Choosing and Maintaining a Power Outage Generator:

Multifuel (hybrid) Generators are capable of running on Gasoline, Kerosene, LPG/CNG/Bio-Gas fuels. Fossil fuel [only] generators will not be practical when fossil fuel resources become scarce. A generator (3000 watts or more) with AC (Inverter) outlets for critical electrical appliances can help during a power outage, especially during the summer to help keep refrigerators and freezers running for extended periods of time. SOLAR GENERATORS: Diversification is a trait of a true prepper who doesn't rely on a single type of resources. That's why even a hybrid [fuel] generator may not be the only power solution for a prepper. That's when a "Solar Generator" can be used to fill the gap. This type of generator runs appliances using only rechargeable [car size] batteries and an inverter to convert DC power to AC power for appliances. An electric source (usually solar panels) recharges the batteries but it can be recharges from an electrical outlet, wind turbine or water turbine. There are many commercial models on the market but can also be DIY with the correct knowledge. Use this link for further research on Solar Generators. It is recommended that the selected Solar Generator be able to daisy-chain to exterior batteries to extend the duration of the power (not, usually, the power output/wattage). In other words, additional connected batteries will increase how long power lasts (1 hour to 2 hours) but will not increase the wattage of the output (1200 (+/-) watts to 1500 (+/-) watts). Additionally, daisy-chaining exterior batteries will be cheaper than daisy-chaining multiple Solar Generators. Calculate the appropriate sized generator, necessary to run critical AC electrical applicances and medical equipment, by adding together your appliance wattage (amps X volts = watts) requirements. SAMPLE: Refrigerator = 800 watts (6.7 amps X 120 volts) Microwave = 700 watts (5.8 amps X 120 volts) ------------------------- TOTAL = 1500 Watts (a 2000 Watts generator) Additionally, understand that some appliances require a surge of power before they reach their continuous power usage. For example; a refrigerator needs to run on a surge of electric for its compressor before it reaches its designated temperature setting. It may require 800 watts of surge power until it reaches its designated temperature setting and then drop down to about 600 watts. So, for this particular appliance, a 1000 watt generator will power the refrigerator. It's alway best to acquire a generator that produces more power than you think you may need. Keep this in mind if using a power inverter as the same rule applies. The more devices plugged in to the generator, the less time it will run. Know its fuel/battery capacity and how long it will run on a full tank/charge. Keep enough fuel on hand to fill it several times (possibly for as long as a week). Keep in mind that a Solar Generator can be recharged by a fuel generator so both types can be used in an emergency to extend your power capability, and save fuel, during an outage. When the Solar Generator dies, start up the Fuel Generator to run appliances and recharge the Solar Generator. Then switch back to the Solar Generator to save your fuel supplies. Test run the generator at least every 6 months with at least one appliance (refrigerator, portable heater, etc.) attached as a power-outage simulation. Refer to our Post on Generators. Ground the Generator: Quick Guide to Grounding Portable Power Generators When the generator has completed its mission and it's unused until the next mission, turn off the generator's fuel switch, and run it until it dies (runs out of fuel in the line) to remove fuel from the fuel line to reduce the chance of generator fuel line clogging, freezing or damage. Then turn off the power switch. Use Fuel Stabilizer (STA-BIL, etc.) in the fuel storage container (gas can), appropriate to the type of fuel being used, to further reduce the chance of generator fuel line clogging or damage. It's best to use pure fuel (no Ethanol). Change generator oil at least once a year; more if used frequently.

🚀🧪💌 - For the fic ask (was gonna send these last night and passed out instead a;ldkj;flkf)

Hfjdjdjxhjss s l e e p

🚀- Do you like to outline your fic first or create as you go?

Little bit of both! The first wall of text just happened in my phone notepad while I was 100% supposed to be putting books away, but when I got back to my pc I put together an outline cus frankly the last fic I got any distance into fell apart cus I wrote myself into a corner and I don't want that to happen again. That being said, the oneshot was a 3 hour manic episode that just sorta poofed into my head fully formed, so ¯\_(ツ)_/¯ bit of both! I think I prefer an outline though, for the sake of my sanity lol

🧪- do you research for your fics?

Er. Yes and no. Did I spend an ungodly amount of time pouring through literal actual medical journals that I have access to as a librarian to make sure I knew what the fuck i was talking about? Yes. Did i throw that information out the window later because it was inconvenient and fuck it they're both deities anyway? Also yes fjdjdksk i've gone over entirely too much in game stuff to make sure I'm not making up toooo too much, but I also have a tendency to throw accuracy into the wind for the sake of either simplicity or 'this is a bit handwavey but Vibes Harder'

💌- is there a favorite trope you like to write?

I was gonna say this is a hard one to answer because I just haven't written that much But-

There's a very Whumpy lean to everything I've written, finished or unfinished, and it frequently takes a sort of long term inevitability bend at some point. In the One fic I've posted (and abandoned since) Bakugo was going to recover, eventually, but he was going to have to figure out either how to be a hero without his eyes or ears, or find another purpose to strive towards. There's a pile of AAA in my notes about Fi, and how the master sword slowly rotting away over tens of thousands of years must have felt, when she hadn't been able to speak since the very first hero, when she'd been imprisoned inside this rusting breaking frigid metal. The oneshot is essentially a trauma flashback, the whole thing; and the big one is a fistful of excuses and headcanons for why the statues work the way they do, why the traveler can increase their stamina by making offerings to them, what effects having a massive part of yourself sealed away might have, where the energy to wield elements even comes from etc all balled up into a very specific kind of whump and my utter bullshit nonsense shenanigans to heal said specific whump fjdjdkdkk it's a whole mess

Tldr I like to hurt the characters I love, apparently :kermit scream:

Thank you for asking!! This is fun, i have more to say than I thought I would fjfjdk

Lightning Arresters Uses

Lightning Arresters are widely used all over the world in different industries. Here are the top uses of Lightning Arresters -When a traveling wave reaches the arrestor, its sparks over at a certain prefixed voltage. The arrestor provides a conducting path to the waves of relatively low impedance between the line and the ground.

