Add a time limit to that as well and if you are not practiced at doing those type of problems you will never get the whole thing done in time. This is how it was done in most of the later engineering classes for me. Open book, open notes, open laptops, times 90 minute test, that took the professor about 45-60 to do. You were doomed if you didn't know what you were doing as you would only get 2/3rds the way though the test.
re-breed the waste and use it again. Funny thing about half lifes, the shorter they are the more deadly but the faster they decay...
There is no good reason (in a first world NATO/EU/etc country) to not re-breed the waste and make good use of it several times. Then once no longer hot enough for power generation, use it (in a double loop) to heat water, or provide heat to other industrial processes. It would make a nice stable heat source.
It was equipped to withstand a tsunami. Just a 6m(~18 feet) high one, not the 15m(45-50 foot) one that it got. Sure we could equip it to handle a 20m one, but what if an asteroid lands a bit off the coast, and generates a 200m high wave... what then?
You have a point about Chernobyl, that was 100% human negligence, but Fukushima wasn't much in the way of a human error. Sure in hindsight they could have built a wall that was 10% bigger than needed for the worst event on record prior to that, but that doesn't make much sense. Well as much as deciding to buy a land yacht because "Its bigger and heavier so I'll be safer in it" makes sense. There is some argument here that simply have more self contained, smaller reactors spread out would be a better idea. Anchor them to the bed rock, and so 3 of them have issues when this happened, that's fine as long as you don't eat the wreckage you should be just fine.
What happened to that study that showed that a adult human could eat the amount of waste that produced over 1 year needed to produce power for them and suffer no ill effects?
because last I knew, Google was simply using the syntax and then a special compiler to operate on that syntax to directly produce machine code. Using none of suns actual libraries. just ones with the same names.
I get where he is coming from, +$2 on a light bulb that will cost $70 over its life in electricity or +$50 that will cost $15 over its life? right the second is a better choice, assuming that it was also made in a world friendly sort of way, but do you have the cash right now to go out and buy 15+ of these $50 bulbs? if so could you pick me up a few?
I expect to pay a bit more to save down the road, but at some point I no longer have the up front capital to make it work, so I go back to buying what I can afford.
RIght but lots of people don't have the money now for saving that down the road. Say you could spend 70,000 right now to buy 1 car that would last the rest of your life and would get 60MPG. Better deal over your life than 20,000 and 40MPG right? well sure but you need 70,000 right now.
Hmm. I know i can buy 92% eff. 460V 3 phase motors. I'd assume that I could get a similar number for a generator. Using a 3 phase generator makes the ac-DC conversion very efficient. Now I'm not sure about the games that need to be played to do DC->AC, but the mechanical industry does that all the time, see VFDs. Of course most of these systems don't need to move, and are rather large, and needs a surprising amount of cooling, but that just seems to be a packaging issue.
The math does seem to point towards the parallel hybrid as the most efficient system, but you missed counting in the costs(and weight) of the drive trains. The parallel hybrid needs both a transmission(crappy slushbox on most US cars) on the ICE engine, and a some way to merge the powers together. All of those cause a further loss of efficiency. You need to look at the system from power input(i.e. energy in the fuel), all the way to the last step in the drive train. Both systems have ways to recover some/all of the energy, so we will assume that it is the same for both systems. Some other fun things that are "easy" to do with an all electric power train, individual motors for each wheel, allowing some fun things regarding all wheel drive and stability control.
All of that is ignoring things like maintenance costs/hassle, and the noise the systems make. I'm not sure how loud this new thing is, but at least with an electric drive system there is the possibility that the ICE is off. Also with enough batteries on board and some local "green" power generation, I may not use all that much fuel at all. If the ICE is the prime mover, then I'll likely not be able to drive an electric car most of the time.
I'd agree, my commute is 16 miles right now. I'd love to bike it, but even if i can average 30MPH the whole way, that is 30 minutes on a bike. I'd be more likely to average 15MPH or less, making the bike ride an hour. Would be good exercise, but the drive is 20-30 minutes just about every day(as long as there is no snow).
