I thought it might be a good idea to get a discussion going about ideas and solutions for emergency power generation/storage in case of power outages, EMP Protection and Heating/Cooling as well as handy devices. I did some research over the years on those topics and thought it might be a good idea to share some of my results, as well as my personal setup for power generation/storage, EMP protection and Heating/Cooling as well as handy devices.
Here are a couple of basic rules to consider first:
- In general, if you want to power anything that is even slightly power hungry in an acute emergency, it is almost impossible to do so for longer periods of time especially for small emergency setups. Those devices can be powered just for small amounts of time (at most, for hours or a couple of days) even with big or huge energy reserves at your disposal (such as a big fuel/gas tank). Power hungry appliances/devices devour lots of energy very fast, and you can't expect them to run normally in an emergency "off grid" situation.
- In general, the most power hungry appliances are those that generate/create lots of heat (such as a welder) or moderate heat (such as a heater), or reversely, cold (such as Refrigerator), followed by devices/appliances that need to generate lots of mechanical force to operate (such as a washing machine, power drill, buzz saw etc.) followed by old-fashioned light bulbs.
- If you thought you could power such high-power devices via solar energy, wind energy etc. "Off Grid" in any reliably/normal and/or long-term way, just forget it. It doesn't work. Generally speaking, you need an energy source that has a high-energy density such as fossil fuels (Diesel, Petrol, LPG-Gas etc) to power such in any sensible devices, but even then, the fuel will be consumed pretty quickly.
- So in an emergency, it is a good idea to rethink what you actually really need to power (most especially in terms of those high-power devices). And if you really have to power any of those high-power devices, you need to know that you should be careful with your energy reserves. For example: let's say you need heat to cook and/or to generate warmth; think it through and look for a solution that is the most energy saving and long-term reliable solution you can think of under specific circumstances. Here are some ideas, especially in terms of high-power consumption.
There is a lot more to say, and I will try to do so in the coming days/weeks on follow-up posts. For example, I'll describe how you can set up a relatively low-cost emergency power system that should be more or less EMP proof, so that you can power basic electric stuff and even some more power intensive stuff for short periods of time, from time to time. I'll also present some tools, electric stuff etc. I bought over the years that could come in quite handy in an emergency.

Here are some ideas, especially in terms of high-power consumption.
- For Cooking: If you can, get yourself a gas oven with as many propane gas tanks in storage as possible (see later points: Propane Gas Tanks are pretty handy for emergencies!). I have one from a company called Kaiser. And more importantly; a gas powered stove! (There are also solutions that include a gas oven as well as a gas stove together in one package). For example: If you have a gas powered stove and a normal sizes 11kg Propane Tank (such as this one), you can easily cook with it and a regular pan/pot for many months, several times a day! And if you have several tanks in storage you could easily cook for years! One such tank can hold very long for just cooking via a pan/pot (and smartly prepared food such as thinly sliced up meat (which is done quicker= less energy consumed)). If you want to get fancy in an emergency and actually use the gas oven instead of the stove you can do that as well, just know that it eats quite a lot more gas fuel, but still can get you through for quite a long time with no need for any outside power. Our Gas-Oven can be easily operated every second day or so for cooking a large junk of meat for quite a number of months.
For Cooking: you can of course also do it via wood and fire if you can. - For Heating: If you have one or can install/get one, a wood stove is of course one of the best solutions
- [Edit (28.08.2022): See here and here for a possible good/easy wood stove solution.]
- For Heating: You can use a 11kg Propane Gas Tank pretty effectively for heating, just be aware that heating consumes a lot of fuel/energy. So be smart about it: If you have to heat a room; think of the smallest and/or best isolated room in your house and just heat that room whenever needed with a device like this one and a Propane Gas Tank
- For Heating: If you want to get really smart/nerdy about it, you could for example install the Propane Gas Oven in said small room and kill two birds with one stone: You cook and heat the room at the same time!
- For Heating/Cooking: If you have a Diesel and or Petrol Tank you can use that to your advantage as a fuel. Just be aware that especially heating consumes a lot of fuel/energy.
- For Heating/Power: Cars with fuel Tanks can produce quite a good amount of heat/energy
- For Heating/Power/Travel: If you can, get yourself a car that can run on petrol as well as on LPG, or alternatively install a LPG-system into your petrol engine powered car relatively cheaply. I'm not so sure yet but I guess you could also use your Propane Gas to power the car.
- For Power: A Propane Gas Tank can be used quite well in combination with an energy storage such as a good battery/energy generator. See later points.
- For Power: If you have the means and space to do so, an old Diesel generator might be an option, since apparently (I'm not sure), they can eat not just Diesel, but also things like salad oils etc.
- For Power: if you can and have the means you could also consider a so-called Multifuel Generator that "can be operated with diesel, heating oil, straight vegetable oil (rapeseed oil, canola oil, sunflower oil, coconut oil, copra oil, corn oil, soy bean oil, palm oil, jatropha oil, ...), cleaned waste vegetable oil or pyrolysis oil." When I looked into it a while ago, I found the following one quite interesting: ATG MULTIFUEL 3SP Power Generator 3 kW | ATG and this one Multifuel Biofuel Power Generator Diesel Biodiesel vegetable oil waste oil. The Multifuel idea for emergencies was something I researched a bit more extensively in the past, since there seem to be smaller type of devices that can do that you could actually carry. See following posts/points.
There is a lot more to say, and I will try to do so in the coming days/weeks on follow-up posts. For example, I'll describe how you can set up a relatively low-cost emergency power system that should be more or less EMP proof, so that you can power basic electric stuff and even some more power intensive stuff for short periods of time, from time to time.
