OK, lets be honest here, before I even start this one. I have no idea how it really works. The Aimulet LA is a handheld audio communication device. It is made of molded bamboo and requires no batteries. Here is an explanation of how it works:
With the device pressed against your ear, you stand over a designated area. On the floor are LEDs, which then transmit a signal to an array of spherical micro solar cells (called Sphelar by manufacturer Kyosemi). The Aimulet LA then transforms this signal into audio which is fed to your ear via tiny speakers, all without batteries. Potential uses include museums, zoos, botanical gardens, etc.
Personally I just like the design, the green aspect, and the thoughts of making molded bamboo furniture.
