The stats are pretty out there. Iirc just the fuel pump, which you can probably pick up and put on your desk, generates 100k HP.
Well, it's powered by bleeding exhaust from a very big rocket.
My hope is that Flight 12 goes nearly flawlessly (at least gets to soft splashdown) and they can start testing in-space refueling in July/August.
If they can demonstrate in-space refueling by the end of 2026, then they have a shot at a lunar-landing demo in 2027 and a crewed-landing in 2028. But a lot has to go right for that to happen. Here's hoping it does.

Superheavy is 10x larger than the Falcon. Its thrust would sink the barge.
Yeah. Rocket first stage Approx. unfueled mass: Super Heavy: 200000 to 280000 kg Falcon 9 first stage (without Falcon Heavy side boosters): 25600 kg
There is a lot riding on V3. SpaceX cannot afford to take too many launches to get V3 solid. If 2026 is another 2025 (3 V2 failures in a row followed by 2 V3 successes), then they can forget about landing on the moon before 2030.

question: what will happen if orbit refuelling goes wrong? Won't it destroy everything in orbit?
No. What is the mechanism through which you suspected this could happen?

There could be some odd failure modes I would think. Failure to pump the liquid, broken pumps, who really knows? My guess would be that a failure mode would be a big spill, a failure to pump, only partially refilling, or broken turbopumps before an explosion.
