Magnetic Force.

New Blog \(^.^)/
Well based on my reaction above, I highly doubt anyone will take this blog seriously; granted they take the time to read it, let alone find it. I chose to write in here for two reasons: one, I need a vice from all the studying I have been doing; and two, I haven't written in here for a while so I will jot down some of the things I have thought about since my last posting.  For starters, let us look into the idea of a better methods on getting into space.  I am no "rocket scientist," nor do I believe I will ever be able to achieve the mathematical skills that individuals in the fields of Astronomy and Physics because I will spend my time studying medicine, and frankly, I hate math.  Aside from that, the current method used to get into space is by using "rocket fuel" to propel the rocket along the rotation of Earth in an upward trajectory to escape the gravitational forces exerted on the rocket (uses less fuel, rather than purposely fighting against air resistance and blah blah).  I know I simplified it a ton, and I may be wrong, but this is just a general overview to propose what I am thinking/what is being developed currently.

Among the forces of nature that exist, gravitational force is one of the weakest.  One of the stronger forces is actually electromagnetic forces, which account for many of the interactions that we perceive to be everyday occurrences; One of the better examples being friction.  When you slide a box across the floor, the friction can be thought of the interaction between the electromagnetic forces between the two objects (floor and box), which inhibits the movement of the object.  This got me into thinking about a different method of transportation via magnetic or electrical forces, both of which are capable of inducing a push-pull mechanism based on their polarity.  [Right now I will apologize if a lot of what I write doesn't make sense, I am currently writing this half-asleep]  Assuming that we can make a magnetic body capable of orbiting Earth without being attracted towards it (If it were attracted, it would result in a huge object plummeting towards Earth's surface due to the attraction), We may be able to utilize the magnetic pull created between the interaction from the rocket to the magnetic. Of course this would require a higher elevation for the rocket such that the magnetic pull from the rocket is greater than the pull that is exerted by Earth, and there needs to be a method to overcome the gravitational acceleration exerted on the rocket.  There may be a way to do this. Assuming that this situation takes into account that the pull of the rocket due to the magnet does not entirely result with the displacement of the magnet from its original position, which would affect the magnetic force between the magnet and Earth (strengthening it since force increases as distance between the two objects decreases), an increase in the polarity of the magnet as a function of distance may work.  Beginning as an object not polarized, the rocket remains at rest since no outside forces are working on the system aside from gravitational force.  Now, when the rocket is polarized and the magnetic force creates a pull on the rocket in an upward direction, the net forces working on the system (Newton's 2nd law) now are gravitational force as weight, and the magnetic force upward due to the attraction to the magnet.  When the gravitational force is overcome (assuming all other forces are negligible), the rocket will begin to accelerate upward since the gravitational force on an object decreases with altitude due to the decrease in gravitational acceleration.  This alone will not lead to the propulsion of the rocket into space, since the rocket will be moving rather slowly.  That is why I suggested the magnetic polarity of the rocket increases as a function of altitude. As gravitational acceleration towards Earth decreases with altitude, the increase in the polarity of the magnet on the rocket increases the attraction between the magnet in space and the rocket, thus moving the rocket upward faster. Approaching the magnet, the magnet on the rocket increases in magnitude creating a stronger force between the two objects which creates a velocity larger in magnitude.  Just as the rocket is about to collide into the magnet, we can shut off the magnet which will decrease the attraction between the rocket and the magnet, as well as providing the rocket with a a velocity which is large in magnitude. Try and experiment it with a large, strong magnet and a smaller magnet, and see what happens between the two as the distance decreases.  You will find that the magnet speeds up exponentially due to the increase in the magnetic pull as the distance becomes smaller and smaller (this is as a function of the inverse fraction of the original radius squared). Now we also need to assume that the rocket does not become magnetized since it is made of metal, and magnets tend to polarize metallic objects.  If it is possible, then this would be an alternative to using chemical fuels to propel rockets from the surface of Earth (which is where the bulk of rocket fuel is used).  Since the rocket is now in space, it needs constant force applied in order to move forward due to the rocket's collision with particles in space  or it will stop.  But I'm too tired to write down the ideas I had for that since I am tired and want to write about something else.

Last thing I'll write for tonight is the formulation of a renewable energy source.  Right now, there are solar panels that convert electromagnetic radiation from the sun, which is converted by solar cells into a form of energy which can be used as electricity. We also have hydroelectric systems, which include the wheel which converts the push of water molecules in a river into energy, and the energy from waves into a form of energy we can use.  Then there is also wind turbines that use the energy from wind to spin the turbines, which act similarly to the wheel in the river, to convert wind energy into mechanical energy that we can use.  Lastly is nuclear energy, but I don't want to write about since it would take too long and I am tired.  My idea is that we can use a form of renewable energy the mirrors the Kreb's cycle/Electron transport chain, in that energy is input to yield more energy output.  Think of it like a ball starting at the top of the machine, and as it rolls down, its force is transferred from the ball to collide with a button that compresses a spring (there is a "trap door" near the button, with a spring that compresses when the force due to gravity overcomes the upward force of the spring, which allows the ball to go down so that it can begin the cycle again).  The potential energy within the spring can be converted into mechanical energy, and part of it can used to begin the cycle again by moving the ball to the top of the machine again via a conveyor belt. For one that mirrors the electron transport, it is much like the same mechanism, but there is more than one, and the ball rotates the wheel. Just one of my thoughts.  Too tired to write, logging off.
