Space Thermoacoustic Refrigerator
The Space Thermoacoustic Refrigerator (STAR) was designed and built by a team at the Naval Postgraduate School led by Steve Garrett. It has the ability to move about 5 Watts of heat and exhibited a peak coefficient of performance relative to Carnot (COPR) across the stack of about 20%. A good paper about the STAR project is "Thermoacoustic Refrigerator for Space Applications."

Pacemaker Code Chart
Positions I, II, and III identify the chamber paced, chamber sensed, and mode of
response to conventional (P- and/or R-wave) sensing, respectively. The fourth position
indicates rate modulation (adaptive-rate pacing).

Direct Methanol Fuel Cell (DMFC)
Direct Methanol Fuel Cell (DMFC) is a fuel cell that runs directly on methanol (or various liquid fuels) without having to first convert those fuels into hydrogen gas. It consists of two electrodes separated by a proton exchange membrane (PEM) and connected via an external circuit that allows the conversion of free energy from the chemical reaction of methanol with air or oxygen to be directly converted into electrical energy.
