How cold does the cooling side need to be?
They are cooling it with either well water or water out of a pond.
I thought if required I could just take a fairly large cooler of ice everyday to provide the cooling, or invest in a large number of heat sinks and have the fan blow air across those, design will have to be considerable different though than the videos.
Here is a full length video of everything one company is doing in Portugal with LTD stirlings, but they are using vegetable oil at 100-200C, our boilers produce around 90-95C? Hence need even better cooling to maintain a larger heat differential. Would really hate to have enough dry ice around for 4 days of cooling over Labor Day. Or, with a lower differential need even a larger displacement engine. Another interesting thing I’ve found is instead of a crankshaft to run the displacer a cam can be used instead to achieve a much longer dwell time of the displacer resulting in the working gas being in contact with the hot and cool sides longer which should increase efficiency.
