This invention concept pertains to a cargo ship, that transports cargo, such as freight, or cargo truck trailers, or cargo truck containers. This concept for a cargo ship is entirely environmentally friendly.
Water Pump Redundancy System
There could be offline backup water pumps, in a storage room, in addition to other key replacement components, as well as a set of standby backup water pumps, as well, that can come online if the main water pump(s) are being serviced. All of the water pumps could be separate, so there could be two main water pumps, and two backup water pumps, however any of the four water pumps can be used, and the backup and main water pumps are interchangeable, so as all the water pumps get an equal amount of wear and tear, over time, or they are operated for predictable obsolescence and replacement strategies.
Water Filtration Technology
There is a water pump and filtration system, that screens out large debris from a large suction porthole using a water debris screen, underneath the water. There are water pumps, that pump in sea water into a reverse osmosis filtration system, without the debris ever entering the porthole or pump or filtration system.
The reverse osmosis filtration system (ROFS) is just a pre-filtration system, that removes brine, including chemical substances, including arsenic, calcium carbonate, chlorine, forever chemicals (PFAS), lead, rust, and sea salt, as well as biological species, including bacteria, viruses, and volatile organic compounds (VOCs). The supply of filtered water from the reverse osmosis filtration system, shall herein be referred to (“permeate”).
The dirty water on the pressurized side of each membrane, that is eventually removed as part of the brine, shall herein be referred to as (“solute”). The cleaned water that has passed through each membrane, that has passed on to the other side, shall herein be referred to as (“solvent”).
There are several filter levels of the ROFS, including sediment filters of different pore sizes, which traps and removes particles, including calcium carbonate, lead, rust, and sea salt. There are also activated carbon filters, to trap and remove organic compounds, including volatile organic compounds (VOCs), in addition to chlorine, removed with the brine, which is no longer in the solvent when the water has passed through this filter membrane. There is also a thin-film reverse-osmosis (RO) composite membrane, that further filters the solvent from the previous filters, into a much cleaner solute. There is also an ultraviolet light (UV) that sterilizes microbes, including bacteria and viruses, from the solvent, into the cleaned solute. There is also a second set of activated carbon filters, that further capture and remove chemical compounds that survived the reverse-osmosis (RO) process. There are even more types of smaller pore membranes, including to conduct systematic processes that pressurize and filter the water, that screen out and remove everything that is not pure filtered water (H2O), including using a reverse-osmosis electrolysis system (ROES), that separates the water (H2O) into Hydrogen (H) and Oxygen (O2), into huge tanks in the middle of the cargo ship.
There are even port holes on the top of the natural gas tanks (H2, O2), that a ladder can go into, and service the tanks, including when out at sea, if necessary.
Main Engine Technology
Either or both the Oxygen (O2) and/or the Hydrogen (H2) gas(es) can be used to power a noble gas combustion engine, that has between 12 to 16 giant pistons, that cycle up and down, managed by a crank shaft, that is connected to a drive shaft with transmission gears, that control the speed and agility of the drive shaft, with respect to how the noble gas combustion engine is operating, currently.
Hydrogen (H2) Fuel Cell Technology
There is also a way to use the Hydrogen (H2) natural gas, to pull in more Oxygen (O2) naturally abundant gas, from the air atmosphere, by using a hydrogen electric fuel cell, to use this process to convert the excess electrical activity, in the proton-exchange membrane (PEM), to direct current (DC) to charge a large electrical room full of solid-state lithium-ion batteries, to store electricity, with only a byproduct of water (H2O) from the Hydrogen (H2) fuel cell.
Electrolysis Technology
The water can continually be cycled through a process of electrolysis, using the batteries to convert the water to Hydrogen (H2) and Oxygen (O2), again, to provide Oxygen (O2), only, to provide a fuel to power the main engine, to get it to a dry dock, such as in case the water pump was broken.
Electrical Generator Technology
There is also an direct current electrical generator on the drive shaft that emanates from the noble gas combustion engine. The drive shaft is also used to turn the propellers.
The lower power of the engine could be used, such as with a split crank shaft, and a split drive shaft, to just power the generator. This power could be used to just charge the batteries, even more so, and additionally, to power smaller electric propellers that are underneath the cargo ship, or at least until a mechanic can replace the water pump.
