Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

The researchers believe this new type of photoelectrode is not only cheap to produce, but can also be recreated on a larger scale for mass and worldwide use. The LaFeO 3 working electrode and Pt counter electrode were connected by a single looped wire, without any external bias being applied. —Pawar and Tahir. Govinder S.

A DIY E-bike Conversion on the Cheap

Cars That Think

The handlebar-mounted controls connect with an Arduino, which interprets their settings and translates them into a PPM signal, which is applied to the electronic speed controller. The speed controller is connected to the motor and battery in the usual fashion, with an automotive-type blade fuse in line for safety. OK boomer," indeed.

OSU hybrid “solar battery” uses photo-assisted charging to improve performance of Li-air batteries; “negative overpotential”

Green Car Congress

On charging, the photoelectrode and Li anode are connected to the outside circuit; on discharging, the oxygen electrode and Li anode are connected to the outside circuit. (b) Normally, connecting a solar cell to a battery would require the use of four electrodes, the researchers noted. Their hybrid design uses only three.

KTH team develops new cost-effective water-splitting electrocatalyst for H2 production

Green Car Congress

The new catalyst also offers a competitive, cheap alternative to catalysts that rely on more expensive, precious materials, such as iridium oxide (IrO 2 ) or ruthenium oxide (RuO 2 ). The material possesses a layered structure with monolayer nickel-vanadium oxygen polyhedron connected together with a thickness below 1 nanometer.

These modules are cheap—they can generally be found for around US $25. I soon settled on a configuration consisting of two printed circuit boards connected by ribbon cable. Together, we completely reviewed the code and added a smoother graphical design, more connectivity, selectable languages, and other improvements.
