秒删了一贴。难受。

Steam engines would only produce 'mechanical' power, and this wouldn't be added to a pool in the vehicle but only transmitted through shafts. This Mechanical power could then be transferred to electrical power at will with the already implemented generators.
蒸汽引擎只产生机械能。机械能不加入到载具的“动力池”，而是通过轴传递。机械能通过已有的发电机模块转化为电能。
All current blocks that consume engine power would be changed to consume electrical power instead, and Electrical Engines would convert stored Electrical power into Mechanical power at a small loss.
所有消耗引擎功率的方块改为消耗电能，电机方块改为将储存的电能转化为机械能。
Spinblocks would have two modes. They would either consuming electrical power dependant on mass of the sub construct on them and speed of rotation, but would have a max 'load', and would either be best for low-speed but medium weight, or medium speed/low weight application. Or they would connect to a source of mechanical power for no max load so long as enough power was supplied, with more power meaning more weight or rotation speed.
旋转方块改为两种模式。消耗电能的模式适合小载重中速或中载重慢速的应用，直接连接到轴上消耗机械能的模式适合更大载重，更高速度的应用。
This would all add up to more (And more importantly, interesting) design considerations while simplifying and streamlining how the game work, and having a single energy type would free up balancing for many other systems.
以上内容应该能增加更多的设计考量，同时简化游戏构架。单一的引擎形式也方便省去在不同引擎形式之间平衡的麻烦

算了 原帖请去论坛看。
本质来说，游戏的动力系统是将物质转化为能量。游戏尝试着模拟了三种常用的舰用动力系统——柴油机，蒸汽机，蒸汽轮机。
目前柴油机有一套复杂——有趣的搭建系统，需要在各种部件和功能之间做出取舍，在游戏性上比较不错。
蒸汽机和蒸汽轮机完成度太低。蒸汽轮机除了发电以外没有作用。

蒸汽机加载的时候阻力会变大，导致转速变慢，这会影响推进。希望的解决方案是增加一个优先级设定，某个齿轮箱只用作推进/某个齿轮箱提供动力/优先扣除电动力/优先应用柴油机的动力之类。
