It was recently announced.

At 60% efficient, it would be about the most efficient ICE engines ever. So it is worth a look. And yes, people do like noise.

It takes the same amount of electricity in theory. Even in practice it is not a major issue since an all renewable grid needs energy storage, such as hydrogen based energy storage.

There are tens of thousands of FCEVs out there. It’s enough to know it is safe.

BEV charging infrastructure is repeatedly brought up as the major sticking point. BEV fans have handwaved away the real challenges to their own detriment.

It would probably still suck if that happened in the tunnel or underground garage where it doesn’t disperse fast enough.

A very rare scenario. You would need a large quantity of hydrogen leaked in a short period of time for this to be an issue. In reality, this is highly unlikely and should not be something we worry about. Meanwhile, thousands of people die in gasoline fires all the time.

There’s basically no leakage in a type IV pressure tank. People have repeatedly tested them and found negligible escaped hydrogen.

You are far safer in a hydrogen car than a gasoline car. Hydrogen floats away rather than pools underneath the car. No one has ever died in a hydrogen car fire.

A battery has far more thermal energy than a comparable hydrogen tank. In fact, there have been BEV explosions and fires, and many people have died. All evidence suggest that this is a greater than danger than comparable risk of hydrogen fires.

Hydrogen can be stored in pure form. Pressurized hydrogen in tanks or underground salt caverns is fully possible.

Unless Europe suddenly changes its mind and goes hard in favor of nuclear, it has no choice. It will have to invest heavily in hydrogen or admit that they will always be using fossil fuels.

The two-car FLIRT-H2 can seat 108 passengers over two cars with a power pack in the middle.

It’s also a train, so you can easily add more carts.

A hydrogen-base system would get much cheaper per kWh as it scales up. Most of the cost is probably the fuel cell, electrolyzer, batteries, etc. The tanks probably cost very little.

This study is based on a household in Spain. Different countries will probably need different setups.

So many instances block Hexbear and others. We are well on the path of creating separated communities, just with the added headache of having to police federation. Not to mention the problem of power users and out-of-control mods, which federation makes worse rather than solving them.

Ultimately, I think a real Reddit replacement will have to think hard about fixing the fundamental problems of this form of social media, rather than attempting to use buzzwords or cool new ideas.

Federation makes sense for a Twitter replacement. Not so much for a Reddit replacement. I get the feeling that we are at an end to the experiment. Eventually, people will realize that we cannot replace Reddit with a Fediverse based solution.

The Harris poll is garbage: https://www.thecrimson.com/column/forging-harvards-future/article/2024/3/26/bodnick-/

They’re quietly removing all such accounts. They won’t even allow accounts without email addresses anymore.

It’s why Google is secretly in big trouble. Their biggest and most successful ideas were from well over a decade ago. There’s very little real innovation going on at Google now. They’re just throwing crap at a wall and hoping something sticks. Eventually, their cash cows will dry up and they won’t have anything to fall back on.

This is also known as “Libertarian Socialism.” Interestingly enough, this idea predates the current definition of Libertarianism by decades.

Fuel cells have the potential to help overcome the challenges associated with Battery Electric Vehicles (BEV), namely a dependency on limited natural resources, electric grid capacity, battery charging time and vehicle range. Fuel cells can also be as cheap to manufacture as internal combustion engines and can be produced using recycled and recyclable materials.

Reminder that fuel cells are less dependent on resources than batteries, can be about as cheap as ICEs to make, and can be made out of recycled materials.

It’s not a combustion engine. It’s a fuel cell.

The car in the article is a PHEV. It can do the same thing.

Public fast charging is the same experience as a filling station. Except it takes longer.
