108V burns up electric motors...And holding the voltage up and allowing the frequency to sag will burn up a lot more stuff besides motors.

Most certainly. 138V does the same thing, although more spectacularly. :-)

(Years ago, I got a BSEE, with a concentration Power Engineering. Unlike AlGore and some other Enviro-nuts, I occasionally can comment on this stuff in an intelligent manner. I actually started using the degree in my current job, which thrilled my Dad to no end.)

Great to meet another EE here on FR.

I’ve got a BS Eng in EE too. We should collect up a bunch of FR engineers and start writing educational pieces for non-technical people to read and ponder as we get more and more of this nonsensical “green power” hype pushed down on us. I foresee a hugely expensive tangent/dead end coming down the road here...

We should start with an explanation of the three laws of thermo, and in particular, law #2, explaining how all conversions come with with an inefficiency/loss. I have the hardest time getting it across to some people that you cannot convert/store energy without an attending loss; eg, solar into heat, or air pressure, or pumping water uphill, etc - all come with a cost on the way into storage, and another cost on the way out of storage back into electricity.

The people who do follow my explanation often come away with a much more skeptical eye/ear for all this fantastic “green energy” hyperventilation.
