Interesting use of a linear piston motion of a wave power buoy to drive a mechanically driven high pressure seawater pump for a reverse osmosis water desalination rig. RO requires high pressure, which typically requires a lot of electric power for a electric pump, but by using gradual pressure building using a wave driven seawater pump, you can achieve equivalent pressures. Potentially convenient for small island resorts that have very little electrical power. But the long water pipe is a bit of a problem. If it were me, I would use the wave buoy to send pressurized seawaater directly via pipe to a beach building with the RO rig and a pressure accumulator tank, since that keeps the more finicky parts out of the water.

Apparently Toucan birds have a highly mechanically optimized beak. Very lightweight, with a hollow structure where there are no stresses, and elsewhere a bone fiber/membrane foam enclosed by an outer keratin tile sheet exterior, creating a natural biocomposite foam sandwich material in their beaks. Still doesn't explain fully why the beaks are so large, especially for a fruit eater. There was other research into beak properties by using IR camera studies, and it appears the beak is also used as a high performance controllable blood heat radiator to dump metabolic heat. They do interesting tricks like doing a burst of heat dumping just prior to going to sleep to slow down metabolic processes quicker.

Company touting "net negative carbon" fuel manufacture. I would call it more like net neutral. Sounds like they are making biochar while capturing syngas, just with a better gasifier and preprocessor. Might be interesting though.

Weird joint/gymbal design that gets around the need for slip rings in traditional rotating joints if you can tolerate flexing conduit/pipe/tube in your design (or if you are clever, route through only single degree of freedom hinges), and neatly gets around the 90 degree problem that prevents the use of CV joints.
