12/27   Anyone have experience with voltage regulators? Ie, it will
        correct under and over voltage back to 120v? I am trying to
        find one... Thanks.
        \_ Yes, they will do that. Is there anything more specific
           you wanted to knwo?
           \_ What particular ones have you used? How well does it work?
              Last night I measured 150v on one of my lines. Damn PG&E.
                \_ I don't remember the specific ones, but all the ones
                   I've used were IC's.
                   \_ Well, several questions come to mind.  What are you
                      trying to do that you care about the over/under voltage?
                      Assuming you're trying to do some ninja-EE trick, how
                      much current do you want to suck from the line?  The
                      answer is different depending on what you want to do with
                      the power.  Finally, if you are doing some kind of
                      project that requires homebrew AC regulation, do you
                      think you'll taste better burnt crispy or blackened, and
                      do you have a cute girlfriend and/or wife?  BTW, the
                      later AC conditioner suggestion is likely the correct
                      one.  Perhaps even running power through a UPS would be
              \_ peak or RMS?
                 \_ I measured it with my voltmeter, so I guess its peak?
                    how do I measure the RMS? 150 peak is still too high right?
                    \_ 150V peak * .707 = ~110V AC RMS
        \_ given the comment about PG&E, I think you are looking for
           AC power or "line" conditioners, not voltage regulators.
           \_ I think they are the same thing. Most voltage regulators I find
              are also called conditioners.
              \_ ok, sorry, my old school brain thinks voltage regulators
                 are just for pulling down a DC voltage a little off of
                 a battery or charging circuit.

3/28    So I'm really confused about the DC to DC, car-to-laptop power adapter.
        How come most of them are "inverter" types, where you convert from
        DC to AC, and then AC to DC? Isn't that inefficient?
        \_ Using a resistor or transistor to do DC->DC also gives power loss.
           -not an EE.
        \_ It's easier to step up/down the voltage if the current is in the

9/11    Is it practical to have, say, a large portion of CA or AZ running
        on solar power? My coworker runs his entire household via solar
        and it got me to wondering what would happen if everyone did this.
        Obviously industrial plants need more power, but could we do away
        with a lot of our polluting plants if everyone went solar? If so,
        then why don't we? What are the technological obstacles, if any?
