    The hard fought Paris agreement to limit worldwide climate change, signed by 195 countries, went into effect less than a week before Donald Trump was elected president in a stunning upset.

    Unsurprisingly, the election has generated a tsunami of speculation, bordering on panic, among climate watchers. Trump has been outspoken in his opposition to the pact (he dismisses climate change as a “Chinese hoax”).

      MIT startup readies denser, safer lithium battery

      screen-shot-2016-09-23-at-3-43-57-pmThere are three main options to making better batteries —improve the anode, the cathode or the electrolyte.

      MIT spinout SolidEnergy Systems is preparing to market rechargeable lithium metal battery materials that offer a 2x energy density over same-size conventional lithium-ion batteries, a breakthrough achieved by swapping out a common battery anode material, graphite, for very thin, high-energy lithium metal foil, which can hold more ions — and, therefore, provide more energy capacity.

        Soon, the ubiquitous Li-ion battery will be as safe as … a lemon?

        May 31, 2016

        Lithium-ion batteries are popular because of their high energy density, but they’re temperamental. Exploding Li-ion batteries set off an epidemic of spontaneously combusting “hoverboards” last holiday season. Cheaply made batteries, or batteries that are mishandled – subjected either to high temperatures, or excessive charge-discharge cycles — are particularly dangerous.

          The battery chronicles (part 1): The perilous journey from lab to market

          May 23, 2016

          The race to build a super-battery that would outperform the internal-combustion engine is hardly along a superhighway; in fact it’s a road so twisty that many a promising battery technology has simply “spun out ” in the journey from laboratory to market.

          There are three main options to making better batteries —improve the anode, the cathode or the electrolyte.

            Microgrids get big boost from new energy legislation

            April 27, 2016

            Proponents of distributed power generation, or “microgrids,” have much to cheer about in the Energy Policy Modernization Act, passed by the Senate last week. As the first broad ranging energy bill in over 20 years, the new legislation is designed to respond to the nation’s rapid, and on-going, shift away from a complete reliance on fossil fuels.

            The bill recognizes three trends: Despite the fact that the US is now vying for leadership in production of oil and natural gas, wind and solar are quickly becoming cheaper than fossil fuels in some parts of the country; environmental regulations now in effect are forcing electric utilities to abandon coal-fired power in favor of alternative sources; and that the national grid is increasingly vulnerable to cyberattacks

            The legislation promotes a range of technologies and policies to make the grid more reliable and cyber-secure.

              Deadline for new power supply efficiency approaches

              November 18, 2015

              If you are building or planning to ship an electronic product next year that uses an external AC-DC power supply – the kind used with laptops, mobile phones, and industrial products– you will need to follow new power efficiency regulations for original equipment manufacturers (OEMs) that take effect February 10, 2016.

              New Department of Energy specifications call for greater energy efficiency from low-power, standard-voltage or low-voltage units.

                Smart City pilots target commerce, trade, sustainability

                By Richard Wallace | June 27, 2015

                Smart cities

                The Smart Cities concept, developing civil administration and social infrastructure by using new ‘cloud’ resources and assets, is gaining momentum in places like India and China where the ‘smart’ approach is being promoted as a way to close the technology gap between the past and the 21st century; between haves, and have nots.

                  Connected to smart meters, these solar panels can optimize output to power street lamps, electric vehicles, or feed the grid.

                  Nearly 20 million people have viewed the YouTube video below, “Solar FREAKIN’ Roadways!”, an over-the-top, Indigogo funding campaign pitch for a new approach to road building that uses hybrid technology panels that integrate LED lights, solar panels, and glass paving materials.
