+We dedicate this Module to the Mother &
Father of Integral Permaculture: Dana Meadows & Howard Odum, two original
pioneers who helped humanity make great strides in understanding systemic
thinking, in all four quadrants.
How do we Design good EcoTechnologies? Part 1*
Technology is the application of science, so a good basic knowledge of science is essential if we are to design technologies of any kind.
*And everything that transforms energy or matter from one form to another is a technology, so science and technology really are basic for life, and certainly
for designers. *
In this first part of two we explore the relevance of space elevators to permaculture, then delve into the science of heat, flows, optics & materials in
order to understand how to best design ovens, solar devices, heating & cooling technologies - with lots of examples

"Love (erôs) is the oldest
of all the gods."
images from "Big History" TED Talk by David Christian
"Firstly, ancient Khaos’s stern Ananke (Inevitability), and Khronos (Time), who bred within his boundless coils Aither (Light) and two-sexed, two-faced, glorious Eros [Phanes], ever-born Nyx’s (Night’s) father, whom latter men call Phanes, for he first was manifested."
Within the first second of the big bang,
the Four Fundamental Forces of Nature appeared ...
The primordial Eros is usually named
Phanes,
regarded by some as the Fifth Force
... which doesn't appear in this "Big History" picture.

6 Ways to Die■too hot (see cooling and shelter)

■thirst (see water supply and water purification)
■hunger (see food and agriculture)

Nothing happens without heat flow. There are no exceptions.
Heat – What is it?
Heat flows from a hot body to a cold
one ...
... as particles vibrate & transmit kinetic energy to
their neighbours
until they are all at equal temperature
Everything happens because heat is flowing from a hot place to a cold place.
Nothing happens without heat flow. There are no exceptions.

Heat can also be transmitted
with no contact (& in a vacuum)
by RADIATION

The pituitary gland is called the master gland because it directs the actions of the endocrine glands that are below it.
Clinically, each endocrine organ has a very specific
nutrient that makes it work. Unbelievably, the specific nutrient for the pineal
gland is light. In order to function normally,
the pineal needs to be exposed to the entire
spectrum of light.
It is interesting to note that the pineal gland is the remnant of a third eye that appears early in the developing fetus. Mystics have been saying for centuries that the third eye is responsible for our inner sight (insight), and directly connects us to our spiritual self.
