  1. ultracaps aren't happening on Cadillac Unveils Pricier Alternative To Tesla Model S · · Score: 1

    You made sense until your last word. Ultra-capacitors aren't happening. As batteries steadily get cheaper, you can use a bigger battery. A bigger battery can handle more power, so it can cope with more braking regen and recharge faster (and deliver more horsepower); and it's not cycled as much as a smaller battery, so it lasts longer. That reduces the fast-charge and longevity benefits of ultracaps, which are still far more expensive and heavier than a lithium-ion battery of the energy. Ionova claims 10 Wh/kg for their ultracaps while li-on is over 100 Wh/kg. In theory you can recharge an ultracap in seconds, but the future fast charger to recharge a Model S battery in a minute has to deliver 7000 amps at 500V instead of ~240 amps, so it's going to cost a fortune.

    Ultracaps still have a chance in hybrids, the Prius only has a 1.3 kWh battery. Only price keeps ultracaps from replacing that battery. But again, as batteries get cheaper, more people will expect to be able to plug in.

  2. movies as raw material, as William Gibson foretold on LucasFilm Combines Video Games and Movies To Eliminate Post-Production · · Score: 1

    Others have commented how this will lead to dumbed-down movies with videogame features and Mario/Angry Birds franchise tie-ins, such as

    Dead or Alive Xtreme Volleyball models, in swimsuits, in all the future movies!

    ... all with the face and voice of Jar Jar Binks ...

    But this would actually be fantastic if if the movie watcher got to control the remix. There are cut-scenes in Red Dead Redemption that are rival anything in a movie (Marston's last encounter with Bonnie, so polite, so suffused with longing!) and then you can enter the world as one of the characters. Why limit your favorite characters to one setting, legal threats from George Lucas notwithstanding?

    In a marvelous talk 10 years ago to the Director's Guild of America (read it!), William Gibson explores the long past of movie-making as storytelling, and predicts the future of it.

    Any linear narrative film, for instance, can serve as the armature for what we would think of as a virtual reality, but which Johnny X, eight-year-old end-point consumer, up the line, thinks of as how he looks at stuff. If he discovers, say, Steve McQueen in The Great Escape, he might idly pause to allow his avatar a freestyle Hong Kong kick-fest with the German guards in the prison camp. Just because he can. Because he’s always been able to. He doesn’t think about these things. He probably doesn’t fully understand that that hasn’t always been possible. He doesn’t know that you weren’t always able to explore the sets virtually, see them from any angle, or that you couldn’t open doors and enter rooms that never actually appeared in the original film.

    Or maybe, if his attention span wavers, he’ll opt to experience the film as if shot from the POV of that baseball that McQueen keeps tossing.

    Somewhere in the countless preferences in Johnny’s system there’s one that puts high-rez, highly expressive dog-heads on all of the characters. He doesn’t know that this setting is based on a once-popular Edwardian folk-motif of poker-playing dogs, but that’s okay; he’s not a history professor, and if he needed to know, the system would tell him. You get complete breed-selection, too, with the dog-head setting, but that was all something he enjoyed more when he was still a little kid.

    But later in the afternoon he’s run across something called The Hours, and he’s not much into it at all, but then he wonders how these women would look if he put the dog-heads on them. And actually it’s pretty good, then, with the dog-heads on, so then he opts for the freestyle Hong Kong kick-fest ...

    Because I see Johnny falling asleep now in his darkened bedroom, and atop the heirloom Ikea bureau, the one that belonged to his grandmother, which his mother has recently had restored, there is a freshly-extruded resin action-figure, another instantaneous product of Johnny’s entertainment system.

    It is a woman, posed balletically, as if in flight on John Wu wires.

    It is Meryl Streep, as she appears in The Hours.

    She has the head of a chihuahua.

  3. the Pre-viz becomes the movie on LucasFilm Combines Video Games and Movies To Eliminate Post-Production · · Score: 1

    What you said, definitely. DVD extras (the best part of Star Wars Episode III: Revenge of the Sith) show preproduction steadily evolving. Nearly all movies are story-boarded before production, and animation houses have always made animatics showing the key frames and shifts of the camera. Nowadays effects-heavy movie scenes are pre-visualized on a computer: someone builds a 3-D world for the scene, puts some 3-D character models in it, animates the models, and then moves a virtual camera around to create a computer animation of the sequence of shots. The result is a clunky computer videogame cut-scene version of the sequence.

    Which raises the interesting prospect that as computer graphics continue to improve, film makers will stop at the pre-visualization and declare victory. Why make a movie at all when it already exists? Five years ago after watching the "making of" featurette for the effects-heavy movie Hancock I wrote

    You see Charlize Theron watching the pre-viz on a Mac notebook, watching her 3-D character to learn what she's supposed to do in the shot! ... The cameramen, the actors, even the director, all watch a movie that already exists that dictates what they need to do.

    So record the actors at the table reading of the script, lip-sync the existing character models with their voices, and you have the movie. Perhaps if the real-world actors can do a better job emoting than the pre-viz animators (a big "if" for some actors!), film them and composite into the existing movie.

    Leasing an EV is a good idea, if you have a regular 40 mile commute get a Volt or Leaf right now and you may save money. But Better Place didn't lease you "your" battery, because it regularly gets swapped for something else. They sold you electric miles (Shai Agassi made it sound like he was freeing you from that expensive battery pack, you'd just pay to drive around cheaply on electricity). But that means buying a car becomes a messy three-way between you, the car manufacturer, and the "provider of a charged battery". And since most people can (and want to) recharge at home for most of their driving, BP had to stop you from plugging into a wall outlet for cheap kWh in order to make their finances work. Others here allege they used a unique connector, my understanding is they would meter your home EV charging station separately, and you could only recharge at Better Place's public stations. It was a complete mess. The genuine benefit of a quick swap during a long trip costs big money to deliver, and BP's model could only do it by making all your regular recharge and driving much more expensive, eliminating the "cheap running costs" benefit of EVs.

BP hoped that customers would demand swap capability so other car companies would adopt it, but it didn't happen, and car manufactures have instead adopted many different chemistries, layouts, placement within the car, air vs. water cooling...

    EV batteries are built up from multiple slabs or sheets. Already if your battery breaks, you only replace the defective module. You could imagine swapping the individual modules for charged ones, but each still weighs around 40 pounds and has be reattached to high-voltage high-current wiring and the cooling system. It's an order of magnitude harder than prying out 8 D cells from your boombox, and again there's no "D cell" standard for EVs.

    Maybe there could be a standard for a battery extender, a cage in the trunk where you can add several of these modules to your city EV for a long trip.
