A small 5 kW water turbine based on the research of Dr. Mohammad Durali at MIT. According to the original development, the equipment would be used to feed an electrical network (coffee farm in South America), which is why they have selected a 60Hz generator, however, I believe that this can be adapted to the needs of whoever is going to replicate it. In any case, the same original design was followed.

Solar Water Heater with Serpentine Collector

Tubular Plastic Biodigester

Vertical Axis Sail Windmill - Diameter 3 m

Windmill Blades - Diameter 1.5 to 3 m

A solar water heater. Based on a manual published by WOT. It may be helpful in constructing solar collectors and building hot water systems especially for communities using large quantities of hot water.
