energy crisis, army going around a city thats burning spreading what looks like oil on every bit of fire to stop it, sailors vs. soldiers, i create a device that expands teh center of the earth, the president orders it built and sends it on its way,
meanwhile.... space exploration... i'm sent off to the stars for some reason...

ok here's one...
ok so... button on a string, take that idea... when you have it moving, snap the center so the string is no longer attached, then move all the weight to the center
obviously not practical in a gravity field....
(two rockets... pointed so the flames dont burn the string... both pull a pre-wound string so the spacestation starts moving... then they cut the string....?)
for fun, 1 foot wide round piece of plywood, two razor blades set up where bicycle forks end... set your dick carefully to spinning fast then when the top of the spin is rolling away from you "chop" the string downwards on to the rope so the plywood disk is set loose at speed... please do not point at humans!

bike wheel ?
so i was waking up and thinking about merry-go rounds
4 kids who "pump" it can make it go faster than one adult standing on the outside and spinning the edges... its easy! you just go out... the all pull in... pulling in is pretty hard cause...it is
anyhow the thought crossed my mind "what if you did that with a bike wheel?" if you could pull all the weight on the outside of a tire to the center thn let it go out... pull in... ect,
how fast could you make the bike go? whats the top speed for the equation?
for that matter... how the heck do you DO such an equation...
Iout = Itorso + ½(2marm)r²arm + ½mleg = 3.6 kg m² ?
apparently the equation can be found in terms of a figure skater doing a spin
Angular Momentum Conservation
Angular momentum characterizes an object's resistance to change in rotation. The basic idea is the same as with linear momentum: moving things like to keep moving, and to change their motion we have to apply a force. If no force is present, then momentum doesn't change, ie. it is conserved. In the case of rotation, the force is called torque: when, for example, you pull the string on a top, you are applying a torque to make it speed up. Its angular momentum increases. It slows down after being released due to frictional torque. A spinning figure skater has a nearly frictionless contact with the ice, and there is little net torque on her body. Her angular momentum is nearly conserved.
Rotational Inertia
For straight-line motion, inertia is mass. For rotational motion, it's a bit more involved. It's harder to make a given mass rotate around an axis that it's far from than one that it's close to. The rotational inertia, or moment of inertia, I, of a single mass m rotating a distance r around an axis (like a planet around the Sun or a rock on a string) is given by
I = mr²
Note that rotational inertia increases as the square of the distance from the axis: if you double the distance of a mass from the axis of rotation, you quadruple the rotational inertia. This is why such a minor change such as a skater's leg position has such a huge effect on her rotational speed.
Rotational Speed
The other parameter of rotational motion is rotational speed, or angular velocity, . This is the rate of rotation, expressed in radians/sec, revolutions/minute (RPM) and other units. A complete rotation is 2 radians, so one revolution per second is an angular velocity of 2 rad/s.
Angular Momentum
Armed with rotational inertia and angular velocity, we can write the expression for angular momentum, L:
L = I
So, if angular momentum is conserved, and one factor like I changes, the other factor ( in this case) must change to compensate.
GAH!! ok so i don't understand the math behind this at all, still, designing a small push pull action for a weight on a sproket shouldn't be too hard right?

Hockey game, rink being used by skaters, Zamboni comes out and skaters clear off, we join the stands, it starts hailing we hold seat backs over our heads to keep it off i ask for a root beer, game over, i ask Amy if she wants to go to a bar
Suzanna is plating with a stuffed dog, Gregory game it to her, it has a red warning light on its back to warn her to stop thinking about Fred whenever she does think about him. Fred seems to have caused her some anguish in the past and Gregory, an English psychiatrist has trained her to ignore her fears rather than face them

this dream happened in kyuquot, i saw my cat, found 2$ under the walk and nearly got my head squished getting it, chenny was there with a hurt paw, pixel had found a mate, one of ginger's sons
(pixel is a cat, ginger was "the" original cat in my family life) found a fishing rod out by witch rock (theres a ancient native legend behind that rock, imagine a 40 foot high 10 feet wide then 30 long rock, attached to the ground, but ... its FLAT all around it... like a giant rock toe or something) i started fishing there were 7 lures on the line (illegal, unless you are native)
it was a fly casting ro, my Father built a bridge to the reserve, they were talking of building a disco bowling alley, someone got kidnapped by someone who had a lot of extra parachutes.
the misty river needed a new bow-line, by witch rock there was a game of basketball, very ironic since the rocks are unsuited for it...

HUGE scaffolding structure needs 1 more set of scaffolding extensions, we are off to get 2x4's HUGE white dog with gleaming silver eyes, many little dogs, my bro's typewriter, tent poles keep jumping out, i show them how to use a paper clip to keep the tent pole in place
i throw stuff to get the dog pack to run off but the silver eyed dog just stares at me, intelligently not challenging me on my own ground. earlier a guy wants to decide if i am native to kyuquot or a spy he takes me close to shore then pushes me into ankle deep water, a girl is diving out by the dock, 10 feet down she unscrews a light bulb, then goes back to her room, a devil is on the loose, someone prys up paving stones and replaces them with "holy" paving stones to give him hot-foot when he crossess them

two of my brothers and i are at grandma's house "picking" wives on bro picks a girl who has a child, the next bro picks one, the girl i was thinking of picking (Sonya?) is already 5taken, i tell my brothers i really am the one who won, cuz i don't have chains, I go upstairs and i grab my pack and try to decide what to take with me, too many books earlier i was doing olympic sports, i ran on an indoor sloped area

leah and her bro, i gave her a shoulder massage, dreamed i was moving to alkberta then back to bc
/18 /feb /2007
dreamed brad and i were friends again, (it was an afternoon dream)
/20/feb/2007
Dreamed of pirate gold, girl and a guy were trying to outsmart me

date unknown
Floor with a shifting pattern beneath glass, i dreamed i woke up and wrote the dream down however i seem not to have. the room was long and the door i wanted to get to was at the other end of the room with a red light leading the way.
Bad mustard, fluorescent apple juice, slices of tomatos 2 girls huge room monkey face gloves, care my scooter no more help from paint baller dream on thanksgiving Girl, Pie, alarm (sophia?) Sonya car that flies, healing animals / people get on the ferry with a bike

blog 1,
hi, so... i have a book of dreams i've recorded upon waking over the past few years,
i'd just turn till i found a blank page in the book, then write, i'd usually be groggy too,
the dreams are non-sequential, and due to interest in my imagination, i thought i'd put em online... supposing some author comes accross them and uses any ideas, i would like credit, and to be notified... i would be pleased to find my imagination put to use.., thank you.
