1) I am not an Engineer, I am a chemist. 2) My point above was to refute someone elses point that pressure does not change with temperature. If you think it doesn't, prove it. 3) And if you don;t believe me that the solubility of CO2 in water increases as temperature decreases, maybe...

wrong forum.

and don;t forget it has to be simple enough to operate that even cleetus the hillbilly can protect himself

wouldn;t you still have to eat enough real food to provide sufficient calories to provide energy for your bodily functions? Seems like you are saying eat just enough to meet your vitamin requirements, but you still need othjer stuff to convert into actual ATP. Seems like your saying eat 1 date...

yes, but first the enemy would have to know what signal is being used to control the system. Jamming is not as simple as filling the airwaves with lots of low level noise, its sually accomplished by pinpointing a known frequency and broadcasting at high intensity over that band. At least this is...

US PAtent 6819531 to Shiroishi teaches a hard disk apparatus having a 50 MB/s transfer rate where the platter is spun at 25,000RPM. The recording density is fairly low (5GB/square inch) compared to slower drives (50-100gb/siquare). But it is fast!

Couple thoughts on this: 1) The targeting and tracking system for a tank based anti-ballistic system would have to be ridiculous to be effective. The targeting/tracking system for this is well well beyond most if not all current systems (the system would have to track hundred of tiny fast...

see below for much better (and certainly more correct) anwer then I gave. Hey! I'm a chemist qith a background in applied magnetic materials..I said I wasn't an EE. Thanks for correcting me guys. :o

Typical hard disc platter composition: Substrate: glass, polycarbonate, NiAl alloy, or Titanium alloy (only the nickel would be "toxic" because of the heavy metals, but the wort you'd exerience would be nickel itch unless you ate the disc LOL) underlayers: typically Chromium and/or a Cr...

Dude I think he was referring to the armed UAV's used in Iraq right now, i.e. the predator UAV. Take a chill pill. :D

simple, because humans have been killing each other since we evolved, and probably before then too. Also, I recently read something about a polymer that rapidly (nanoseconds) hardens when exposed to a point source impact (i.e. a pencil type, doctor blade, or bullet). Its supposedly very...

The reason hard drive platters cannot be, or more accurately, the reason they are not spun faster then they are currently is two-fold: 1) Microwaviness (that is literally what the property is called in the art, I didn't make it up) of a hard drive platter has a direct impact on how fast the...

also, I recently saw a 600GB commercial HD for sale, so the terabyte drive is not terribly far off.

Server storage for one. (2 huge capacity drives in Raid 1 might be more cost efficient then the 20 or so in a current server rack. DVD audio for two Next generation games for three (average install now is ~6 GB, 5 years from now it might be double or triple that And of course, not to...
