So the question is whether to spend the capital dollars on a plant to turn electricity into fuel, or spend those same capital dollars converting or replace the internal combustion engine with batteries and an electric motor. They have a long way to go to make the economics of this air+electricity to fuel machine a better choice than converting to batteries and electric.

It doesn't matter if you use water to cool in a closed loop system. The problem is only if you're using fresh water and just heating it up and dumping it and pulling in more fresh water.

So in this case, it's completely irrelevant.

You have to build the solar panels which don't come from thin air.

Also, it likely ISN'T being done from solar/wind/hydro. That's the problem with lots of these "green" things is they just hide the problem behind dirty power sources. Hydrogen is a great example.

a TON of electricity that doesn't come out of thin air.

Click bait BS.

William Shatner is a classically trained Shakespearean actor who appeared in festivals and on Broadway prior to switching from stage to television. His TOS enunciation and emphasis is due mostly to his experience with radio performances (which were over the top verbally) combined with directors on TOS constantly telling him to increase the astonishment. And in reality, wasn't anywhere near as pervasive or dramatic as the pop culture version that pokes fun at Kirk.

If there's a "theorum" about that, they'll find it eventually.

FFS, the summary has a link to https://en.wikipedia.org/wiki/... named "Star of David theorum". Ever heard of copy-paste, or does that need an LLM these days?

What are the national security implications for the USA if Canadians regularly cross the border in to the US while driving their Sino-EV?

The US is paranoid enough to have banned DJI drones (in fact *all* foreign drones) on the grounds of "national security" because they could photograph sensitive locations -- but then again, couldn't a Sino-EV with its plethora of onboard cameras. Given that these Sino-EVs are going to be "chatting" back to their Chinese manufacturers, how are we to know that they won't be dumping screeds of sensitive image data right into the hands of the CCP?

Inquiring minds wish to know.

Anyone wanting to build a gun really only needs some basic metal-working handtools and
set of plans.

I know I'd much rather have a Sten gun than a 3d-printed "one time use/explode" one.

3 MPH is a quite brisk walk. 8 mph is a 7.5 minute mile. Most people can't run one mile that fast much less a bunch in a row.

I agree... I would really love to have a system setting that said "No shorts, ever, anywhere on the platform" but we must be grateful for the fact that it's only taken how many years for YT to finally listen to those of us who've been screaming for today's enhancement?

As others have said... now it's time for a "No AI" filter but unfortunately YT doesn't ask uploaders whether their video is AI generated or not -- it asks far more vague questions that also require anyone who uses VFX (such as almost any modern feature or indie movie) to tag their uploads as "altered content". Why is that?

My sister-in-law just traded in her Fiat 500 for a Hyundai Tucson. Because she and my brother were in an accident (not their fault) in my brother's bigger car, and is still recovering from her injuries. I fully understand. But I'll be driving my 2200 lb convertible as soon as the snow and salt is gone.

"High Speed Rail" has been defined as 85 MPH, and it's regulatory, more than practical. If you run your trains at more than 85 MPH, you have to update all your grade crossings so that they put the gates down a constant time from the train arriving at the crossing, rather than a constant distance. Steam trains would exceed 85 MPH at times in the 19th century. I believe the record is above 100 mph.

Who says I didn't have the money to do so? I didn't go into that at all. But since you're curious I'll explain: Yes I had the money to buy one outright, but an interest-free loan was available and I took advantage of it. Had I purchased it outright, then had an expense outside of that like a car-repair, THAT would have had to come out of my interest-charging credit card and ... while I didn't actually check on it, I'm pretty sure Apple/Goldman would not have given me a similar payment plan for the car repair.

I went to an Apple Store purchase an iPad with an Apple Card last year, I wanted to take advantage of paying it off within a year no interest. At the moment of checkout Goldman declined me and wouldn't tell me why. After two days and several scattered phone calls they claimed that it was unusual activity on my account. I pointed out to them that I had successfully purchased and paid off 3 other items on the same payment plan, and that their assertion that my activity was unusual was absurd.

I'll spare you the blow by blow because I know it's boring, but ultimately Goldman Sachs held to their position that they did the right thing, and Apple had to come to the rescue. They talked to each other a bit and I finally got my device on the payment plan I wanted.

I'm greatly looking forward to Goldman getting out of the picture. They really did try to spin it to me like the inconvenience they caused me was somehow something I should be happy about. "This happens because we're diligent about catching fraud!" "But, you didn't."

But do NPUs lock you into doing AI? After the AI bubble bursts, your CUDA/Nvidia hardware can be used for other things. While I prefer more open solutions such as OpenCL on AMD, the same OpenCL code will also run on Nvidia hardware.

I don't know about the details of NPUs, but I've got the impression that efficient AI uses very low precision arithmetic, such as 8-bit and even lower. So while it could be possible to use NPUs for general vector/matrix math, the low precision would be a deal breaker for a lot of applications.
