20140283815 | SOLAR COLLECTOR - A solar collector is made primarily of plastic materials. A wide variety of collector configurations may be made from similar parts, and thus the collector may be adapted to mount in locations where traditional flat panel collectors may not be feasible. The collector may conveniently be used with a nanofluid as the heat transfer fluid, to increase the heat transfer characteristics of the heat transfer fluid. A control system for stagnation remediation, freeze protection, or both may be utilized. For example, when the collector is in danger for stagnation or freezing, water may be circulated through a ground coupled heat exchange loop to cool or heat the collector. Preferably, the stagnation remediation mode does not sacrifice thermal energy previously collected and stored. | 09-25-2014 |
20120199171 | THERMOELECTRIC GENERATION UTILIZING NANOFLUID - According to one aspect, a system generates electricity from a temperature differential using a thermoelectric module. At least one side of the temperature differential is supplied by a thermal element having a fluid flowing through it. The fluid contains suspended nanoparticles to enhance the transfer of heat between the fluid containing the nanoparticles and the thermal element, as compared with a similar fluid not containing the nanoparticles. The nanoparticles may include metal ions, for example silver ions, copper ions, or both. The system may further include an ion generator for generating the ions within the fluid. | 08-09-2012 |
