  • Vertical Axis Savonius-type Wind Turbine Type D

A tough, small wind turbine that can be used as an
emergency power source during disasters.

Vertical Axis Savonius-type
Wind Turbine Type D

TypeD

Features

Since it is wind powered, it can generate
electricity 24 hours a day.
Ideal as an emergency power source in times of
disaster at evacuation facilities such as schools
and parks, and as part of BCP* measures for
companies.

*Business Continuity Planning, in the event of an emergency
Its lights use the electricity generated, so they illuminate during normal circumstances
and in times of disaster.
It can also be used to directly charge smartphones and other devices from its built-in
USB port as an emergency power source.

Compact design allows installation in
a wide
range of locations.

Space required for installation:
4.4m2
It is also effective as part of BCP measures in the following locations.
  • Evacuation facilities
  • Disaster prevention parks
  • Coastal areas
  • River beds
  • Observatories

Technology

Thanks to a unique wind turbine design* it generates electricity surprisingly
quietly, regardless of wind direction.

*Patent pending.

  • Noise level

    49
    dB

    The same level as that of a household air conditioner or a ventilation fan. The structure is designed to minimize unpleasant noise.

    ※Measured at a distance of 1m from the wind turbine at a wind speed of 7m/s.

  • Withstandable
    wind speed

    40
    m/s

    A structure capable of withstanding strong winds equivalent to those of strong typhoons, that may cause trees to fall or houses to collapse.

  • Rated output

    100
    w

    Power generation at wind speed of 11m/s

  • Maximum
    output

    250
    w

    Power generation at wind speed of 14.5m/s

Type D’s range of wind speeds for
power generation

3
m/s-14.5m/s
TypeD

It has a ‘People Friendly’ design and can
be installed anywhere.

Low noise

It is a quiet wind turbine that does not generate unpleasant noises.

Low rotational speed

It is a safe wind turbine that rotates slowly and does not cause any sense of fear.

Demonstration Experiment

SETAGAYA Qs-GARDEN

We have started our demonstration experiment at SETAGAYA Qs-GARDEN in Setagaya Ward, aiming to the realization of wind power generation systems that can be installed in densely populated residential areas.

Step

Introduction process

  • 1
    Basic concept and consideration of potential installation locations
    Study of wind conditions, etc., confirmation of wind conditions and topography at the installation location.
  • 2
    Preliminary study (wind conditions study, ground study)
    Confirm whether there has been a past ground study near the considered location and conduct a soil boring test. Estimate the power generation based on wind data, planning the installation of the wind turbine(s), and determining the system configuration.
  • 3
    Wind turbine installation contract
    Conclusion of contracts regarding costs, schedule, maintenance, etc.
  • 4
    Construction
    Finished approximately 1 month within the conclusion of the installation contract.
  • 5
    Beginning of operation
    Beginning of maintenance inspections (annual visual check/lubrication).
