Ships are built in shipyards, most often on dry docks that are slightly sloping towards the water surface. On such docks, there are rails on which the ship is built, and after the completion of constr...
There are various types of seawater desalination devices for drinking water and plant irrigation. Most of these devices use a lot of energy to evaporate water and convert it into water vapor which is...
At the bottom of the sea, various works are often performed by divers. Some such works can be done much more easily when a dome is placed at the bottom of the sea under which air is blown. Then worker...
In recent years, many authoring teams have been encouraged by grand prizes, mostly in the US with made cars that can take off vertically and fly at shorter distances. Flying machines can be divided in...
Chains for cars used for driving on snow can be purchased in stores. It’s a little harder to get auxiliary tools for driving over deep mud, which often happens when off-road cars drive through a fores...
One-wheeled trolleys, the wheelbarrow, are a small innovation that has significantly facilitated work in construction, but also in agriculture. These carts allowed one man to easily carry a load great...
The vast majority of ships will sink if they are overturned by the waves, or if an opening is formed in the hull of the ship through which water suddenly enters. Some sailboats have ballast that retur...
