Hi, I recently downloaded a video where a guy, I forget his name, has a small yellow car, running down a track on top of a clear plastic top, setting on top of what appears to be permanent magnets. Someone introduces the video by saying "this is a one-directional, 32 inch, v-track with one gate." then he lets go of the car and it races down the track. Does anybody know what I'm talking about?
I got the video and a few others here... http://www.fdp.nu/shared/manager.asp?d=files%5CCalloways%20Perendev%5C Anyway.. Does anybody know if this guy is using permanent magnets or are there electro-magnets involved? And if it's all permanents, does anybody have plans on how to make this device or have you made one yourself? Thanks in advance!! Anthony
