 P: 10 HEY GUYS... IM COMPLETELY NEW TO THIS FORUM AND AM AN AMATURE... SO BEAR WITH ME IF MY DOUBTS SOUNDS SILLY.... BY THE WAY IM IN MY FRESHMAN YEAR IN INDIA. I WANT TO MAKE A STIRLING ENGINE. PLS DO PROVIDE ME SOME GUIDING WEBSITES OR SUCH... NEXT I HAVE A DOUBT IN IT... IN A STIRLING ENGINE THE LIQUID IS HEATED BY A HEAT SOURCE... NOW MY QUESTION- I NOTICED THAT THE BOILING PT OF ACETALDEHYDE IS AROUND 20.6C. IF I PUMP LIQUID ACETALDEHYDE AT SOME 15 OR 10C CONDITION AND THEN IF I BRING THE STIRING ENGINE TO THE ROOM TEMP THEN WILL IT WORK WITHOUT AN EXTRA HEAT SOURCE AT THE ROOM TEMPERATURE.....?. OR MAYBE LIKE Geir Onsoyen SAYS MAYBE USING A LIQUID OF HIGH COEFF OF THERMAL EXPANSION, THEN WOULD IT BE WORKING BETTER? AND WILL IT BE EFFECIENT THAN THE COMBUSTION ENGINE IN TERMS OF COSTS TOO OWING TO THE RISING FUEL PRICES?
