Abstract: A portable toilet (100) comprises a reservoir (110), a reservoir cover (120) adjustably fixed on the top of the reservoir (110) and a drawer (210) inside the reservoir (110). Further, the reservoir cover (120) is having a hole (130), first cavity (140) and a second cavity (150). Further, the reservoir (110) is adapted to receive human waste from the hole (130) provided on the reservoir cover (120). Further, the drawer (210) contains a handle (220), the handle (210) is capable of moving in the first cavity (140) of the reservoir cover (120) and consequently move the drawer (210) inside the reservoir (110) from a first position to a second position. Further, the movement of the drawer (210) blocks a view of the human waste inside the reservoir (110) through the hole (130), while entering into a toilet cabin (160).

Abstract: A recycling flush toilet has a receptacle for human waste, a liquids holding tank, a base, a toilet pipe whose upper end is in fluid communication with the base of the toilet and extends downwards, a waste separation pipe extending out from the lower end of the toilet pipe, having a first end, wherein the lower end of the toilet pipe extends into the separation pipe near the first end, a filter at the lower end of the toilet pipe for separating solids and liquids, a solids container axially aligned, and in fluid communication, with the toilet pipe, and a liquids container in fluid communication with the separation pipe and adjacent to the solids container. The filter separates the waste into liquid and solid components that are disposed into the liquids and solids containers, respectively. Liquids within the liquids container are used to flush the toilet.

Abstract: A mobile oil platform has a vessel for holding oil, a subsea hose connected to a subsea well, a pump mounted on the vessel for detachably connecting to the subsea hose and one or more floats connected to the subsea hose by cables, wherein the hose is connected to the vessel, and when detached the floats hold the hose in the water. A method of hose management is described, having the steps of retrieving one or more floats connected to a hose by cables, pulling the cables from the sea to retrieve the hose, and connecting the hose to a platform. The hose may be disconnected and dropped in the water wherein a float marks a hose position. Further, probes may be deployed to suck the oil/water mixture into a separator.

Abstract: An oil spill cleanup system has a vessel, a separator within the vessel for separating oil and water, a pump for pumping an oil/water mixture into the separator, and one or more probes and submersibles having hoses connected to the pump, for collecting the oil/water mixture. The separator has two or more adjacent tanks, for containing the oil/water mixture. Gravity separates the oil from water in the first tank and the water is evacuated from the bottom, while the oil overflows in the second tank, having an increased oil concentration, and so on, until the pure oil is evacuated. A mobile oil platform is also disclosed, having a subsea well connected to a hose, the hose carrying oil to a vessel, wherein the vessel receives the oil and is exchangeable with an empty vessel when full. When the vessel drops the hose, floats maintain the location thereof.

Abstract: A mobile oil platform has a vessel for holding oil a subsea hose having an open end configured to engage with the platform, and an opposite end connected to a subsea well, a pump mounted on the vessel configured to detachably connect to the subsea hose to pump oil into the vessel, one or more floats connected to the subsea hose by a cable configured to hold the end of the subsea hose, wherein the subsea hose is detachably connected to the vessel and when full, the vessel detaches the subsea hose such that the floats hold the subsea hose in the sea, and the full vessel is replaced by an empty vessel, and wherein the platform comprises a plurality of interconnected barges to make possible a floating station for oil production in deep sea and an emergency floating sea port for remote areas.
