What is the availability & cost of the iron sulphate?

That's a good point. It seems to me that a better solution would be either using solar panels (where sunlight is available) or maybe a Sterling engine powering a generator (where anything can be burned to produce heat).

The important thing is not depending on consumables which may not be easily obtainable.

So, in a place that has access to cellular phones, cellular service, and LED bulbs, you are seriously concerned that they won't be able to obtain the expendables? I'm quite sure this is a little bit unfounded. I'd much rather rely on a $12.00 system with 10-cent-per-day expendables than anything solar. Not to mention the documented environmental impact of the production of solar panels, plus the additional E-O-L impact. Give me the chem-reaction system ANY day [or night].

First world solutions rarely solve third world problems historically.

There is no battery that GENERATES POWER as the title says . All batteries are just store houses of energy and release it, as needed . Any batteries need to be charged from a source of power .

No, that's either a capacitor or a rechargeable battery or 'accumulator' in old-speak.

A battery or cell is a device that converts chemical energy to electrical energy. Theoretically, the process is reversible, but most older battery technologies make that impracticable. Lead-acid and nickel-iron alkali (are you old enough to remember that?) were exceptions until NiCd began a slow revolution. The modern rechargeable lithium cells are only made practicable by fancy electronics which keeps their charge-discharge parameters within very strict limits.

This battery appears to use ferric sulphate to oxidise iron to generate electricity. the ferrous sulphate that results could then be re-oxidised to ferric sulphate by air, but there would still have to be a supply of acid sulphate for that to work, and the iron would still be consumed, so I think this is still probably a one-way process.

Could this small battery be made considerably bigger in order to be used for cooling, heating, cooking, running a dish washer etc? Could it be used for accumulating solar energy? Would this be economically feasible?
