A celestial guidance system uses radio imaging of celestial bodies including the galactic plane received by an interferometric antenna array to provide robust navigation during times of cloud cover or interrupted GPS service.

An electrostatic generator adapted for high-voltage DC transmission provides a set of individual electrostatic generators connected in tandem to a mechanical input and employing floating voltage sources to allow series connection of the individual electros...

Ionic cyclic nitroxyl radical oligomers, methods of making the ionic cyclic nitroxyl radical oligomers, and electrochemical cells, such as aqueous organic redox flow batteries (AORFBs) that use the ionic nitroxyl radical oligomers as catholytes are provide...
