is pursuing an electrical engineering degree at the University of Scranton , in Pennsylvania. The junior is president of the university’s W3USR amateur radio club. Piccini now is helping to develop a low-cost, low-power system to send a signal into the ionosphere and measure the time it takes to return.

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

Green Car Congress

A team led by researchers from Sandia National Laboratories has shown that molybdenum disulfide (MoS 2 ), exfoliated with lithiation intercalation to change its physical structure, performs as well as the best state-of-the-art catalysts for the hydrogen evolution reaction (HER) but at a significantly lower cost.

Or, that was the idea, anyway. KAIST/Korea Polytechnic University The paper doesn't directly address the cost of the MHD, and with three motors and some other electronics in it, it's not likely to be super cheap. I'd expect it to cost at least USD $100, although perhaps it could get somewhat cheaper in volume.

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

Green Car Congress

Researchers in the Cockrell School of Engineering at The University of Texas at Austin have developed a new family of anode materials that can double the charge capacity of lithium-ion battery anodes. It is a simple, low-cost approach that can be applied to a broad range of alloy systems with various working ions such as Li, Na, or Mg.

Stanford researchers develop new electrolysis system to split seawater into hydrogen and oxygen

Green Car Congress

Hongjie Dai and his research lab at Stanford University have developed a prototype that can generate hydrogen fuel from seawater. Developing cheap electrocatalysts and electrodes that can sustain seawater splitting without chloride corrosion could address the water scarcity issue. Image credit: Courtesy of H. —Hongjie Dai.

Their journey began with a question posed by its founders, Tommi Eronen and Markku Ylönen, when they were university classmates: “Is it possible to build an energy-self-sufficient and cost-effective hippie commune for engineers using only solar power?” Sand is efficient, nontoxic, portable, and cheap!”. “We
