Dear AJ The cost of electricity here in Southern Africa is based on some international cartel measure of what other batteries produce. There is no economic advantage in buying any particular size of makeup of battery. They are all about US$50 per kilowatt hour, or about one month's wages for a low-paid helper. A qualified machinist in Swaziland can afford to buy about 4kwh of battery power with a months wages. Electricity from the grid is about 3.5 cents US per kwh. Obviously there is an important hidden reason why the poor have to pay 1400 times as much for their electricity as the rich. I just haven't found it yet. The average remittance to a rural family by a migrant miner is US$30 per month so for an average Moçambique family with a foreign employed family member (which means 'rich') it is about 1.6 months total income per kilowatt of electricity produced by dry cell battery. Charging a wet cell is out of the question for most people because of a lack of facilities. I like the idea of a steam powered air injector. I have drawings...!
