Abstract:
A mold battery comprising:a. a mold member, having generally a planar shape, having a near edge and a far edge, b. an axle having a near end and a far end, which is rotatably connected to said mold member, wherein the near end is near the near edge and wherein the far end is near the far edge, c. a first wheel having a first outside diameter, said first wheel fixed on the near end, and d. a second wheel having a second outside diameter, which second outside diameter is substantially equal to the first outside diameter, said second wheel fixed on the far end, whereby it necessarily follows that, if the near edge of the mold member is moved by rolling it on the first wheel a first distance, then the far edge moves simultaneously on the second wheel a second distance which is substantially equal to the first distance.
