Yes. I'm glad you asked. The 2.0 emitted about 3 khm per second less than the 1.5. This may not seem small, but lets not forget that the sound of a kJ is a fraction of a second, less than it would take you to blink an eye.

This is a good question. Where does it "spring" from? I buy bottled water, or the refillable 5gl ones. So I understand that my water isn't fileted by a spring. But why does "Spring water" get a different designation than everything else? And does spring water get filtered, and if it gets filtered, but not distilled. Does it have parasites and shit? I'm not allowed to drink any water unless I boil, or something. Yet spring water is good for you...
