Abstract
A thermal energy conversion device includes a heat converter composed of a medium containing portion ( ) that does not substantially change in capacity and a variable portion ( ) that is changeable in capacity, an operating portion composed of a piston ( ), a pivot lever ( ), and a driving lever ( ), a first conversion and storage portion formed of a movement barrel ( ), and a second conversion and storage portion formed of a power generator ( ). When the ambient temperature changes, heating medium contained in the medium containing portion ( ) changes in volume, and the capacity of the variable portion ( ) is changed, thereby operating the piston ( ). Motion of the piston ( ) is stored in a mainspring disposed in the movement barrel ( ) via the pivot lever ( ) and the driving lever ( ), and power is generated in the power generator ( ).
