| 0:00.0 | We've disconnected our financial system from our material system. |
| 0:04.6 | 70% of silver production comes from refining out of China. |
| 0:09.0 | The copper of lead and zinc that's mined in Peru and Chile is sent to China |
| 0:13.9 | and then a silver slag is taken out and sent to the ingot makers in Switzerland and Mexico. |
| 0:20.4 | What the Chinese have done is put a dual licensing |
| 0:24.2 | system, only 44 of the companies in China are allowed to actually sell it. And only approved |
| 0:31.5 | applicants can buy the silver. There's eight ton of silver in an AI data center. There's 65 ton of copper in an AI data center. You can go through the list. It's like a guillotine. If the Chinese want to turn the whole thing off, they can turn it off. |
| 0:48.5 | Welcome back to the Blockspace Pod, brought to you by CleanSpark. The United States data center, energy, and defense sectors are facing a multi-trillion |
| 0:56.1 | dollar logistics problem that almost nobody is talking about, except for today's guest, Craig |
| 1:01.5 | Tyndall. |

| 1:25.0 | of the refining capacity for the critical minerals and metals that are absolutely |
| 1:29.2 | essential for not just the AI boom, but also for energy systems across the United States |
| 1:34.8 | and critical defense systems. In this podcast, we break down how this transition happened, |
| 1:41.0 | how it was really allowed to happen is a better way to put it, and what it means |
| 1:45.0 | for the current AI boom in the U.S. and how it might end up derailing deployments and popping |
| 1:50.5 | the whole bubble altogether. This pod fuses a bunch of the topics that we talk about on the |
