Most of mountain lodges, which don't have utility power, are
causing serious environmental problems by polluting mountain
streams with excreta and garbage discharged untreated.
Owing to the subsidies from Chino City, the Mountain Lodge "Natsuzawa
Mineral Spa" introduced 4.9 kW PV power generation system and
2.1 kW wind power generation system.
Power generated is used for operating waste disposing tank for
excreta and garbage, and lighting guidepost for visitors.
In the Mountain Lodge "Natsuzawa Mineral Spa" located
at 2,060m above the ground in the Yatsugatake Ridge, the following
new energy supplies were installed: 48 PV panels on the cottage
roof, 28 panels on wall face not to be covered by snow, and
7 units of high efficiency 300W wind power generator on the
roof.
The wind power units are to be removed during winter. In consideration
of severe and variable mountain weather, storage batteries of
48V, 1,000Ah were installed in preparation for failure in PV
and wind power supply.
Electric power derived from new energy is used for operating
a combined disposal and treatment tank to process excreta and
garbage even at - 25 °C.
The treatment tank is of self-consistent type without discharging
waste, and processed water is used for lavatory. |
