"Will hydrogen overtake batteries in the race for zero-emission cars?"

TL;DR: No.

@davep There may be a use case for hydrogen, but it's not cars. See real world report here:

davep,

@withaveeay Potentially, for HGVs. But beware of the fossil fuel lobby and their Blue Hydrogen bullshit.

The initial article did mention rollout of EV HGVs, but that will always have a weight penalty unless there's a massive improvement in energy density.

Yay! Lost 19.5kg in 10 months.

I'll be releasing a book, provisionally titled "The Secret to Losing Weight By Not Drinking Industrial Quantities of Alcohol"

@simonzerafa No worries. I've had a couple of working lunches in the past week (in France) and it was easy to just decline the quasi-obligatory wine.

Not the first time this has happened with LinkedIn after I criticise that moron Jon*than Sc0tt on birdsite.

Baby steps installing my solar system...

Two SMA Sunny Boys to the left, two Sunny Islands to the right, and various protection devices, the AC Bus, and the grid connection with PE to local earth and grid neutral (TT) in the little box to the right.

Next step is to install the battery shelf on the floor and the conduit run below all the gubbins.

@davep Yes, but where is Jupiter?

davep,

@Penguinflight

Haha! I'll be "discovering" Jupiter when I replace the little box to the right with an automatic transfer switch (which I'm building with a friend) controlled by the master Sunny Island (all pole disconnect for the grid, but it gets more complicated for TN earthing as you also have to have contactors for switching between grid neutral and local earth).

It's for allowing both grid-tie with injection and battery backup when the grid fails.

An interesting approach to meat substitutes that has actually scaled. https://www.theguardian.com/world/2024/feb/11/spanish-startup-cocuus-pamplona-quest-3d-printed-meat-steak

simonzerafa,

@davep

Absolutely. But why does it have to look like meat?

Why not something different? 🙂🤷‍♂️

davep,

@simonzerafa It can look like whatever you want. The idea of looking and tasting like meat is pretty obvious, really. A lot of people just wouldn't countenance moving to a more plant-based diet.

Perun's latest video on the PLA is rather good https://youtu.be/ckouoTDkrtQ?feature=shared

tomasekeli,

@davep perun is consistently excellent

davep,

@tomasekeli Indeed!

Who could have thought 70 minute PowerPoint presentations on YouTube could be so fascinating?!

If the American deep state is so powerful, why is the dunderchief Putin asset still alive?

simonzerafa,

@davep

I have often wondered the same.

It's amazing how he has managed to survive long enough to make adulthood let alone become President.

A taxi driver picked up a nun. During the ride, he said to her: “I have a question for you, but I’m afraid it will upset you.”

The nun said, “My dear son, I have talked to all kinds of people in my life. I don’t think there is anything you can say that will upset me.”

“Well,” the driver said, “I’ve always had a fantasy of getting oral from a nun.”

The nun, a bit surprised, said, “That’s fine, my son. I might be able to help, but only if you aren’t married.”

The driver answered, I’m not married!” He pulled over and the nun delivered.

However, when he started driving again, the driver admitted, “I’m sorry, I lied, I am married.”

The nun replied, “That’s fine, my son. I haven’t been completely honest with you either – my name is actually Kevin and I’m going to a fancy dress party.”

Some percentage of those with this resistant strain will die.

So 30% of some unknown number of people with the drug resistant strain, apparently.

Seems to be single digit case so far.

So lots of issues here.

You can't do stats on samples of 1 or 2 and at no point do 60% of people die.

This so called article is borderline fake news.

davep,

@simonzerafa Still, I was fulfilling my doom quota (and only really read it after posting, I'll admit, and had the same "huh?" reaction you did).

My parents have 50 packets of Oxo cubes in their cupboard, I'm not sure they've got the hang of stock piling.
