to achieve optimal performance from the pump and filter it is necessary to
install them upright. The frame on the second prototype was redesigned to
accommodate an upright installation of both the pump and filter.
4 Current Outcome of Technical Implementation
Both TGER prototypes underwent a third party assessment conducted by the US
Army Aberdeen Test Center. Three high risk and five medium risk hazards were
identified on the TGERs. All risks were mitigated with minor hardware modifica-
tions, and sufficient safety devices and equipment were supplied as part of the basic
issue items (BII). 007-DT-ATC-REFXX-D5104
Given that the mission of the Rapid Equipping Force is to quickly respond to
field commanders' requests by accelerating new technologies, the two first stage
TGER prototypes were deployed by intent at what was considered to be the mini-
mum technical readiness level for field evaluation. TGER assessment during the
90 day deployment to Victory Base Camp, Iraq met its objectives by identifying the
key engineering challenges needed to advance from a first stage scientific prototype
to an acquisition candidate system (Fig. 8).
The Iraq deployment validated the utility of the TGER system as an efficient
means to address a complex, mixed, wet and dry waste stream while producing
power. The science and technology underlying the hybrid design of the TGER is
unique and has considerable advantages over other unitary approaches. The engi-
neering of the TGER system and, in particular, the difficulties which arose in having
to modify third-party commercial off the shelf equipment to TGER purposes, were
an expected and commensurate problem.
Overall, the TGER performed well as a system for the first month of deployment.
During the second month, unanticipated problems with the downdraft gasifier arose
