Miner revenue consists of (1) the "coinbase" per-block reward, and (2) fees per transaction.
Transactions fees are growing and eventually will be the only source of miner revenue.
Depending on the demand for on-chain transactions, some miners may have to shutdown. The
remaining miners will then get more revenue. Supply and demand.

Saturn V is sadly not available today.
Anyway it was more expensive and less capable than Starship.

What about the non-intensive purposes ?

Perhaps you meant "intents and purposes".

Reference please.

The bitcoin transaction fee is about $1 recently. So any transaction over about $33 will have lower fee on bitcoin than on visa.

A fair comparison of bitcoin to visa must acknowledge that visa has over 20,000 employees.

The energy use of bitcoin is trending downward. The block reward (coinbase) is diminishing and soon there will be only transaction fees to support the miners. There won't be enough in transaction fees to support all the current miners and some will retire. Also, more and more of transactions are being handled by second layer protocols, such as lightning, or off-chain inside of exchanges. These transactions consume much less energy.

You're wrong.

Glaciers are a 3d structure. It is volume of ice that matters, not surface area. Satellite photos provide 2d data, which has to be interpreted through a model to estimate volume. It would be much better to have direct measurement of ice volume. So NASA developed the GRACE satellites, which use gravity anomalies to measure the mass of the ice in glaciers.

Sadly, for the fearmongers, the data did not support their message. GRACE showed that total volume of glacial ice is stable.

So the GRACE data is being ignored, and unverifiable models are being applied to photos again to generate fear.

Parachutes are perceived to be more reliable than a propulsive landing. So the small tough capsule with humans has parachutes. It can survive banging into the ground and rolling over.

The large fragile booster does a gentle propulsive landing.

Unbelievably lame. There is no such unit as a "gigawatt per hour".

You can't even be sure what this means, if anything.

The NSA should hire the SCTO (secret chem trail organization) to handle their security. No more leaks to worry about. Show the NSA how to control information right.

It is clear that the SCTO maintains a global fleet of thousands of specially modified tanker aircraft for 24/7 operations. There is a small army of technicians, mechanics and pilots. They skillfully manage extreme logistical challenges to safely manufacture, store, and distribute all the millions of tons of chemicals. All in secret. Not one whistle-blower. Not one crash or chemical spill. Not one photo or chemical sample has leaked.
