    Whilst the scope of this idea is laudable given that the majority of battery failure occurs at the end of its useful life I feel that you will end up with a bucket full of toxic chemicals and no light whe the batteries degrade and split open destroying the lamp, (especially when used in third world situations where cheap far eastern batteries are used due to cost with no recycling facilities available).
    Capacitor driven dynamo lights are already freely available with none of the toxic recycling issues inherent to this design.

    thnks for the comment you wrote, No matter what world we live, it is the same world you live in too, the world of toxic which made by the factories in the (( first world centuries)) . Again asking about the product cost and product manufactories
