A system and method for energy harvesting in a data center has one or more collection devices, a thermoelectric device, and a controller for directing the operation of the thermoelectric device and other equipment in the data center. The waste heat generated by the servers in the data center is harnessed and directed into the thermoelectric device where the waste heat is converted to usable electrical energy under the direction of the controller. The recycled electrical energy is then combined with utility-input power and provided to the servers and other equipment in the data center for consumption.

A catheter has a cooling distal section for freezing tissue to sub-zero temperatures with one or more miniature reverse thermoelectric or Peltier elements, also referred to herein as micro-Peltier cooling (MPC) units or electrodes. The MPC units may be on outer surface of an inflatable or balloon member or a tip electrode shell wall that has a fluid-containing interior cavity acting as a heat sink. Each MPC unit has a hot junction and a cold junction whose temperatures are regulated by the heat sink, and a voltage/current applied to the MPC units. A temperature differential of about 70 degrees Celsius may be achieved between the hot and cold junctions for extreme cooling, especially where the MPC units include semiconductor materials with high Peltier co-efficients. An outer coating of thermally-conductive but electrically-insulative material seals the MPC units to prevent unintended current paths through the MPC units.

A sensing system including in-ground sensors not requiring battery power. A thermoelectric generator sensor rod includes an upper thermal contact and a lower thermal contact at or near its two ends. When the thermoelectric generator sensor rod is buried in the ground with one end buried more deeply than the other, a temperature gradient in the soil produces a temperature difference between the upper thermal contact and the lower thermal contact. The upper thermal contact and the lower thermal contact are thermally connected to a thermoelectric generator, e.g., by heat pipes or thermally conductive rods. Electrical power generated by the thermoelectric generator powers sensors for monitoring conditions in the ground, and circuitry for transmitting sensor data to a central data processing system.
