Great muffler. I guess this is the future, I really wonder how much energy they use c/w petrol engines when you consider the necessity to recharge all the time. Unless the power is coming from nuclear generation I guess they are using dirty coal or gas fired generators. Of themselves I would think the process is just sending the pollution down stream a step or two. I would miss the etherial pulse and sound of a real petrol engine very much. It is very much part of the experience imho.
