Claims

1. A charger for a device powered by stored electricity comprising:

an electromagnetic radiation source, the electromagnetic radiation source producing a beam of light that defines a central axis of the charger, the electromagnetic radiation source providing electromagnetic radiation to a storage element on the device, thereby charging the device; and

at least one magnet, the at least one magnet maintaining a fixed physical relationship with the device when engaged for charging.

2. The charger of claim 1, wherein the electromagnetic radiation is a substantially monochromatic light.

3. The charger of claim 1, wherein the electromagnetic radiation source includes a diode-based light emitter.

4. The charger of claim 1, wherein the electromagnetic radiation is laser light.

5. The charger of claim 1, wherein the device is a machine capable of executing instructions that specify actions to be taken by that machine.

6. The charger of claim 1, wherein the device is a wearable computing device.

7. The charger of claim 1, further comprising a protective shroud around the electromagnetic radiation source, the protective shroud configured to align with the device during charging.

8. The charger of claim 7, wherein the protective shroud encircles the central axis of the charger, so that the shroud is equidistant from the beam of light.

9. The charger of claim 1, wherein the magnet is a permanent magnet.

10. The charger of claim 1, wherein the magnet is a rare earth magnet.
