Dissecting a V2 rocket steam pot

We continue exploring the A4 / V2 rocket in detail, and in this video, we dissect a real steam generator used to drive the missile's steam-powered turbopumps. The relic was discovered in Germany a few years ago and recovered from a ground excavation in a very rusted condition. We look briefly at some operations to preserve the relic and prepare it as an educational exhibit. Robert looks at the construction, exploring the history and details of its function along the way.

I hope when you've seen the unique content of this video, you might feel inspired to help us research and produce videos like this one and become a channel supporter via our Patreon platform. We have a growing number of benefits to reward Patreons, including unique content and early access to ad-free versions of our latest videos.

I don't expect rich rewards for this effort—for me, it's a labour of love. But costs are high, and I receive assistance from others that must be funded. Lack of funding is restricting our progress and making production slow and more challenging than it needs to be.
