A solid dispersion redox flow battery is a type of redox flow battery using dispersed solid active materials as the energy storage media. The solid suspensions are stored in energy storage tanks and pumped through electrochemical cells while charging or discharging.
Diagram of the divided zinc–cerium redox flow battery. Zinc–cerium batteries are a type of redox flow battery first developed by Plurion Inc. (UK) during the 2000s. [1] [2] In this rechargeable battery, both negative zinc and positive cerium electrolytes are circulated though an electrochemical flow reactor during the operation and stored in two separated reservoirs.
Batteries are used on spacecraft as a means of power storage. Primary batteries contain all their usable energy when assembled and can only be discharged. Secondary batteries can be recharged from some other energy source, such as solar panels or radioisotope-based power (), and can deliver power during periods when the space vehicle is out of direct sunlight.
RQ-20A Puma Military designation for the Puma All Environment variant. Enhanced Puma Upgrade of the RQ-20A Puma AE with more powerful propulsion system and new batteries that increase endurance by 75 percent to 3.5 hours, auxiliary payload bay to integrate payloads while keeping the video camera, precision navigation system with secondary GPS, and a redesigned durable fuselage with reinforced ...
The rise of air power meant static ground defences like Battery Kingman were vulnerable to air attack. Batteries Kingman and Mills were modernized to meet this threat and their guns were protected from aerial bombing by the addition of thick concrete walls and roofs making it a casemate or fortified gun emplacement or armored structure from which guns are fired.

An aerial tramway consists of one or two fixed cables (called track cables), one loop of cable (called a haulage rope), and one or two passenger or cargo cabins.The fixed cables provide support for the cabins while the haulage rope, by means of a grip, is solidly connected to the truck (the wheel set that rolls on the track cables).
Bell created the V-247 to meet emerging U.S. military needs for a runway-independent Group 4 or 5 UAV to provide persistent support to ground forces while requiring less space to store and transport; Group 4 UAVs weigh more than 1,320 lb (600 kg) and fly below 18,000 ft (5,500 m), while Group 5 UAVs weigh the same but fly above 18,000 ft, such as the MQ-9 Reaper, RQ-4 Global Hawk, and MQ-4C ...
Electron is a two-stage, partially reusable orbital launch vehicle developed by Rocket Lab, an American aerospace company with a wholly owned New Zealand subsidiary. [14] [15] Servicing the commercial small satellite launch market, [16] it is the third most launched small-lift launch vehicle in history.
