next range: well even a crappy home made conversion of a normal car to lead acid powered electric gets roughly 100kms range, using second hand old motors , existing drive train etc.
now assuming we use the mentioned lithiums instead of lead acid (or the nimh they tend to use today) we get ~4 times the range, then factor in a new more efficient motor, and car designed from the ground up for electric use, and 600 - 1200 kms range on a charge seems entirely feasable, with the nice 2 mins recharge. (let alone using lithium sulphur batteries if/when they are available, double to triple the capacity again, or fuel cells...)
add some nice decent efficiency solar cells giving maybe 1 or 2 Kw (assuming ~3-5m^2 area at ~25-35% efficiency) on a nice sunny day, boosting the day range up a lot (especially for short trips, where recharging might not be necessary at all)
the main reasons we dont have any decent production electric cars now is because car companies dont want a car to turn into a chasis, some electric motors and batteries and electronics (too easy for cheap chinese knockoffs) after investing so much in petrol engines, so wont do the reasearch necessary to make it a reality, oil companies dont want to lose their market, and almost everyone else believes the lie that electric cars are unfeasable.
next to the comment that we always need oil, i have no doubt at all that if there was no geological oil available, we would have as many of these operating thermal conversion of almost any organic garbage to oil as is necessary to supply us with the required oil(actually these are supposed to be efficient enough to supply the entire US oil needs just using US agricultural waste, solving two problems at once, let alone other waste. no need to dig any more out of the ground at all)
so as you can see, oil production for plastics etc is not theoretical problem only a political one i guess, even without geological oil, and electric cars CAN work fine:)
dont know where you got this strange (and WRONG) idea from, the average amount of solar energy per m^2 on a nice sunny day is over a kilowatt, meaning your average decent size house block could provide about 1 Megawatt of power, if we could actually get it all (which we cant, although it looks as if soon we may be able to get about half of it).
The only real issue with providing all our needed power with solar energy is the current cost for the solar cells. if (when?) cheap solar cells come to market (such as the thin flexible plastic ones we hear about on/. from time to time, or sliver cells using much less silicon), even low efficiency ones, there will be no more energy problem (unless of course we all drastically raise our energy use, and i do mean drastically, or oil companies buy laws to prevent their use )
I agree whole heartedly with most of what you said, but im a bit curious about the "milk doesnt need refrigeration" bit.... if I leave milk out of the fridge it goes off pretty damn quick ( hours versus nearly a week in the fridge), where did you get the idea that it doesnt need refrigeration (or are you talking about long life milk, or using it all up within a few hours of getting it?)
lets see.. average house maybe 10 * 15 metres or more = 150 m^2 surface area on the roof. the sun gives a daily average of about 200 watts per m^2 (peaks at over 1KW at noon (in sunny places), drops to 0 at night)
that gives us 150*200 = 30 KW of average power. add in a 20% efficient cell and you've got 6 KW average power, for every house, (obviously we need a way to store it during the day for night use), being way more than enough for most houses
then youve got roads (ok pipe dream, requires the invention of a transparent coating tough enough to be driven on, not impossible but....), footpaths (similar), wastelands and other non important land, and anywhere else we could stickem. And this is all with 20% efficient cells. Add a 50% efficient cell in there, you get 15KW average power for every house.
