We can do a re-think on how the TX device can be kept passive with no
power consumption and all the electronics in the receiver itself. For
example a bar coded page mounted on a board, that the user simply downloads into his device using a bar code reader. Another option is to eliminate the use of any device for receiving and make a pole mounted
kiosk that has a built in keyboard and speakers for interactive queries, like a public telephone. This kiosk will be powered on only when a user presses a button.
Use foot power. Place something similar to a dynamo under some tiles on the sidewalk or on the road. As cars or people step on this, it will generate power which will be used to charge the battery.
Similarly, is it possible to harness the underground drain water to run a small watermill?
