What are inventions or prototypes of different artificial pollinators?

Question

There is a need for pollinators after a large extinction of honey bees in some regions, so what are some prototypes or different inventions of these artificial pollinators? Also, what are some possible costs of the inventor and/or the investor?

Answer 1

Sprayed water is an efficient pollinator for some plants. Brushes can be used but are labor intensive. Invest your money in saving bees, they do it best.
