Is it possible to store stormlight in a nicrosil metalmind because it stores investiture?

Brandon seems to have answered this in 2015 and 2018 with a RAFO

Next up: can Feruchemical storage store stormlight?

You will find out exactly what it* does coming up

Questioner

Would it be possible for someone to store Stormlight in a nicrosil metalmind?

Brandon Sanderson

I will RAFO that for now, but you're thinking the way I want you to be thinking.

Nicrosil doesn’t store investiture it stores your ability to use investiture so if you were a radiant feruchemist you could store your ability to hold stormlight.

this doesn't seem accurate to me. If it only stores your ability to use investiture, then it doesn't make sense for a Nicrosil metalmind be able to form a perpendicularity (piercing the Realms), which Brandon confirmed it could. It seems to me that you're thinking of Hemalurgic Nicrosil. I would love to hear any evidence you have for your claim that I might have missed though.

Could you Invest... Could you use a nicrosil metalmind to Invest the sort of Investiture enough that you could open a Perpendicularity up to the Cognitive Realm?

Brandon Sanderson

So, I'll just say it this way. Enough concentrated Investiture in one point is going to pierce the Realms, no matter what form it takes. 

TheFulgid

...So, it doesn't have to be a nicrosil metalmind.

Brandon Sanderson

No. 

TheFulgid

Okay... But it could be?

Brandon Sanderson

Yes. That is theoretically possible.

edit:

I found this WOB a little later that is the closest thing I saw to supporting your position, but I think it's pretty unclear exactly what F-Nicrosil does.

Could Feruchemical nicrosil be used to store other Invested abilities, such as a Returned Breath or the abilities of the Knights Radiant?

Brandon Sanderson (paraphrased)

Yes, that's possible.

DragonCon 2016 (Sept. 4, 2016)

it seems to say that they could store the abilities, but other WOBs seem to say you can store the Investiture itself, so it seems ambiguous to me.

Nicrosil Feruchemy is meant to be a major component of Era 3, Brandon has refused to answer all questions about it.

You've dropped a few tidbits about the plot of the next Mistborn series over the years. Putting all those things together, we have a nicrosil Ferring Terriswoman hacker recruited for fieldwork in an "Allomancer SWAT team" to chase a Mistborn serial killer. Could you give us a more recent and concise pitch/blurb if the above is no longer accurate?

Brandon Sanderson

Ha. That's not far off, as all of those things still exist in the series, though the weight I'll give them is relative. With the Alloy series covering some of the police procedural aspect of storytelling, I'm inching the outlines slowly away from the SWAT idea and toward more spy thriller--but the SWAT team isn't not gone completely. (Of course, who knows what will happen in the intervening years between now and when I write it.)

Well, we dont actually know yet.

All we know is they play a major part in unsealed metalminds, and can 'store investiture' but Brandon RAFOed all the specifics
