Canadian scientists have recently developed a device that allows people to generate and store electricity through the movement of their jaws when they speak or eat. The subject wears the device and chews gum continuously for 60 seconds, and a cord close to the chin can produce about 10 Microwatts to 18 microwatts of electricity, and an average of about 7 microwatts per meal when chewing food. It is expected that this improved method of power generation may be used in the future to charge hearing aids, smart hearing protectors and even small electronic devices such as mobile phones. What does the following statement inconsistent with the original? ['Newly researched power generation method can be used for hearing aid charging.', 'Canadian scientists have developed a device that allows the body to generate and store electrical energy through exercise.', 'Chewing gum continuously for 60 seconds can produce 10-18 microwatts of electricity.', 'People speak or eat to generate electricity.']
