A reliable and covert power supply is essential for the autonomous operation of drones. However, a diesel generator is not suitable for this purpose as it generates a lot of noise and creates high thermal emissions. This results in a noise and heat signature that can be easily detected by modern drones, especially ones with thermal imagers, as well as by other means of reconnaissance.
Ensuring a continuous and undetectable power supply requires the use of a quiet and reliable power generator. At the same time, the system should be low-maintenance, as the locations where it is used are often difficult to access.
The EMILY Fuel Cell offers a mobile and off-grid power supply. It operates reliably, and completely emission-free, with a hard to detect heat and noise signature. These features make it the ideal solution for discreet use with a low risk of detection.
