An older technical report of Rossi’s had an analysis of anode material before and after use in e-cat.

the claim was that from a nickel anode, some non radioactive copper was found after use.

but i also noticed some anomalous other materials had a spike on the mass spec; particularly, if i recall correctly, aluminum, and small amount of zinc were found.

the trouble here is that the copper was non radioactive. that’s very suspicious.

then if you know a thing or two about the finishing industry, it becomes clear: when you plate a piece of aluminum with nickel, it is conventional (because nickel will not plate aluminum directly), to apply zinc first, which will plate the aluminum, then copper, which will plate the zinc, and finally nickel, which will plate the copper.

and this begs the question: if no one else was given the anodes to examine, what evidence for any nuclear process exists?

we should note that previous planets were larger, mostly because it’s harder to detect small planets. it is also harder to detect planets in orbits that are like the earth’s.. (periods around one earth year) than those with shorter periods.

it turns out the fusion reaction is more energetic, p + 11B –> 3 He + 8.7 MeV; but for Focus Fusion, i expect the exit beam should consist of around 600 keV particles, or all the exhaust along with some unreacted fuel, in a tightly focused beam, before electrical conversion.

so i get a lower overall velocity in my estimates.
600 keV = 9.61305939 × 10^-14 joule, m[alpha] = 4.0026u = 6.6465 × 10^-27 kg, E = 1/2 mv^2; so velocity of the beam, v = sqrt(2E/m) is about 5.378 x10^6 m/s, or 1.8% of c.

we should keep in mind that fusion yield is not 100% of available fuel, (it might be 20%), and that 80% or more of the exit beam’s kinetic energy needs to be tapped to keep the reactor running for the next pulse, and that the entire process generates a good amount of waste heat to be carried off (up to half of all energy converted).

Even so, rate of fuel consumption is still extremely small. So overall thrust is small.

such current thresholds and field strength thresholds are just constraints to be considered inputs to the design.

gamma ray reflection isnt really feasible. schemes attempting to reflect gammas require very oblique angles, and it’s tough to guarantee of obliqueness from a bin of waste

as a low-numbered element, carbon should be relatively transparent to xray

i have no doubt such equipment can exist. but where is it today?

[vansig]

the launched energy ring is reminiscent of smoke rings, and is more-like the tri-alpha device i believe.

there are similarities to focus fusion but i don’t believe they have anything nearly as hot as DPF.
the clue is, no harmful radiation. that suggests low temperatures, although i would expect xrays from their device anyway.

[vansig]

the damaged assemblies are presently too hot to handle in those areas, both for humans and for robots;
so they’re stuck there, basically forever. you cant move them, and you cant abandon them to let the water run dry.

things will remain this way until someone can make a radiation-resistant robot capable of recovery.

so, how much will that cost? let’s name that tune..

i could do it if you hand me a cheque for $100M

anyone with a lower number?

[vansig]

hrm.. i thought i had this all worked out; now i’m confused.
but here is a pretty picture

rogowski coil efficiency is expected to be similar to that attained by large power transformers, and those are routinely around 99%. the rogowski coil ought to be > 80%.

[vansig]

only five orders of magnitude to go

Now, we could make this vertical grooves slightly Helical, (Rifled) This will induce a circular motion to the plasma, similar to the effect of the coil and improving the filament formation allowing to manage the plasmoid size.

The other potential problem with the helical geometry is someone has a patent on that approach.

existence of a patent was never and should never be an impediment to research.
