Cheap Sensors for Smarter Farmers

Cars That Think

One of the benefits of using print electronics is being able to mass-produce at a low cost, says Gregory Whiting at the University of Colorado, Boulder, one of the principal investigators of the team working on the sensors. First up is a 3D-printed, biodegradable soil sensor that checks moisture and nitrogen levels.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

I think the chemistry we have right now might be the best that’s out there for stationary storage and quite possibly cheap enough to make it in the marketplace, but we have ideas that could lead to huge improvements. —Michael J.

Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

The idea was to understand the changes in the molecular structure of molybdenum disulfide, so that it can be a better catalyst for hydrogen production: closer to platinum in efficiency, but earth-abundant and cheap. Molly is dirt cheap and abundant. Because of this, a commercial catalyst would require a huge amount of MOS 2.

UT Austin team develops new family of high-capacity anode materials: Interdigitated Eutectic Alloys

Green Car Congress

The new family of anode materials, which the researchers dubbed the Interdigitated Eutectic Alloy (IdEA) anode, also saves time and materials by producing an anode using only two simple steps instead of the multiple steps traditionally required to mass-produce lithium-ion battery anodes. —Karl Kreder.
