    Personally, outside of some niche applications, I don’t think fuel cells are going to replace EVs. The losses in efficiency are just to great in the conversion from water to hydrogen/oxygen gasses to electricity - unless someone figures out how to harness the energy released in a hydrogen bomb. But I wouldn’t hold my breath for that. I do think that Tesla isn’t as long for this world as Musk would have hoped for though. I personally hope he ends up broke and mocked as soon as possible. The world will be just a tiny bit better place IMO.

    An interesting article about the Muskmelon, Tesla, and fuel cells. []https://energynews.biz/will-tesla-release-hydrogen-car/ (take the article with a spoonful of salt I think) It’s perhaps another attempt at a pump and dump stock fraud as he does need money for twitter. But, I’ve seen a couple of these blurbs lately and I can’t find where they originate from.

    Even the ketamine wonder wants to sound like he thinks Tesla is going to abandon pure EVs and build and sell something with a hydrogen fuel cell evidently. If so,and you can’t rule out it out completely yet, the ICE engine might not be done yet - just swapping a fuel source.





  • Most pets don’t work because their owners don’t bother to train them to do any work. And interestingly enough, I have indeed seen a Chihuahua herd cattle. There was No Fear. It was amazing to see that little toothed monster chase a 2000lbs bull around a pen and into another and then into a barn on command from the farmer that owned him. And a Mastiff will gladly hunt fox, cougars, wolves, and even people if you want them to. They will also happily Netflix, popcorn, and chill on the couch with you after chewing up that human also.

    Why don’t my dogs talk? Well, they just don’t have the physical voice box to form the sounds of human speech, (as you well know). But that doesn’t mean they don’t communicate with people. Actions, like tail wagging, barking in various tones and volumes, rolling on the ground all communicate emotions and situational reports. And us humans understand them just fine. My little Russian Spaniel does her best to “talk” to me with a near continuous stream of moans and groans, and erffs when she sits with me in my recliner. It’s almost annoying when she doesn’t shut up. And they understand my communications. My dogs understand verbal, whistle, and silent hand signals and respond correctly and instantly to them when I’m afield with them. Parrots, have a natural physical ability to mimic other sounds, (as do a lot of other birds). So they are doing what comes naturally to them - a human is not required.

    There are lots of dogs out there that do jobs they were never bred for. Seeing eye dogs, dogs trained for deaf people or assistants to people confined to a wheel chair. Turns out Labrador Retrievers are really great at this kind of work. And I have trained retired Springer Spaniel hunting dogs to work in a hospital as therapy dogs. But that’s not why or what those breeds exists for. Ever see a trained animal act at a circus? They are often what most people would call “mutts”. Mixed breed dogs doing amusing things like ride bicycles and drive little cars around and jumping through burning hoops of fire. And you can often see little Chihuahuas preforming in those acts. All doing things none of them were bred for.

    I like the cats that we have. One, a grey and white is an excellent mouser. But he comes from a very long line of barn cats and has a wild streak in him. The other two, are far more interested in cat toys and sleeping in laps and beds than in any mouse - and that’s fine. A warm kitty in the lap purring away is a calming and enjoyable thing to have on a cold winter’s day. But I’m under no illusion that cats or most other pets can be trained to do all the things my dogs can do.

    Dogs are humans oldest and closest companions and co-workers for a reason.




  • I’m not an architect, but I have stayed at a Holiday Inn.

    The easiest way to think about an element being “structural” or not is is to consider what can happen if you remove that element - will the roof/wall collapse on top of you or not. If the answer is no, the roof/wall will not fall down, it’s not “Structural” or “Load Bearing” If the roof/wall can fall down on if you remove it, it is “structural” or “load bearing”.

    So, using your example, if you were to remove the drywall and furring strips from that cement block wall, will the wall and ceiling be in danger of collapse? If it is, then it was structural. If not, then it wasn’t structural.

    The Architects and Civil Engineers that I have known, do not consider drywall or furring strips to “structural” when designing a building. I’m going with their consensus on this matter.
