When you still shudder every time when you see an URL or directory ending with .com and think for several seconds before pressing it.
I do.
Also an age detector.
It could be frozen in a normal matter matrix, to make the atomic motion slow, and the contacts between the particles rare.
So, it will be slowly annihilating and releasing heat, but to prevent its warming from that heat, the whole thing should be enormously huge, and at the same time having low overall energy production rate.
He's provided with money and time. The money is unlimited, the time isn't. As he's enough young, probably some deadline is coming.

Btw, how many SH/SS successful launches ( * 40 successful ignitions for one-way flight) is required for one lunar expedition?..
Your raspberry pie, sir. Its taste is a little plastic and you should spit out the golden contacts, but the natural berries have too low critical mass to put them in a pie.
Bartender! The free shot for the first client today. See, he's coming in, don't miss.
Because the modern trains operate with by orders of magnitude lower energies and temperatures, easily containable in a small metal jar.
The external combustion is maybe the least efficient, but the only available way to keep your train solid when the equilibrium temperature of the energy source means it being plasma.
Orion doesn't need a solid structure around the reaction zone. And that's the only reason why it's the only viable within the known physics.
... and when TikTok had been banned, they realised that the nuclear submarine communication network is crashed, because navy officers were using it instead of slow and boring infra low frequencies, by tying a Huawei phone to the periscope...
