The rubber band engine is cheap and easy to make, and can be adapted easily enough to run on heat from a solar capture device.
This type of engine isn’t the most efficient device, but if you have been looking into power generation systems, then you already know that most systems are inefficient.
To generate a reasonable amount of electricity, the device either has to be very large or made from materials that are very expensive. Add in the cost of batteries and voltage regulators, and it may seem impossible to gain energy independence.
But why wouldn’t give this little fellow a chance and try to make one for your homestead?
It is no secret that anything from EMP blast and natural phenomena to outright sabotage from inside the country can lead to large scale disruptions in the power grid.
You have at least a few electronic devices that you’ll need to operate until you have made a full adjustment to living without electricity. Regardless of whether you need to access data on the memory chip for your smart phone, health monitoring tools, or even a battery powered radio, you should know how to generate electricity using as many methods as possible.
Overall, generating electricity or other sources of power from mud may be a viable option.
If you’re an outdoor enthusiast or just well versed in the fine arts of prepping, I bet you already know about alcohol stoves, either DIY or commercially available ones. The thing is, if you’re looking for the lightest, cheapest and most reliable stove possible, the alcohol stove is the one for you.
There are plenty of companies out there who manufacture and sell alcohol stoves, but the good news is that you can build your own for next to nothing while using basic tools and skills.
Over the years, I’ve given a lot of thought to just how much I should try to avoid modern electronic devices when it comes to prepping. I have also sought, wherever possible, to end or reduce reliance on electricity and anything else that requires a major social or commercial effort.
There are some devices that I feel cannot be done away with, at least in the final stages of a major social collapse and during the first few years after.
In this case, I refer to Arduino computer controllers. These small devices are very easy to customize and can be used to increase your odds of survival.
