How about from a performance not reliability (IE striping not redundancy) point of view, you could greatly improve transfer speed by striping across multiple platters !
What you are forgetting is that in a non hybrid car, a lot of the time the engine is either idling, or running at a speed which is nowhere near its most efficient, whereas a hybrid can have the engine running at its most efficient speed etc, and turn it off when not needed. now this is not going to give you as much of an efficiency boost as say a fuel cell powered car but it will give you a small but worthwhile boost and its available now. it also helps by getting car manufacturers to invest money in battery and electric motor tech, for later use in full electric cars.
if someone steals your identity, and DOESNT USE IT (ie doesnt affect you) then has he/she really stole your identity? because it is not at all proven that downloading music is detrimental (indeed , many people have suggested it is actually beneficial) to music sales. An identity theft analogy might be someone stealing your identity to DEPOSIT money into your account... I wouldn't complain, would you?>
no the article makes a mistake (claiming 120 watts per square inch heheh id love to see that, considering less than a watt of solar power falls on a square inch in direct sunlight) what it should have said (i assume) is 120watts per square meter, which makes sense since they claim 12% efficiency, and 12 % of the 1 KW that falls per square meter in strong sunlight is 120watts
this implies that the sheet 10 X14 feet produces around 1.5 killowatts, and costs around 500 bucks!!!!! GIMME GIMME I WANT ONE
I think you guys are misunderstanding: 3X more POWER not SPECIFIC POWER ie: 3 the power output in watts, not energy content in amp hours X volts, basicly, similar energy content, but you can get that enrgy into and out of the battery much more quickly, and it has a much longer life.
Doesnt sound like snake oil to me, as using nano structures vastly increases surface area available for chemical reactions to take place, which speeds reaction times, so id give it a 80% chance of not being a con. Also quite usefull as low comparitive power output (as compareed to energy or specific power)is one of the drawbacks of lithium, and hell, whos gonna complain at an extra few thousand charges?
one benefit not yet mentioned is the fact that no(well probably a tiny bit) unburnt methane is released into the environment, as would happen if this waste was allowed to decompose normally. This is VERY good in terms of the greenhouse effect as methane is MANY TIMES(6 maybe? cant remember) WORSE as a greenhouse gas than CO2, SO
- renewable (if used to decompose products which are renewable, eg sewage/offal) source of energy
- saves having to figure out what to do with that waste
- perhaps mini versions could be built, to allow us to have one in our back yard?
- MUCH better for the environment in terms of greenhouse gasses and water polution from waste
- where can i buy one NOW lol
Lets hope this doesnt get regulated into oblivion or similar by politicians who have sold their souls to the DEVIL....I mean current petroleum companies, although, with this many benifits, i dont think even they could stop it.
actually, more, mow much space do you have on your roof, bonnet and boot? maybe 6m^2?
so if that 4% for 1m^2 is correct (cant be bothered checking, plus it depends on car usage) then we are talking closer to 1/4 of your fuel costs
ok, your post makes more sense now, however, i live in australia, where we have plenty of houses and space, so here, it all comes down to how many solar cells can we afford, not how much space can we cover. I realise they need to be solar tracking for best efficiency, but, basically, the whole point of my post is that IF solar cells price per watt ever drops by a decent amount (something im expecting around 2010:) then space/powerrequirements will not be a problem.
Has anyone ever considered how much power could be generated by a solar powered road surface? obvious problems to overcome are cheap solar cells and tough clear coating, but if that ever happens, you could completely power one car per lane per 50 meters of road or so (during peak hour: a lot more as cars are mostly crawling along at low power). imagine a road surface with induction power transfer to the car (like that device designed to recharge gadgets that was on/. the other day), roads could pwer everything... lol ok now im just dreaming out loud but it'd be cool
please quote a reliable source for your figure of 50% are you trying to tell me that it takes 50% of the energy content of a litre of liquified hydrogen to actually liquify a litre of hydrogen? ( or for compressed hydrogen) this seems like nonsense to me, so unless you can back it up....
