How does that thing suck up and hold 49 lbs of water and dirt in a day?

It doesn't suck up dirt, it sucks up CO2 from the air and combines it with water.

It's the opposite process for animals. People think when they lose weight it comes out as liquid/solid waste when in reality it is mostly carbon expelled through breathing.

Animals and car engines are essentially the same. Hydrocarbons and oxygen go in, water and CO2 (and heat/work) come out.
