This paper considers the conditions, opportunities and constraints under which beamed power might be attractive for space-based enterprises. First, an evolutionary, revenue-generating architecture for beaming electric power through space to terrestrial and space-based customers is presented, to understand the likely environment where full-scale Space Solar(More)
Pressure-sensitive paint is presented and evaluated in this article as a quantitative technique for measurement of acoustic pressure fluctuations. This work is the culmination of advances in paint technology which enable unsteady measurements of fluctuations over 10 kHz at pressure levels as low as 125 dB. Pressure-sensitive paint may be thought of as a(More)
The Space Power Grid architecture jump-starts the move towards Space Solar Power (SSP) by setting up a power exchange between terrestrial power plants and customers through Space. A constellation of low-mass, low-risk waveguide satellites starts the first phase. With technical and policy issues settled and the market risk reduced, expansion to full SSP is(More)
This is an update of the Space Power Grid architecture for space-based solar power with an improved design of the collector/converter link, the primary heater and the radiator of the active thermal control system. The Space Power Grid offers an evolutionary approach towards TeraWatt-level Space-based solar power. The use of millimeter wave frequencies(More)
This paper lays out an approach to develop Space Solar Power, with a small initial investment, a rising market, early revenue generation, and an evolutionary path to full Space-based power generation. The key idea is to use space assets initially for a global power exchange, establish the infrastructure, and then add space-based power as technology advances(More)
The Space Power Grid (SPG) architecture described in papers from our group since 2006, is an evolutionary approach to realizing the global dream of Space Solar Power (SSP). SPG first concentrates on helping terrestrial power plants become viable, aligning with public policy priorities. It enables a real-time power exchange through Space to help locate new(More)
Retail delivery of electric power through millimeter waves is relevant in developing areas where the market for micro devices outpaces the power grid infrastructure. It is also a critical component of an evolutionary path towards terrestrial and space-based renewable power generation. Narrow-band power can be delivered as focused beams to receivers near(More)
A central element in the use of Space as a power grid for near-real-time power exchange, is a constellation of satellites, capable of receiving and relaying beamed power at multi-megawatt level with extremely high efficiency and low thermal losses. The conceptual design of such a satellite is considered in this paper. Preliminary calculations indicate that(More)
