Hmm. Shame your attention faltered before you read any of the available information, much easier to go for the video link I suppose, so you missed the cutting edge carbon composite shield with ceramic paint, Tungsten chips, Molybdenum alloy faraday cup and niobium wires in sapphire crystal tubes, and the fact that the deionised water is pressurised so the boiling point is 125 C, and the reason they use this is that water is better at handling the range of temperatures than most chemical coolants.
So quite a few technical triumphs.
