@SpaceInvestor_D @DrPhiltill Access to capital has never been Blue Origin’s limitation for progress. It’s been figuring out how to build the machine that makes the machines. If anything, the unlimited capital has been a hindrance as there was a lack of urgency when I was there compared to my time at SpaceX.

This seems right to me, intuitively If someone can productize this, feels big likely needs hardware and software tho
Seann Aswell@SeannAswell

@nunzi46 Have been wondering myself... It seems the simplest answer is ERP + real-time Metrics + Forecasting. Essentially current best-practices, with live querying of data for forecasting, which theoretically can improve efficiency...

Also Capital Founder @nunzi46: Too many startups vertically integrate without any real strategic reason. "You should not vertically integrate just for vertical integration's sake. It's a poor use of capital to take a bunch of equity and put it into a commodity machine, which you could instead not do." "I love the theory behind 'the factory is the product,' but there's some strong strategy that it needs to be built on." "SpaceX is a good canonical example. Why did they build a factory? Because they were creating massive demand at the same time they were trying to deliver it at a given unit price to unlock a bigger economic opportunity. There were no third parties even available. They had to do it themselves." "If you're going to build a factory in three years, you need to be thinking about it now. So - why are you building that factory? What competitive advantages does it give you?"

We’re back with round 2! Announcing @CapitalAlso’s second fund, $50M to catalyze founders solving hard problems Was a ton of fun breaking the news with @tbpn @jordihays @johncoogan 🙏 We’ll share more detail tomorrow, but for now we made this graphic to celebrate 🚀

@gerryhudak Frankly the engineering details are boring and tedious. Sure, could be anything. I want someone to start their explanation with, what if it could provide utility at XX% compared to all known alternatives.

The heat thing is a meme. There are levels to this. Initially you’re like: oh, this will never work. Then you remember space is “cold.” Then you do εσAT⁴ and think the radiator area might not be terrible. Then you remember bifacial panels and think you’re done. Then you remember the panel is also an absorber, so you don’t get a free cold surface. Then you remember the GPUs are in the bus, not smeared across the wings. Then you realize conduction over a 25 m wingspan is not casual. Then you find heat pipes to get heat from GPUs to the panel. Then you realize you still need vapor chambers to spread flux without hot spots. Then you decide on a pumped ammonia loop. Then you realize two-phase stability and pump margin are now your job. Then you realize you need rotary, leak-tight fluid joints for deployment/pointing. Then you realize “leak-tight” in hard vacuum for 5+ years is ambitious. Then you realize your structure needs a ~40 Hz first mode or it will self-excite. Then you realize stiffness is mass and mass is launch. Then you realize the mass adds up fast, and so does the integration tax. Then you realize launch cost was only half the problem. Then you start talking about BOM cost per pound like it’s Parmesan cheese. Then you realize flight hardware cost is labor, test, and yield, not raw materials. Then you start thinking about 2nd and 3rd order terrestrial supply chain constraints. Then you start wondering if Texas has enough LOX liquefaction capacity for cadence. Then you realize it’s a disgusting amount of electricity (GWh-ish per launch) to make LOX. Then you start wondering if there are enough trucks to haul that LOX. Then you wonder: do we need a pipeline? Then you wonder: do we have the natural gas to power those plants? Then you wonder: how do we spin up more plants and buy turbines from Mitsubishi? And boom, you’re back at NatGas turbines… on the ground… like God intended.

@yiningkarlli @shawmakesmagic @andrewmccalip from the calculator toy, looks like it starts to be competitive if launch costs get down to $150/kg (plausible if starship works), and satellite hardware goes down to $6/W from $22/W so actually it all rides on cheap satellite hardware

Yes, at first. I think SpaceX will start out with optically-linked satellites that are simply replaced as a whole satellite when they have too many internal failures. Eventually the architecture will evolve so they are physically connected as modular units, again each module replaceable in total. In the longer-run, the design could evolve toward smaller modules that are robotically replaceable.

@andrewmccalip After the sous vide, I prefer a nice sear on the grill. 4 min per side should do the trick.

Plan for tomorrow evening.... Sous vide the whole controller box so I can access the Pi and ESP32 ports. Wax will melt at 55c, well inside operational temps for everything. I'm still seeing Pi reboots nearly instantly after power cycles. Between 20 seconds to 10 minutes of SSH activity before it drops connection, not repeatable, and it requires a full power cycle to come back online. Starlink is being powered off the bench supply so it's out of the equation.

Working on root cause Starlink checks out, of course it's perfect, working flawlessly when I hooked it up to a power supply. What an amazing piece of technology. Should have never doubted it. Starlink team reached out and provided valuable insights on SNR. The fiberglass enclosure was bone dry. You can see the absolute overkill epoxy potting I did around the Starlink itself. It's 3m film adhesive bonded to the fiberglass lid, acting like an RF transparent radome. Problem is somewhere upstream, in the entombed wax filled box. I wasn't seeing any voltage from my mosfet that was delivering 28v to the Starlink channel. Something somewhere failed. And an intermittent failure at that. Maybe wax expanded and popped the FET off the PCB. Lots of questions that'll only be answered if I melt it all out. What a mess. It did it's job however. I'm on the fence about doing another rev of electronics. Maybe I will eliminate the PCB altogether? I'll dig through the onboard data and see what the heck was going on during the comms outage. It seems like the Pi and all sensors were online and happy during the entire trip. Batteries were fully charged and cameras were on when it was recovered. Super lucky to have it back. I'm through the trough of disappointment and now ready to get it back on the water. We made it 10 miles and the rudder, prop, and stability were great. No reason it can't go thousand if we fix electrical/software.

@andrewmccalip @luke_metro Even the green Duraseal? Definitely have some stories of dead hardware from using potting that was too stiff. Switched to Duraseal and it made it all better.

Potting compound would be great, except it's super super stiff and would crack some of the PCB during extreme thermal cycles (learned this from previous aerospace stories of PCBs gone wrong). We expect temps to range from 30f to 120f in the box. The wax is pretty soft, and cheap!

Project Bob’s brain is now hermetically sealed in a giant brick of wax. I bet that felt so good for the PCBs and Raspberry Pi 😂

@EganPeltan after controlling for test scores, students from poor families are disproportionately represented at Harvard, even more so than the top 1%.

Families with incomes <$200k will not pay tuition at Harvard (also at MIT, UPenn) Great use of endowment dollars, and a fantastic way to increase diversity. The sticker price of college has skyrocketed, but the net tuition has actually been falling meaningfully 👇🏾
