Here is a conceptual wireless stereo speaker docking station that works with a wide range of portable media players, and since it is a concept, why not go wild with its capabilities and leave the engineers to suss out the viability of manufacturing something like it in real life? The entire system is touted to be waterproof, hence making it suitable for use both indoors and outdoors. At the dock are lithium-ion batteries that offer more than enough juice for the stereo system to blast your favorite tunes for hours, and will rely on renewable energy sources like solar power, wind power, or hydroelectricity to help keep it juiced. The entire speaker enclosure was designed in such a manner to amplify sound, hence increasing its effectiveness in a room. Would you like to see this concept come to pass?
