Patent attributes
A solar radiation redirection device includes an untethered balloon or balloon-like structure defining an inside volume. The balloon or balloon-like structure has a substantially transparent portion and a substantially reflective portion, wherein the substantially reflective portion is substantially parabolic in shape. The balloon or balloon-like structure also includes a secondary reflector located adjacent to the substantially transparent portion within the inside volume of the balloon or balloon-like structure. The substantially reflective portion is configured to receive solar radiation from an external source through the substantially transparent portion and concentrate the received solar radiation onto the secondary reflector. The secondary reflector is configured to direct the concentrated solar radiation towards a target, the target being external from the balloon or balloon-like structure.
