@Explosions_Fire
I make Youtube videos on chemistry and energetics occasionally. Would do more but it's hard ok. 'Backyard Science' 🇦🇺

@MattGialich Are you wanting to mine metallic or non-metallic asteroids? Hard to tell from your phrasing and always very interested in this stuff
English

This image was taken of a 30M wide Near Earth Asteroid. This is now the smallest asteroid we have ever visited as a human species.
The only issue, this was taken by the Chinese Tianwen-2 mission. This should be a wake-up call. America is no longer guaranteed to be the dominant force in space exploration. We are losing ground, fast.
This object is not metallic, the asteroids we want to mine. Telescope spectra are consistent with it being silicate rich, and one reputable study suggested it could even be an ejected fragment from Earth’s Moon.

@endless_sine Who is going to read the harsh reviewer comments then? Will someone else do your minor corrections to ensure it does get published sometime in the next 14 months?

@DeltaClimbs @vc What about copper/diamond or silver/diamond composites? Could probably CTE match it to the SiC
English

@vc That's when we would start considering graphite materials that require thermal barrier coatings. Pitch carbon fiber composites can have exceedingly high thermal conductivity in axis, but would have to think about how to orient given not great off-axis properties.

People keep asking me for this pan
If any VCs want to come in with a $500k pre-seed check at $5m cap we can cook
You want hardtech? At 30 GPa Vickers, silicon carbide almost goes as hard as me
Delta, Dirac@DeltaClimbs
I am building a cooking pan. 3 years ago I asked myself, "if I threw budget out the window, and made the best possible pan that won't be ITAR-restricted, what would I do?" Finally got around to it. Sintered, mirror polished silicon carbide. Single block machined carbon steel. SiC will get molybdenum PVD coating on bottom, and then 80:20 silver copper layer will be used to vacuum weld the two pieces together, and provide a softer interphase layer to relieve CTE mismatch strain.

@Explosions_Fire Brother why do you grip the holy fish so
English

@GlowHobbit I genuinely think that a fillet of fish bought in Australia is 75% LPG. McDonald’s have not stated otherwise, and it checks out
English

@Explosions_Fire How flammable can one make a filet-o-fish?

@hexane360 im still eating it. Little at a time, pacing myself

@EggyManSam @cluckingchooky Yeah kinda feel bad for the charity, they probably planned this campaign long in advanced and it’s lined up so badly. But also, it always seems like such bad energy to force customer service staff to push charity donations at big chains
English

@cluckingchooky @Explosions_Fire lol I may work there and we have the red kite fundraiser on atm that they’re really pushing us to ask everyone
