Reference the B1 Lancer Bomber. It is not stealth, like the B2, but it is designed for supersonic flight. Published specs say it travels at 1.25 Mach, so it is no match for a SR-71 or the SR-72, however it is capable of carrying 134,000 lbs of armaments.
Given the maximum sweep of the wings on the Lancer (67 degrees), a napkin calculation of asin(1/(90-67)) indicates the maximum speed is roughly Mach 2.49.
This is only a rough computation, and does not take into account engine requirements, etc., but it does suggest that the 1.25 number is understated. Perhaps... in a dive, with a tailwind...
An ideal vector for a first strike? Nope... the flight envelope of the Lancer is very different from a SR-71. I'd much rather have a SR-71 flyover than a B1. Though, it was quite neat at the OshKosh Airshow a few years back... in the morning humid air, curls of condensation whisping off the top while performing a banked turn...

Though of course the fly ash and the tons of debris produced by coal burners is more radioactive, per energy produced, than that from a nuclear plant. Nuke plants are just generally about a million times less entropic in their output of nuclear materials, allowing for convenient disposal, as soon as politicians remove heads from tails.
At first glance, and with recent reports of NASA trying to bring old technology out of mothballs, I really thought this could be the same Project Orion researched in the 50's that relied on dropping nuclear bomblets out the ass end of a rocket to propel it forward, with a giant shock absorber to smoothe out the propulsion http://en.wikipedia.org/wiki/Project_Orion_(nuclea r_propulsion)
Too bad it's not. I mean, if it was, it would never make it off the ground anyway with all the nuclear fear in the world, but it would at least show that NASA is again looking forward, possibly resolving issues with that concept (possibly having it as a second or third stage, once the ship leaves the atmosphere, ionosphere, magnetosphere, what have you.
I'll hope you mean in parallel on your drives. Peltier in series are not befitting that application unless you live in an unusually hot house, or have drives requiring cryo conditions.
Placing peltier patties in series decreases the amount of heat they can move, but obviously increases the temperature differential, but only if the stack is properly designed. It is very easy to put two peltier in series and have worse performance than a single device. In your case, with a non-static system (i.e. the hard drives are actively PRODUCING heat that you wish to remove) heat handling seems more imprtant than massive temperature differential. In thermodynamics, there is no free lunch... your secondary peltier is not only moving the heat away from the drive, but has to struggle with the heat it produces (however much electrical power it consumes is heat) as well as the first stage cooler.
To optimize a multistage thermoelectric cooler, a rule of thumb is that each stage should recieve 1/2 to 1/3 as much current as the previous one. This roughly translates to an equivalent voltage ratio, though as the temperature and temperature delta change, the silicon has different resistances, and the Seebeck also changes the apparent resistance.
In a PC, if you really want to do multistage peltier patties, and assuming they are 12v devices, you would notice an increase in performance (i.e. less heat coming off the hot side, and a colder cold side) if you were to connect the hard drive peltier to the +5V rail, and the heat sink peltier to the +12 rail. This is a very crude system, but definitely better than running both on +12.
I still maintain that the coolers in parallel are preferable for nearly any computer usage. You have a metric library of congress of BTUs (slashdot measurement) to move quickly. Stacked units do this poorly.
I have some data at home to determine near-optimal steady-state stacked configurations. Google is a help too, though sorting through the deep research and crackpot FAQs is rather tedious in this realm.
You mean that as a joke, but it is not entirely without merit. On any system with 192MB of RAM or more I generally do not use a swap partition, since it is not needed as long as you dont go bonkers and try to load up the GIMP and a VM and OO.o and all the default active services or daemons.
Some apps will not run without swap space - not that they actually use it - just that they refuse to run without some. Create a 2MB swap ramdrive, and problem solved - just to make the programs happy.
I mostly use a laprop retrofitted with a Hitachi microdrive in place of the hard disk to save power. It sips power, is dead quiet, and produces almost 0 heat, but is slow as ice melting. Program loading is almost bearable, but once loaded everything's fine. Hitting swap on it would be disastrous.
If I need to use a memory hungry app (huge image editing, etc) I use a different machine.
AOL version 2 was not necessarily bad. It performed its function well, was relatively stable, but had not yet opened up the intarweb to the masses.
With Version 2.5, which started doing funky things like making virtual devices to simulate internet access to other applications, my impression of the service went kaputnik. Not malware, necessarily, but more than enough to hose network settings and make itself a nuisance, and nearly impossible to uninstall.
I had free AOL up to version 4 as a beta-tester of the client software, at which point they stopped providing any incentive or free service to their beta people. Yep, not only am I going to pay for access, but I'm going to pay for the 2 hours of time every week or so to download the latest 8MB client. I think not! Goodbye Steve Case!

"DC tends to cause a convulsive contraction, often forcing the victim away from the current's source."
Riight... Whichever muscle in a muscle group is stronger presents the dominant force in a convulsion. In the human arm, the gripping muscles are far stronger than the hand-opening muscles. DC or (low frequency) AC, the result is the mostly the same - the hand will grip. If that grip is responsible for the zapping, good luck. DC is worse than AC in this aspect.
That said, fibrillation is more of a risk with AC than DC, but at power distribution voltages or end-user voltages (220, or in the case of us 115), the difference in damage and risk is negligible.
I have a drive controller card, with no chips on it, 2 16k boards of bad memory, the bad power supply, and several modems/serial/junk memory cards. Have a functional 8080 and Z80 ZPU processor board (after purchasing a new Z80 chip for cheap).
For memory, I intend to take one of the scrap memory boards and put a modern 128k*8 NVSRAM chip on it, with the requisite logic and stuff, with half of the chip going unused. bank switching is possible, but i don't think necessary.
Also, plan on modding the boards to accept 5, 12 volts from a standard supply rather than having separate regulators.
assuming the serial IO boards still work, the rest should be all coding.
In soviet Russia, your children can be breast fed by you.
However odd it may be, human males have the ability to breastfeed, though since pregnancy is impossible, most people do not realize it. Granted, I am not sure the feasability or usefulness, but it is physiologically possible in certain cases.
I think it is time to dust off and revive my trusty ZPU powered Altair, finally complete the power supply transplant which it needs, and have it start hosting my website. If the website cannot fit in 64kib RAM with the HTTP daemon and SLIP stack... then perhaps I'll be forced to finish the SDIO mod so I can use some microSD as the epitome of anachronism.
Then again, the WRT54G it would be SLIP connected to is much more capable of serving pages. It's just not fair:'-(
