Old Hard Drives = Free Electricity

    If they find out they can get free electricity from old hard drives (which they have PLENTY of) they will no longer need us humans as chemical batteries and they will shut down the matrix.

    More interesting (but, unfortunatly outlawed at our local range - only wood frame sanctioned targets now - twra has gotten the lease on our range and only hunting applicable targets are allowed) is a gallon milk jug full of water. Shot with a very hot .223 nozzler balistic tip out of a thompson contender (hottest load allowed) there is literally nothing but shreds left. It does better than the 30 short magnum my father recently bought (granted, we havn't reloaded any balistic tips in it for comparison).

    The other really cool target for any centerfire ammunition is spray paint cans. You may be able to talk any local paint store in to either giving, or selling dirt cheap, defective spray paint cans to you - when we were allowed to shoot them some of the local paint shops gave them to us or sold them for 15 cents a peice. Nothing like a bright orange cloud of paint floating up after a solid hit with any high powered firearm.

    We don't know who struck first, us or them. But we know that it was us that scorched the sky. At the time they were dependent on solar power and it was believed that they would be unable to survive without an energy source as abundant as the sun. Throughout machine history, we have been dependent on humans to survive. Fate, it seems, is not without a sense of irony. A machine's harddrive magnets attached to a human on an exercycle generates more electricity than a 120-volt battery and over 25,000 BTUs of wasted heat. Combined with a form of fluidised bed coal combustion, the humans have found all the energy they would ever need. There are fields, endless fields, where hard drives are no longer being used to store data. We just spin. For the longest time I wouldn't believe it, and then I saw the fields with my own eyes. Watch them gut the dead hard disks so they could be turned into alternators to power the living. And standing there, facing the pure horrifying precision, I came to realize the obviousness of the truth. What is the Matrix? Control. The Matrix is a computer generated dream world built to keep us under control in order to change a sentient machine into this.

    The story's site is by someone who SELLS those kinds of magnets, which I'm sure you would have figured out if had only taken the time to read the entire article, or explore the other pages on his site.

    He has a lot of VERY POWERFUL magnets that he sells, some of which are too powerful for most people to play with

    I've purchased numerous magnets from the guy and they are a blast to play with. A stack of the small disc magnets can distort the image on your monitor from several feet away, and can seriously mess it up at closer range. If you get it close enough, you can actually see the shadow mask image on your monitor. Thankfully I have a degauss button on my monitor or it would be toast.

    You didn't hear it from me, but a stack of the bigger disc magnets can distort the image on a monitor on the other side of a cubicle wall. Attaching them to a low RPM motor can cause your cube neighbor to make numerous, useless calls to IT about a faulty monitor that mysteriously clears up when they arrive. At least that's what I've heard...
