Cristiano and me had the possibility to visit Aloise house in Ilembula. He was happy to show us his house he built by himself.

It was nice, simple and clean. He has a stable work as foreman in the Catholic Parish, so his family and him live probably better than other neighborhoods.

According to him he has an agreement with the priest (Father Tarcisio Moreschi): beside his salary he can recharge an old truck battery in the garage, using the parish electricity, every time he needs.

Tanesco is the electricity provider all over the country, but the grid is really bad, the electricity is expensive, and the grid covers only a few areas, especially bigger towns and cities.

So having an off-grid system to produce electricity can be a great choice.

But...how much electricity does a common family need, over there?

We had the possibility to ask Aloise how much he consume, day by day:

• 2 led strips, 5W + 5W, 5hours per day
• television, 33W, 3/4 hours per day

Nothing else.

More or less something like 180Wh per day, or 15Ah@12V, or 7.5Ah@24V (since the battery he uses comes from an old truck). Not so much, no surprise thinking Aloise told us the battery lasts up to a month if used only with leds, or 3/4 days if using TV.

The battery, clearly, is not the one he should use for such service. But this is it.

Wind blows hard over his roofs for 6 hours a day, during the night, usually: good!
It could be possible to recharge over night and use power along the day. Nice!

I will show you a simple wind turbine able to outcome 20Watt@5m/s wind would be enough, with, ok, a better battery and a specific charger.

I'm going to build this.

Following the original papers, with numbers and money needed, I took at Aloise home
