Lots of us would love to believe this, and yet what does the unrestrained private sector churn out? Ad networks, app addiction, gig economy, throwaway culture, urban sprawl, climate apathy... hardly a winner.

SpaceX is everyone's favourite private sector success story, but they're basically just a younger, leaner version of Lockheed— surviving off of NASA and doing what they're contracted to do.

I don't think the private sector is ever going to do ambitious things like build rail infrastructure all on its own, nor is the current PPP model necessarily the way either, but maybe there is some option out there to get things done which looks like the bakeoff that NASA held with CRS.

In 2020, SpaceX did 26 launches. Only six of those had NASA as a customer. The rest were a mix of US military, commercial customers, foreign governments (Argentina and South Korea), and Starlink. Even if you add up NASA and US military, that's still only nine out of 26 with the US government as the customer.

So while no doubt SpaceX does benefit from NASA's business, it is now only a minority.

[mikepurvis]

Sure, and legacy launch providers do business with the private sector also, but none of them could have been bootstrapped without years of unprofitable R&D on the public's dime.

There is no VC who would have accepted a pre-SpaceX pitch for low cost launches, Starlink, or any of the rest of it. It would have been straight up "lol Iridium amirite, get out."

SpaceX was funded by Elon Musk and later, Draper Fisher Jurvetson and Peter Thiel's Founder's Fund. Starlink has been in part funded by a $1 billion investment from Google and Fidelity. And since then further funding rounds have been raised.

The DFJ and Founder's Fund investment was before SpaceX had any substantial NASA development contracts, let along their 2008 $1.6 billion launch contract.

[mikepurvis]

Interesting, though I don't know if any of that really disproves my point. Musk's own money was a self-investment; he didn't need to pitch anyone for that. Jurvetson was involved with Tesla prior, and Thiel was obviously connected through PayPal.

Until the Dragon demo flights in 2012-2013, I think SpaceX would have been hard pressed to raise significant capital from anyone other than Elon's friends. I think the fact that so many private space companies have one or more wealthy benefactors bears this out (Blue Origin, Virgin Galactic, Armadillo to a lesser extent).

There's a wide gulf between "only a few people with the right skills and personal connections can bootstrap a space company" and "none of them could have been bootstrapped without years of unprofitable R&D on the public's dime"

[p_l]

The missing bits is that they bootstrapped after a lot of heavy lifting was done on public dime, and then landed a crucial bunch of govt contracts way before first succesful draco launch, the same kind of contracts that the previous private contractors also take.

I'd love to come up with examples as I type this to you from an open source web browser on a smart phone that contains more functionality than $20K worth of equipment did with more processing power than what all of NASA had in the 70s and access to more information than President Reagan had in the 80s and a faster throughput than anyone had in the 90s all hosted on a self made website by a startup platform helped fund and inspire hundreds of successful companies as I wait for my sushi dinner to be delivered to my door and take a break from my telecommute to work to hack out this absent minded response to you, but I'm drawing a blank.

Another Musk inspired project is the hyperloop and of course the Boring tunnels for electric cars. These are novel transportation solutions that solve for the problem in a more creative way than simply "build more light rails". That's the type of stuff a government will never come up with. There needs to be a creative maestro with massive capital. Musks are rare in the world but they certainly can move in a more agile way when they do appear.

I would also argue, telecommuting has solved for some of the transportation problems alone. Think of how many less cars are on the road as a result of work from home.

[mikepurvis]

The thing that's different between Boring/Hyperloop and SpaceX is that SpaceX's entire business case is built on the cost benefit of landing and reusing a rocket, an idea for which the napkin math was obvious and in the end turned out to be extremely feasible but which legacy providers had been unwilling to even try.

Boring/Hyperloop don't have an idea like this. Boring's pitch is using conventional TBMs but making it cheaper by digging a smaller-diameter tunnel than the other guy. Does that meet the requirements? New subway systems are also reducing tunnel diameter by using LRVs instead of heavy rail cars... is there an actual innovation here?

Hyperloop is full of practicality issues, and addresses none of the real problems that are barriers to high speed mass transit projects today— specifically the fights over rights of way and station locations. The fact that it was initially pitched in 2013 as a system for moving around private automobiles should tell you a lot about how much understanding there is of the first principles of transportation— it wasn't until years later that this was acknowledged and corrected [1]. It would be like someone proposing an airline where each plane carries 10 cars instead of 400 passengers ("so convenient, you just drive right on board!")— it doesn't matter how fast the trains are, 840 passengers per hour for a Hyperloop would be a complete nonstarter when a normal subway does 40k/hr.

Maybe Boring/Hyperloop will end up pivoting into something worthwhile, but at the moment there is good reason for skepticism.

The cost of reusing a rocket has not been proven to be cheaper than building a new rocket. Consider factors like the inability to reuse the entire rocket, the reduced payload. At best you can break even. Unless you somehow reuse the entire rocket and do 100 flights with the same rocket the savings are meager.

This isn't something new. The space shuttle suffered from the same issues. Building new shuttles was almost the same cost and less risky.

[mikepurvis]

I think it's pretty obvious that the current gen F9s are way more reusable and with way less refurbishment than the Shuttle ever was, even with the disposable second stage. But yeah, there are limitations, which is part of why FH is effectively cancelled in favour of just flying those payloads on a disposable booster.

But now that the basic principle has been proven, really leaning into it is part of the point of Starship— a new clean sheet design that is built for full reusability from the get go.

>Another Musk inspired project is the hyperloop

He just took the 100 year old vac train concept and repackaged it. Back in his original pitch he constantly said and laughed how easy it is. Once the years went by he slowly backed off from every promise and ultimately reduced his involvement to 0.

> of course the Boring tunnels for electric cars.

He promised to make tunnel boring cheaper, yet his only tunnel costs exactly as much as every other tunnel. He constantly advertises 150mph travel when the tunnel isn't even long enough to reach that speed. Have you seen the tunnel? It's so tiny you can't even open your doors if you get stuck in there. If even a single car fire starts in that tunnel everyone in the tunnel will die.

[Bakary]

Cars themselves are pretty wasteful in terms of space and the way they rearrange the urban landscape. The concept of the Boring tunnel actually sounds like someone in 1894 wanting better spaces for horse carriages, except even more wasteful in this case.

Really this is more similar to VC investment where NASA funded it so they could get a return (better launches), but the future is that a probably large percentage of launches will be for commercial purposes (~50% of 2022 launches are for Starlink).
