Technical Self Reliance
Our Classification
Named technological Self Rliance (TSR)
Index calculated by multiplying tools or technology, possessed by a respondent by the efficiency rating claimed for the particular technology, resulting in the sum of the efficiency rating for each of the 25 tools.

The tools are:, 2. greenhouse, 3.root cellar, pond, 5. solar heat, 6.pigs, 7.wood lot, 8.wood stove heat, 9.wood stove cooking, 10.composting privy, 11.hydro-electric system, 12.graywater(waste water) water heater, 14.chickens, 15.goats, 16.beef cattle, 17.milk cow(s) 18.sheep, 19.wind power, 20.weeder geese, 21.bees, 22.fruit trees, 23.butcher larger anaimals, voltaic power, horses.

Efficiency is evaluated by asking the respondents about the effectiveness of the tool items of 'providing your family with independence or self-reliance from a one (not at all effective) to four(very effective point sequence.
The TSR index-scores have a theoretical range between 0-100
