[QUOTE="Dick Rees, post: 22919, member: 16"] Re: 12v Eco project sound system Well, there's green and there's green. How green is it moving around large physical apparati even if it is nominally efficient at what it does???? You lose in logisitics what you gain in performance. Everything is everything, as the saying goes. Now if you want to give everyone the same sonic experience with a minimum "carbon footprint", consider individual receivers/transducers all tuned in to a low-power FM broadcaster. This is as efficient as you can get because 100% of the sonic energy is delivered to the user/listeners with none of the energy lost to the air. Use rechargeable batteries and charge up from solar/treadle/whatever. You could call it a WePod............ [/QUOTE]