FIRST: you assume 10 percent efficiency, whereas average decent cells nowadays are more like 20 with good ones around 30
NEXT you assume only one square metre of solar cell space.... how big is your house? mine is around 8*20 metres = 160 m^2
SO if you take my house as an example, you are looking at 160m^2 * 200w (say)per m^2 * 8 decent sunlight hours per day = about 250 KWhours per day IF i cover my entire roof with panels, plenty to power multiple cars and the house and the neighbours house etc etc.
THE only problem with this scenario? due to a lack of widespread investment in solar technology, as opposed to oil or other fossil fuels, solar cells still cost about 5 bucks a watt, so your looking at an upfront investment of about 160 grand to cover my roof in panels. Now obviously i dont quite need that much power, but either way itll be a fair whack of money at current prices (otherwise i wouldve done it long ago). Hopefully some of the new thinner solar technologies coming out soon (within a year or two) will lower prices to a more reasonable level.
actually according to the reports ive read, the cell is supposed to debut in servers long before ps3 arrives, and i remember marketing estimates of 16 terraflops for a 1 rack server!!!!!!
I dont think anyone is realising the true potential of these chips, all they are seing is 4.6 ghz power chip and forgetting the multiple stream processors. Does anyone realise that the theoretical performance of this chip (one) is over 250 gigaflops!!!!? and there is supposedly 4 (or at least 2?) in a ps3 plus "GPU" (possibly with some traditional parts being taken over by the cell chip) SO one cell chip == 5* 6800 chips == about 40 or 50 high end pentium/athlon systems in theoretical performance, and even if only half of that can be utilised in real use, thats still 125 gigaflops!!!!! With four of these chips you have a top 500 supercomputer in a box!!!!
I think its sarcasm, you know, a dig at "Democracy, the belief in the collective wisdom of individual stupidity..."
not only that, only 50.000...1% of people have to believe something for it to be true via democratic majority rules (or less if there are more than 2 choices). Since 49.9999...%of people are below average inteligence, then if an idea is popular with stupid people, but is actually wrong, then it takes only 0.000000...1% of above average intelligent people to be mistaken and it will be voted/thought of as true.....
no one seems to be picking up on the implications of INKJET PRINTABLE ELECTRONICS::
Open Source Hardware!!!!!
download a design for a gadget off 'hardforge', print it out, and away you go. Dont like a design feature on the latest open ipod clone: change it yourself and print a personal custom model.
the point is that there is no need to solder anything, or attach any components, everything is printed, circuit, components, 'chips', everything. imagine being able to download the design to a new electronic gadget (eg mp3 player) off of bittorrent, and print it out in a few hours (minutes? days? i dunno). Just think open source HARDWARE!!
why not? couldn't thicker or thinner 'wires' or different conductivity ink alter the impedance of sections of the circuit?
forgive me if im wrong, IANAEL
when are these morons going to wake up and realise.. hey, its just a body, in its natural form, doing what its supposed to do, or what it enjoys doing. Oh hang on, their religion is built on crap like "sex is evil, sex is a sin" to keep everyone but the REAL wierdos sinning. Now Im not advocating child pornography, nor anything in which all involved parties have not consented to the action, but really, its 2004 for cripes sake, GET OVER IT ALREADY. if you werent all such prudes, you wouldnt mind explaing to your kids how sex works, without geting all embarrassed. I mean, it is HOW THEY WERE CREATED!!!!!. Note that this rant (and yes I realise it is a bit) is not aimed at all americans, or even the majority of americans(in fact the issue is world wide), just at those people who are too silly to realise a natural human act and desire when they see it. Unfortunately, these can screw it up for everyone else.

i should explain that the 500 buck figure comes from the 36c a square meter value quoted in the article

thank you, try the fish
forgot to add electrolysis efficiciency, which i believe is around 80 percent, but either way doesnt prevent the above solution

very good answer. hadnt thought about that but it makes perfect sense

take religion for instance...
by the same logic you could say its not the circular saw thats the tool, just the sawblade..... doesn't quite work im afraid
research
use in solar cell production
