Abstract
An apparatus in the form of a cell for powering an electrical device, such as a light source, that includes a first electrode generally in the shape of a rectangular metallic strip; a second electrode generally in the shape of a length of metallic wire wrapped around the first electrode; and a conductive absorbent material wrapped at least partially around the first electrode.
Claims22
An apparatus comprising:
- a first electrode generally in the shape of a rectangular metallic strip and being a first metal;
- a second electrode generally in the shape of a length of metallic wire wrapped around the first electrode and being a second metal that is dissimilar from the first metal;
- a conductive absorbent material wrapped at least partially around the first electrode;
- a light source electrically connected to the first electrode and the second electrode;
- and
- a shroud surrounding the first electrode, the second electrode and the conductive absorbent material, wherein there is not a complete barrier between the shroud and at least one of the electrodes.

An apparatus comprising:
- a series of one or more cells each having a magnesium anode, a copper wire cathode, and an absorbent conducting material such as a paper barrier between the anode and the cathode;
- a light source connected to the series of one or more cells;
- an opaque plastic shroud having a length, a width, and a depth, with the depth being less than either the length of the width, the shroud also having a top layer and a bottom layer, the shroud also having an opening proximal to the LED partially through the top layer and partially through the bottom layer;
- and
- a plurality of circular openings extending through the top layer and permeable to the absorbent conducting material.
