MIT Looks Ahead to Hydrogen’s Aviation Future

Cars That Think

As investment in hydrogen-powered flight expands , airports and air carriers today are realizing that it’s not enough to retrofit or design new planes for hydrogen power. John Hansman , an aeronautics and astronautics professor at MIT and director of the university’s International Center for Air Transportation. asks Professor R.

Novel Li-metal electrode design could lead to more powerful solid-state batteries

Green Car Congress

Researchers at MIT and their colleagues are proposing a new design for electrodes that, based on the long-sought goal of using pure lithium metal as the anode, could lead to longer-lived batteries with higher energy densities. We designed this structure that gives us three-dimensional electrodes, like a honeycomb. —Ju Li.

MIT: hybrid cathodes could boost energy capacity of lithium-sulfur batteries

Green Car Congress

Researchers at MIT and in China are proposing a new class of dense intercalation-conversion hybrid cathodes by combining intercalation-type Mo 6 S 8 with conversion-type sulfur (HMSC) to realize a Li–S full cell. Design strategy for jointly high gravimetric–volumetric energy density. 1 and a volumetric energy density of 581?Wh?l

MIT study: people globally follow a “visitation law”; inverse relationship between distance and frequency of visits

Green Car Congress

A new paper by an MIT team and colleagues in Singapore, China, Italy and Denmark, drawing on global data, finds that people visit places more frequently when they have to travel shorter distances to get there. —Paolo Santi, a research scientist at the Senseable City Lab at MIT and co-author. Schläpfer, M., O’Keeffe, K.

Algorithm Uses Evolution To Design Robots

Cars That Think

To accomplish tasks, they need both a well-designed body and a “brain,” or controller. But there are few ways to optimize a robot’s design at the same time. Unless the designer is an algorithm. They presented the system at this year’s Conference on Neural Information Processing Systems. The same is true for robots.

How MIT’s Muriel Medard Pioneered the Universal Decoder

Cars That Think

The MIT electrical engineering and computer science professor’s positive thinking has led to new ways to improve tried-and-true techniques in the field of information theory. The chip uses a new algorithm the team developed with Ken Duffy from Maynooth University : guessing random additive noise decoding (GRAND).

ARPA-E awarding $10M to 8 projects studying low-energy nuclear reactions

Green Car Congress

Amphionic proposes to optimize cathode design to form Pd-polymeric composites within which the Pd nanoparticle size and shape are varied, and the interfacial separation and geometry are controlled. Stanford University. Stanford University will explore a technical solution based on LENR-active nanoparticles and gaseous deuterium.
