Maximizing a Small-Scale, High-Capacity, and High-Efficiency APSA System

For effective DR operation, it is crucial to integrate the APSA process, which uses adsorbent materials to capture gases essential for firefighting: nitrogen displaces oxygen, and carbon dioxide suffocates flames. Our advanced APSA system employs a 3-layer adsorbing matrix—alkaline pyrogallic acid, palladium, and zeolite—to absorb oxygen, hydrogen, nitrogen and carbon dioxide. Current adsorbents lack the capacity and selectivity for efficient gas capture under rapid cycling conditions. Advancements in nano-engineered adsorbents with higher porosity and hybrid materials are needed. Additionally, low-energy desorption techniques will enable quick regeneration. Optimizing APSA for faster, eco-friendly wildfire suppression requires breakthroughs in real-time gas separation and the use of high-capacity compressors.

Thermoelectric and Hydrogen-Powered Drone for Extended Operation

A key challenge for DR is providing autonomous, sustainable power for longer flight times to suppress fires continuously. DR uses thermoelectricity and hydrogen fuel for extended operations. However, TEG efficiency is low compared to other power sources and relies on temperature differences and the materials used. A large temperature difference is needed to generate enough electricity. A breakthrough is needed to improve TEG efficiency and enable easy, efficient electrochemical processing of hydrogen/oxygen inside a small drone to produce the necessary power.
