Since its first expedition to the Titanic shipwreck in the summer of 2021, the Titan’s crews encountered problems aboard the submersible, including issues with its electrical system and battery ...
A few underwater lights have a focusing facility by which the beam angle can be adjusted. There are two ways this can be done, depending on the basic emission pattern of the light source. HID lights, which generally produce non-directional light, are usually focused by a reflector, which can be slid longitudinally over the light.
A windpump replaced by a solar-powered pump at a water hole in the Augrabies Falls National Park. [Notes 1] This solar water pump up to 3.7 kW is useful for farmers.Solar-powered pumps run on electricity generated by photovoltaic (PV) panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity- or diesel-run water pumps.

The batteries were of a new design. Compared with the original Sargo battery, the Guppy battery used a greater number of thinner plates that would generate higher current for a longer time. However, these batteries had a shorter life, 18 months versus the five years of the Sargo battery, and took longer to charge. They also required ventilation ...
Alternating-current (AC) submarine cable systems for transmitting lower amounts of three-phase electric power can be constructed with three-core cables in which all three insulated conductors are placed into a single underwater cable. Most offshore-to-shore wind-farm cables are constructed this way.
A 0.75 HP bore-well submersible pump which had been used to pump groundwater One style of submersible pump for industrial use. Outlet pipe and electrical cable not connected. A submersible pump (or electric submersible pump (ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in ...
