 Fiber Optic Sunlight Collecting System - "HIMAWARI "
The HIMAWARI Sunlight system is composed of 3 parts;
- "Collector" to track and collect sunlight,
- "Optical fiber cable" to transmit sunlight and
- "Cable terminal and lighting appliance."

| The inventor of the HIMAWARI system : |
The late Dr.Kei Mori (1932 - 1990)
The late Dr.K.Mori, the then professor of the Department
of Science and Engineering in Keio University,
invented the sunlight collecting system and named it
HIMAWARI after the "sunflower" in Japanese.
He intended to enable all the living things on the earth
to enjoy much more favour of the sun.
Nowadays, there is an acute demand on the
technological
developments to harmonize the economy with
the envioronment.
His invention of HIMAWARI promises many answers
to
those problems as energy saving, natural alternative enrgy,
global-warming and disposal of wastes and
effluents.
La Foret Enginnering Co. Ltd. is striving
hard in materializing
the will of the late Dr.k.Mori and in contributing to the mankind
with the abundance of the sun . |

| Particularly interesting experiments were conducted by the late
Dr. Kei Mori of Kao University in Tokyo. Dr. Mori raised plants under special light that filtered out IR and UV radiation. His unique process of fiberoptic sunlight collection and transmission, called "Himawari Sunlighting" (bottom left), is now marketed worldwide. At first Mori feared the filtered light would be detrimental. But after extensive experiments he claimed it could promote healing and "because the ultraviolet is blocked, this sunlight does not fade fabrics or damage skin." (Gilmore, Elaine, "Sunflower over Tokyo," Popular Science, May 1988, p. 75.) One long-lived tomato plant (shown right) was grown in a special nutrient-rich solution to be exhibited at the Japan Expo 85. Under piped sunlight and controlled atmosphere, this tomato tree grew over 30 ft high and yielded more than 13,000 ripe tomatoes during the six months of the Expo! (Hiroshi, Koichibara, "Tomatomation," UNESCO Courier, March 1987.) Could Moris environment of filtered sunlight, enhanced carbon dioxide, and nutrient-rich liquids mirror the conditions on the early earth?
