What if in the near future with supply and demand issues , petrol becomes not practical or un-affordable . "WORST CASE SCENARIO" , what kind of wheeled vehicle runs on nothing..? I've been pricing "MULES" , yes , mules..! It is possible that the quest for fuel may be as much a problem as food..!
Maybe I'm looking too deep here , but , something I can see as a potential problem. Feet will get me from point A to point B. To share the "work-load",
I may need some other means of muscle. Fuel is something to look at..!
In five years or whenever , will I be able to get fuel..?
That also bring to mind , (HOW USEFUL" will my generator be..?
Wind , water , decomposition , sun , other back-up sources of power..?
Just a thought..!
