The initial Global Power Plant Database, an open source database of the power plants globally, was released in April 2018. [55] As of May 2021, the portal itself is still under development. Power Explorer is also supported by Google with various research partners, including KTH, Global Energy Observatory, Enipedia, and OPSD.
Solar Dynamic (SD) power systems concentrate sunlight into a receiver where the energy is transferred to a heat engine for conversion to electrical power. Brayton heat engines utilize a turbine, compressor, and rotary alternator to produce power using an inert gas working fluid. Such a system was devised for use on an SSP. [citation needed]
The Energy Efficient Engine was a program funded by NASA in the 1970s to develop technologies suitable for energy efficient turbofans. Its goal was to improve thrust specific fuel consumption by 12% compared to a GE CF6-50C. [1] Both General Electric and Pratt & Whitney produced turbofans for the program.

Artistic view of Deep Space 1, showing both the solar panels and ion engine (with blue exhaust), major aspects of this solar electric design. Solar energy may also be temporarily stored in chemical batteries inside the spacecraft bus. The Dawn spacecraft's xenon tank prior to integration with spacecraft. The xenon was the propellant for the ...
The search engine first filters search terms in several ways. An M followed by a space or hyphen has the space or hyphen removed, so that searching for Messier catalogue objects is simplified and a user input of M45, M 45 or M-45 all result in the same query being executed; similarly, NGC designations and common search terms such as Shoemaker ...

A view from inside the vacuum chamber showing the Advanced Electric Propulsion System fired up during qualification testing at NASA Glenn. In July 2017, AEPS was tested at Glenn Research Center. [12] The tests used a Power Processing Unit (PPU), which could also be used for other advanced spacecraft propulsion technology. [12]