The surge impedance of the line restricts the amplitude of the current flowing to the ground.

The lightning arrester provides a path of low impedance only when the traveling surge reaches the surge diverter, neither before it nor after it.

Instead of burning fossil fuels to reach the temperatures needed to smelt steel and cook cement, scientists in Switzerland want to use heat from the sun. The proof-of-concept study uses synthetic quartz to trap solar energy at temperatures over 1,000°C (1,832°F), demonstrating the method’s potential role in providing clean energy for carbon-intensive industries. A paper on the research was published on May 15 in the journal Device.[...]

Glass, steel, cement, and ceramics are at the very heart of modern civilization, essential for building everything from car engines to skyscrapers. However, manufacturing these materials demands temperatures over 1,000°C and relies heavily on burning fossil fuels for heat. These industries account for about 25% of global energy consumption. Researchers have explored a clean-energy alternative using solar receivers, which concentrate and build heat with thousands of sun-tracking mirrors. However, this technology has difficulties transferring solar energy efficiently above 1,000°C.

To boost the efficiency of solar receivers, Casati turned to semitransparent materials such as quartz, which can trap sunlight—a phenomenon called the thermal-trap effect. The team crafted a thermal-trapping device by attaching a synthetic quartz rod to an opaque silicon disk as an energy absorber. When they exposed the device to an energy flux equivalent to the light coming from 136 suns, the absorber plate reached 1,050°C (1,922°F), whereas the other end of the quartz rod remained at 600°C (1,112°F).

“Previous research has only managed to demonstrate the thermal-trap effect up to 170°C (338°F),” says Casati. “Our research showed that solar thermal trapping works not just at low temperatures, but well above 1,000°C. This is crucial to show its potential for real-world industrial applications.”

Using a heat transfer model, the team also simulated the quartz’s thermal-trapping efficiency under different conditions. The model showed that thermal trapping achieves the target temperature at lower concentrations with the same performance, or at higher thermal efficiency for equal concentration. For example, a state-of-the-art (unshielded) receiver has an efficiency of 40% at 1,200°C, with a concentration of 500 suns. The receiver shielded with 300 mm of quartz achieves 70% efficiency at the same temperature and concentration. The unshielded receiver requires at least 1,000 suns of concentration for comparable performance.

It’s not over yet! May 11/12 aurora watch continues

It was a good night for aurora watchers all over Europe on the evening of May 10th/11th, 2024. Here's a great brief timelapse video sequence from Berkshire in the UK (via @Rainmaker1973 over at the Bye Bye Birdie place).

Among numerous other displays, this particular broad, pink "banner" structure was widely observed across the UK and Ireland around midnight local time / 2300 UT. It persisted, twisting and morphing into a variety of new shapes, for something like half an hour. The night's display as a whole was definitely one for the record books.

The early projections at the NOAA site suggest that the power of the incoming geomagnetic storm will be significantly less on Sunday, May 12th. But the night of May 11th still holds possibilities, as for the time being the storm seems to be holding at the relatively high Kp 8 level (on a scale of 0-9).

NOAA space weather forecasters have observed at least seven coronal mass ejections (CMEs) from the sun, with impacts expected to arrive on Earth as early as midday Friday, May 10, and persist through Sunday, May 12, 2024. 

Here are the early graphic projections for the zone of visibility on the evening of May 11 2024. Please note that (a) these are approximations and estimates, not hard and fast indicators of where the solar wind makes planetfall; and (b) as they did last night, they may well improve over the course of the day as newer and better data reaches the predicting devices and personnel.

The European animated projection comes via ITV (UK) weatherman Chris Page.

North American prediction images come via the Space Weather Prediction Center at the NOAA website. Right now (9:30 PM IDT / 2139 UT on May 11th) the NOAA's evening prediction animation for Europe and North America hasn't been generated yet. This still image (updated 1900 IDT) shows where the auroral viewing zone stands right now. The "likelihood of viewing" for Europe seems to have dropped pretty much into the 30-40% range.

That said, though, it's worth noting that the NOAA earlier issued yet another geomagnetic storm watch warning for 12 May, as the Sun apparently popped off both X-class and M-class flares early today; the effects of those are now in transit toward Earth. So we'll see in a day or so what comes of that. Sunspot region 3664, which has been responsible for all this excitement, is plainly not done spitting out flares just yet.

As regards tonight's predictions, it also remains to be seen whether what we get will be better... considering that last night's displays far outpaced everybody's expectations. I for one am quite willing to be surprised. 🙏

It's also worth noting here that so far today, the Kp index illustrated at the Space Weather Prediction Center's experimental aurora dashboard page—an indicator of the current strength of the geomagnetic storm—hasn't dropped off very much from last night's highs. It'll be interesting to see how this behaves as the day goes on. (ETA 2: image updated 11/05/2024, 2140 IDT)
