Engine performance (An example)This is a first engine which produced as Solar Stirling Engine in our laboratory , study of it is beginning just now. On experiments up to now, we got maximum shaft power 6W with heated by electric valves. When the engine ran with actual solar heat in winter, we couldn't get the shaft power.
With a current design, by heat loss depending on a heat radiation/transfer and an element arrangement of positions, we think that big improvement in output can't hope it. From now on, whether we drastically improve this engine or design it newly, with a view to increasing the power.
