Problem[edit | edit source]

Most motors used today use magnetic fields to create the motion. But it is possible to create motors that run off static fields. Why is a stationary electric field not used as much as a stationary magnetic field?

Conceive[edit | edit source]

Design[edit | edit source]

The designs appear to be easy to create from the videos.

First attempt worked

But the spinning bottle bounced back and forth. Next attempt used metal and bearings to stabilize, but failed.

  • Step 6: Created a "dimple" in the metal bottle cap used with the middle bottle (with a dull nail).

  • Step 8: Screwed the outer two bottles to the wood with a long rod, duct tape, and plumbers putty. Cut a metal rod ,similiar to a coat hangar, filed the end to a point (for a better spin), and used for the middle bottle.

  • Step 9: Taped a wire to each outer bottle and pointed them towards the middle bottle. Taped a small wire "loop" to the bottle so it could be hooked up to an electrostatic generator.

Implement[edit | edit source]

Try to build each of the designs in the videos.

Operate[edit | edit source]

The goal is to operate with a minature whimshusrt machine built from a soda bottle as in one of the videos. This way an external whimshurt machine is not needed.

Demo[edit | edit source]

Next Steps[edit | edit source]

  • Get the existing static motors working again
  • Build new soda bottle motor with soda bottle generator
  • Build can version
  • Build cyclotron
