My favourite thing ever seen in source code was a comment that read “this code is temporary” with developer initials and a date that was at the time about 5 years ago.

Followed by another dated comment from about 3 years later that read “Temporary my ass”

😂

No.

MW is the maximum capacity not the average.

A nuclear reactor runs at close to its maximum output pretty much 24/7/365.

A solar farm only operates during the day, and even then it only operates at maximum output in the middle of a clear sunny day.

The overall average output of a nuclear plant is typically around 90% of its capacity.

The overall average output of solar farm is 20-25%.

This massive farm will still only output a bit more electricity than what a single nuclear reactor outputs.

A nuclear power station typically has more than one reactor, so compared to a typical nuclear power station this isn’t even close to the average nuclear plant.

Though it does beat a few of the smallest nuclear plants that only have a single reactor.

Nuclear outputs a fuck-ton of electricity for its size.

Sandford Fleming (the guy who invented time zones) actually made it easier.

Before timezones, every town had their own clock that defined the time for their town and was loosely set such that “noon is when the sun is at its highest point in the sky.” Which couldn’t be measured all that accurately.

If it wasn’t for Fleming, we’d be dealing with every city or town having a separate time zone.

Yes you’re correct. I will qualify my previous statement as hydrogen powered road vehicles don’t make sense for now.

The problem at the moment is that electricity generation is not carbon free and in most countries not even close.

Unfortunately the transition to a carbon free electric grid is being significantly retarded by policymakers that are, as you say, myopic. As a result it will be at least two more decades before hydrogen makes sense.

The carbon footprint of lithium battery manufacturing, is small compared to the carbon footprint of electricity generation. Until that changes significantly lithium batteries will continue to be a better choice than hydrogen fuel cell.

Hydrogen may make sense in a future where we’ve eliminated all fossil fuel electricity generation and there’s an abundance of carbon free electricity that can be used to create green hydrogen as a form of energy storage. Though by the time that point comes, we may have developed battery technology or some other energy storage technology that doesn’t carry the same carbon footprint that lithium ion does today.

Hydrogen doesn’t make sense and never did as a strategy to reduce greenhouse gas emissions in vehicles.

Most hydrogen is made from fossil fuels, and has a lot of emissions during manufacturing. But even green hydrogen, which is made by using carbon free generated electricity to split water into hydrogen and oxygen doesn’t make sense.

If you’ve build new renewable power it’s more efficient to use it to charge batteries than to use it to generate hydrogen.

There might be a case for compressed hydrogen, In vehicles where batteries are too heavy like aircraft.

But for road vehicles, batteries are more effective at reducing emission.

If you’re building any new renewable power, you’ll reduce more emissions by using it to displace coal power, the to generate green hydrogen.

Some day when we’ve eliminated fossil fuel based electricity generation, Green hydrogen might start to make sense. But anybody trying to do it right now is not being as helpful as they could be.

Stated goals of the UN charter according Wikipedia:

to maintain international peace and security, uphold international law, achieve “higher standards of living” for their citizens, address “economic, social, health, and related problems”, and promote "universal respect for, and observance of, human rights and fundamental freedoms for all without distinction as to race, sex, language, or religion.

Did they even read the charter before having their little temper tantrum?

If a website using home realm discovery adds anything more than one extra press of the enter key or mouse click of an ‘ok’ button, get a better password manager.

If you’re annoyed by that one extra click that’s fair. Click counts matter.

It’s called home realm discovery. It’s common in business apps though it’s usually used with email & password logins not username & password logins.

It’s done that way to support federated logins. Larger companies will often used a single sign on solution like Okta or Azure AD. Once the user’s email address is entered it checks the domain against a list of sign on providers for each domain and redirects the user to their company’s federated login if it finds it there instead of prompting for a password.

This has several benefits:

1. The user doesn’t have mutiple passwords to remember for different apps. Which is know to result in users either reusing passwords or writing down passwords somewhere.

2. When an employee quits or is terminated the company only needs to disable their account in their company directory and not go into potential dozens of separate web apps to disable accounts.

3. The software vendor never receives the password, if the vendor’s system is compromised they don’t even have password hashes to leak. (Let alone plain text or reversibly encrypted passwords)

Websites that work that way are (usually) doing it right. If that doesn’t work with your password manager, you should (probably) blame the password manager not the website.

The challenge with green hydrogen is it needs to be created using green electricity. If the electricity isn’t green you’re still burning fossil fuels to create it. Creating hydrogen from fossil fuel generated electricity and then burning it is less efficient than just burning fossil fuels directly and results in a net increase not decrease in carbon emissions.

As we build additional green electricity generation, it’s currently more impactful to use that to lower grid demand on fossil fuel generated electricity than to use it make green hydrogen. If it’s used to make green hydrogen instead, we’re only delaying the day we finally eliminate fossil fuel electricity generation, which again benefits the fossil fuel industry.

Only at some point in the future, when we’ve completely eliminated fossil fuels from the electric grid, and have created an excess of green electricity generation does green hydrogen even become possible to create.

And even assuming we can achieve that some day. It’s less efficient to use electricity to create hydrogen to power vehicle than to use batteries. Anything that can be converted to connect to the grid directly or run on batteries is better doing that than running on hydrogen.

It’s not completely crazy… there are some potential use cases for green hydrogen that would make sense in some theoretical future where there’s an abundance of green electricity generation, allowing replacing of fossil fuels where more direct forms of electrification isn’t viable. Aircraft in particular come to mind here since hydrogen stores much more energy per kg than batteries, which are currently too heavy to be viable in aircraft.

But almost all promotion of hydrogen today, including green hydrogen, is either more greenwashing by the fossil fuel industry or the work of well meaning idealists that have unwittingly become their shills.

Green Hydrogen is not a solution for the vast majority of things it gets presented as a solution to.
