Comment Does not US have something like registered mail? (Score 1) 179

Besides the fact that US still writes and accepts bank checks and requires signature on a cashier check after credit card payment (mine cards does not even have place to put a written signature to compare for last 10 years) it sound strange that financial documents are sent via regular mail. Does not US post office have a registered mail service? In my home country and AFAIK across all Europe you can register your mail item and post office ensures it is delivered to recipient, they take additional fee to ensure that.

Those three statements are policy choices, not objective facts. Capitalists like to present them as inevitable, but of course they are not; they are only presented as such because it's in capitalists' interest for people to see them that way.

If you look back at socialist statements, you would see more or less the same, minus sell for profit. ;) However for some reason all socialist countries are gone or are on a verge of collapsing, like Cuba and Venesuella. When something is done for profit and benefit of someone, that something is almost always done better, faster and in other positive factors, compared to the things done for the sake of doing. Been there, seen that...

Quality of work in USSR was next to non existent and behind propaganda posters there were memes like "trim with file after assembly", "does not affect driving performance" and others. Almost all USSR industry was working at loss, i.e. every day of running those factories was costing money. It was logical to close most of them but they were subsidized from gas/oil export money. And when oil price fell in late 80s, USSR fall apart as country simply did not had money.

Or are you referring to forced/slave labor like in North Korea as an alternative? ;)

The Chinese automakers used it to build innovation systems capable of launching new models in 18 months vs the 5 to 7 years it takes the US OEMs. The US OEMs, bar Tesla, used it to finance BAU, and more fool them, and they’re paying the price now. Tesla used it to do some weird mix of innovation and making Musk grotesquely rich.

Not sure if making a new car model every 18 months is a good thing. ;) Even for phone models this seems to be too aggressive from the environment perspective. And EV's are supposed to be environment friendly and not make EV Waste

But I suppose you still have dishwasher, washing machine, dryer? Just load them in the morning and set schedule to afternoon and unload after returning home. Or are you an ascetic individual, which refrains from using machinery to make life easier and prefer to wash dishes/clothing by hand and then let them dry naturally? :)

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. ;)

Comment Re: V8's are great, but Trashdot, not so much. (Score 1) 384

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.
