Adam Savage Reacts to Hacksmith's Newest Lightsaber!

Summary by Krater

Adam Savage visits James Hobson from Hacksmith Industries to look at the first retractable plasma-based lightsaber, discussing the engineering challenges of managing propane and oxygen flows, custom components, and thermal barriers.

From the video

Answers: How does Hacksmith Industries build a retractable plasma lightsaber?

• Retractable plasma lightsaber engineering
• Liquid oxygen and propane systems
• Class 100 cleanroom manufacturing
• Cryogenic cooling and thermal management
• Custom mechanical valve and nozzle design

What it concludes

• Building a liquid oxygen system for a plasma lightsaber requires a Class 100 cleanroom to prevent oxidation and catastrophic pressure failures.
• Liquid oxygen must be pre-chilled and the propane pre-heated to maintain a self-sustaining 3-foot plasma flame.
• The lightsaber's nozzle alone costs $3,000 due to its complex glass-blowing forge and machined brass disk construction.
• Uncooled liquid oxygen turns instantly into gas upon entering the system, requiring a precise pre-heating and fueling sequence.
• The cleanroom built by Hacksmith Industries exceeds the cleanliness standards of operating theaters used for open-heart surgery.
