KERI researchers develop high-capacity Li-metal battery with improved rate performance and stability

Green Car Congress

However, lithium can form dendrites if it is not uniformly and effectively stored when cycling process, leading to large volume expansion of electrode, which in turn may shorten the battery’s cycle life and cause safety issues such as fire and explosion triggered by internal short-circuits.

Ford cuts global water use 8.5% per vehicle from 2011 to 2012; total usage down 62% since 2000

Green Car Congress

Since 2000, Ford has reduced the amount of water used around the world from 64 million cubic meters to 24 million cubic meters—a reduction of about 10.6 Ford voluntarily launched its Global Water Management Initiative in 2000, putting in place ways to manage water conservation, quality and reuse of storm and process water.

Designing the First Apple Macintosh: The Engineers’ Story

Cars That Think

This article was first published as “Design case history: Apple’s Macintosh.” The author spoke with many members of the design team in the months following the 1984 introduction of the Macintosh, however, Steve Jobs did not grant an interview for this article. It appeared in the December 1984 issue of IEEE Spectrum.

Nearly 20% of intact tropical forest landscapes overlap with extractive industries

Green Car Congress

Only 20% of tropical forests can be considered “intact,” but those areas store some 40% of the above-ground carbon found in all tropical forests. Intact forests are declining rapidly, with more than 7 percent of their total area lost between 2000 and 2013. Ideally, coordination with governments will allow for landscape-scale planning.

This CAD Program Can Design New Organisms

Cars That Think

We believe that a key enabling technology in this quest is a computer-aided design (CAD) program for genome editing, which our organization is launching this week at the. Those fragments of synthesized DNA can then be sent to a foundry for assembly, and finally to a lab where the designed genomes can be tested in cells.

Who Really Invented the Thumb Drive?

Cars That Think

In 2000, at a trade fair in Germany, an obscure Singapore company called Trek 2000 unveiled a solid-state memory chip encased in plastic and attached to a Universal Serial Bus (USB) connector. Good-bye, floppy disk Before the invention of the thumb drive, computer users stored and transported their files using floppy disks.

Kopernikus Project P2X integrated container-scale test facility produces first fuels from air-captured CO2 and green power

Green Car Congress

Dittmeyer suggests that is thus only reasonable to store unused green power in chemical energy carriers. After that, a pre-industrial demonstration plant in the megawatt range, i.e. with a production capacity of 1500 to 2000 liters per day, will be designed. Four steps to fuel.
