I don't know where you found this number, the commercial crew contract was awarded by NASA in September 2014 to SpaceX and Boeing (Boeing getting twice the amount of money than SpaceX). It was expected that two crew capsule would be certified by NASA in 2017.
SpaceX only certified the capsule Crew Dragon with a crewed launch in 2020, so 3 years delay. In the mean time NASA is still waiting for Boeing to do its first crewed Starliner launch.
There is plenty of reason to hate Musk but people at SpaceX did accomplish great things.
Without SpaceX NASA would still be relying on Soyuz to send astronauts to the ISS.
On the other hand I did took care of a pool for a while, it was in a villa that my in laws owned.
We did a few things that helped lowering the maintenance cost and the pool was pristine.
First thing is a salt chlorinator. It keeps a constant (low) chlorine level so the pool stays clean, there is no more chlorine smell and you only need to top up salt after too much rain.
Then we were using hardware store muriatic acid to bring the pH up and baking soda to control alkalinity. We still went to the pool store to get productd for the calcium hardness and cyanuric acid.
The last thing is a bit more involved but this is what made the biggest difference on the bill is to replace the pump with a DC pump directly connected to refurbished solar panels, no batteries, no inverter. This way when there is a lot of sun the pump is running a lot, a little sun and the pump is running a little.
It's perfect since the amount of algae development is proportional to the amount of sunlight. There is almost no electronic in the system, just a extremely reliable DC pump and solar panels that can last for decades, I found that to be a great low-tech solution.
However we were in a tropical country, I have no idea if this would apply in another climate.
For the first flight Starship left the launch pad, second flight it reached space, third flight it went to orbit (technically not completely) so hopefully for the fourth flight it will manage to reenter.
There is often cases where the first class offer exactly the same service as the second class, people are just paying extra to not be with poor people.
Is it really a drop in the bucket b when we take the value per vehicle ?
If we compare Ford to BYD for example.
In 2023 Ford sold around 2 millions cars and BYD around 3 millions.
For Ford only 72 608 cars out of these 2 millions were EV (3.6%) For BYD it's was almost 1.6 million EV (53.3%)
In 2023 Ford got $9.2 billions from the US government to produce EV, so around $126 000 per EV sold in 2023.
$126 000*1 600 000 = $2 trillions ! So unless BYD received more than $2 trillions dollars from the Chinese government in 2023 it means that each EV sold by Ford is more subsidized than an EV sold by BYD.
This is not an analysis, I took huge shortcuts in this comment and might have done mistakes in the calculations.
You can do that on the Prusa. The firmware let you cancel a part mid print but continue the rest.
