In addition this is a very good educational device for the city schools because children should learn how easy it is to be self-reliant and how simple it is to start tackling the enrgy problem. People who are not poor in cities should also shift to alternate energy like pedal power, wind turbines, solar etc as they are otherwise burdening some other person or environment for their consumption. In fact like we have mentioned, poor people are paying much more cost per unit of electricity. People in cities should therefore feel happy to try alternatives in solidarity with the poor, and have a change in life-style. In pedal power we want to try LED lights.
More work is needed in the front of batteries.
For example, circuits that switch off when battery power is low and prevent over-discharge need to be made and more easily available in rural areas. This has to be addressed. Alternate energy has to also be connected with local livelihoods. Solar PV technology is high-tech. and not much use for villages or even small cities in terms of generating livelihoods there. On the other hand things like pedalpower, windmills, biodiesel run engines can generate employment at the level of towns.
