Self-Sufficient Living

by

What does it mean to be self-sufficient?  

For some the simple answer is taking care of ones self.  For others, it is more extreme.  They want to live without the help of others.   The purpose of this section is as a resource for those who desire to live in between these two ideas.

I have often thought that I would like to turn back time and find some acreage where I could grow my own food.  Don’t know that I would raise cows, chickens or pigs.  Just having a garden with fresh organic vegetables could be wonderful.

It was just a few generations ago that our grandmothers or great-grandmothers made quilts to keep warm, sewed clothes, made jams & jellies, made soap and made those homemade berry pies.
 

Using SuperCapacitors for Energy Storage

by

Supercapacitors (also known as ultracapacitors) are DC energy sources and must be interfaced to the electric grid with a static power conditioner, providing 60-Hz output. A supercapacitor provides power during short duration interruptions and voltage sags. By combining a supercapacitor with a battery-based uninterruptible power supply system, the life of the batteries can be extended. The batteries provide power only during the longer interruptions, reducing the cycling duty on the battery. Small supercapacitors are commercially available to extend battery life in electronic equipment, but large supercapacitors are still in development, but may soon become a viable component of the energy storage field.

Hydrogen Fuel Cells used as a Energy Storage Option

by

A fuel cell is similar to a battery in that an electro-chemical reaction is used to create electric current. The charge carriers can be released through an external circuit via wire connections to anode and cathode plates of the battery or the fuel cell. The major difference between fuel cells and batteries is that batteries carry a limited supply of fuel internally as an electrolytic solution and solid materials (such as the lead acid battery that contains sulfuric acid and lead plates) or as solid dry reactants such as zinc carbon powders found in a flashlight battery. Fuel cells have similar reactions; however, the reactants are gases (hydrogen and oxygen) that are combined in a catalytic process. Since the gas reactants can be fed into the fuel cell and constantly replenished, the unit will never run down like a battery.

The fuel (hydrogen) enters the fuel cell, and this fuel is mixed with air, which causes the fuel to be oxidized. As the hydrogen enters the fuel cell, it is broken down into protons and electrons. In the case of proton exchange membrane fuel cells (PEMFC) and phosphoric acid fuel cells (PAFC), positively charged ions move through the electrolyte across a voltage to produce electric power. The protons and electrons are then recombined with oxygen to make water, and as this water is removed, more protons are pulled through the electrolyte to continue driving the reaction and resulting in further power production. In the case of solid oxide fuel cells (SOFC), it is not protons that move through the electrolyte, but oxygen radicals. In molten carbonate fuel cells (MCFC) carbon dioxide is required to combine with the oxygen and electrons to form carbonate ions, which are transmitted through the electrolyte.
