Remote Power Delivery, Heating, and Cooling Via Optical Fibers

This invention is a method for remote power delivery, heating, and cooling that leverages lasers and optical fibers for use in locations where traditional electrical systems are impractical. High-power laser light is transmitted through optical fibers—single-mode, multi-mode, or double-cladding—to remote locations, where thermoelectric generators (TEGs) and photovoltaic detectors convert the laser light into electrical energy. This system not only provides reliable power but also enables precise remote heating and cooling through thermoelectric cooling (TEC) systems. It also allows for optical communications and temperature sensing all through a single fiber, making it a practical solution for applications with areas that are difficult to access without relying on bulky electrical cables, such as aerospace or deep-sea exploration. With its low-loss optical fiber transmission and electromagnetic interference (EMI) immunity, the invention offers a scalable, lightweight, and energy-efficient solution for long-distance operations.

Background: 
Traditional power systems often face challenges like voltage drops, overheating, electromagnetic interference (EMI), and the need for heavy cables. While current thermoelectric and photovoltaic technologies convert waste heat and sunlight into electricity, they usually come with low efficiency or limited power output. This technology overcomes these issues by using lasers and fiber optics to deliver more reliable power and control temperature remotely. While previous approaches to remote power delivery using optical fibers have focused on isolated capabilities, such as photovoltaic power conversion, this invention integrates multiple functionalities—power delivery, heating/cooling, sensing, and communication—into a single fiber solution.

Applications: 

• Aerospace (aircraft, spacecraft)
• Tethered Drone or Balloon Powering
• Space and Planet Exploration and Distributed Sensors with Centralized Power (Earth, Moon, Mars, etc.)

• Remote industrial sites
• Telecommunications
• Environmental monitoring

Advantages: 

• Delivers high power over long distances with minimal loss
• No need for large and heavy electrical cables
• Electromagnetic interference immunity
• Enables remote temperature control and monitoring
• Centralized power distribution to multiple locations (planet exploration)
• Can utilize existing fiber infrastructure, lowering installation costs
• Avoids localized heating along the power transfer route
