Abstract
Abstract A solar energy collection and utilization system includes a reservoir having a heat transfer fluid stored therein, and a platform supported by the fluid. A solar energy collector is carried by the platform, the system further including a fluid conductor in the collector for receiving energy collected from solar radiation and heating the heat transfer fluid passing therethrough. Appropriate piping is provided between the reservoir and the fluid conductor such that the fluid heated by the collector is stored in the reservoir for subsequent use for heating applications, including methane generation in a separate facility.
