70. Conclusion It’s a well thought product. It has proven his utility. Difficulttooptimize, the principle is alreadyusedfor decades. What do they do now: flywheelandclutchplateoptimization. The future? Does anelectriccaruse a clutch? A CAR CLUTCH For dummies Thijs Leroy 23 dec 2010 Constructieleer 19/19
