Claim 6:
7. A solar energy utilization device comprising:
two plate members that include a first transparent plate member and a second transparent plate member disposed substantially parallel to the first transparent plate member;
a transparent first triangular prism that is disposed between the two plate members and is composed of a first side along the second transparent plate member in a cross-sectional view, and second and third sides; and
an energy collection portion that is installed with a predetermined gap interposed between the energy collection portion and an entirety of the second side and collects solar energy,
wherein the transparent first triangular prism comprises a refractive index and is arranged such that internal angles of the transparent first triangular prism form three types of optical paths of sunlight that has passed through the second transparent plate member and entered into the transparent first triangular prism from the first side, the three types of optical paths including an optical path along which the sunlight that directly reaches the second side and goes out of the transparent first triangular prism from the second side, an optical path along which the sunlight that is fully reflected at the third side, reaches the second side, and goes out of the transparent first triangular prism from the second side, and an optical path along which the sunlight is fully reflected at the third side and the first side in order, and then reaches the second side and goes out of the transparent first triangular prism from the second side,
wherein the solar energy utilization device further comprises a transparent second triangular prism that is the same shape as the transparent first triangular prism in cross-sectional view, is composed of a fourth side and fifth and sixth sides, and is disposed such that the transparent second triangular prism is inverted mirrored image of the transparent first triangular prism in a direction in which the energy collection portion is therebetween the transparent first triangular prism and the second transparent triangular prism,
wherein the energy collection portion is provided between the second side and the fifth side and is separated from both the second side and the fifth side,
wherein a vacuum layer is formed between the second side of the transparent first triangular prism and the fifth side of the transparent second triangular prism, and
wherein the energy collection portion is provided in the vacuum layer, and
wherein the solar energy utilization device further comprises a moving mechanism that moves the energy collection portion between the second side and the fifth side and allows the energy collection portion to be separated from the second side and the fifth side.
