Using self interference tricks to cancel out noise to effectively create a single carrier full duplex radio. There was a SatCom company (ComTech called it Carrier-in-Carrier) doing this in in L-band, but this company wants to do it in LTE/ISM bands, which requires 5 orders of magnitude more cancelling signal.

Siemens AG - Efficiency Record of Combined Cycle Power Plant
Interesting fully integrated generation single shaft train CCGT. That's one hell of an ugly shaft optimization problem, since you have fairly high speeds in a gas turbine, but that isn't necessarily the case with a steam turbine, and then you have the ideal RPM of the generator itself (typically 5000 or 6000). If it truly is single shaft with no transmission gearing (only clutches), that makes it even harder. There is the possibility that the GT and ST share the same transmission to shift mechanical torque to the generator shaft speed, but that doesn't seem to be the case here.

Single-Step Extraction | OriginOil - Breakthrough Algae Oil Technology
Interesting take on the algae lipid recovery process, similar to GM algae that excrete oil, since both processes use a tank with surface skimming for recovery. Basically a wet recovery process that skips the drying process of conventional biomass lipid recovery. Still kills the little guys, but you would end up doing that if biomass was a production target anyways, but that introduces the issues of whether or not the energy costs of drying are transferred to the biomass or should be charged to the lipids, and there is a secondary concern of what sort of changes occur in the biomass, that could potentially make it unattractive as a product for specific industries (maybe pharmaceuticals/nutriceuticals might be out, but straight animal feed and biomass feedstock should be alright)
