Self-Sustaining Technologies
A system is self-sustaining (or self-sufficient) if it can maintain itself by independent effort.
Whereas self-sustainability is a quality of one’s independence, survivability applies to the future maintainability of one’s self-sustainability and indeed one’s existence. Many believe that more self-sustainability guarantees a higher degree of survivability. But just as many oppose this, arguing that it is not self-sustainability that is essential for survivability, but on the contrary specialization and thus dependence.
100% Sustainable Homes
Just because you want to live in completely self-sustaining home, doesn’t mean it has to be primitive, as if it were separated from the 21st century! Believe it or not, these homes actually have quite a lot of modern amenities you would find in a typical home.
No matter what climate it is, Earthships can grow their own food and crops year-round. Optionally, you can choose to build a fish pond or chicken coop for a continuous source of eggs and meat.
Even the most arid and bitter climates are no match for an Earthship, which uses one-of-a-kind rain harvesting system to provide a brilliant use of water recycling. First, water collects on the entire roof of the Earthship. This water funnels down into a cistern which pumps it into sicks and showers.
Thanks to the wind turbines, and an entire roof dedicated to solar panels, you’ll never be short of power, just as long as you aren’t being too aggressive with your electricity use.
Self-Sustaining Street Lamp
Most solar panels turn on and turn off automatically by sensing outdoor light using a light source Solar streetlights are designed to work throughout the night. Many can stay lit for more than one night if the sun is not available for a couple of days. Older models included lamps that were not fluorescent or LED. Solar lights installed in windy regions are generally equipped with flat panels to better cope with the winds. Latest designs use wireless technology and fuzzy control theory for battery management. The street lights using this technology can operate as a network with each light having the capability of performing on or off the network.

I find self-sustaining technologies a great advance in society, and I'm glad you wrote a blog page about it. Since technologies were made to make the human life easier it makes only sense to make them sustain themselves, so we don't have worry about maintainance. The self-sustaining street lamps was my favorite, it's such a smart creation, and good for the enviroment too!

Rafael Massoni, I think the same, bu in order to use the self-sustaining street lamps, it's necessary a good quantity of solar light, some countries don't have it, making the lamps difficulty to use.
