Plans for scaled-up versions of demonstration models will allow significant power generation, and may allow development of other applications, such as water extraction or distillation, and agriculture or horticulture.
Between the 18th and early 20th centuries, demonstration models were also in use at universities and engineering schools, frequently designed and built by students as part of their curriculum.
Most of them are demonstration models that illustrate various aspects of electricity, acoustics, light, magnetism, thermodynamics, and weights and measures.