so what does all this mean? basically, the only problem (but a big one) with using solar power is the current cost (mainly due to the cost of the sillicon used). With new sliver technology (ultra thin solar cells, using vastly less sillicon), polymer solar cells and other future developments, this is not a problem
although your point is one I had not thought of, I have to say I dont agree (in most cases) I can think of some scenes in movies that work well at slow rates (ie get an artistic feel bedause of it) but you can always emulate these if you want by showing 60fps with two frames per image (half the rate)
What your saying however is kind of like saying "sculpting a statue in nice smooth marble is not artistic, the only way to sculpt artisticly is to leave some rough edges", sure, some artists will use the roughness of the piece to convey something , but others will want to convey whatever it is they are saying using a smooth piece of marble. Limiting all artists to the rough piece limits the art that can be made. (not to mention that I dont buy the whole faster frame-rates/less interesting thing, that s just rubbish)
hehe should of really read the extra info someone posted, 60 Hz progressive !!!!! YAY (although I'd prolly go even further hehe), although this makes me wonder where I went wrong in my earlier calculations: 24 Gb/s/( 60 FPS * 33 000 000 pixels) = 12 bits of info per pixel ?????? 3 bit rgb channels??? heheh yay for CGA or whatever this is hehe
I guess they must have lowered the FPS in this one to 25fps for testing
What is annoying to me is that even with all those pixels, which is coming close to enough to properly completely trick the eye (some people estimate that the eye can see somewhere round 5000 by 10000 "pixels" accross our full field of view, maybe more for some people), they have left it as ~25 frames a second (~32,000,000 pixels * 3 bytes of info per pixel (but why only use 24bit true colour when your going for this quality?) is roughly 96 MB per frame, and the uncompressed total was ~2.5 GB per second, which is roughly 25 frames a second.
I realise that they most likely did this becouse it would be damn hard to get any higher with that amount of data per frame, but still, if your someone who is designing a spec and aiming for a new super dooper standard, PLEASE UP THE FRAME RATE. 25 FPS SUCKS for fast action.
also, anyone who is going to argue with this and say 25 is all you need, please read and understand this before hand, or else shut up:

and to all the responses to yourcomment by people with a "24bit colour is good enough" and "cd quality is good enough", what the hell are you doing on slashdot if your not interested in improving technology to the point where its perfect, not just "good enough" (and no, its NOT good enough, many people with keen ears and good eyes, myself included, can notice the difference as you go to a higher quality sound/colour )(ok the colour I have not seen higher but i have seen the banding at 24bit, meaning higher is needed, plus of course theres the whole monitor colour gamut problem, if you dont know what that is, look it up before responding please)
I love the clarity in music in 24bit 96khz on my audigy 4 with quality speakers (when I can find it, not often yet), as compared to CD source music, but then Ive been listening to my dads quality hifi gear all my life, and I am a musician, so my ears may be a lot more sensitive than the average persons.
please stop assuming just because your senses are not able to detect the difference, that someone elses cannot
in my case, I have a hard time watching/reading any political news, due to it PISSING ME OFF with all the BULLSHIT that occurs all the time, with nothing much I can do about it. Even though I still read/watch it every now and the, my point is that im not so much apathetic as frustrated with many world events, it stresses me out too much worrying about it, so i tend to avoid it. Even so, since im basically a net addict, I still know a lot more of whats going on than most other people I know (and definately more than anyone I know in the tech trend area).
I thought the estimate was much higher than this? arent they supposed to have possibly the most combined computing power of any company (excluding nsa and similar government groups), somewhere in the order of 100 000 pc's, which, at an estimate of average speed of 1.5 ghz come in somewhere round 2 or 3 gigaflops each, for a total of somewhere round 200 to 300 teraflops (admittedly this power is not tightly coupled like a supercomputer,as it does not need to be for their purposes, but you did use google as an example, so...).
