run at ~ 500-10,000 Gauss steady state, and the drive potential could be varied from ~ 1000 to 50,000 volts the magnetic scaling and the crossection scaling and their interactions on thermalization, bemsstrung, etc could be useful. Such a machine could also double as a P-B11 testbed. Fusion alphas should be easily detected, even if the P-B11 resonance peak is not utilized if the run times are seconds instead of fractions of a millisecond. Also, the distribution of alpha impacts on the wall could confirm expectations and aid in the design of direct energy converters and possibly vacuum pumping stratagies. All this at presumably much less cost and shorter time scales compared to a full scale demo machine.*

* Maybe! I recall that the size and magnetic field strengths have to reach a certain level before the alphas gyroradius is less than the machine radius, so that the alphas will only exit at the cusps, and not hit the magnets.
