In an effort to reduce the power consumption of a stand-alone domestic refrigerator an upright freezer, I will be adding additional insulation to standard units. A large amount of the heat gain (and thus heat to be pumped out), leaks…

An Outlook On Phase Change Materials
Phase Change Materials, usually abbreviated as PCM’s are wonderfully useful for thermal storage applications. These materials make it possible to store large amounts of heat relative to a substance’s mass. They do this in a similar way to the working…

The KillCap Refrigerator
As it stands right now, the machine I would most like to develop is a pedal powered refrigerator and possibly freezer. The compressor and drive mechanism will consist of a metal framework supporting a heavy flywheel perhaps 40 centimeters across…
