the government’s green energy incubator fights for survival in the age of trump




this week, arpa-e is showing off far-out ways to cool, heat, convert, conserve, and invent energy—all of which could be on the chopping block. the post the government's green energy incubator fights for survival in the age of trump appeared first on wired.



theoretical battle: dark energy vs. modified gravity




expansion driven by dark energy is now overwhelming the effect of gravity.photograph by copyright nobel mediashare this storytwo decades ago, scientists found that the universe’s expansion is accelerating. this was the complete opposite of what had been expected: the expansion should be slowing do...



nano-sized hydrogen storage system increases efficiency




lawrence livermore scientists have collaborated with an interdisciplinary team of researchers including colleagues from sandia national laboratories to develop an efficient hydrogen storage system that could be a boon for hydrogen powered vehicles. hydrogen is an excellent energy carrier, but the de...

nano-sized hydrogen storage system increases efficiency




hydrogenation forms a mixture of lithium amide and hydride (light blue) as an outer shell around a lithium nitride particle (dark blue) nanoconfined in carbon. nanoconfinement suppresses all other intermediate phases to prevent interface formation, which has the effect of dramatically improving the ...



tesla's new solar energy station will power hawaii at night




the kapaia project is a combination 13mw solarcity solar farm and 53mwh tesla powerpack station on the island of kauai. in partnership with the kiuc (kauai island utility cooperative) the project will store the sun's energy during the day and release it at night. the station (along with kauai's othe...



smart meters might not be so smart




professor frank leferink began investigating the issue after hearing rumors that the devices were wildly overestimating power use. the grumblings seem to have merit, since some of the meters that were tested claimed that energy use was 582 times higher than the reality. it's bad hardware, rather tha...



apple’s supplier clean energy program hits japan, includes large floating solar




apple has long been committed to using renewable energy for its own operations, and in 2015 extended that goal to its suppliers, starting with china. in its 2016 supplier responsibility report, the company said that its energy efficiency program had reduced carbon emissions by more than 13,800 metr...
