asteroza + boom   15

Modular spacecraft with integrated structural electrodynamic propulsion
Idea is if you have large enough structures (booms), then you can do some interesting attitude control and propulsion tricks

Efficient plasmonic emission by the quantum Cerenkov effect from hot carriers in...
Using electric driven "optic booms" to make light from electricity via plasmons. Sorta like constructive interference from sonic booms.

A photonic boom, somewhat like a sonic boom actually. Different from cherenkov radiation.

Interesting arguement that a SPS demonstrator can be built now with COTS/near COTS hardware, taking advantage of mass production of terrestrial products to reduce costs. The primary tricks being accepting losses in efficiency and overcoming it by reducing system mass, so the actual W/Kg is still higher. Thin film solar, carbon fiber booms, thin film inflatable reflectors and optics, power equipment mass reductions, and lower cost space access (SpaceX) are the COTS components that make at least the demonstrator possible. There is the interesting talk of making sure most technology/products are dual use, such as wireless power transmission to HALE LTA UAV sensor blimps to offload payload power requirements.
