A small amount of LN2 would make a large volume of cold gas, and coupled with a folding solar dish, it w...

I "think" LTD is low-temperature-difference. If you look at picture galleries, the LTD Stirlings dont make much power (can run on the heat of your hand or a cup of coffee!). They need to emphasize heat exchange, so the displacer cylinder is a pancake. Why can't the hot and cold side be two...
