Somewhere he proposes that the electromagnetic field is not quantized, only the energy transfer between field and mass.

The silicon-photonic (SiPh) chip’s design is the first to bring together Benjamin Franklin Medal Laureate and H. Nedwill Ramsey Professor Nader Engheta’s pioneering research in manipulating materials at the nanoscale to perform mathematical computations using light — the fastest possible means of communication — with the SiPh platform, which uses silicon, the cheap, abundant element used to mass-produce computer chips.

The dream of wireless power transmission goes back to at least Tesla [Nikolai, not the namesake car].

The last time solar power arrays in space were promoted was back in the 1970's when many pundits were convinced that the planet would run out of oil in the 1980's.

Solar cells are about 30% efficient at best. Also they degrade rapidly over time. More so in the harsh vacuum - intense sunlight of space.

Ignoring the massive logistics issues, the key number is the conversion -> transmission -> conversion efficiency.

A link to a scientific publication, rather than a dumbed-down puff-piece from Bloomberg would be better, and more interesting.

Abstract

We propose a novel design for a lightweight, high-performance space-based solar power array combined with power beaming capability for operation in geosynchronous orbit and transmission of power to Earth. We use a modular configuration of small, repeatable unit cells, called tiles, that each individually perform power collection, conversion, and transmission. Sunlight is collected via lightweight parabolic concentrators and converted to DC electric power with high efficiency III-V photovoltaics. Several CMOS integrated circuits within each tile generates and controls the phase of multiple independently-controlled microwave sources using the DC power. These sources are coupled to multiple radiating antennas which act as elements of a large phased array to beam the RF power to Earth. The power is sent to Earth at a frequency chosen in the range of 1-10 GHz and collected with ground-based rectennas at a local intensity no larger than ambient sunlight. We achieve significantly reduced mass compared to previous designs by taking advantage of solar concentration, current CMOS integrated circuit technology, and ultralight structural elements. Of note, the resulting satellite has no movable parts once it is fully deployed and all beam steering is done electronically. Our design is safe, scalable, and able to be deployed and tested with progressively larger configurations starting with a single unit cell that could fit on a cube satellite. The design reported on here has an areal mass density of 160 g/m2 and an end-to-end efficiency of 7-14%. We believe this is a significant step forward to the realization of space-based solar power, a concept once of science fiction.

so, the mundane question is if putting and maintaining a complex array of lossy sattelite grids is cheaper and easier than batteries or terrestrial grid transmission.

i suspect the answer is obvious.
