IWTSD Wazoku Crowd Challenge: Power Drain Technology

The U.S. Irregular Warfare Technical Support Directorate (IWTSD) has launched a pioneering Wazoku Crowd Challenge to discover innovative technologies capable of remotely draining power from batteries and electrical storage devices, such as capacitors, without physical contact. This technology also requires the capability to measure the remaining power level to ensure the deactivation of threats such as Improvised Explosive Devices (IEDs).

Explore the Recent Challenge


Develop a non-contact method to safely drain and measure the power from batteries and capacitors.


Directly enhances the safety of military personnel and civilians by neutralizing IEDs without physical interaction.

Innovation Gap

Unlike existing technologies that allow for wireless charging, there is no known solution for over-the-air power draining and measurement.

The Problem we are trying to solve

IEDs, which often utilize a small power source like a battery or capacitor, pose a constant threat in various environments. A technology that can deactivate these devices from a distance by draining their power sources would be a groundbreaking advancement in safety and tactical operations.

The Challenge

Drain Power Remotely: Effectively deplete energy from a variety of battery and capacitor types via a non-contact approach.

Measure Power Levels Remotely: Accurately assess the remaining energy without needing to physically interact with the device.


The Irregular Warfare Technical Support Directorate is dedicated to identifying and deploying rapid prototyping of novel solutions for challenges faced in Irregular Warfare. This recently-closed challenge is part of IWTSD’s commitment to fostering innovation and collaboration across various sectors to enhance tactical and operational capabilities.
