<b>Potential for Fueling Starship with Food Waste</b>
As a fan of SpaceX and a waste management professional, I was excited to hear about Starship being Methane fueled and became interested in estimating the potential of using Food Waste (FW) as a feedstock for an Anaerobic Digestion (AD) to produce the Methane (CH4) needed to launch Superheavy + Starship to orbit and beyond. The benefit of using FW as a fuel source may lower the cost per launch to SpaceX while providing a direct environmental benefit by reducing the global warming potential of the FW by diverting it from landfill (where the methane mostly escapes and traps heat in the atmosphere) to an AD feedstock for CH4 rocket fuel production.As I'm located in California and am most familiar with the regulatory situation here, as well as having access to good numbers for waste generation and composition here, I will use the City of Los Angeles as an example. Although I realize there are no current plans to launch Starship from Vandenburg, I think it's an interesting mental exercise and helps exemplify the sheer quantity of food waste and it's gas potential from a large city.<em>In short, there is enough FW generated in LA alone that is legally mandated to be diverted from landfill, but has no planned destination or processing capacity on the horizion, to power 65 Superheavy + Starship launches per year. That's one max propellant launch worth of CH4 every 5.6 days.</em>​WHY FOOD WASTE?Legal requirements for State to divert from landfillsReducing the amount of organic material sent to landfills is part of the AB 32 (California Global Warming Solutions Act of 2006) Scoping Plan, is fundamental to ARB’s Short Lived Climate Pollutant strategy and is one of California’s strategies for reaching the statewide 75 percent recycling goal. Collecting and processing organic materials, particularly food, is also the focus of AB 1826, which mandates such efforts beginning April 1, 2016. <a href="https://www.calrecycle.ca.gov/Organics/">https://www.calrecycle.ca.gov/Organics/</a>The waste sector aspects of SB 1383 ultimately require California to reduce the disposal of organic waste by 75 percent, and to recover 20 percent of edible food currently disposed, by 2025.

<b>Starship Structures - CSLM v0.3</b>
As always, a quick introduction before we get started. If you're new here or missed my previous posts, I'm a grad student studying Starship from a structural perspective. I have a relatively short background in this field, but enough to dive deeper. This project creates a "Loads Model" which is a very coarse model of an entire aircraft, used to determine the load distribution for detailed sizing in later phases of design. For more background info, see my previous posts linked at the bottom.(Also, I don't know the best way to embed pictures. My intent was to have them expandable with RES. Sometimes that seems to work, sometimes it doesn't...)​IntroductionWell it's taken longer than I would have liked, but I'm proud to say that I've completed most updates to the Community Starship Loads Model, and the it generally matches with everything we've seen in presentations and prototypes. First and foremost, some basic stats from this release:​AttributeValue (units vary)<strong>Dry Mass</strong>110t<strong>Length</strong>50m<strong>Diameter</strong>9m<strong>Number of Engines</strong>6 (3SL x 3Vac)<strong>Longitudinal CG</strong>33m<strong>Configuration</strong>Launch (All fins/flaps flat)<strong>Materials</strong>Isotropic 301 Stainless SteelOrthotropic 301 Stainless Steel Stiffened Panel (50%)<strong>Solve Time</strong>12.8s<strong>Loadcases</strong>100, "Launch Config, Full Prop, On Stack, No Crosswind"<strong>Results Quality</strong>Better than last time! Possibly Still questionable. Deformations look reasonable.<strong>Time Invested</strong>~60-80hrs (rough guess, I unfortunately didn't record any time tracking)MeshSo my last update was just prior to the big <a href="https://www.humanmars.net/2019/09/slides-from-spacex-starship-2019-update.html">Boca Chica Presentation</a>. Obviously there were a lot of changes to make! Let's take a look at the overall mesh for this release.<a href="https://imgur.com/BMPFOyx">Fig 1. FEM Top View</a>As you can see, we match the general profile and dimensions of the updated design. I've added internal structure for the tank domes, cargo bulkhead, thrust plate, and header tank (only 1 dome right now, perhaps the second one later). The header domes are something we haven't seen in the prototypes, but Elon mentioned moving it on twitter and in making it integral in Tim Dodd's interview (great job, Tim!). Also in Fig 1 you can see where the lateral CG falls (magenta line). The yellow lines represent beam elements (more on that later).Canards and fins have basic spars to close out the sides and split the planform (I think that's the word for it...?). They need more work to get some detail, but honestly it may not even be necessary now that landing loads go directly into the airframe.Speaking of which, I have no modeling of landing legs or attachments, but dat airframe doh...<a href="https://imgur.com/tkAHFg6">Fig 2. FEM Cross-Section View</a>In this shaded view you can see the internal structure again. If you look at the back, you can see a couple orange triangles. These are "lumped mass" elements representing the engines. Engines are layed out matching the 2019 Presentation slides (see link above). My Engine estimates are:​TypeMassX CG offsetSea Level (SL)2050kg0.5mVacuum (SL)2250kg0.625m​If you look closely, you can also see some struts I've created. These just help transfer that engine load more directly into the airframe. These are also beam elements, so mathematically they have a 2d cross-section, but model-wise they're just a line. This is advantageous because it allows more efficient computation with little loss of accuracy. I've used beam elements with varying cross-sections in places like the thrust bay and structural rings for the tanks. We can plot the cross-sections, <a href="https://imgur.com/p8qJULp">Fig 3. Methane Tank Rings</a>.​Let's take a closer look a the interstage and thrust structure. The dome is the Lower LOX dome.…
