Comment Re:Making 26 YOs work 80 hour weeks is easier too. (Score 1) 180

I agree they're not much good on a smooth floor, but I use a broom for that. They work very well in that environment. We've had a Dyson for a long time and aside from eating its skinny little belts trivially if you clog it with hair, it's a very good machine for us. And it pulls stuff out of the carpet that other vacs don't, which is its mission...

When arguing ICE vs EV, I get the impression that noise and vibration is considered a good thing with ICE.

Some people seem to think so, and in a sports car that's as may be, but in other kinds of cars it's not so much. The thing is, that's not really a big problem. There's only a small amount of pleasant noise from my Audi (all real, none generated) and there's really no discernible vibration because of the fancy-pants engine mount setup, which is not even active. It's just good. The real benefits of EVs are not so much in sound (although there are some there) as in efficiency. When the batteries become cheaper, and when typical range gets a bit better, they will become ubiquitous for this reason.

One day you should actually drive an EV instead of just spurting unjustified nonsense.

You can get a lovely used luxury car with better interior quality than a Tesla for around ten grand in very good condition. (The best examples of older luxobarges seem to run about that.) Per dollar, it walks all over the Tesla. Yes, the Tesla is a better car. It's not a hundred thousand dollars better. Used Teslas won't be that cheap for decades.

I've watched the Jay Leno's Garage on his Doble. It was an amazing thing. But the system takes up too much space. Compare the Doble to a Fiesta with a 1 liter Ecoboost engine and there's no contest in any category. Physics limits how small a steam system can be; it could perhaps be more compact than in the Doble, but how much more? If you're going to go that far in your quest for a new-old engine, NASA's proven Stirling engine tech is probably a better example.

Whatever you do, don't take a Tesla test drive. It will make you hate your slow, noisy, polluting ICE car forever.

What makes me hate my ICE car is unreliability. But when it's working, my A8 Quattro is not exactly an unpleasant driving experience. You can get a spectacular (old) one for ten grand and the price difference will pay for fuel just about for life. I should have spent more on mine :p

Comment Can we just get rid of it? (Score 1) 61

The only bias I see is that for some reason, Facebook seems to think I'm in any way interested in celebrity gossip, because that's about all that ever shows up in the "Trending" section for me.

I'm interested in science and technology, but every "trending" topic I seem to see is something about what Britney Spears ate for breakfast, or whose dress Catelyn Jenner wore to the mall, or some other equally banal and useless piece of "news" about some celebrity that I don't give a crap about.

I'm not even exaggerating. My current "trending" topics include:

  • - What's coming up on Netflix next month (US Netflix, that is. I'm Canadian and watch Canadian Netflix, and we don't get the same new movies the US does, so it's even more useless)
  • - "Go topless day"
  • - Some sort of conspiracy theory about Herman Cain and Epi Pens
  • - Some nonsense about whether or not some pastor endorsed Donald Trump or not
  • - Something about some guy I've never heard of who got roasted by Twitter due to his hairstyle
  • - Five reasons to see some movie I've never heard of
  • - The 77th anniversary of The Wizard of Oz
  • - Something about Britney Spears doing karaoke

As you can see, my "trending" doesn't have a Liberal or Conservative slant -- it just has a inanely stupid slant.

"Trending" is the least useful part of Facebook, and personally I wish they'd just get rid of it altogether.

There are many other (large) industries that rely heavily on batteries. They've been heavily researched for over 100 years.

Yes, but so have ICEs, and they still suck. Only minor improvements in efficiency have been realized in the last forty years. A forty year old turbo diesel still provides pretty good thermodynamic efficiency. It does it without producing much CO2 as a result, although it will tend to crank out quite a bit of NOx. Over that time, automotive ICE efficiency has improved by only in the low double digit percents, while electric motor efficiency has about doubled — and it's over three times as good as an ICE.

Cars are fun, I like engine noises as much as or even more than the next guy, but ICEs blow.

There is already an awesome battery tech, holding about 10kWh of energy in a small package that already exist, it's good old gas. The only problem is that it takes 100 millions years to produce.

The other problem is that you can't just feed it into an electric motor. You have to either feed it into a fuel cell which is lame for many reasons which I should not need to enumerate here, or you have to feed it into an ICE which is lame for even more reasons which etc etc. Or an external combustion engine, but (stationary generation aside) that only really works for trains and it's not really convenient there, either. Electric motors are wonderful in every way compared to ICEs, and batteries are wonderful in most ways compared to fuel cells despite their many annoying failings. In fact, you can't efficiently build a fuel cell car without including battery in the motive power system.

EVs would have been overtaken by ICE technology regardless of whatever conspiratal notions you are imagining.

ICEs still provide a superior driving experience per dollar, and most people who have an EV wouldn't have one if not for subsidies... to compete with the entrenched energy monopolies' subsidies.

Comment Good on him (Score 2, Interesting) 180

Better battery tech is about the most important thing in energy today, because it will let us make more use of "alternative" energy sources (you know, ones which were in use to do work long before anyone was using electricity, or building ICEs or steam turbines or even steam engines) right now. The only thing that might be even more compelling in the short term would be a safe way to store apparently physics-defying quantities of hydrogen and release small or large amounts of it later as necessary without having to expend a lot of energy to do so, but even that has less applications than a better battery.

One (okay, I) wonder[s] where battery tech would be today if EVs had remained dominant and not been pushed out by subsidized oil and coal.

Comment Insufficiently Realistic (Score 4, Insightful) 296

Until the dolls literally spray genuine, authentic baby shit and vomit on you in the middle of the night, they are going to be inadequate to the task of dissuading girls from wanting to make babies.

If you can't actually fill them with a truly realistic substitute for unwanted infant fluids, they're worthless.

Nobody else needs a DSLR, so this is a complete non-problem.

How does this excuse having a terrible interface?

You only think it's terrible because you don't need what it does. If you did, then you would think it's a great interface, because it does what you need. This is how I can tell you don't need a DSLR. You need a simplified, Fisher-Price camera. Sometimes those are great, and I have one. When I am just taking snapshots, that's what I use, because it is simple and good and small and light. I don't use the DSLR at all unless I need something it's got that the super zoom doesn't, like RAW. It doesn't have any more lens.

Because I need to be able to change the setting quickly, and also while holding the camera with both hands.

So make the settings that need to be changed fast easy to change fast.

Yes, that's what they have done. You're just seeing settings you don't need to change and thinking about how inconvenient all those settings are for you, because you think the universe revolves around your balls.

There are a lot of features you could not possibly change faster than the time it takes to pull out a cell phone that given that they are buried in a menu somewhere.

You are completely incorrect. No camera has more than three or four levels of menus and I can navigate a menu structure like that much faster than I can get my phone out of my pocket. I may not have a spare hand at all, so the phone might not be an option at all. I can work my phone menus with one hand. I cannot work the phone and the camera at the same time with one hand.

Your solutions are dumb because they make the situation more complicated. All cameras will eventually have fancy-pants multitouch displays and then there will be absolutely no benefit whatsoever to phone interfaces. In the interim, that kind of functionality is of use only to a subset of users. If a brand did what you describe then the professionals would go elsewhere and the company would rapidly gain a reputation for making toys and then go away.
