Floating membraneless PV-electrolyzer based on buoyancy-driven product separation
Using asymmetrically catalyst coated mesh mebranes at small separation distances, vertically hanging mesh electrodes can perform electrolysis without a membrane and get good product separation, using natural gas buoyancy. Though this skews to tall rigs.

Batteries charge very quickly and retain capacity, thanks to new structure | News Bureau | University of Illinois
Interesting, using Styrofoam beads as a temporary lattice building framework to make a metal lattice, which is later covered with the final thin film. This creates a very high surface area, allowing super fast charging. But, still like SCiB batteries, it seems the energy density is lower than conventional electrode batteries of the same type (around 75%) . A worthy flaw to allow fast charging? But that doesn't get around the high amperage issues of fast charging, and there is the scary part about fast accidental discharge, so you face the same issues as ultracapacitors.
