Regardless of the device you are talking about, there are always going to be weak points that will lead to the device being discarded. When it comes to power generators, the part that actually produces the electricity may still work, even though the entire unit has been discarded.
If you can’t afford a brand new generator, or are concerned about the cost of fuel, finding a scrapped out generator might be a good start. Depending on the reason for it being discarded, you could modify it to turn solar or wind power into electricity.
From taking steps to get off the grid, to preparing for a major emergency such as we’re seeing in Puerto Rico and California, knowing how to convert a scrapped out generator is a skill that would provide you and your family a warm shelter.
Once you are successful in converting your own generator to harness solar and wind energy sources, there is every chance that you can turn this into a saleable trade and time of need.
