CA A windmill?

WK Yeah. The windmill.

William Kamkwamba on building a windmill

Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula 23.

WK I wanted to make a windmill.

We were at the mill, near the hemp field.

Aluminium oxide is responsible for the resistance of metallic aluminium to weathering.

The principal natural isotope of aluminium is aluminium 27.

There I am like a bloody windmill again, you see.

You end up like some kind of rabid windmill.

So I decided I would build one windmill for myself.

CA And so, and that windmill, what it worked?

I'm talking about the production of aluminum.

CA And you made it out of what?

So, that's the upside. The circular mill is the downside.

CA And what did you make the windmill out of?

I had never seen a windmill until I visited the Netherlands.

Aluminium is a metal.

Aluminum is a metal.

Later years In 1825, Ørsted made a significant contribution to chemistry by producing aluminium for the first time.

I've got a hydro conversion at a watermill that I own.

The aluminum is because it's very light.

Aluminum has an atomic mass of 26.982.

It said a windmill could pump water and generate electricity.

The metaphor that I like to use is the metaphor of the circular mill.

The 1 yen coin is made out of 100 aluminum and can float on water if placed correctly.

Trace impurities of iron and aluminium are typically present.

In 1991, Alumínio was emancipated and became a city.

Inmates started making noise with their tin plates.

Magnesium is the ninth most abundant element in the universe.

Alumínio was part of São Roque city until Mairinque was emancipated as an independent city and yet, Alumínio was just a borough of Mairinque.

We cross on aluminum ladders with safety ropes attached.

Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.

Increased aluminium recycling, which has the advantage of lowering the cost in electric power in producing aluminium, will considerably extend the world's bauxite reserves.

Now, think about your interactions with aluminum foil.

It just sits in a pile near the sugar mill until eventually they burn it.

Even then each city can and often does place restrictions on sale and use.

Andalusite is an aluminium nesosilicate mineral with the chemical formula Al2SiO5.

If we put aluminum windows in this house, we would double the energy use right there.

It is also used for making aluminium hydroxide, which is used at water treatment plants to filter out impurities, as well as to improve the taste of the water.

You're looking at the cell house of a modern aluminum smelter.

All of these examples use aluminium as the reactive metal.

Aluminium is one of the most cost effective materials to recycle.
