I would like to express sincere mourning tothe Srilanka Tsunami Disaster.
2004, 26th Dec.Tsunami attacked the wholeSrilanka Shoreline, 31,000 people died,500,000 people lost home, 78,000 houses
destroyed, 40,000 houses damaged.

Report from Fukushima 2015

Seamen has lost their sea,
farmers have lost their lands,
merchants have lost their markets,
not by their own will.
Families have been separated to live inseveral houses, their communities havebeen separated in many areas.
In the year 2015, still 130,000 people
have lived apart from home.

Report from Fukushima 2015

The city governments have built the15m high retaining walls to defend
against the next tsunami, which, will
attack on hundreds years later.
By its tremendous disaster, the tsunami
and Nuclear Electricity generation
plants burst accident, the people
escaped from their houses, without anybelongings.

Many reconstruction demand increased,
It’s a development babble.
The construction cost has been higher,lack of workers, rejection new work, etc.
Recover housing development started
in public, very few in private houses.
Because of their lost property
by Tsunami and Nuclear Accident.

After the disaster, I wanted to stretch out helping hands not only for getting the spiritualrelief, but also for getting the economical affordability, by the land rent with the elevatedsky solar system.

The electric consumption per capita in 2010
is.4.2mwh/y for average family.
Tokyo demand 154,000,000mwh/ySo-so(N-E)

6,150mw
Wind

I was confident the power of therenewable energy is enough,and no need of Nuclear Power.
Srilanka has tremendouscapacity, by strong sun andocean wind and wave.

Development for Sky Solar System

to make double effect for solar generation and free activity

The development criteria for the Sky Solar System:
・In Japan, the area capacity of the flat lands for normal solar panel on the ground Is very small,and competitive with normal land use.
・Normal Solar System needs land fill, cut and dig roots, and leveling the land, therefore, the cost for
the land formation is high.
・The cost for the preparation against the natural menace like earthquake, tsunami and typhoon is
also very high, because normal type is not needed to check the structural standard.
・The solar panels put on the ground is needed to prohibit the people’s entering into the site.
・Elevated Solar Panels is needed to be adapted to the low of the standard of the architecture in order
to arrow the people enter underneath the panels.
Could you hand your land to the solar panel single use in the 20 years?

Sky Solar System allows the multiple land use, and make the shade for theland be cool, make the desert land be green, and change the land to thepark, road, car parking, agricultural development for the people.

3. Scope of the world wide contributionA) Wares of Great Britain,
I was invited by the peace group of the Wares, and gave some idea to develop
the renewable energy in the Anglesey Island as “Natural Energy Island”,
and appealed to the people not to redevelop the renewal of the nuclear
generation plant.
B) the desert of Cairo, Egypt,
I proposed the idea to develop the Sky Solar System on the desert skirt along
Nile river.
The space structure along the Nile, built environment are built along the river,and over the city area, the huge area of the sand desert area cover the land.

If the Sky Solar System is developed in this fringe area, the shaded area willbe spread to the desert, and green vegetable will be produced under the solarpanels.
This idea will encourage both to accelerate the natural energy development inthe sky and to promote the greening the land to the agricultural farming for thepeople.

These idea is to create the shaded area under the solar panels
And to create multiple activity land use, which will be more usefulin the tropical area, Asia monsoon, and desert area.
