Desert Storm indicated that portable lightweight miniature electrical generators are needed for combat field operations. Mainstream has previously developed a JP-8 (multi-fuel) 53 pound 1kW portable diesel electrical generator under a prior Army BAA effort. This Phase I will extend this development effort to demonstrate that based on the results of this earlier hardware development and additional IR&D by Mainstream we feel confident that we can demonstrate a 1 kW unit with a system weight below 40 pounds. This Phase I effort will demonstrate the performance of a prototype system.The proposed effort includes the detailed redesign and fabrication of selected components of Mainstream's existing 53 pound multi-fuel 1 kW diesel generator to provide a demonstration unit which weighs less than 40 pounds. The generator will be configured as a portable unit for easy carrying to the point of use, where it could be set-up to provide continuous, relatively-quiet electrical power. The Phase I will demonstrate the Mainstream's unit meets the Navy's performance, weight, size, fuel economy, reliability, maintainability, and noise requirements. Phase II will include a further refinements and deliverable of prototype units for extensive field tests. This Phase I effort will demonstrate an innovative, compact multi-fuel diesel generator that has tremendous marine, disaster relief, and industrial niche market applications where the safety and stability of diesel fuel over gasoline represents a significant advantage. Mainstream has already committed it own resources and secured a commercialization partner. Our marketing studies have indicated a substantial marine and disaster relief niche market.
