My invention: A water-powered phone.
The phone will be run by water, without batteries. The phone must be waterproof. The phone will be spilt into two compartments, one where the hardwares are (like hard-drive, screen) while the other will contain water and the mechanism that converts water to energy.
- No need to charge,
- Environmentally friendly.
- Danger of water leakage,
- The material used to hold the water must be strong. As if the phone is dropped, the water container might break.
