My ideas of 'aatma nirbhar' are not USA approved...

they are more like 'handpump' which runs india...
still does..

batteries...
only organic/like make sense to me...

i am not for all preachy 'future' ideas..
but about 'balance' of tech..

Sun light is abundant in country like ours..
brown skin - 'indians'

primary batteries - may be 'lead and all'
but secondary - should be 'free'
or free like

in making or maintenance..

some ideas..

further thoughts...

my definition of organic - is availability - cost, origin

so salt -saltwater, sodium - baking soda and all...
they should work well

u koe that soap can make explodeys..
so it stores a huge amount of 'energy'...

aint that something?
