Ultimate streamlining of POWER ELECTRONIC PACKAGING:
* Si-on-Al lamination (9X CTE-mismatch!)
* Ultra-thin TPI bondline with extreme thermal dissipation.

@ianmiles Here's an excellent example of streamlining to design optimization. @elonmusk @JTLonsdale

Raptor 3 is an unprecedented step forward in rocket engine design, which will help us increase Starship’s efficiency and the amount of mass Starship is able to deliver to space

[Solid-State_Baseplate @SolidStateBased]

Concentrating that massive amount of electrical energy will require powerful electronics, that can be optimally built by directly bonding the heat-generating SILICON to the heat-sinking ALUMINUM. https://t.co/UJRqOZnMem

This huge streamlining of design eliminates electronic-packaging interlayers ... saving cost, complexity, space and weight.

@elonmusk PRO TIP: 'BELL CURVES' are healthy ... everything is relative.

That's how Nature has worked for billions of years.

[Solid-State_Baseplate @SolidStateBased]

Q: Is hollow-fiber SRO technology still around? There's not much on the interweb it.

Back then, we were talking about going to 1800-psi feed pressure, which enabled the maximum conversion rate, minimizing pre-treatment volume.

@IanCopeland5 Homosexuality -- where the brain does not match the body's gender -- is hormonal and natural, occurring in males way more than females: all embryos start female, only males need to transition.

[Nonlinear_Zero-Sum @NonlinearSum]

Human sexuality offers an interesting consequence and case study of the fetus's hormonal journey in the womb, and it's all in your head...

BRAIN SEX: https://t.co/3NuRC1vrud

The (literal) 'TRANS' reasoning:

* All embryos start as undifferentiated female.

* Within a few months, TESTOSTERONE kicks in MALE fetuses...

* Testosterone normally transitions BOTH the MALE BODY and BRAIN, from its original female state.

* In male fetuses where the body is hormonally transitioned, but the brain is NOT -- in effect, remaining 'feminine' -- that boy will probably be gay. Naturally.

* Of course, FEMALE embryos don't *enjoy* this double-journey of sexual-morphing on top of just growing into an infant ... and so have much LOWER VARIANCES in all aspects of humanity's metrics than males: intelligence, behavioral, sexuality, etc.

* The 'BRAIN SEX' theory is that both their XX-chromosome bodies and brains had some exposure to TESTOSTERONE while an embryo, and so physically and mentally develop somewhat MALE-ish. This is rarer than male GAYness, as observed.

[Solid-State_Baseplate @SolidStateBased]

Even back in the '80s, all the big SRO hollow-fiber plants had brine energy-recapture pumps (acted like a turbo-charger), although I don't recall the efficiency.

Qs: What maximum feed pressure do SRO pumps now deliver? What are the permeators' conversion rates?

[Solid-State_Baseplate @SolidStateBased]

@Rainmaker1973 Q: Are those powerful magnet fields that control the plasma from conventional or superconducting magnets? @NonlinearSum

[Solid-State_Baseplate @SolidStateBased]

@skdh As noted before, scientific progress -- whether in high-energy physics or high-performance materials -- was gelded when the Soviets were no longer an adversary.
https://t.co/5uqEFC5ftD

[Nonlinear_Zero-Sum @NonlinearSum]

Well, we used to invent cool sh!t, but...

Since the fall of the Soviet Empire, we've lost the goal objective of extending the performance of high-performance materials.

Enhancing communication and entertainment on flat glowing screens has become the sole focus. Pathetic.

@ericweinstein Dubya was also fuzzy on that whole *international law* concept. https://t.co/qJGTgc0QAa

Q: Does the 'Mansfield era' refer to this guy, the controversial conservative Harvard professor?

I do know him a bit, and he's quite the free thinker ... I'm sure Harvard was happy when he retired.

[Solid-State_Baseplate @SolidStateBased]

PRO TIP: Scrap the scary term *NUCLEAR REACTOR*, as it gives the technology a bad vibe ... and what 'reaction' is actually happening anyway, beyond a molecular transition in the uranium that gives off heat?

NEW TERM: *MAGIC ROCKS* boil water. https://t.co/nk1NWKHBpU
@NonlinearSum @engineers_feed

[Nonlinear_Zero-Sum @NonlinearSum]

Few people -- of either gender -- understand how simply nuclear energy is utilized...

IT JUST BOILS WATER!

...to turn a turbine.

[Solid-State_Baseplate @SolidStateBased]

@BADown1 @elonmusk @engineers_feed On that *PLUMBING* metaphor, equating electrical and water flow has long been useful for understanding system dynamics. @NonlinearSum

[Solid-State_Baseplate @SolidStateBased]

Like SpaceX engines, dramatic reductions in cost, complexity, space and weight are possible in HIGH-POWER ELECTRONICS packaging, by bonding the heat-generating semiconductor (Si, SiC, GaN) directly to heat-dissipating aluminum. https://t.co/xghjsnjPxs

[Solid-State_Baseplate @SolidStateBased]

That's an impressive application description, but out-of-my-league, photon-technology wise.

Q: Can you tell me more about the specific mounting of your heat-generating semiconductor chips to their baseplate for cooling?

I'm more of a *THERMAL PLUMBER* -- https://t.co/UJRqOZnMem -- and only focus on the system INTERFACES ... heat-sealing together dissimilar surfaces (such as semiconductor and aluminum) with a robust bond that can survive extreme-temperature exposure (cryo-to-300C) and thermal shocks.

[Solid-State_Baseplate @SolidStateBased]

Sorry to be a wet blanket, but further advancement in this military-aviation stealth technology probably dried up after the Soviet Union threw in the towel.

What you see is what we got ... no 'stealth' here.
@engineers_feed @elonmusk @NonlinearSum
https://t.co/7URfSxunV7

[Solid-State_Baseplate @SolidStateBased]

I'd worked on the team that developed the substrates for these stealth F-117 skins.

Interesting work, except no details were offered on anything but the specs of our custom polyimide-based film to be delivered for secret further processing. I guess these weapons programs require stealth all the way down the supply chain ... and apparently that strategy worked great!

*Government funded non governmental organizations*

Wow, what a sweet all-time contradiction in terms!
https://t.co/LlZRQXLgxe

[Solid-State_Baseplate @SolidStateBased]

@BADown1 @elonmusk @engineers_feed The proprietary TPI-bonding technology should be able to bond any semiconductor surface to any aluminum surface, with a bondline of only few microns (which can be highly filled with inorganic particles to optimize thermal or electrical conductivity, see below).

[Solid-State_Baseplate @SolidStateBased]

Again, sorry for the delayed response.

The direct lamination of Si-on-Al is a brand new (patented) technology that has been in-development over the past 10 years ... Si-on-Al is now optimized and ready-for-business.

Could you describe your PHOTON DATA TRANSMISSION application? Info about your existing electronic-packaging design would be most helpful.

[I'll try to respond sooner this time, if I can figure out X's nuances.] @nonlinearsum

[Solid-State_Baseplate @SolidStateBased]

The same principles in engineering-design optimization would certainly benefit ELECTRONIC PACKAGING.

Bonding heat-generating SILICON directly to heat-dissipating ALUMINUM would eliminate 80-90% of the systems' cost, complexity, space and weight.
