Changes

Technology Demonstration Centers are a very effective way of spreading knowledge on low-cost options in a given region. Because a technology always needs to be adapted to the local circumstances, preferences, materials and skills, in the ideal case each region should have a Technology Demonstration Center. There are not very many Technology Demonstration Centers around the world, and the spread of low-cost technology could receive a significant boost if more would come into being.
