Self-Sufficient Living

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.

Solar Air Conditioning
From:  tculhane

This video starts with a visual montage of the sheer number of air conditioners used on our street in Cairo, Egypt, describing them as energy parasites that actually increase the heat of the surrounding air. It then shows the vacuum tube heat pipe solar absorption cooling air conditioning system installed by solar engineer Les Hamasaki at the Debs Park Audubon Environmental Center in Los Angeles. Les Hamasaki describes the 10-ton solar chiller and we conclude with a note about how solar chillers not only eliminate the need for air conditioners,…

Solar House Lights
From:  wheels773

I turned on all the lights so I could get video of the house at night. About 15 lights on, drawing less power than 2-60 watt incandescent bulbs. My solar system made about 3000 watts of electricity on this hazy day.

Using SuperCapacitors for Energy Storage

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.

The photovoltaic cells were developed at Bell Labs in 1950 primarily initially for space applications. The Hubbell telescope utilizes solar panels for its energy requirements.
