Nah. They get contract for mining on Mars, valued north of $1T.

there was an article recently about a company wanting to put nuclear reactors at the bottom of very deep boreholes (like km deep).

I thought that was actually quite interesting/practical, because if there is a problem, you can just bury the problem.

not like tmi/fukushima/chernobyl

Interesting idea. 2km deep could work. I'm not sure how cooling or maintenance would work.

Depth below surface | Typical temperature (°C) | Indicative cost to drill 1.2 m diameter hole

500 m | 15–25 | $5–10 million

1 km | 25–40 | $10–20 million

2 km | 50–70 | $25–45 million

3 km | 75–100 | $50–80 million

4 km | 100–130 | $90–140 million

5 km | 130–160 | $150–250 million
