asteroza + impact   28

Technology | WaveCel
Interesting engineered structure to provide protection from linear and rotational impacts, as an alternative to traditional EPS foam helmets. Seems to use a slipping/buckling triangle design? I wonder what kinds of improvements there would be using a smaller microstructure?

Production of Flexible Transparent Conducting Films of Self-Fused Nanowires via ...
Launching silver nanowire suspension water out of a supersonic nozzle at a specific speed allows creating a transparent thin film mat on a surface, that fuses/evaporates on impact. The resulting thin film is transparent, conductive, and stretchable.

NASA - Sample Return Systems for Extreme Environments
Kinda similar to an "egg drop bomber" that poops out payloads at high rearward speed to reduce local ground speed before impact for hard landing stuff, but uses a mobile rotovator rather than a rearward firing gun.

A renewable energy generator for all seasons - tech - 10 June 2011 - New Scientist
Somebody had the thought of layering thin film solar PV onto those wind ribbon piezoelectric generator strips, which happen to also make electricity if being impacted by rain drops too.

Seems like they incorporated something similar to that d3o shear thickening liquid layer body armor directly into urethane foam that can be molded into protection products like sports gear and laptop covers.

Small-scale waterwheel hydropower generating buzz across Japan - The Mainichi Daily News
Considering most "rivers" and "brooks" are concrete ditches in japan, it's not that big of a deal to put in a small waterwheel for auxiliary power. I think the trick would be to design in energy storage at the waterwheel to be released during the daytime, if the water wheels are located in more rural areas. Possibly a simpler route to test early distributed grid generation capacity?
