OSA | Monolithic ultra-high-Q lithium niobate microring resonator
so lithium niobate makes for great resonators for fiber optic networks, but is chemically inert so you can't etch it easily. Now, it looks like they've achieved usable dry plasma etching to make waveguides/resonators.

Interesting dry erase notebook, internally filled with thin flexible whiteboard pages (6 or so pages?) and intermediary clear pages to protect the whiteboard pages from smudging against each other.

Wow, microfluidic channels embedded in fabric which allow directional control of fluid movement, so you can do things like channel sweat from a shirt into the shirt bottom so it will drip out.

Apparently a "dry" fracking technique using no water, just gelled propane (WTF?!?). Interesting methodology...

GE Combines Natural Gas, Wind, and Solar - Technology Review
So the idea is colocate a wind turbine array in the solar thermal heliostat field, and use the solar thermal heat to boost the steam turbine in a natural gas combined cycle rig. No mention of thermal heat storage from the solar thermal system, but considering the gas turbine can operate in peaking mode, there's less of an incentive to do so. The gas turbine also can do some load following moves to buffer the wind turbine output to take care of the wind power variability issue. It appears to spec for dry cooling the steam turbine. The core concept of a heavily integrated multisource powerplant is intriguing, and does cut the cost of some equipment (mainly steam turbines/generators, and transformers, and controls). However, if the integration is too high, then later expansions or uprates will unbalance the optimizations, potentially to the point that it may not be worth the costs.
