Comment Re:Temu missiles (Score 1) 312

Reaching hypersonic speeds and hitting the ground is not that particularly hard. ;) Hitting the target and maneuvering that's where challenge is. However if you can cast the "meteor shower" upon your enemy, single missile accuracy is no longer a big issue. When number is high enough it becomes a quality of it's own. This is the reason Israel is worrying about Iran's ballistics as you cannot shoot down ballistic missile the same way as drone or cruise missile, where you just explode an interceptor somewhere near by and let fragments do it's job. You have to DIRECTY hit a relatively small target travelling down at multiple kilometers per second. And yes, almost every ballistic missile is a hypersonic missile at certain trajectory stage. ;)

You get what you pay for. "using civilian-grade materials and widely available commercial parts, along with simpler manufacturing methods like die-casting" I'm sure these will work reliably. Why didn't lockheed martin think of that?

If you can make 100 missiles with civilian grade materials for a price of 1 missile with military grade materials, then the choice is obvious. Even with failure rate of 50 percent that would mean a total overload of any missile interception system. Just launch them in 100 batches. Especially when launch subsystem is not an issue too. ;)

And what that would prove? The fact that battery is drained faster due to petrol has ~100 times energy density by weight than battery is nothing new. This is known for a long time. And if you look at drag race (which I would not call a race at all), EVs humiliate V8s and V12s with ease. EVs are good and by most of the parameters they are better than ICE. They still have two serious issues: substantially higher price and lack of convenient charging infrastructure in lots of places. Longer time to charge can be almost completely avoided if proper infrastructure is in place and EV can be charged every time vehicle is not needed.

You're absolutely right - gas engines aren't necessary, and frankly they're silly.

Unless you don't have a garage on hour house, live in a house built before 1980, or live in an apartment. Then you're SOL. There's no infrastructure for you to have an EV.

Excuse me, but since when apartments have a build in petrol/diesel station? So "no infrastructure to have ICE" too. ;) I would agree on statement that it might be less convenient - true. I would like various charging options to be available at shopping centers, restaurants, work offices. All such facilities have more or less capable power lines and vehicles are left unused there for a prolonged time. So that should be the solution for convenient charging for apartment dwellers.

Reality check: Petrol/gasolene cars produce very little NOx. It is mostly a diesel engine problem and EVs mostly replace petrol/gasoline cars.

Reality check: an old clunker, bought for 1500-3000$ that still runs from the last century, has no catalytic converter anymore and nobody will bother to replace it... You might be surprised what emissions are for those engines. And if it does have a turbine, then NOx emissions skyrockets.

Public transportation just isn't practical in a huge mostly-rural country. Sure, you can create public transit in urban/suburban areas. People who feel so inclined are free to use those options. They are typically poorly managed, dirty, crime ridden, and not particularly popular with people who have no other option than to consume those services.

I can see how it is much easier to implement in smaller countries with significantly higher concentrations of people in smaller areas.

And that is explicitly what is meant by "ending car dependency". Have the viable alternative to the car. If public transport is usable, then why drive car? I agree that it might not be feasible for rural regions with 1 person per sq.m. But for more densely populated rural regions it is a viable solution. But it requires investment and proper city planning, which sucks in US/Canada, where everything is designed to be only usable by car.

You seems to be confusing "making a copy for private backup purposes" with "making copy for a friend". These are slightly different use cases. ;) From the Wiki page below: "A common misconception is that levies are compensation for illegal copying such as file sharing. This is incorrect, however, levies are only intended to compensate for private copying that is legally allowed in many jurisdictions." However that does not mean I am in favor of those restrictive copyright laws, no the contrary... Arrr, Arrgh, Yarr, Gar ... Where's my tricorne... :D

When I was young or a young adult, both the young and the old were copying music and videos (reel-to-reel or cassette tapes, VHS cassettes) for personal use among friends and the wider family all day long. Actually, in many jurisdictions, like the one where I grew up right in the middle of capitalist Europe, it was perfectly legal, too. And what do you know – movies and music records and concerts kept coming in nonetheless. Because, by tendency, many of those who were the biggest sharers were also the biggest buyers. There also were sensible flat surcharges on tapes and cassettes and recording equipment which were distributed among artists.

Anyway, I also seriously question today's movie industry. Can any movie be worth hundreds of millions of dollars? Are hundreds of millions of dollars, the least of which, by the way, find their way to the ground personnel in such productions, well spent in making a movie, of all things? I, for one, don't think so.

No it wasn't legal at any time. It was just not enforced heavily as people were still buying records and it required physical interaction to make EACH copy. However when digital copying became possible, record industry became really scared. ;) Regarding costs, yes, they are overblown. In part due to inflation too. But making those lifelike visual effects takes time and effort and that needs money to pay for expertise and resources. Plus actor payments also have been inflated to the high orbit...

"2025 mileage rates Self-employed and business: 70 cents/mile"

??? Does that include all the car maintenance and insurance. But still that is almost 2x more expensive than using car sharing service around here, which provides cars for rent for prices from 25 cents/km. And this is in Europe, where fuel is 1.5-2 €/l.
And if that's just fuel, than it is insane... I am paying 5-10 ct/km for my current PHEV, which is quite thirsty for fuel.

There is a big problem for the country when automotive sector, which provides ~20 percent income, suddenly goes bankrupt. So even if they would not ask, government would try to bailout them. Main problem: automakers are expecting that they would be able to continue the same way they have done in past 30-40 years after bailout.
