Does anyone have a nice collectible signed by the Artemis II crew for sale? Please post it below. I have a young, future astronaut whose birthday is coming up who needs something for his bedroom wall. Something to go along with the STS-1 crew!! ๐ ๐ง๐ผโ๐ @SpaceX@NASA@HubbleTelescope@rookisaacman
@mattvanswol Respect. ๐ซก
wrt the assailant, just hang him. Taxpayers do not want to pay $70k-$100k per year for the next sixty years to keep this animal clothed and fed.
Single Crystal CVD Diamond
Have no doubt, you are at the dawn of an industrial revolution. There is a string of breakthroughs happening throughout upstream industries that all compound.
Diamond manufacturing is now able to produce CPU size single crystals wafers.
Currently these are marketed as heat spreaders because they have thermal conductivity of 2,200 W/mK which means they move heat incredibly effectively.
However, that somewhat misses the wood for the treesโฆ
Diamond has physical and electrical properties that exceed traditional silicon, making it uniquely suited for high demand applications.
Thermal Conductivity: Heat is the enemy of electronics. Diamond conducts heat better than almost any other known material, about 5 times better than copper and over 10 times better than silicon.
A diamond chip can act as its own heat sink.
Ultra Wide Bandgap: Diamond can handle massive amounts of voltage and operate at incredibly high temperatures without electrical breakdown.
This makes it perfect for high power applications like electric vehicle inverters, power grids, and aerospace technologies.
High Frequencies: Electrons move very quickly through diamond, allowing chips to operate at much higher frequencies, which is ideal for advanced telecommunications and radar.
Radiation Hardness: Diamond is incredibly resilient to radiation, making diamond based chips ideal for satellites, space exploration, and nuclear facilities.
To make a material act as a semiconductor, you have to "dope" it. To do this you inject impurities into the crystal lattice to create a positive (p-type) or negative (n-type) charge.
Diamond's atomic structure is so tightly packed that forcing other elements into it is hard. While p-type doping (with boron) has been figured out, reliable n-type doping (with phosphorus) remains a massive hurdle.
Theoretical ceilings
Band gap
Silicon wafer = 1.1 eV
Diamond CVD wafer = 5.5eV
Clock speed
Silicon wafer = 5-6 GHz clock wall
Diamond CVD wafer = 1-2 THz clock wall
Max Running Temp
Silicon wafer = 150ยฐC
Diamond CVD wafer = 1,000ยฐC
Whilst we etch silicon with photolithography and Extreme UV light, this doesnโt really work with chemically inert diamond.
Diamond CVD is currently etched with oxygen plasma etching, but this lacks the precision of EUV.
However, we can etch diamond to extreme precision with electron projection lithography. EPL was invented in the 90s by Bell Labs, IBM and Nikkon but abandoned as it was harder than EUV.
Electrons repel each other so the beams blurrs too readily.
What if we built a femto electron beam?
What if we built it to extreme such that it was a โsingle electronโ pulse?
What if we build a microscopic "bed of nails" containing millions of nanoscale tungsten or silicon tips (photocathodes). You shine a massive, highly complex femtosecond laser system across the entire array.
Every time the laser pulses, millions of tiny tips each fire a single, perfectly straight electron at the exact same time.
Turns out, research teams at likes of MIT and Stanford are currently experimenting with exactly this, laser driven nanotip electron emitters.
Pair that tool with Diamond CVD substrate tech and we approach the material limits of both semiconductors and nanotechnology.
Would require asynchronous logic to escape fatal clock skew and operate at full capability.
But I think I will live to see it.
@SenSanders You, sir, are a communist who leverages the misery of others to continue the graft and corruption - the lowest, most morally bankrupt type of individual to walk the face of the planet.

๐จ DIAMOND IS ABOUT TO REPLACE SILICON IN NEXT-GEN CHIPS.
Scientists are now producing large single-crystal CVD diamond wafers that could revolutionize electronics. Diamond conducts heat 5ร better than copper and over 10ร better than silicon while also handling extreme voltages, high frequencies, and radiation.
Why this matters:
โข Thermal Superpower: Diamond acts as its own heat sink, solving one of the biggest problems in high-power chips
โข Ultra Wide Bandgap: Handles massive voltage and extreme temperatures without breaking down
โข High Frequencies: Electrons move incredibly fast, perfect for 6G, radar, and advanced telecom
โข Radiation Hardness: Ideal for satellites, space tech, and nuclear applications
The deeper implication is massive:
Weโre at the early stages of a materials revolution. As silicon hits its physical limits with heat and power, diamond one of the most extraordinary materials in nature could power the next era of AI chips, electric vehicles, and aerospace systems.
What do you think will diamond semiconductors become mainstream in the 2030s?

Civilization is drowning in mediocrity and starving for Beauty.
It is one of the things which reminds a civilization that life is worth living.
Cathedrals, poetry, music, sculpture, architecture, gardens, great stories are civilizational necessities.
A society which stops striving for beauty eventually forgets what it is striving for at all.
