This pull quote, which is discussing electric motors, makes no sense.
- nine_k 5y agoMaybe they mean the cost of production if the motor? A copy-editing blunder, though.

- dreamcompiler 5y agoThey're talking about less carbon being emitted by the generators of the electricity to run the motor, because the motor is more efficient than others of equivalent rotational power. No idea if this is true, but I think it's what they mean.
- Animats 5y agoemits at least 25 percent less carbon. Brush wear?
- mschuster91 5y agoPer [1], even if dated a bit, the efficiency of motors can be improved by 20-30% - which means that assuming a fossil powered electricity source the amount of energy consumed and CO2 produced will be lowered correspondingly, simply because you need 20-30% less electricity for the same power output on the axis. Additional energy and CO2 will be saved by lower system weight (especially if the motor ends up being used in a mobile application like a car or train) and by lower system size.
