    Air equivalent of rail gun possible?

    Hmmm, not sure if I read that right, but it looks like that ionocraft uses slightly different principles. It looks like the movement comes from the ions moving from the wire to collecter. The picture shows the wires as being above the collector. So they would move in a downward motion...

    Air equivalent of rail gun possible?

    If a rail gun works by having an object that moves along a path, where either side has opposite charge, could that same principle be applied in air? I am not talking about an ion thruster, that already exists. I am saying, if wasting energy was not an issue, could it be possible to charge the...

    Magnets strength/repel, total movement?

    That's what has me confused. I think the main issue would be getting movement while being attached. The equivalent scenario that I am looking for would be this. If something has a mass of x, and can theoretically throw part of it's body in a given direction, at a set force, to achieve...

    Magnets strength/repel, total movement?

    Like that, but with a chain between the people. two magnets connected together. Held at an initial position where they will repel each other. But limited in that they can only move in one direction. So (wall) (magnet +++) string (+++ magnet)

    Magnets strength/repel, total movement?

    Thanks, that is what I thought. So... if two magnets are held in a position of repulsion by some device, and the device restricts movement in one direction but not in the other, would it move?

    Magnets strength/repel, total movement?

    Hey guys. Not a homework question. If two magnets have the same friction, same mass, etc. But have different strengths. and they are arranged so that they will repel each other, how will they move in relation to their starting points? Will they both move 1/2 the distance of the...

    BEd degree - magnetic generator - help with design

    Could have sworn I uploaded a pic. I am changing my design. I've got a one phase 20 pole generator I'm working on. The windings will be perpendicular to the magnets in a circle. So the magnets will run directly over top of the windings. Alternating N/S around the circumference. Similar...

    BEd degree - magnetic generator - help with design

    One thing I am thinking of is using my 4 magets set in a circle. With armature on the inside and on the outside of the circle. it will be a pain to build, but I think it would have a more steady flow and have less interference. I could be wrong though. If I set them all together such that the 4...

    BEd degree - magnetic generator - help with design

    Hey guys - I am doing my BEd degree. I'm going to get this out there right off the start because it will save a lot of issues. Please don't take this the wrong way, it's simply the truth as I know it. I am doing my Bachelor of Education, to be a teacher. As a teacher, based on my 'teacher...

    Help me find the shape

    I have noticed that Cayley Graphs allow for Arrows, but only allow one going out and one going in. Does anyone here know of a theory that allows for set number of out arrows and set number of in arrows?

    Help me find the shape

    Doh!... Wasn't thinking. The issue comes up that one A is actually existing as two. So over all the vertex would still have A=B. which doesn't work. Back to the drawing board. Anyone know of geometry software that could try to calculate that?

    Help me find the shape

    ya, that's the way it's looking. Keep in mind this can be in any dimension. 2, 3, 4,5. just as long as I get more vertexes with more A than B. A-----A could be possible, assuming the end result was still the same. Same with B-----B. each vertex should look like Let n < m Axn Bxm...

    Help me find the shape

    Hey guys. I am trying to find a shape that suits my needs. The amount of vertexes can be any, but the fewer the better. The edges are special in that each end has an A or a B. like this A------B I need the vertexes to have more A than B inputs from edges. I need all vertexes to...

    Non-uniformity of the universe

    ya, my bad. I meant sphere when I said circle.

    Non-uniformity of the universe

    I used the term infinite to illustrate what happens with odds when played out over time. Your use of the term infinite takes out the obvious, and puts it in another context, for the sake of argument. If that is your goal, then congrats, you win! Clearly I do not need to roll two die an...

    Phase cancellation of light - Is it possible to make light disappear?

    You are not looking for a specific change. you are looking for complete change. It's easy really. Refract all light so that it's either higher or lower than the spectrum of human visibility. No calculations are needed. It does the job of canceling it out, without actually thinking about it...

    Forces in a circle from similar charges?

    So, can anyone clue me in how that could be set up to actually rotate? The only way I can think of, for sure, would be to have an outside force that had a controlled switch that would turn on and off as the ball was past the zenith (probably the wrong word) so that it would controllably push...

    Non-uniformity of the universe

    true, there are 'similar formations' in the universe. However, the odds of some formations are more likely than others. The odds, over an infinite amount of time, will create a universe full of formations (or 'empty of' if you include distance) whose quantity is related to that possibility...

    Non-uniformity of the universe

    I could see it being uniform if there were just one 'big bang'. But there's other bangs going on. Constant contracting and expanding of space and energy. This has been going on since the universe began. Galaxies and solar systems form and collapse all the time. My assumption, would be that the...

    Forces in a circle from similar charges?

    Another point, two balls would move in opposite directions with the same force. I wish I knew how to draw this out. haha.

    Forces in a circle from similar charges?

    Why is the energy of conservation not violated? That's what I'm trying to figure out! haha. I know with the fan/sail concept the fan pushes air, > into the sail. The sail wants to go the direction the fan is blowing, but cannot because the act of taking in the air pulls the boat back with the...

    Forces in a circle from similar charges?

    Yes they would move apart. But if they are attached and share the same pivot point they could only move in either a counter clockwise or clockwise manner. Maybe my description was bad. Here's a picture. Assuming that these were all attached at that middle point and could rotate freely...

    Hydro-power output question(s)

    Water can generate power in more than one way. Ideally, to get the most power out of the water you would utilize as many methods as possible. Kinetically - water falling is used to create energy. Temperature - differences in temperature, costly to get it to work, but it could be controlled...

    Forces in a circle from similar charges?

    Hey guys, New here. It's been a while since I've done any physics. I've been playing around with some mental work in my head and I am trying to figure out why something doesn't work. I know it shouldn't work, but I can't figure out the why. What I am talking about is utilizing similar charges...
