strangely, i thought that chromatography could produce only small samples, and so was better for analytical use; whereas bulk samples needed something called a “vacuum arc centrifuge”.

okay i apologize for letting this topic off the rails by mentioning a reactionless thruster.

keeping it real and in the twenty-first century,
colossal carbon tubes have the specific strength needed for a space elevator.

if a climber could accelerate as it goes up, then at a modest 1.1g it would reach high subsonic speeds in five minutes.. at which point it would be ~44 km out.

at 300 m/s top speed, total travel time from surface to 30,000 km out would be ~28 hours. but after reaching space, it could perhaps go faster?

Actually I even wonder: what is the advantage of using a tether? Basically the only problem it addresses is avoiding reaction mass.

reaction mass is the single largest problem in rocketry!

it’s time for new physics; i want that reactionless thruster now, please. there may be no other way to get to the stars

decaborane vapourizes and dissociates easily; but it is toxic, and so are the reagents that make it.

i doubt borax dissociates as easily. but it is cheap, and easier to handle.

so the real question i guess, is: would the oxygen or the sodium in borax create problems in the plasmoid?

[vansig]

such effects are probably worth testing

I’ve already heard, today, the objection
“BUT they’re going to make H-bombs!”

which is NIMBY-speak for, “I have no idea what this means”.

time to educate the masses, folks.

if these are not erroneous, then the most direct implication is, that theory needs a bit of tweaking to cover the discrepancy.

new particles? perhaps.

a deeper understanding? probably.

a complete turn-over of subatomic models?
–now wouldn’t that be exciting?

the material to use is Colossal carbon tubes. these macro-scale fibres have the longest known breaking length. they are stronger, by weight, than nanotubes.

part of me wants to go ultra-low tech, here, and only use parts for this that were available to Benjamin Franklin in 1752.

a high Tc superconductor could have interesting effects on the plasmoid’s magnetic field, pushing it away from the anode; will a proper plasmoid even form?

Is there any reason why the sides of the anode have to be parallel? I understand that the cathodes in the cage have to be parallel to the anode surface, but what would happen if the whole thing was kind of conical? One thing is that it would allow more surface area and more internal plumbing volume but still let the business end stay on a tight radius? Or would the conical shape do something nasty to the plasma run down?

The patent allows for all sorts of shapes or profiles, and there are supposedly some advantages to a narrowing taper towards the tip.

i’m thinking that taper would become a really blunt cone, and the dimple facing the plasmoid could then grow to quite a large void.

the gallery photos reveal a lot, but
this would be easier to visualize if there were a 3D model of FF-1 around?

the terms of use reveals a bit more of how this works,

“New research suggests that misinformed people rarely change their minds when presented with the facts — and often become even more attached to their beliefs. The finding raises questions about a key principle of a strong democracy: that a well-informed electorate is best.”

No, it does not call into question whether a well-informed electorate is best. it drives it home, thoroughly.

those who believe it logical to conclude, from the above-referenced research, that leaders should, instead, misinform people, giving them memes that will support their delusion, have departed down a slippery slope that undermines democracy and freedom.

what is the veracity of the research, anyway?

i would ask Nyhan and Reifler how sophisticated were the test groups? ordinary, relatively uneducated people?

did they test uninformed and random populations against control groups who have been trained to think critically and question their assumptions?

the basic plasma pyrolysis process does not eliminate elements, it only breaks down compounds. to extract toxic elements, such as cadmium, arsenic, lead, etc., it would be necessary to combine this with something like a vacuum-arc centrifuge. with lots of energy, this could be made sensitive enough to remedy radioactive contamination, as well.

so profounder is probably a business development company or small business investment company, and that gets them their accredited status. i imagine, then, that they must obey a set of regulations that protects their account holders
