more 1984-land propaganda. they also claim to have a satellite in orbit, broadcasting on FM. but North Koreans don’t own radios, so they cant debunk their own claims.

it is possible that NK could make a working Farnsworth fusor, and begin a fusion research programme. i would love it if they could really reach break-even, but it hasn’t happened.

Would a wide band gap semiconductor do, for this purpose? such as
Aluminium gallium indium nitride (AlGaInN) ?

wasn’t 70 keV ion temperature reported this spring? that places Focus fusion just a few ticks from the right-hand edge, within the yellow zone.

In my opinion, Kurzweil’s Singularity occurred circa 2004.
Ever since then, just about anything i imagine exists when i search Google for it.

you want to pull the viewer in, emotionally, so that they’ll read the text.
but I don’t think that poster, in its current form, quite does what you want.

seems to me that this is much like trying to capture the energy from a lightning bolt.

what if you get a stack of toroidal coils, of increasing inductance as you move farther from the action?
the faster particles punch through to the last coil, but slower particles are stopped earlier.

*sigh*. if only they could be fined for not using RESTful architecture, we might at least get them to spit out an abstract, reliably.

I was corresponding with some electronics nerds about FF1’s architecture, and one suggested to try losing the capacitor bank altogether, and turn the system into a resonant circuit. Maybe keep the capacitor bank in, to charge the first shot, but switch it out and power the next shot directly from the collecting coils

BTW: The largest market of GE’s 2 MW gas turbines in shipping containers is Pakistan (even before the flooding), because there the grid is so bad, that companies and communities want backup systems to provide their energy needs without much outage.

Nigeria could use a few, right away. Seems their electrical grid was mentioned on BBC world news, just yesterday

The more I think about this the more convinced that the optimal solution is only going to be found by running simulations. There are just too many variables to figure out the best solution.

right. there could even be multiple bursts of high-speed particles coming off. we don’t know, yet.

in lay terms,
they’re blowing smoke rings at each other. or, in this case, ball lightning.

some number of years ago, their web site claimed that they could create plasma toroids at ~1 atm pressure. if i recall correctly, they were attempting to fire a pair of them towards each other inside a tube. in my opinion, they’re not anywhere as close to unity as FF is.

anyone have a clue yet as to what the raw output voltages might look like?

… still assuming that the net power comes from the onion…

both onion and ion exit beam could yield raw voltages from 50 kV to 2 MV depending on actual circuit design

Stealth mode isn’t the thing that draws big money. It’s the size of the investment (~ $100M), and they get there by successive iterations of match funding.

If you only ask for another $1M here and there, then those people with deep pockets wont take you seriously.

Produce an R&D and deployment plan and schedule that will bring the installed base to 1000 generators; then ask for the amount of money that will cut that time in half.

Let’s say you design your system to go after particles of 65Kev and were able to capture all the energy from them. Any particles of energy less than that would be decelerated, stopped and reversed by the induced magnetic field. Accelerating them back into the reaction chamber and taking some energy with them. Any particles faster than that will still have their residual velocity (the amount in excess of 65Kev ) when they reach the helium catchment container (Which thus may need cooling.)

Wont the speediest ones come out, first?
Let’s design the system to allow the particle velocities to stratify.

The effective coil length would then change through the duration of the exit beam.

From off-the-shelf parts, too. That’s the bit I want to see. Nikola Tesla worked with high voltages. Can we use only parts that were available to him? Can we turn the way-back dial even farther back, and use only parts that were available to Benjamin Franklin? That would make me really happy.