This is why Windows remains on 90% of most computers, despite several Linux distro's being "average person ready" for 2 years now and a concerted fanboy marketing campaign by Apple, Microsoft's dominance on the desktop remains unchallenged. Why, well because Windows does, it does 99% of what 99% of people need it to. It does nothing well, it's a bloated, buggy pile of crap but it allows people to get things done.
Well for me windows is still on computers i use, because of excel sheets with macros, vendor selection software that only runs on windows(not even OSX), and the fact that autocad, inventor, and solidworks are still only available there. My home desktop runs Gentoo though, as does the home server, sadly that keeps the mostly idle server out of HTPC duty as there still isn't netflix for linux.
So are, but my Mother doesn't want to tinker with her phone at all, no sticking apps on the desktops, no setting up the colors, swipe gestures, button actions. She won't be rooting it, and installing CM7. All that after spending 20 years debugging mainframe OS code. SO yes, there are lots of people that expect a toaster like experience. "insert bread, press button, receive toast".
1) Keyboard, no use for usb3 there. 2) mouse, Same as keyboard. 3) Cell phone, okay sure sending some music to it would be nice if it was a bit faster, although i think i'd need to replace the class 4 sd card in it. 4) Printer, same as keyboard 5) kindle, Same as phone. 6) jumpdrive from 3 years ago, mostly the same as the phone but i'd need to replace the whole jumpdrive 7) portable harddrive(if i had one) is still likely better off on esata, of course that means 2 cords instead of maybe one(can you power a 3.5" HDD with usb3?)
Hmm not finding anything I'd want to use USB3 for. Now, give me powered HDMI 1.4/lightpeak/etc and we can start talking. A single cord to my monitor, sign me up.
some of us fence sitters can't be bothered to wait for AM3b in mini-itx to come out, when the first real* AM3 board only recently came out. so am3B launches in a month or so in uatx and atx, September/October the mini-itx boards without pci-e launch, and just about when i'm in the market for a new box(i.e. 3-5 years from now), I'll be able to get a AM3+ mini-itx. At least AM3+ uses ddr3, and pci-e2.0.
*real in this case means that it has a pci-e slot in it.
If you have a case, monitor and keyboard/mouse, You can do a Athlon X3 or X4 + uatx motherboard + 4GB ram + 1TB HDD + new PSU for right around 300-400.
Now go PhenomII x6, 8GB ram, two 2TB drives, and a GTS450, all in a mini-itx case around the size of two 1L soda bottles, and sure the costs are closer to 700-800. Ma and Pa facebook don't really need that. The integrated video will work just fine, as will 4GB of ram. Even two peoples music collections ill fit on 1TB of HDD. Ma and Pa facebook are not really ripping videos. For storing pictures of johnny facebook, use facebook, flicker, etc or buy a cheep external HDD or keep using the usb2.0 one they have.
Which is nothing like chucking it around a track. I would not expect to get 211 track or "play" miles out of it, and i would expect to treat it nice and get a few more than 211 out of it.
hmm? i hooked my android phone up to my work e-mail without any more work than it took to set up outlook. I seem to have most/all of the same features outlook has as well. Granted I use very few of the advanced exchange features, heck he hardly use the calendar for meetings at work.
Also hasn't google been saying that Honeycomb will be a tablet only(officially) version? If I am remembering that correctly, i'm not sure how the 3.0 stuff has much to do with with this discussion.
We already have a community distribution of android, CyanogenMOD. As for fragmentation it's more that there hasn't really been much in the way of a "screen shall be X by Y resolution, and the CPU shall be xxx speed ARM or equivalent." Thats about all they are doing now, is setting the hardware minimum higher than they have in the past. I haven't seen anything to the effect of "Handset will be made on nothing less than 24k gold, and the belly button lint of Steve jobs"
My bet is sadly on the closed one winning. Most people view phones* as appliances and as such they should just work.
*I keep thinking of mine as a mini-laptop, but that still makes me a bit grumpy as i'd like to be able to script it, and tinker with it even more than CyanogenMOD will let me.

you mean "=average(A1:A5)" isn't how you do that?
Too bad that lots of stuff highschoolers have to do (SAT||ACT) don't allow much over a drug store calc with trig functions. So no TI-86 anyways.

60% electric motors? what are you buying? DC stepper motors? 3 phase AC motors can be had in the >90% range.

are there any without Atom or VIA or one of those lowend AMD things?
Lets see usb devices in my life...
1) Keyboard, no use for usb3 there.
