ISLANDS and AREAS of LIGHT – Infrastructure Development

Subject: Electricity – HFAC power distribution









The Areas of Light – a larger Island of Light – from a technical infrastructure point of view...

NASA's power distribution system, of 440V, 20kHz, with a power rating of hundreds of kW,  a neated path for our Areas of Light (larger than Islands of Light) infrastructure development.











Proposed HFAC power distribution for Areas of Light infrastructure
