- | |||
- | * Is the air pump giving more than what it pumps in terms of energy ? | ||
- | * Could we make a mechanical airpump coupled with a windmill ? | ||
- | * Could we improve the cathode design to remove the airpump ? | ||

+ | * Is the electric air pump giving more energy than what it pumps ? | ||
+ | * Most probably not. | ||
+ | * Could we make a mechanical airpump coupled with a windmill ? | ||
+ | * Probably. But how useful would this be ? We should maybe focus on gathering the energy of the windmill. | ||
+ | * Could we improve the cathode design to remove the airpump ? | ||
