The use of a fuel to make a means to push the rocket is similar to dropping a stage after use.
The Astronautix site also contains lots of history of the engines that have been used.
Normal engines out during the flight path is expected to be done to save fuel and capability for the unexpected. But not normal is when an engine fails such as the 1 did on the BFR stage. One can only turn on normal off engines when you have extra engines to do so which could be done on the starship during the landing if required.
Seems that based on the heat getting into the wing would call for design changes and other testing flights.
Money for the https://en.wikipedia.org/wiki/Intuitive_Machines_Nova-C was designed by Intuitive Machines (IM) to deliver small payloads to the surface of the Moon. Withe the seed money coming from Nasa to deliver to the moon but under contract it did do that. With no money coming from outside of the US from what I can tell.
Using the opinion words from some twitter content might not be the best choice and then change or conflating to another failed craft not related also makes for off topic content. Comparing cost to another off topic would also be outside of the scope of the topic.
As an Admin part of my role is to direct Net Etiquette or NewMars forum Rules such as they are from its beginning. Now I am being off topic to give the reminder. I am sure there are more such moderation of content rules and that is why we have as many Admin's and mod's as we do.

Keep in mind that off topic content is not wanted or warranted in a post. I do try to be fair with post content and consider the members standing when making choices to amend, or to move post content. This is what also is expected by all of the other Admin and Moderators of the forum.
That can only mean that someone has your log in information.

Seems more structural mass will be taken from the payload that it might one day show that it can haul to orbit.
We have the inverse in the Pacific as China is building the rocks into bigger pieces of property.
Other money-making is through property insurance guard for the wall that is built. Surveying of lots to know where it can be built. Waterway rights of the land that resides within its reach but also from the standpoint of law.
update:
The company that builds the wall would want to get interest so they would also want to do insurance so as to prove that they are behind their product that they build.
Over build the wall to meet the 500 years high and there should not be any failure.
First other than Nasa data no one is viewing or monitoring with measurements for places that need help now. Other than the news story that near ocean loss of property we never hear anything until it's too late to put a plan into motion that would save them.
Reminds me of the slow glass topic....
https://en.wikipedia.org/wiki/Equations_of_motion
Ship mass = 200,000 kg
5 (9.8M/s) = 49 m/s^2
Force = 9,800,000 N
2*d/t^2=a
2*1Km/ 49 m = 6.38874 sec

update the * is the multiple in the equation.
Since you have waves crashing against the walls that are built why not use it to do the energy creation.
Also, all of the estuaries with the tidal water can spin turbines in each direction of the water flow every day as another method.
It is an art to solve problems as now a location that fits the model with alteration.
It means a carrier sled with or without wheels.
Electrified with a tremendous level of power with each use in a short period of time.
It's one of the reasons that they stopped going towards the electrical due to component breakdown.

Seems that BE-4 engine and the Raptor are coming up quite strong.

In a while we may not how much more stable it will be.
A recent report highlights that since 2010, the Gulf of Mexico has seen sea levels rise at twice the global average rate. Tide gauges from Texas to North Carolina show sea levels at least six inches higher than 14 years ago.
What is the Length of the US Coastline?
The National Oceanic and Atmospheric Association (NOAA), for example, took a measurement of all the United States coastlines in 1939-40 and again in 1970. They surmised that the total length of the combined US coastlines amounted to approximately 95,471 miles.
This measurement took all US territories and their borders with water into consideration, including Hawaii and Alaska, as well as other Pacific and Carribean islands.

Yes, since I have worked with fiber optic cable making where the jacket of Kevlar fibers is thread like materials, but it's still needs to be woven and then stretched over a frame to make it not sag.
1 gallon of water a day per person and then food and oxygen must be supplied for the duration that seems like it could go nearly a week.

Seems that the engine running on the RP/Lox are all about the same even the Russian models that we are building a replacement for.
Seems even methane / lox is not all that much better.
Handed over to the space force while the other version went into the dumpster of time.
We know that the composite tank for the starship was fully tested, and it seemed to hold up plus even did a burst test at sea from what I recall.
From launch to docking, a spacecraft typically takes between 6 hours and 3 days to travel from Earth to the International Space Station.
Seems we need to plan for the worst of the times both up and down.
