Second Place (2024): USAV - Ultrasonic/Sensing Active Vent

Who Let The Gas Out Challenge for NASA at FreeLancer.com.
This Challenge is seeking solutions to propellant tank venting in micro-gravity with minimal loss of propellant. Although all concepts will be considered, solutions that are external to the propellant tank are preferred as they could use existing (heritage) propellant tanks and avoid development costs related to designing and qualifying a new (or modified) tank.

We proposed the 2-4 kg Ultrasonic/Sensing Active Vent (USAV) that employed our Motosonics concepts. Happy to discuss with interested parties. 

Second Place (2022): ASEAR - Automated Sonically Enhanced Ash Removal

Proposed for NASA's "Trash-to-Gas Ash Management" Challenge.
Trash-to-gas reactors are considered a sustainable approach to both near- and long-term waste management during long-duration space missions. The primary goal of this challenge was to create actionable design concepts for ash removal from a trash-to-gas reactor in microgravity. The solution used Motosonics concepts with CO2 reused from the CO2 scrubbers on the spacecraft. Visualization examples available on request. 

Fourth Place (2023): GIPS - Gravity Independent Particle Separator

Proposed for NASA's Particle Partition Challenge.
This challenge seeks to identify novel ways that fine carbon particles can be safely and efficiently removed from a Bosch reactor (used to recycle CO2 back to O2), without impacting the reactor’s performance. This solution incorporated Motosonics speakers to enhance efficiency. Won 4th place.
