My invention (by Fabi, 2d)

I'm writing about the battery.
The man who invented it was Lewis Urry, from Canada.
He got the idea when the Carbide Union asked him for the creation of a vttery with a longer duration. He experimented with some materials and he discovered that the zine had a longer duration than the common batteries. They were on sell in 1959.
Personally, I think that this invention is very useful if you use a lot of batteries.

My invention (por Lula, 2D)

The telephone was invented in 1854 by Meucci, an immigrant that didn’t have any money. The first telephone was mechanic, not an electric one like we have in our homes at the present. He invented it, because his wife was ill, she could not move, and they wanted to communicate with each other.
This invention was patented in 1871, in New York; but 10 years later he had to change the patent, but he didn´t have any money so Alexander Grahan Bell stole his idea.
