*Researched boiler systems (watertube, monotube, firetube, etc)--on-going
*COTS engines found to date do not meet specs (size/hp requirements) and seem to be costly, though design from http://www.mikebrownsolutions.com/techinfo.htm is intriguing (20 hp engine/150 lbs)
*Notes about safety--need to ensure sufficient safety warnings and instructions are included in manuals/drawings/maintenance plans--significant risk for safety incident (to include notes wrt substitutions of lower performing boiler safety valves, etc)
*Created QRL for supply/SMEs/resources
*Project plan--top level summary/intent/etc and outline
*Followed up on Pure Energy Systems--Massachusetts-based firm does not seem to exist. However, there is a Pure Energy Systems wiki that contains a lot of great information about renewable/sustainable energy: http://peswiki.com/index.php/Main_Page

*Performed research on history of product from initial innovation to modern use
*Analysis of alternatives:
*Began technical analysis requirements: COTS availability analysis, independent innovation, & alternatives
**Researched bump valve reliability, researching alternative solutions
*Reviewed product integration requirements--began drafting tech performance requirements/specs
**Need to discuss condensation issue and air compression issue on the return stroke (sending note to M. Norton)
**Noted comments in blogs wrt regulation requirements in some states in the US
**Power vs pressure: The higher the pressure, the smaller and lighter the engine (weight to power ration)...optimum pressure for SWAP requirements?? Include risk analysis (higher pressure/heat = higher safety risks), probable effect on cost. Continue researching.
*Collecting potential SMEs (orgs & individuals) list and contact information for possible recruitment
*Drafted outline for project plan:  
#Product Description, Operational Concept, and Operational Requirements
#Product Cost Requirements
#Program Schedule
#Life Cycle Sustainment Requirements - maintainability, safety, human performance/human engineering, testability
#Manpower - System Development/Build Requirements, System Operator Requirements, System Maintenance Requirements
