A couple years back, I bought eight huge powerbanks and made myself a 4s4p, 0.4 kWh lithium ion battery for use in my car, to power the fridge and chargers and stuff overnight when sleeping in it. It'll keep my Switch powered on through a good length of blackout, so I don't need to worry catte e: the charger for it is made from this aliexpress "1200W" (which doesn't actually do 1200W under reasonable conditions) constant current/voltage boost converter with a low voltage lockout setting so it doesn't drain the car battery if the ignition's on.

I just got myself a huge power bank lithium battery with a plug socket on the side and a bunch of USB ports on it. Figure if it comes down to massive power cuts that'll get me through a night. That or I'm going to live in my office and hope it's considered critical infrastructure.

Guavanaut posted:You can also make a DAB transmitter to set clock radios out of common parts now though if you're in Ireland or Finland. You're gonna need that in more places in Ireland or Finland, just because those countries on the map earlier are shown as DAB countries, doesn't mean its particularly widespread in all of them. In Sweden for instance it's only around Stockholm IIRC. DAB radio has had a lot of problems. It's worst problem is that because it's high frequency it has lower range than FM. http://digitalradioinsider.blogspot.com/2020/12/the-final-countdown-future-of-dab-radio.html Norweigan experience with DAB and FM shutdown has also not been great. I think the UK might be the place with highest DAB penetration in europe.

In all seriousness, what's the best way to be prepared for blackouts, short or long term? I got an invite from Octopus to take part in their energy usage reduction trial and with everything that's in the news about this, it feels like it's going to be an inevitability in some fashion. I don't wanna be some doomsday prepper or anything, but basics like light, heating and food storage are things I've always taken for granted. Like, how long can a freezer go without power before everything inside thaws; should I stock up on candles or is that crazy privative etc?

If you wanna be more prepared, pack a load of ice blocks in there to provide more a thermal buffer before everything melts. Better than that- overthrow the government and appoint one that's going to build more national infrastructure to prevent this neoliberal disgrace from continuing

Yeah the freezer will go after a couple of days but can still function as a fridge for a bit longer if there's a decent amount of stuff in it. Mine broke a couple of weeks ago and I managed to keep my meat and fish alive for a good few days. If you have a metal sink you can move food in there and cover it with a wet towel to add a bit more time as well *Disclaimer: I live in a basement so it's always naturally on the cold side

I asked a couple of tech nerds about lithium power stations, and they said it would probably be safer to get a leisure battery and inverter for the same price than to trust cheap Chinese imported lithium bombs. I'm still undecided what to get, and still haven't ruled them out, but I had the same warnings from two people I trust, so needed to share. Solidarity to those who need electric transport to get out and do stuff. My wheelchair only has finite trips into town on one charge, and takes ages to fully charge. So yeah... lol... interesting times and all that In other news: https://twitter.com/mikeysmith/status/1587791045781225478

Drinkslinger posted:Back in May, someone round the corner from me burned their house down by burning timber in their living room to save on fuel bills. About a year ago, the people in the flat below mine got a bit desperate because they had no money to run the heating so they found some wooden pallets in the street, smashed them up and tried to burn them in the fireplace. They didn't know the chimney in the building had been blocked off years ago, so the entire building filled with smoke and the fire brigade got called out. Could have been a lot worse though. Gonna see a lot more of this kind of thing over the next few months I think.

If you're really paranoid you can also get a small solar panel to top up the power bank, like 100W should probably be enough to let you charge your laptops and phones and what not, even in winter if there's some sun at least.

Kerosene lamps are probably a good idea, mantle lamps are even better. Plenty of heat and light. I bought a 2nd hand gas grill so I could potentially cook food without power.

Guavanaut posted:What the hell was the point of keeping the long wave radio up and also bringing in all the digital radio if everything is going to fall back to analog FM in an emergency? Analogue radio uses up a bigger chunk of the spectrum than digital so the government would like to phase it out and sell it off like it did analogue TV. Analogue radios are also easy to make yourself and you can make a really crap one without even a power supply (other than the signal itself) but who would think a first world country would need to worry about that?

if you keep the freezer *closed* it will last a long time. They are pretty well insulated and it takes a lot of energy to melt all that frozen poo poo. Ideally don't open it at all for days in an extended power outage.

has anyone got a ballpark for how much these DIY power banks cost? seems like a cure is worse than the disease type situation rn ie. if it would cost me more to put together than it would to just re-buy the contents of my freezer ...unless we're seriously expecting there to be multiple multi-day outages in which case lol

Those compact butane camping stoves can boil water reasonably safely indoors. None of the above are great for indoor air quality though. Get a good coat and some cardigans.

Long underwear really helps, because it can trap warmer air right next to your skin. Even the cheap cotton long johns are fine around the house. That and a warm hat. Those were my go-tos when I lived for a long time in a miserable house with no insulation and lots of black mold, and expensive oil heat.

It's cool and rad that discussion in the UKMT has boiled down to how to retain body heat and sourcing backup power systems. Can't wait until 2023 when we're comparing notes on how to hammer nails into a cricket bat and which roving gang of raiders is best to pay tribute to.
