N1 - Funding Information:
This review was part of a larger project to review methods for reducing carnivore–livestock conflicts in Norway, financed by the Norwegian Directorate for Nature Management and the Ministry of Agriculture. The Nord-Trøndelag County Governor’s Office, Environmental Department, provided additional funding for the USA tour. Special thanks are extended to Inger Hansen for inviting us along on her trip to the USA and to Roger Woodruff for planning and guiding us through an extremely informative tour. Thanks also to the personnel of the National Wildlife Research Center, Fort Collins, CO, for an informative tour of their facility. Editorial comments are gratefully acknowledged from Roger Woodruff, Lorna and Ray Coppinger, Inger Hansen and William Andelt.

N2 - This work discusses the operation of a capillary-driven two-phase loop, configured on a micro capillary pumped loop (MCPL) system without an external power supply but capable of automatic heat transmission. The MCPL device, fabricated using MEMS (microelectricomechanical system) technology, was tested and yielded the following results: first, the proposed design of a new MCPL system with a water reservoir operating at low pressures is feasible and requires no additional power supply and instead relies on automatic heat transmission. Second, the issue of depriming in a MCPL was effectively controlled, the endurance of MCPL for the depriming problem can be executed by yielding input heat fluxes of 185.2 W/cm2 at an evaporator temperature of 165 °C, thus revealing that this model provides excellent cooling performance. Third, the effective operation range was determined and its successful operation was confirmed for MCPL. The ease of starting up increased with the temperature of the reservoir. Finally, two-phase tension that originated in the groove structures in the evaporator and condenser was confirmed to control the movement of the fluids throughout the system and verified to be effective in improving cooling efficiency.
