PURPOSE: To collect the invisible energy existing in the cosmic space and to make improvement in the quality of food, etc., by providing 1st and 2nd triangular colored annular band wire groups concentrically formed with plural pieces of triangular colored annular band wires on the surface of a display plate so as to have 60° phase difference.
CONSTITUTION: Two sheets each of 1st and 2nd collecting plates 1, 2 are disposed respectively in diagonal directions on a supporting plate 5 consisting of timber or acrylic resin, etc., and 3rd collecting plates 3 made of metals are disposed between the respective collecting plates 1, 2 and the supporting plate 5. A 4th collecting plate 4 which is rotated by the rotation of a motor 7 is disposed in the central upper part of the supporting plate 5. The respective collecting plates 1, 2 are substantially similarly constituted and plural pieces of the triangular colored annular band wires are concentrically formed on the surfaces. The 1st and 2nd triangular colored annular band wire groups 14a to 14g; 15a to 15g which are changed stepwise in the lightness of coloration from the outer side toward the inner side are formed to have 60° phase difference. The quality of the water and food in a container placed in the upper part is improved by the cosmic energy.
