Home Defense Chapter 2: Keeping Your Survival Appliances Mobile

 

Most homes that run partially off solar hard mount solar panels to roofs to secure against wind and theft. The best advice I would offer is for the owner to have the knowledge how their panels are mounted and how they would go about removing them if needed. They would need to come down and hidden in a secured area. Use a technique that I call “mobile redundancy”.

How Do Inuit Survive Without Fresh Vegetables and Vitamin C?

The Inuit, also known as Eskimos, have lived on the frozen tundra for thousands of years consuming meat alone. There were no gardens, fruit trees, berry patches, or a food supply chain in the arctic back in the 1600s. Yet mariners on ships from Europe would suffer scurvy, the lack of vitamin C, if they were out to sea for months. So are Inuit’s biology differ from everyone else? The short answer is no.

Manually Balancing Ultracapacitors

In my post “Resisters and Diode To Balance” is the hardwire attempt to “auto” balance a set of ultracapacitors (CAPs). In reality, I don’t even need an electronic balancer, just common sense. Each CAP has its own internal capacitance. Due to age, loading, heat stress, etc. each cell varies. When I rack a set of say, seven together, the CAP with the lowest capacitance would be subjected to higher voltages by the mating CAPs in the set. The rated over voltage for a CAP can also change with age and stress. I always over size my CAPs to the total applied voltage. If each CAP is rated at say 2.7 volts, and I will need a starting storage voltage at say 18 volts, then I will use (8) CAPs that has the total capacitance of about 22 volts. If my CAPs are aged, I may use (9), totaling 24 volts. This “2.7” volts is theoretical when the CAP were newly manufactured, hence I mix and match actual capacitance.
