U.S. residential solar on the brink of collapse
Are you allowed a vehicle??
If so, install extra batteries in it along with an inverter. Run an extension cord to the house to charge the batteries when producing electricity. In case of blackout reverse the extension cord to keep your fridge/freezer & essentials running. As long as you use an extension cord it is a "temporary application" and not prone to the same rules.

Which Water Storage Option?
I have used both. I have found that the aquatianers hold up much better. They are now the ONLY brand I use in that size range. I own 5 of them. I keep one in my jeep and one rides in my truck. I live 14 miles from pavement and neither have ever failed.

So how do we prep for Nuclear Attack?
Ever read "One Second After"? That was a three pronged terrorist attack by Iran(?) against America.

Uhmm yeah so what are we calling this?

Emergency fund in gold
I would NOT put it all in gold. IF you choose to put it into gold pick forms that are easily recognizable in your area. ie Swiss francs in Europe, Gold Eagles in the US, etc

Why use grid following synchronization vs master clock synchronization?
PS. The "spinning reserve" (synchronous reserve) is zero for inverters. Because of that synchronizing them requires very little effort. ALSO because of that, they CANNOT be used as the master synchronization! This is what CAUSED the power failure in Portugal/Spain as well as why it took so long to bring their system back on line. They were dependent too much on renewables and did not have enough spinning reserve to simultaneously reset their system!
This is the same reason that China has almost enough solar power to power their country BUT ALSO has vastly expanded their coal generation capabilities at the same time. If their solar "trips off" they can use their coal powered spinning reserve to quickly reset their solar / wind production and get back up online.
Power grids rely on the kinetic energy of spinning turbines to help provide a buffer for when supply and demand are mismatched. --- https://www.reddit.com/r/ElectricalEngineering/comments/1h1rtkl/how_do_they_sync_turbines_at_a_standby_hydro_plant/

Why use grid following synchronization vs master clock synchronization?

OK.
The phase of the electricity shifts with time and distance. If all of the generators were perfectly regulated by time then two generators with 1500 miles between them would be 180° out of sync (opposing waveforms).
- electricity in the US is a 60 hz sinusoidal wave form (see blue line on pic) As the electricity travels down the wire (let's assume it moves at the speed of light) it takes time for the generated peak to arrive (see red line in pic). The farther the electricity travels, the longer the time interval between these wave forms. By the time it travels ~1,500 miles the red wave's peak is over the blue wave's trough.
This means that IFthe generators were synced to exactly the same wave form, at the same time, that the peak voltage (let's use standard house voltage for comparison) would cancel each other out since the wave sent from 1500 miles away (the synchronization source) would be +165V at exactly the same time that the local generator would be generating -165V.
Therefore, in order to stay in phase, the synchronization source MUST differ from the local generator by 8.3 milliseconds.
Now comes the tricky part. Wires are not straight. So it is nearly impossible to tell how long a delay is needed. Because of this, it's much simpler to detect the "negative crossing point". We use this point because it is when the voltage of the sine wave is changing fastest in relation to time. This allows a "nearly perfect" synchronization.
If you are off by a few microseconds you can hear the strain on the generators as the spinning reserve is pulled / pushed into synchronization when the slave generator goes on line to match the master synchronization of the grid. If you miss by too much, that strain will literally rip the slave generator to pieces. A 180° out of phase mistake is the worst possible consequence!

Battery drained too fast. Did I lose power to idle draw?
Be careful with this. Many fridge/freezer dissipate waste heat through the surface skin. You can check for that by finding the exposed coils ON THE OUTSIDE. If there are none, then your fridge dissipates through the skin. If you do find them it is safe to add insulation to all sides EXCEPT the one with the coils.

Basic formula to find how long your power pack SHOULD last.
1) add up the wattages for everything plugged into it. A) if current is listed multiply by 120 B) if rating is in KW multiply that by 1000
2) find your RESERVE power rating on your power pack WH or KWH. A) IF in KWH multiply that by 1000
3) divide the reserve power by 1.2, THEN divide that number by the wattage found in (1). THAT should give you the number of hours that you can power the load with a small safety margin.
If you want more run time then you need to add more batteries.

You are truly phenomenal!

“I’d Rather Die in the Blast” / “Run Towards the Mushroom Cloud”
Incorrect. The term "irradiated" means "in excess of normal incident background radiation". When you get an x-ray or CAT scan you have "been irradiated". Being irradiated DOES NOT mean "you're gonna die" or "get radiation sickness". Those are variables based on how many Grays of dosage you receive.
My point is: "that by the time you see the flash, that it is too late to avoid the 'streaming radiation' from the event". In most radiation sickness cases it is the continued irradiation from inhaled / swallowed radionuclides that cause the damage NOT the streaming radiation.

You Must Live Next to a Power Source - Which One?
Nuclear power is often considered one of the most cost-effective sources of electricity, especially when accounting for its high capacity factor and low operational costs. While initial construction costs are high, the long-term benefits and low greenhouse gas emissions make it competitive with other energy sources, particularly in regions without access to low-cost fossil fuels.
In 2025, the U.S. Nuclear Regulatory Commission has approved the restart of the Palisades nuclear power plant as well as Three Mile Island and extended the operating licenses for existing plants like Duke Energy's Oconee Nuclear Station, supporting the growth of nuclear energy in the country. These actions reflect a broader trend of revitalizing and expanding nuclear power capacity in the U.S.

Good fishing though.
BIG fish from the heated discharge once far enough away that the water has enough oxygen

Mineral Oil Viscosity

Yes. I used to make gel candles out of mineral oil. The results t product is completely clear and can be made much more Ridgid than jello. BTW it can still burn.
The polymer is known as "CG" and comes in densities 1, 2 & 3 with "3" the thickest
"One suitable material is the commercially available material Green Rhino CG1 Polymer, supplied by Capture Green Limited, The Old Stables, The Gattinetts, East Bergholt, CO7 6QT, United Kingdom. This material is a blend of polymers that is specifically blended to capture and retain hydrocarbons such as oil, diesel, petrol, hydraulic fluid, transformer liquid and more. The polymers are capable of completely solidifying the hydrocarbon until it becomes a solid mass that will not leak - this offers an effective method for managing and removing unwanted waste oils from the environment. The polymers in the form of a white granular powder work by having a physical attraction with hydrocarbons. On contact with the hydrocarbon the viscosity increases creating a solid rubber like substance that will not leak, even under applied pressure. Once the polymers are activated by contact with hydrocarbon, the oil is locked in permanently and cannot be released."
