Miyama Spiral Hydroelectric Generator and Miyama Hydro Cyberspot
Miyama Hydro Cyberspot
The electricity generated by Miyama helical hydroelectric generator, which is average 50w(changes depending on the amount of water flow), is stored in a battery and provided for visitors to use:
- free internet access with public Wi-Fi
- charging mobile phones and other IT tools.
※three types of inlet: AC100V, USB port, 12V ciger socket
Miyama Spiral Hydroelectric Generator
The “Spiral Water Mills” were originally designed by a blacksmith in Toyama Prefecture in the 1920s before they started to be manufactured for mass production in factories. More than 10,000 existed around the Hokuriku region at the peak of its popularity. Since they were easy to set-up and remove they were very efficient.
Advantages of the Spiral Water Mills include the fact that the rotation of the mill did not require any falling water, and also that the setting-up of these mills did not negatively affect the natural water flow of the pre-existing canals. They disappeared after WW2 due to the increased usage of fossil fuels.
Today, there is only one working mill located in Nanto city, Toyama. It was replicated by Fushimi Technical High School as a portable hydropower generator, which is a model of the prototype of the general-purpose hydropower generator made in Miyama, known as the Miyama Spiral Hydropower Generator.
We are continually trying our best to improve this system and to spread the use of this hydropower generator throughout the Miyama region.
