A trip around the residential houses in the area of Los Angeles
That's what happened a day of fun, I passed settlements, and something caught my eye, a nod pump (sucker rod pump) which serves as a tool to raise the oil to the surface of the ground.
The story of the petroleum is always interesting, this equipment has been used in the US since World War II as a means of lifting the liquid.
Despite oil prices are down, it's time to stop drained earth, and towards the more advanced fuels.
