well if there was a magnetic field underneath, it would be enough to cancel out gravity and then some.
and a nother question... do you think there is the inverse of this? A usbstance that is solid until a magnetic field hits it? then ti becomes soft or liquid until the field is removed?
Perhaps if you wrapped yourself in a suit made out of very diamegnetic substance...like bismuth(or however you spell that) Then you could apply a powerful magnetic field underneath you...and up you go! Much easier than relying on your own diamagneticism..
This happens to me occasionally, i sort of become aware of existence. I notice that i am on a massive planet, i notice that i am miniscule compared to it. I can see everything as it happens on the whole planet. I gain comprehension of the universe. Often time, these brief periods of enlightenment are followed by a strong desire to create and to think. Its like my inner genious gets awoken...i dont know, it seems similar to what this fellow described.
or in say a base 3 math where 2 + 2 = 11 since the highest number they can have is 2 (so there are 3 numbers, 0, 1 2) there so when 2 + 2 adds up to 4, the 4 is 11 in base 3, 5 is 12, 6 is 20, etc
huh? Parts of light can move faster than light, which, i think, sets the scene for FTL communication, but everyone disagrees with me... I dont see how it could just have a system of binary flash to work... but w/e i probly just dont understand...
it already exists, i just was doing more research, its called rheology. Its basically a study of things that change viscosity like these fluids, and also non newtonian fluids, like the shear-thickening fluid we talked about. Im surprised we dont see more aplications of this stuff...it seems very useful... Maybe ill have to make some cool usages of it!
This is very intresting... Now what if you had a powerful magnetic field in the shape of a dome? Then from a helicopter dropped magnetorheuoulogical fluid on it... Would it build the dome? Actually..i think youd have to apply the bottum parts first...or else it woudl jsut fall down lol Idk...it seems you could use it for something like that, like portable fluid buildings or something... You could use the electric one in robotics, as long as an electric current flows through it its hard, but when it stops, it becomes liquid, or soft at least...i can see multiple applicaitons, from grasping hands, to joints that dont need many moving parts, just electrical curents...
or you could make a floor that was on off liquid, just apply eletrical current or magnets or pressure from teh bottum (depending on what it is made of) and you get a solid floor! Take it away, it goes to liquid! It seems so cool!. you could use it as a way to protect things, place it in a special container of this, and then you apply pressure, the liquid solidifies to a solid, completly protecting what ever is inside!
Or you could perhaps make a wheel that turned itself sort of (idk just thinking of aplications) YOu have a large blob of perhaps magnetorheulogical fluid with a sphere in the middle, that has pwerful, horse shoe shaped (to make sure they face the same direction) magnets. By turning these electro magnets off, you could melt and resolidfy areas of the sphere, melt the front area, it becomes liquid and the whole thing rolls forward, then solidify it when it gets under it. I wonder if that would work... To stop the fluid from being completley lost, you could turn the magnetic field off somewhat, resulting in a soft but not entirely liquid portion of the tire thing.
How hard does this stuff get? You perhaps could use it for bomb containment. Just roll one of these things over the bomb, and harden it! Im sure if it were big enough, it would contain it!
I wonder what other "Smart fluids" are out there... Are there any that contract or expand on the applicaiton of electric or magnetic fields/current? This stuff seems so scifi! I wonder if it is possible to mix the properties of these?
Oh and to science guys second post, about making it go around fast enough to generate signifigant electricity: Well assuming this did work, then you could easily have tons of them all turning the same turbine, so the interval between each ball turning a fan thing would be small enough that it would work, probably
Roy, the ball would be launched slightly upward upon exiting the ferrofluid (which has a consistency of about that of oil). Like science_guy said, the main problem i could see would be finding somthing able to pop out of the top enough to get over the hump, but dense enough to break back into the ferrofluid, im not sure what the surface tension would be like, but i might do some tests and figure it out when i get som excess cash (ferrofluid is a tad expensive, about 25$ for 50 ml). Im thinking perhaps a rubber bouncy ball would work, assuming it floats in oil(i dont know if it does). Ill do some tests, and see if it works!
