MEMS Rotary
Engine Power System
Project (MEMS REPS)
 |
Introduction:
The goal of
the MEMS Rotary Engine Power System (MEMS REPS) is to develop an autonomous,
commercially viable, portable power system based on an integrated AC generator
and rotary internal combustion engine. This engine will have an energy density
of 2300 W-hr/kg with a continuous power output of 30mW, which represents a 5x to
16x increase over commercial off-the-shelf (COTS) batteries (alkaline,
lithium-ion and zinc-air). The design also allows for rapid field implementation
in a variety of applications requiring localized power generation in the range
of 10 to 500 milliwatts. Applications include interconnected sensor networks or
land warrior power supplies.
The MEMS Rotary Engine Power System program under development at UCB
incorporates many sub-projects to address much of the ancillary equipment
necessary in order to more fully develop thermally driven power supplies at the
micro-scale. These development projects include an integrated electric
generator, fuel delivery system, SiC surface coatings, and thermal packaging.
