    Grounding wire in household circuitry?

    Ahh, yes. I see your point, Jim. You are correct. But keeping the system isolated is the problem. The idea, here, is to assume that the worst could happen. If a tree were to make contact with with the transmission lines, or any other form of ground fault should occurr, the system would not fail...

    Is it possible to reflect light off of air?

    You don't really need particles scattered in the air. atoms themseves can scater or reflect light. Earnst Rutheford showed this with his thin gold foil experiment. Air, of course, is much less dense, but of course there is miles-and-miles of it, depending on the "experiment" so the likeliehood...

    Why is there a seasonal cycle of CO2?

    The Northern cycle should predominate, as there is greater landmass there. There is a lag-time in the data like the cosine and sine wave due to the time it takes to reach equilibrium.

    Grounding wire in household circuitry?

    The statement that you must touch two wires to complete the circuit is false! The ground wire is there to create a path of least resistance, if in fact you do touch the housing of your washingmachine and a wire is loose inside. You, being of higher resistance are, then, not the path of least...
