Researched power, generation, comms, water, food and survival systems for people who intend to be self-reliant. Built on manufacturer specs, electrical math, and what actual owners report after years of use — not marketing copy. Honest engineering, sources shown.
Every recommendation is researched against specs and real owner reports. No sponsor owns the verdict.
Affiliate lists ranked by ad budget. "Reviews" written from a warehouse by someone who has never watched a battery bank sag at 3am. That's the noise. This is the signal. Every recommendation here is checked against manufacturer specifications, the actual electrical math, and what long-term owners report in forums and build threads — then handed to you as a straight answer, so you don't fund the mistakes with your own money.
Pick your platform — van, RV, power station, or cabin. Load in real appliances. Get your battery bank, solar array, controller and inverter, with every formula shown, hard warnings when your voltage architecture will cost you, and a roof-space check most tools skip. No ads, no signup, no email.

Four pillars, all live, all built to the same standard: research it properly, show the math, name the weaknesses. Power, generation, comms and survival — plus deep guides on water, food storage and safety.
Sizing, batteries, panels, inverters, wiring. The free Sizer plus the gear that survives real draw.
LiveBeyond solar: wind, micro-hydro and DC-DC alternator charging for power when the sun quits.
LiveStarlink, cell boosters, GMRS and LoRa mesh — layered so you're never fully dark.
LiveWater purification, the 30-year pantry, electrical safety and the first-aid kit that matters.
The Long Dark Season is a survival sim built on the same electrical math as the Sizer. Read the forecast, choose what runs, and keep the bank alive from late autumn to spring. Let it hit zero and everything shuts down at 3am.
Most people die in the first two weeks. Salvage carries over — the upgrades are permanent.
Play The Long Dark SeasonFifty-two researched notes on power, water, food storage, comms and safety. Each opens with a specific figure that changes a decision, names the mistake people make, and tells you what it costs in watt-hours.
Read the field notesBut thousands of people living off-grid have collectively solved almost everything — the fix that worked, the gear that quit at year three, the number the spec sheet got wrong. Most of it never gets written down.
Write it down here. Good reports get published with your name on them.
Send a field reportEvery recommendation starts with the engineering: the actual draw, the real derates, the failure modes. Then it gets checked against what owners report after a year or three of use — the forum threads, the build logs, the complaints that never make it into a review. Where something has a known weakness, you'll read about the weakness here. No brand decides what earns a recommendation.
That's the whole edge. A content farm can out-publish me. It can't out-think me — and it won't tell you when the popular pick is the wrong one.
Read the doctrineWhere gear is running in my own build, it's labeled. Build logs and photos land here as the rig comes together.
Power stations, LiFePO₄ batteries, panels, inverters, and off-grid connectivity — narrowed to what earns its weight and price on specs and owner track record. Rig or no rig. Fewer choices, better ones, reasoning shown.
See the gearOne email, zero fluff: the sizing math, the gear that holds up long-term, the failure modes worth knowing, the mistakes to skip. For people who'd rather run their own power than read another top-10 list.
