    Giving them deposits of 380 and loans worth 280

    as you say, they are paying interest on $380, getting interest on $280, so they do have to pay that money back, and thus get it back.

    Once you multiply it out to the $2000, thier is just $1 out in someones pocket to be spent of the original $95, granted from that original $95 the banks are paying interest on $2000, and getting paid interest on $1800 (granted some of that money is really low interest, IE you checking account may draw no interest, and their only paying you in paper work, and services for your money.)

    That still leaves the bank needing to get back their credit card debt in order to pay their creditors, but since they are making the difference in interest rates on more than the original $95 it happens quicker than otherwise expected.

    while aluminum will deform in failure (converting most of the energy to heat) carbon fiber seems more likely to shatter.

    of course their is a downside to most changes.
    by deform, you mean yield so, yes if you exceed the limit of carbon fibre you likely have snapped, where as aluminum, you have destroyed the structure of the frame. So if they both exceeded this limit at the same load, the aluminum may allow you to make it through one event.

    For this to be obviously safer, you need:
          1) the yield points would have to be very close.
          2) it must be a single yield event (not repeated yield points, leading to a quick fatigue failure)
          3) you must know the event occured so that you will replace the yieldied aluminium part, before the next event.
          4) the yield event would still have to be in the yield strength of the aluminum, and not exceed it to the point of failure.

    I think that is the issue, all of these are false. Carbon fibre has a much higher yield point, the aluminum wings constantly need inspected for fatigue cracks, and with each cycle they become closer to the point of failure.

    With the carbon fibre, as the wing bends, it is probably designed to self limit the load. Since the aluminimum cannot survive the same amount of movement, it cannot self regulate (it bends, which makes it hot, which makes it softer, which makes it bend more which makes it hotter and softer,...)

    of course it takes alott of energy to bend carbon fibre also, so it is releasing energy as heat as well. Granted aluminum is a much better heat conductor, so it would naturally transfer that heat better. But carbon fibre is known to stay stronger at high temperatures than aluminum.

    I've always heard that it takes more wire to set up a good wireless network than it does to set up a wired network.

    guess it really depends on a number of things. We have found that it works best for our critical deployment (and I do mean critical) that you need a seperate backbone than your network. You can setup a bunch of repeaters that are not wired (In AZ, their solar powered, battery backed) but then when you get something at high bandwith, the users at the end of the line ends up less reliable (data shaping and the like is where the best installers overcome this.)

    So the extra wiring your talking about is for the backbone to the AP's. Since 802.11a hasn't really taken off in WiFi devices. What we did was ran a 802.11a backbone with directed antenna's that was eithernet connected to the 802.11b access point (3" ethernet cable, not 300' fiber optic)

    That actually cures alott of things, since the 11.a backbone is higher bandwith, and because of higher gain antennas (fixed destinations) their is not a significant difference in bandwith to the last AP, and a minimal number of hops, and all the things used for discovery, authentication, etc, etc can be mostly disabled on the backbone (assuming you want your main WiFi to be open to discovery.)

    Of course you need more power to do wireless, so if thats the wiring you mean, then absolutly.

    assume the small motors inside the wheels are gear free.

    actually almost certainly false. I haven't actually seen any electric motors, of the size fit for vehicles, that make anywhere near the torque of a gas/diesel at low rpm's at the motor shaft. For instance we (company I work for) make both electric, and mechanical drive trucks behind 2000+ HP diesiels. The electric Truck has a fixed 50:1 gearing reduction where the mechanical drive is around 35:1 in first gear.

    It only makes sense, electric motors are well known for making even torque across a wide RPM range, hence no need for multiple gear ratio. Since torque*distance=power (or torque*rpm with fixed gearing), a electric motor of the same HP as a gas motor is going to have a-lott lower peak torque than a lower RPM turning diesel (assuming the electric turns at higher RPM.)

    As for no need for brakes, in the Generator world, torque=current, voltage=speed, so at low speeds you can't run the brakes in generator mode any where near peak torque, so you would have to run it in power mode to plug brake to a stop. Otherwise you have to run insane current, (is your motor to be made of super conductors?) at extremely low voltage, or change winding configurations dynamically.

    similar to brake mode, you need insane current to get extreme torque, and since power = torque*rpm at 0 rpm you got 0 efficiency so you really get your motors extremely hot if you run them at (or near) stall RPMs for any length of time. So although it may makes good (maybe 60% of peak) torque at stall, you can't use it for long.

Or you can combine arrays with LVM so if you had 250GB+3*500GB+2*1TB drives you can setup a 5x500GB raid 5, and a 3x250GB raid 5, and combine them into a single volume with LVM giving 2.5 TB of RAID storage.
