Hydrogen is very light material. Oxygen can be found in rocks. If you are equiped with hydrogen cyllinder and have an energy origine (e.g. solar)
to produce oxygen from rocks - combining them will make water

They need food which is glucose and they need water and light to photosynthesise.
The inventions and innovations of the mid-19th century helped fuel both the economies of the North and South. The manufacturing centers of the North could produce more textiles more easily and efficiently with the technologies while the plantations of the South could produce more cotton with agricultural innovations. Inventions such as the steam engine improved shipping of goods by land and sea.
