Andrew,
that’s wrong. No one who looks into this a bit more deeply is saying it generates thrust without cost.
Shawyer is saying that the cost is reduction of the Q of the resonant cavity, and that consumes energy
while heating the cavity.

If you try to build a perpetual motion machine with this, you will fail.

Paul March speaks of mass transients in this interview
https://www.youtube.com/watch?v=SmAbmCuO5tE

imagine, if you would, since we know that there is considerably more mass in our galaxy than
we can see, and we call this “dark matter”, that there is some way to interact with this dark
matter whereas ordinarily it passes through regular matter.

and isnt the carrier of the electroweak force is just such a particle? it can interact with
electromagnetism.

so hypothetically, we should be open minded about this notion of mass transients.

do not confuse the Cannae null test article with a control. it was a test article that Cannae had not expected to produce thrust, yet it did.
for that, Eagleworks has merely shown that Cannae’s theory was false.

i’m talking about how Eagleworks removes the 9.6 uN, that is part of the test apparatus, from each the tests to find ~95 uN or so net force.

“The (net) peak thrust observed for this tested configuration was 116 micronewtons and the (net) mean thrust over the five runs was 91.2 micronewtons. The net force is calculated by accounting for the null force present in the system. Null testing is performed by attaching the RF drive system to a 50 ohm load and running the system at full power. The null force testing indicated that there was an average null force of 9.6 micronewtons present in the as tested configuration. The presence of this null force was a result of the DC power current of 5.6 amps running in the power cable to the RF amplifier from the liquid metal contacts. This current causes the power cable to generate a magnetic field that interacts with the torsion pendulum magnetic damper system. The null test data is also shown in Fig. 20.”

the control produced a force about a magnitude lower, due to electric currents i think. they subtracted that from their tests

setting aside opinions on whether any particular “forbidden energy” project is real or not,
the winning submission ought to be one demonstrated to actually work.

some infrastructures use 50 Hz, some use 60 Hz. if you want to add anodes until you can get 1500 pulses/second,
(or 3000/s if you need it divisible by 200), then you should be able to convert this to either your 50 Hz or 60Hz rate.

[vansig]

as you may recall, end of july 2014 NASA presented some test results from this, which i’ll link here…

as far as i know they are a large scale industrial supplier, and if you think in terms of orders of 50 tonnes or so, they’re in the right ball park.

you might want to have a look at the beryllium-copper phase diagrams.

microstructures are interesting and their properties should be known if planning this

DIY vacuum pump and chamber

[vansig]

how much neutron radiation comes from one? my friend wants to build one anyway

[vansig]

you still get a trace amount of neutrons, due to side reactions

Most of the time, 40% conversion efficiency is because of thermodynamic limitations of Heat Engines… unavoidable.

by the way, heat engine efficiency reaches its limit based on:
(1) the high and low temperatures of the Carnot cycle, expressed as (1 – Tc/Th), where Tc is the absolute temperature of the cold reservoir, and Th is the absolute temperature of the hot reservoir; and
(2) the practicalities of the creep limit of stainless steel (about 530C or 1000F) and the condensation of water vapour at atmospheric pressure. if Tc = 100C = 373K, and Th = 530C = 803 K, then 1 – Tc/Th = 46.5%

but, the alpha beam conversion is a transformer. for those, 98% is routine, and up to 99.5% is in use in power generation and distribution networks today:
http://www.indiastudychannel.com/resources/163504-Energy-Management-in-Distribution-Transformer.aspx

and, while the onion still has to be developed, and we should justify the claim that we expect high efficiency from it, as well, the efficiency is expected to increase with xray energy, which will be up around 100 keV if i recall correctly.

if i recall correctly, total capacitance is around 120 microfarad, it is a capacitor bank, the caps must be pulse-rated, and 45 kV is on the low side of charge. if you’re sketching out plans for future, you’ll want up to 75 kV rated caps. the total current per pulse may reach 1 million amps for a microsecond or so, and rise time needs to be 25 ns or less.

also, the caps are mounted around a circle, onto a flat plate, with anode in the centre, to minimize parasitic inductance.
25 ns rise time corresponds to a max frequency component of 20 MHz.

[vansig]

didnt Google commit some funding awhile back?

[vansig]

yes, i see. but you never actually left focusfusion.org, so it’s a site config problem here, that occurred some time after i posted the link.