this score was NOT gained by runnning at 1ghz, it was only stable at 1ghz in 2d, they backed off to 8 hundred and something for the 3dmark. see xtremesystems.com/forums for more info (in extreme 3d section)
have a look at xtremesystems.com/forums, this is where they talked about it first (I was reading it there a couple of days ago). at that stage they had graphics core at 1.0 something ghz and memory at 2.0 something ghz, but it was only stable in 2d mode. the highest they could get in 3dmark at that stage was around 12400 and yes, that was with the overclock backed off a bit to 800 and something
in other words... still impressive (no other chip has been able to overclock to 1ghz, even in 2d mode) but not quite what you were hoping for
I've come to the conclusion that what it all comes down to is :
parents are too stupid and embarrased to talk about sex with their kids (even though its a natural, REQUISITE, enjoyable, and relatively safe part of life when done right) so protest it being shown anywhere where a child might see it and ask embarrasing questions, whereas any kid with a sibling or two understands violence and any questions are seemingly less embarrassing to answer (although I think we should all be MUCH MORE embarrassed explaining why we are killing other human beings who have not attacked us than explaining a natural beautiful part of life)
(I also think it's mostly not concious that this is (part of) the reason, and its also drillied into many from a young age that sex is bad/naughty/dirty/sinfull/embarrasing so people accept it without thinking bout it)
Here in Melbourne, Australia almost all the Universities now have a games programming course of some description. I will actually be lecturing a 3rd year games programming subject at latrobe uni here next year and have been head tutor for a few games subjects for a while now (we have had a specific games programming stream of CS for a few years now).
actually the loud buttton is normally a dynamic range compressor. It takes the quieter(sp?) sounds and brings them up to a volume level closer to the louder sounds,
with the end result being an apparent increase in volume with no increase in the maximum actual volume outputted (ie: voltage to the speakers).
perhaps I should have said struggling musician/computing student for 10 years hehe. Mostly due to being busy doing an honours/starting a phd degree in comp sci games programming. I dont have a contract at the moment, and would probably prefer not to (at least not with any RIAA affiliated recording company, meaning almost all of them. I make quite decent money (compared to normal jobs, not rock stars) from my music, however I have not yet done anything noteworthy with it (i'm recording at the moment, but I am also trying to write my thesis.....).
I plan on releasing my music free with no DRM throughout my career (with cheap CD's in stores as well I hope), and have donations/ etc on the website you download it from, the main idea being I dont feel I should tell people what my music is worth to them, I should let them decide. As well as regular paid gigs in pubs and cafes, I also go out busking, which is quite profitable, and also quite enjoyable: I deliberately dress nicely to remove pity money from the equation, so I know that Im getting exactly what the audience thinks Im worth. This is the business model I would prefer my music to be based on
HAHAHAHAHAHAHAAAAAAAAAAAAAA Bonk (me laughing my head off)
I'm sorry, whats your email address? head in sand @ living under ayers rock
Quoting capitalist reasons (dont take this the wrong way, I believe true capitalism *could* be a good system, if it was ever actually brought in...)
for why the RIAA's contracts are fair doesn't work. They are a bunch of convicted price fixers who hold (perhaps that should/will be held? here's hoping)
an almost complete monopoly on the promoting, publishing and sale of of music.
When you said "Barring government protection, all companies ultimately serve the consumer" you forgot, the RIAA HAS government protection!! It seems almost every day I hear about yet another moronic law with no purpose except to screw the artists AND consumers out of more money, being promoted by politicians who are so obviously really just RIAA employees (or whatever other rich conglomerate decides to buy them off).
It's easy enough to say "just don't sign the contract" or to say that other people would gladly take their job (ie sign the contract in their place) but what you are really saying is "just struggle with your dream for another decade or two till you are to old and tired to get anywhere". In most industries, you have decent alternatives: if your a talented employee, and you dont like the terms in a contract, you at least have some chance of finding another employer with better conditions. In the music industry, the RIAA/ **AA is the Only one . The RIAA neither serves the consumer or the artist, only themselves.
As an artist (I have been playing music for over 10 years) , If I had a decent fair chance of getting radio play/other exposure by going it alone, and therefore a decent alternative to signing up, I would agree, and say let the RIAA put whatever they want in their contracts. But the fact is, with almost every radiostation owned by the same bullshit company, rampant Payola, and the price fixing, pressure to sell the approved products etc that happens in music stores, there is no decent alternative.
Of course I guess if I was a soulless bastard who had a government sponsored Monopoly on a multibillion dollar industry, I wouldnt want to let it go either.
