Rotating Asymmetric Capacitor

Using the same principle as antigravity lifters.

Most techno crazed people, after seeing a lifter on the web, will immediately jump in their cars to go and buy some balsa wood and contemplate which VGA monitor will be sacrificed as the 30 000V power source. Below are a couple of pictures showing how you can see the thrust effect without going airborne (as most people's lifters end up broken before the first flight). This demonstrator literally took about 30 minutes to build. I used readily available scrap material and 2 part epoxy glue to build it. Another advantage is that weight is not that big a problem the see the effect. So lets start.


I used an empty IC tube, but any long non-conductive piece of material will do. The bearing I got from an old 5 1/4 inch floppy drive. I stuck the part that usually makes contact with floppy in the centre of the tube.


Let the glue harden before you continue, otherwise the bearing might dry off centre.


Close up of picture above.



For the large part of the capacitor I used a CD (2x, one at each end). I reckon a non writeable CD, preferably Britney Spears, will work best :-) You will now glue the CD dead centre on the ends of the tube.


Make sure that the CDs are equally spaced, which should be the case if the bearing is in the centre of the tube and the CDs are at the extremes.


Below are the 2 CDs glued at the ends of the tube. Again let it harden for a few minutes.


The ground connection is connector on the bearing. From the bearing connect it to the CDs by drilling a hole and connecting the wire through it. Do this with both CDs.



Make a circular cut-out from normal A4 paper. The radius needs to be larger than the CD.


Next you will need transformer wire. From what I have read you will need a thin gauge. The thinner the better, but I will have to check that out. The wire I used is 0.05mm thick. You won't need a lot, depending on your 'tube' length about +- 1m. You can use the thin wire from a disassembled mains transformer.


Glue the wire on the edge of the paper and let it harden.


Glue the paper to the CD, making sure that the spacing is uniform between the CD's edge and the wire (on the paper).


I used a pen as the way to connect the 2 wires to as well as to attach a piece of foil to. The foil must make contact with the wire. Use a soldering iron or lighter to burn off the enamel from the wire.


Connect the HV power supply to the foil (which must connect to the 2 wires). At this stage please NOTE: If you don't know how to work with high voltage, under the influence of any drink or drug or consider yourself stupid, clumsy or accident prone then get an expert to help you. Remember those sparks can travel quite a distance and will take you out...as in dead.


Here you can see my setup. I am operating this in an area away from my PCs and other sensitive equipment. When you switch it on everything gets charged. You can blow your PC and not even know it.

Before you switch it on make sure that all the 30KV connections are away from ground. Any short and you will blow your PSU. Make sure you can remotely switch the power on and not by some stupid way of attaching the live wire to the foil.

Don't try and put a switch in the 30KV line. It will arch. Only operate via the mains switch.

If you switch it on and it starts arching then switch off immediately. Short out the 30KV connection to the ground connection to discharge any stored charge. To do this first touch ground and then connect to the 30KV point.

If successful the device will rotate in the direction of the thin wire.
