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.

Minimally Invasive “Stentrode” Shows Potential as Neural Interface for Brain
> Whereas traditional electrode arrays are implanted into the brain through a surgical procedure that requires opening the skull, the stentrode is delivered via catheter angiography, a much lower-risk procedure. The catheter is inserted into a blood vessel in the neck. Researchers then use real-time imaging to guide the stentrode to a precise location in the brain, where the stentrode then expands and attaches to the walls of the blood vessel to read the activity of nearby neurons. The stentrode technology leverages well-established techniques from the field of endovascular surgery, which uses blood vessels as portals for accessing deep structures while greatly reducing trauma associated with open surgery. Endovascular techniques are routinely used for surgical repair of damaged blood vessels and for installation of devices such as stents and stimulation electrodes for cardiac pacemakers.
