Is this similar to Quorn and that russian methane bioreactor system for making protein? The green part is a bit of a red herring in that they simply use electrolysis to produce the hydrogen needed for the bioreactor, along with the nutrient mix and CO2. The russian bioreactor setup I believe used electricity directly plus methane.

Amelioration of Diabetes in a Murine Model upon Transplantation of Pancreatic β-Cells with Optogenetic Control of Cyclic Adenosine Monophosphate | ACS Synthetic Biology
Huh, modified beta cells produce insulin only in the presence of high glucose levels and blue light, so the current glucose level acts as an activation floor to prevent insulin overproduction as a failsafe.

Using a Retroshare F2F P2P network, this sets up in essence a distributed network of protest cells, useful for rapidly propagating information in a semi-directed protest. This is being actively used in 2019 protests in Barcelona. The app isn't 100% open source though, so what level of visibility/control the creator has is unknown.

Identification of the mechanism responsible for the boron oxygen light induced degradation in silicon photovoltaic cells: Journal of Applied Physics: Vol 125, No 18
PV solar cell degradation actually has a previously unseen mechanism, which has now been identified. It appears the solution to "repair" degraded solar panels (increase effective lifetime) is to heat them in the dark for a few minutes at 200C, but that only resets the lifetime and doesn't prevent degradation? Unfortunately, wire solder melts at below 200C, so you can't just bake an old panel in your home oven to fix it or the interconnects will dribble out.

Insolight – Making solar energy affordable
Smart idea, using microlens plastic plate over CPV solar cells in a grid pattern under the plate, then shift the plate a little bit to track the sun. So basically you could do an artificial muscle actuator or MEMS to shift the plate, rather than some gigantic tracking heliograph CPV setup. Plate shift still limits tracking angles, but the cost is much cheaper.

Freezer using high powered magnets to vibrate water in cells which are supercooled, keeping them liquid. Drop the magnetic field, and the water flash freezes with low crystallization, reducing damage to cells. Good for stem cell freezing, and also makes frozen food taste less mushy because the cells aren't destroyed.

Stacking a PV layer on top of a pyroelectric layer stacked on a thermoelectric layer means light not captured by the PV layer gets turned into heat/power by the pyroelectric layer, and the resulting thermal difference with ambient is utilized by the thermoelectric layer. Claimng +20%.

CLOSING THE CARBON CYCLE: sunfire GmbH
Apparently they have a good high temperature steam electrolysis SOEC that can produce hydrogen at decent efficiencies, for feeding into a RWGS conversion reactor syngas production rig, to eventually produce synthetic methane (combining syngas from the reactor with additional H2 from the SOEC), or eventually via FT, synthetic liquid fuels. They don't seem to be doing a coelectrolysis SOEC to crack steam and CO2 simultaneously in the same cell stack though.
