It is worse, because portable ICEs are far less efficient than a non-portable centralized large power station at extracting that energy. And that's ignoring the potential for even more efficient nuclear and fusion power stations of the future. Even solar power stations can be used of course.
If it's really overnight like you say, and the fumes are cleaner (not just in carbon emissions but also smell/pollution wise), then that would be quite cool I guess. It's just it's hard to be excited about a stop gap solution which would still force sky high gas prices and maintenance costs on drivers.
Is this going to be just used for replacing gas in our over-engineered ICE cars? If so, then this is potentially very unexciting. Battery tech is surely the future, especially as we're seeing at least 5% gains in energy density year after year.
Granted, if it's as an economical alternative for creating energy other than coal or nuclear for general use, then sure, full steam ahead!
That's really good to hear. Tell you friend he's doing a great job and to keep up the good work.
Elon is quite a character and I believe he really wants to make the world a better place (rather than just in it for the cash). I hope he continues and if anything goes even further to ensure maintenance is kept to a minimum for the benefit of everyone as a whole.
Even if you have another ten there, it's very easy to envisage getting unlucky with the first say, 3, and then automatically taking a dislike to any you meet after that from the outset.
You'd need to know at least 10 people who enjoyed ping-pong (and preferably 20 or even 30) for what you said to have at least a modicum of plausibility.
Could there be an infinite number of souls? If so, why am I so 'early on', and 'only' the 10 billionth soul to exist instead of the 10^99999999999 (and much higher) soul to exist?
It's this conundrum which makes me think there's only one soul and it lives everybody's lives one by one somehow.
Yes, they do need to challenge Tesla, as GM's current electric cars are inferior in almost every way (other than price). If they don't, then when Tesla comes out with their sub $30000 model, it could be goodnight for GM (and other dinosaurs who refuse to accept EV is the future).
If you took 5 minutes to look at reviews on Amazon, you'd see the latest Intel, Samsung and Crucial drives are much higher rated. 5 minutes of research can spare you up to 100x in pain and time when something goes wrong.
Thanks. Yeah the unheard overtones of 22khz square wave makes sense.
However, a while back, I created the equivalent of a square wave (well, say 1000 partials worth), but randomly off-setted the phases of all the frequencies. So in principle, it should sound the same, but didn't. There was a similar but discernible difference between these two theoretically 'identical' waves.
That leads me to believe it's not just the frequency content of the wave that makes a difference to what we hear, but also the basic shape.
Of course, maybe that was poor speakers/sound hardware though...
I'm not saying that at all. I'm saying I've never heard reasoning based on what I've said, or an answer to such things.
I expect to be wrong (as I said in my previous post), but it's mildly irritating how the issue is tucked away, and your post makes things a bit more bitter.
Thanks that's a good point, though I do wonder if in practice, the result will be as you describe (especially since hardware is so imperfect).
And I'd still like to hear the answer to the frequencies between 14700 and 22050. A 14700 wave will have a pattern which repeats every 3 samples. A 22050 wave will repeat every two samples. If you go between these frequencies, you'll get aliasing problems, just as my checkerboard picture full of single black/white pixels demonstrates if you try to stretch it.
Yes, a 44kHz can cover the ear's range, if your preferred timbre is a square wave, that is.
Think about it; you can't achieve a 22500 Hz wave unless the sample is fully up, then fully down, then fully up etc. etc. Such sounds will automatically be louder than a hypothetical sine wave at that frequency, unless you reduce the amplitude, but of course, it's still just a square wave. Also, if you reduce the frequency just slightly, you get aliasing effects creeping in to make matters worse (like trying to resize a checkerboard of black/white pixels, each only a single pixel in size).
Okay, everything I just wrote may be based on ignorance, but I'd like to know why, as *noone* ever brings up the issue I just raised, despite its apparent obviousness. Strangely enough...
it represents traders thinking about what other traders will value.
As an investor myself (go Tesla!), I see where you're coming from, but to me that's a layer of indirection from the inner workings of my mind, the closest to which I would say something more like: "How much of a market slice will they get in the future compared to other car companies, and value it according to their current market caps".
So the fact that the stock price is undervalued (or overvalued) by the public is a side effect of that, rather than the main thing to look at.
If we must have clear skies for stargazing, but want well-lit cities, why not have all lighting off for just a few days each year. Everyone can then gaze in awe at the sky, and have practicality the rest of the time.
It could become a cultural thing where everyone participates. Even a little light pollution wrecks the experience of a REALLY clear deep black sky, so I say it's all or nothing.
Why? Is it the the slowness of it all (reminds me of download.com), or the stark use of a white backdrop against a black backdrop maybe? (which yeah doesn't look great).
At least it doesn't have that stupid new fad of very light grey text on a white backdrop.
Yes, the third idea is obviously best, since manufacturers which aim above a 5* rating won't be needlessly capped.
It also allows comparison between old cars and new cars. For example, if someone wants to upgrade their old year 2000 car, they can compare the safety in a much more consistent manner.
Basically, it's much more elegant, and I'm a little in awe why they haven't already made it like that.

Where's the post score filter? I love being able to hide or semi-hide all posts below a certain threshold.
Who are they in debt to? I never get to know that bit of info. And aren't those same countries also in debt, and so it all balances out somewhat?

Over engineered in what way? Complexity, or tolerance limits (e.g: using a stronger metal (overly strong) to ensure reliability) ?
Even if you have another ten there, it's very easy to envisage getting unlucky with the first say, 3, and then automatically taking a dislike to any you meet after that from the outset.

At least it makes investing an easier decision ;)

How can Apple be only 26% profit margin when they price their stuff at least double that of other manufacturers?

Well it's the market's best guess of it. I doubt anywhere else will you get a more accurate figure.
Thanks for the mention of that Android app - I'll give it a go! Cool that it has lucid dreaming support too...
What kind of brain injury? How do people act afterwards?
