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

TL;DR: No.

https://www.theguardian.com/business/2024/feb/13/will-hydrogen-overtake-batteries-in-the-race-for-zero-emission-cars

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"

davep,

@jan Cheers!

I got a Feelfit electronic scales with their associated app 👍

davep,

Although revealing the secret sauce in the title may be suboptimal 🤔

davep,

@simonzerafa 😁🙏

@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.

One from the archives. Still works.

davep,

@GossiTheDog Ok, I'll give this a go in the interests of science...

davep,

@GossiTheDog In the "About" section?

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.”

davep,

@siod Ah, thanks. I stole it from someone else...

Adults should be allowed to introduce ourselves to strangers like 5-year-olds do.

"Hi, I'm Lana. I'm 46 and a half. Do you have any friends? I like coffee and late-19th century Parisian classical music. You are really bald."

davep,

@Lana That is awesome 😅

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,

@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.

If you could pause body aging, what age would you have paused at, and why?

davep,

@RickiTarr
I'm nearly 58 and healthier than I've ever been since discovering the wonders of alcohol and cigarettes in my teens.

Stopping them was huge and I'd have liked to know how I'd have felt while still indestructible in my early twenties without testing the limits of my abilities to imbibe industrial quantities of both though.

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

davep,

@simonzerafa There is merit in both plant-based diets and the meat substitutes. The use of microbial (bacterial/fungal) sources with up to 80% protein and very little in the way of inputs could have a huge impact in reducing the amount of land used for agriculture.

The replica thing is most important for these bland microbial sources, and also for helping avowed carnivores to more readily accept moving away from a meat-based diet.

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

davep,

@tomasekeli Indeed!

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