charge cell phone with water ppt

[simran]

This charger is intended to recharge the phone's battery with water.
The PowerTrekk system is a lightweight, brick-sized fuel cell charger powered by the good old H2O.
To charge the phone, users simply pour water into the tray, place a PowerPukk cartridge in the tray, cover the system, and then connect a phone with a USB cable.
Mineral water, salt water or dirty water from streams / puddles (as long as it does not contain sediment) are okay to power the device.
