    The act of searching, purchasing and tending to a wood and dung based cook
    stove needs to be the thing of the past. Who can give insight to me on the
    reality of things on the ground, out in the world as you see it. I need this feed back
    for my main project A Spring Wound Battery. Thank you very much.
    Students answers are my main interest.

    The reality is that in the area of Tamilnadu ( a Southern State of India) one in six among the poorer people is orthopedically handicapped because of falls sustained when climbing trees with dried branches hunting for wood for fuel. Something like 9 million women die yearly from carbon monoxide poisoning in one room huts from country stoves burning poorly dried wood. Many children of these also suffer damage.

    You should see the works of Prof.Kirk Smith, Professor of Global Environmental Health, School of Public Health, University of California, Berkley and Tyler Laureate 2012 on indoor pollution.

    However, the energy levels have to be considered. An adult human consuming 2400 kcals nutrition can at best put out 100 watts. Basal Metabolic Rate will consume some of this for survival. Usable output cannot be much above 60 to 70 watts. Even this is not sustainable for more than an hour or so by most ordinary people, certainly by poorly fed women in the Third World. Even if all of this can be recovered as electric power no useful cooking is possible.

    That is good information. But my intention is not to use human power to recharge the unit. You see I know the the electrical distribution and accountability of it's usage is not accurately done, over charging many unfairly. So my intent is to be able to have the unit recharged at a government, or NGO station. Hopefully a subsidized recharging stations so that cheap electrical power is obtainable to those that really need it. Obviously this is not for every person and application. But of the 500 million people in that position world wide ei. Africa, India, Asia, if I touch one percent I am a success. Is a cheap electric stove top affordable to them? I have been pursuing this for a while and it seems as though the eliete write all these papers on things but don't do anything about it. I am building it now with out their help. But i need yours to see reality. Thanks

    A V My Indian customers tell me of their villages where everyone drinks from a town well. Why can't their be a wind turbine that can be utilized to recharge the spring wound battery either mechanically or electrically. He tells me that the men don't work hard. So I figure they can carry the batteries to and from the elderlies homes as a curtsey. I remember the first time the sewerage backed up in the restaurant and I was on my hands and knees vacuuming it up and the owners were aghast. Now they are my closest friends and as a matter of fact I am going to dinner tomorrow night with Prasad.

    AV You are a very smart man and I value your input. Please keep in touch. I need you.

    Induction heating is the best option. It is nearly 95% efficient. Almost all low end SS cookware sold in India is induction compatible. TTK Prestige Limited in India is working on a no-frills, low cost, low power (<1000W) induction cooker just for this application.
