Starship Update

Not the parent poster, but there is [0] Making Humans a Multiplanetary Species / Elon's original presentation from IAC 2016 - link [1] Starship Update / 2019 - ▶ this video

On Saturday, Elon Musk said that SpaceX will use direct air capture to make fuel from air on Earth: ▶ this video In partnership with Climeworks, one of the leading DAC companies, I just launched a campaign on Kickstarter using carbon materials to make a bracelet made of captured atmospheric carbon dioxide.

Climate change will create the first trillionaire. Find everything that eats fossil fuels and electrify it. Find everything that requires stable land and predictable weather and put it in a shipping container. Find every infrastructure investment that requires decades to pay off and decentralize it. Instead of water line pipes, pull water out of the air. Instead of copper and fiber optic cables on telephone poles, use solar and satellites. Instead of refrigerated transportation, grow food in your pocket or your stomach. Instead of roads, take to the air. We won't fix the climate out of kindness. Warren Buffet invested $$ Billions into wind farms because it makes his wallet feel better. Tim Cook just yesterday gave a speech that Apple said "We don't see climate change as risk, but opportunity", that's straight from the world's first trillion dollar company. [1] Elon Musk announced that SpaceX Starship will be pulling its fuel out of atmospheric carbon dioxide on Earth, and on Mars [2] We'll need to completely reinvent society. Sustainable transportation, vertical agriculture, solar/wind/nuclear energy, air mining, an all-electric economy. Topics: Direct Air Capture, making products out of atmospheric carbon dioxide, carbon removal. Check out all the companies in the space here: link [1] link [2] ▶ this video

Exactly. Elon Musk announced a few weeks ago that SpaceX Starship will be fueled from atmospheric carbon. They're building a process to pull carbon fuel out of the air on Earth -- and on Mars. Relevant quote on YouTube from Starship Update, queued up here: ▶ this video

> earth's gravity [..] right on the cusp of rocket flight possibility He didn't actually say that. He was talking about " rapidly reusable orbital rockets" and " fully reusable orbital rocket[s]" being the "critical breakthrough" that's necessary, the "holy grail of space" and the "fundamental thing that's required". So fully and rapidly reusable. ▶ this video

Sure, go to the video on Youtube [0], click the three dots menu on the right hand side below the video and open the transcript from there. This loads all of it at once, so you can even search through it with your browser's in-page search function! Clicking a line in the transcript jumps to the correct position in the video. It might be the most amazing feature that Youtube has. [0] ▶ this video

maybe , but that's also pretty unlikely. For reference here's where musk talks about it: ▶ this video No real indication he means a spiral. There are a lot of problems with a spiral. Thin sheets of steel, even hot rolled, are very affected by the rolling process. There's also the weld line going up in a spiral. That will cause uneven heat diffusion and expansion, which is a recipe for disaster given that the skin will be cold enough to liquify helium on one side and boiling hot on the other. Then red hot during reentry. Straight lines don't have the same problems.
