Plus your probably save on gas too.

The MG cyberster seems promising. I’m drivng the MG4 and I rely like the car.
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.
Falcon 9 is definitely manned.
The capsule Crew dragon, developed by Spacex for NASA, that flies on the Falcon 9 is the currently the only human rated orbital spacecraft in the US
The Falcon 9 is the safest rocket ever built, source.
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.
This was my criteria for buying a house : no pool !
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.
The argument of China subsidizing EV is always coming back but I would be curious to know the comparison with the US.
The US are subsidizing EV too I would not be surprised if the amount of subsidy per EV produced is much higher for US manufacturers than China.
Antoine de St Exupéry is a French aviator and writer who opened airmail route between Europe, Africa and South America.
One day he flew back from Africa to France with a Berber, someone who lived in the Sahara desert. As they flew through the Alps he saw all the waterfalls, lakes, streams, rivers …
At this point he told the St Exupéry that his the god of French people must love them more that their own god.
Most of French power plants are using evaporative cooling. Only 4 out of the 18 are rejecting water into the river.
Swiss green party might not like nuclear power but Switzerland is producing less than 30% of their electricity, the other 70% is imported from neighbors, mostly France.
Soooo they should probably be nice with their neighbors.
CF is extremely light, so when you want to build something that sink it make sense to build it out of extremely expensive CF rather than cheap steel like every other submarine.
I’ve added it at the end because it seemed obvious to me but yeah, insulation is the first thing to do. Especially under the roof.
There is a lot of passive system to prevent heat to come in, in the first place.
Airbus will share the market with Comac. Boeing will slowly sink into irrelevance.
This is why coworking spaces exist.
I don’t know in other countries but it is working quite well in France, you can get a subscription to the closest working space and have a desk, meeting rooms … To work remotely.
I like that it gives a separation between home and work but without long commute.
Energy in general is a huge geopolitical tool, see what happened with the Russian gas recently, most of the US military interventions in middle east are related to oil, France interference in Africa to secure uranium mining …
Renewable energy is just another energy, the advantage of renewable energy is that the energy source is kinda well distributed around the world.
Yeah, last time I’ve rented a car I wanted an electric but my insurance would not cover me for a Tesla.
They are in the sport car category.
It’s not like the front of the plane fell off, which is obviously not safe.
I’m doing that and generally the next step after that is : “OK, can you do it again and this time DO NOT CLOSE THE ERROR POPUP so we can get information on what is happening”
