Enhancing Mechanical Properties of Pervious Concrete Using Carbon Fiber Composite Reinforcement | Journal of Materials in Civil Engineering | Vol 30, No 3
permeable concrete normally sucks, but throwing ground up waste carbon fiber into it makes it strong enough for actual usage, particularly for road/ground cover where you want rain water to pass though into the ground reasonably quickly, rather than collecting pollution then ending up in storm sewers..

[1504.06751] Silk reinforced with graphene or carbon nanotubes spun by spiders
Uh, so having spiders swim in graphene/nanotube laced water makes them produce super silk. This may not end well...

UA Engineering Professor Uses Aerospace Materials to Build Endless Green Pipeline
Hrm, manufacturing method is actually EXTREMELY similar to Lockheed's OTEC CWP continuous pipe maker technology. The difference may be Lockheed's pipe maker uses a laminate fabric laydown process that follows the pipe axis, while this seems to do a possibly continuous spiral wrap. Hard to tell.

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.
