I believe you’re thinking of inverters (DC->AC), not of rectifiers (AC->DC). That’s actually the beauty of FF, because you already get a inverter for free. Output capacitors are already required, otherwise you’re getting only impulses of a few milliseconds.

Or are you’re thinking of eliminating those output capacitors? And replacing them with what? Inductors of the same size? Not much gained (but might be cheaper).

I’m thinking of computerized control circuit which switches the several capacitors onto the grid depending on demand and circuit phase. You still need an inductor for leveling out the edges, but you need them anyway. So it’s an computerized inverter. I think the modern ones are computerized anyway.

You can compare this to modern automobiles with their computerized ignition systems compared to primitive distributors in cars twenty and more years ago.

Or if it’s of Rematog’s big-scale utility (200 FF generators), you might orchestrate them to output something that looks like a sine wave. You then don’t even have something with a stable frequency, it’ll look much more like you’re Windows Task Manager with two processor cores running on 50% speed (because the process running is only built for one processor). The load jitters between them two.

Going “black” of FF is not too far fetched. That’s the reason why Eric and Rezwan are doing their best to go public for avoiding the big players silencing them. Even in LPP’s business plan it is encased, that no investor can control the technology. 51% stays in Eric’s realms of influence. And I trust him with that, being a revoluzzer as he is.

You actually don’t need a multiplicator of 60Hz (or for sensible areas of the world 50Hz) of shot frequency to get AC. So a shot frequency of anything like 512Hz and 435Hz the next minute works. Energy is stored in capacitors and can be drained in a controlled fashion. You’ll probably need to double the number of output capacitors to get it running smoothly, switching between the banks at each shot. But that gives you the advantage that you’re utilizing the generator only for the amount of energy required.

The main reason why utilities like it big, is because they’re big. Any small stuff enables competitors to enter the market.

From Nanosolar’s blog: 1kg CIGS = 5kg Uranium

CIGS is a copper based semiconductor apparently used in their product.

This should read actually 1kg CIGS >= 5kg Uranium because that’s calculated with their minimum warranty. Ok, now just say they’re using it only in Sahara, then we’ll shall divide that by five for other locations maybe? Then it’s still 1kg CIGS >= 1kg Uranium.

Are all the wires leading from the trigger box to the switches exactly the same length? i.o.w. as long as the longest one needs to be.
Even light speed is not sooo fast when it comes to nanosecond precision….

Maybe a good idea for leveling out the last few ns to have wires of different length. It’s about 30cm per ns, see http://www.wolframalpha.com/input?i=lightspeed+*+ns (the forum software swallows the star, you have to fill it in yourself).

But then you’re adding additional inductance, and I somewhat doubt it’s a problem of the wires from the capacitors and more one within the triggering system.

Yes I think it should be possible to add an extra section of Focus Fusion (in capitals) into the Eric Lerner article, just before the book review. But by all means it has to be checked by Aaron, and redefined here a few times. He has more experience dealing with Wikipedia bureaucrats. Also one picture like one of the following should be included (maybe take another one of the fully assembled device):

https://focusfusion.org/index.php/gallery/image_med/81/
https://focusfusion.org/index.php/gallery/image_med/79/

Something along these lines:

Focus Fusion

As an ongoing experiment Lerner currently conducts research with a Dense Plasma Focus (-> Link to DPF) built at his company Lawrenceville Plasma Physics, which shall reproduce and surpass the conditions allegedly achieved in experiments conducted at Texas A&M University (-> Link to Texas A&M University) by him and others, with which he tries to accomplish fusion of p11B (-> Link to Aneutronic Fusion).

The DPF is constructed with the following characteristics:
Peak-Voltage: 45kV
Peak-Current: 4MA
Inductance: ???mH

On 2009-10-15 the device pinched the first time with 20kV and a peak current of about 0.9MA on the second shot using helium as fuel. (citing https://focusfusion.org/index.php/site/article/lpps_newly_assembled_dpf_achieves_first_shots_and_pinch/ )

——————————————————————

That first section only includes the claim (the rationale), and the rest is pure facts. Additionally the fact section needs to be more spread out, but not too long, before anyone cries out: “Unrelevant! Let’s do more Electric Universe bashing.”

Bussard’s Polywell also has a lengthy article of its own. The rationale goes something along this (in the talk-page of the Polywell article): Dr. Bussard was a well known and respected fusion scientist, therefore we have to include his not commonly supported fusion device.

And the rationale about Focus Fusion seems to be like this: Eric Lerner is a commonly known crook who supports an Electric Universe and questions the Big Bang. So we do not include any scientific work, and just hack about the book he’s published.

Take a look at the Spanish electrical power supply. Last few days have been quite windy. Especially take a look at 2009-11-08 (that’s 8th of November 2009 año del dios). More than half of Spanish power production has been accomplished by wind (light green area, called Eólica). Then add 20% of other regenerative production (dark green area, Resto reg. esp.).

That energy has been fed into the grid, because the meteorological office could determine time and location of favourable conditions, and advice the other producers. No power outages occurred.

Therefore regenerative energy production is viable for Spain. If they continue their efforts like the last ten years, they’re more or less set.

Conventional energy production is a backdrop, if the doesn’t blow enough, the sun don’t shine. Nuclear (fission energy) is a money dump – you need to clean up the mess afterwards, nuclear waste and nuclear sites. Aneutronic fusion is still a dream and will as well stay that, although we’re working on it but DON’T COUNT ON IT!

So stop whining about “regenerative energy will never make it” and “there is no greenhouse effect”! Period.

Ok, you’re right. This should read LEO then. So the second stage needs to ascent from about 14km (WhiteKnightTwo) to 160km (LEO), and not just 100km (Kármán line) like SpaceShipTwo. But they’re both arbitrary definitions. So somewhat between that.

[Henning]

As we’re going off-topic once more and raving about space elevators and stuff, I would like to propose a more economic way for going into orbit and beyond in a near-term future. For that purpose I started a different thread Space and Aerospace Design in a Focus Fusion World. This post includes various other ideas floating around in this forum.

Well, we could prepare the initial wiki page at Plasma-Universe.com, just as zeuz explained at the forum article Alternative wikipedia site for plasma cosmology.

zeuz describes the goals of the site’s owner Ian Tresman in his post. As long as we respect him, I think he’ll be happy to let us elaborate the focus fusion article. Again we should emphasise it being an ongoing experiment, and not touting it as a miraculously wonderful magic technology.

After everyone agrees (including Ian Tresman) focus fusion as being described in a neutral way, it may be uploaded on Wikipedia. But as it being a formerly deleted article, we’ll have to jump some hoops again.

[Henning]

The D-D reactions are just to clarifying that fusion actually happens. The neutron count as deuterium nuclei bounce together and overcome the repelling force is important here. That’s how you determine the force of nuclei colliding, and that there’s not just the colliding x-rays produced by bremsstrahlung.
