Is there a spontaneous Technology?

let's look on the meaning of the word spontaneous- (from Oxford dictionary)-

adjective

performed or occurring as a result of a sudden impulse or inclination and without premeditation or external stimulus.

and now the meaning of  technology - 

noun (plural technologies)

[mass noun]

the application of scientific knowledge for practical purposes, especially in industry.

From those definitions I conclud that the word "spontaneous" is not the right word, becuse to "do" technology we need to plan, to use some kowledge and spontaneous is work from the instinct.

Therefore I call those technolgy- Improvised technolgy.

How can we identify improvised technolgy?

1. Specific need (utilities- Utilitas)

2. Imported material or object-Due a lack of resources or time (stability- firmitas)

3. Damage to the wholeness- damage the wholeness of the central object's shape (beauty- Venustas)

Examples-

Thatch- *need- shelter from the rain.* Material- stone from the sidewalk, ropes, sticks and nylon.

Hot fish- *need-home to the fish. * material-kettle, fish, stones.

 Follow the flow-*need- adjust the flow * material-leaf.

Opuntia ficus-indica-*need- prevent climbing over the wall * material- fragments of glass bottle , concrete.
