Octopus-Inspired Smart Adhesive Pads for Transfer Printing of Semiconducting Nan...
Interesting material, where heating it causes micropore suction cups to open up so it sticks when slapped onto something, but the pores close when cold. Reusable glue of a sorts?

IEEE Xplore - Ocean Renewable Energy Storage (ORES) System: Analysis of an Undersea Energy Storage Concept
Hollow concrete sphere anchors for floating wind turbines do double duty, anchor the turbine, and serving as an energy storage subsystem by pumping water out of the sphere at depth. 30m sphere stores roughly 6MWhr, sweet spot is 750m depth, economically viable at 400m, works at 200m in a pinch, 1500m is pushing it (stress fracture implosion of the vapor head inside would be fierce).

I wouldn't have expect a side suction slot that ends up reversing the flow completely before it reaches the fan (360 degree flow path change) would have improved things.
