Weather, utility power, and condensation

Got the coffee going this morning and my Cyber Power 1500VA was blinking on and off every few minutes with complete breaks of a couple of
seconds accompanying. REC line voltage usually runs 124 during low usage times. This morning is has been blinking with numbers (on the CP
display) of 116 thru 120. Some folks around here have total electric homes. I feel for them as we have storms and things like a motorist plowing
into a utility pole and it knocking out power. I don't like to be in that situation so I provided elect, wood, propane, and finally was able to include
a non-portable Generac.

So, back to our recent discussion about humidity and sweating of building ceilings and all that, I found a calculator and thought I'd play some
games with numbers. First of all I post a definition I found on the www from a forum somewhere:

Question posted was: "What does 100% Relative Humidity really mean.
Answer came back:
"It's based on the capacity of the air to hold water vapor. At 100%, the air has taken up as much water into the air as it can. If the temperature
or pressure changed to reduce this carrying capacity, then the water will condensate back into a liquid."

Neat.

Here are this morning's readings from our local weather station of "The Weather Underground" who post on Intellicast sites:

Temp (F) +10
Dew Pt. +6
Rel. Hum. 85%

So I diddle some www questions, come up with a site with a calculator and plug in some numbers for grins:

We already have today's real world so I changed the temp and dew point to be equal at 10F. Yes the RH went to 100%. Neat

So I decided to go to the tires on one of my tractors which are 75% filled with fluid and sweat where filled on certain days where the rest of the
tire isn't sweating. I plug in a temp BELOW the dew point which is the condition when the liquid cooled over night and is slower at warming up
the next day than the ambient air, or is like the condenser coils on your home refrigerated air conditioner, or like your glass of iced tea sitting on
the table, or like the unprotected tin on your shop's roof or shed:

Temp of tire with liquid 10F
Dew Pt. 12F Calculating RH......
RH 109% and the tire is sweating just like the tin on the roof if uninsulated and the other things mentioned.

Oops....evaporator coil, not condenser...evaporator is inside the dwelling and absorbs heat when the pressure of the refrigerant is reduced. Condenser (outside the dwelling) emits the heat carried by the gas when it is condensed back into a liquid under pressure.

Your comment about all-electric homes being without power brought back a memory from years ago, when the local REA was pushing electric heating. They mentioned that prospective customers were concerned about that, but when power is out, the oil burners and LP furnaces can"t run either. Those with wood stoves, even with an electric fan, can fare a bit better.

That's true if you own a central (which I don't) or like you guys up North, a furnace in the basement. That's where I think you have to just factor a standby generator into the price of having a place to stay.

Yes as Tex just put in. Us guys who know what we are doing. If you plug your oil heater in to your handy dandy generator....you have heat. Ever try to run a home with electric heat? Better have a CAT generator unit parked out front.

Not sure if the problem still exists, but when the high efficiency gas furnaces first came out, people wanted to have a back up generator to power them. They found out the voltage (sine wave) generaterd wasn't clean enough, messed with the electronic brain box.

Not sure if there are better generators or better brain boxes or both.
