Science Community To Congress: Get Real On Climate Science Groups: Congress Must Accept Climate Change
July 5, 2016 (Inside Higher Ed)
“…[Thirty-one scientific societies have called on Congress] to accept that climate change is real. The letter comes at a time when many Republicans in Congress, including members of committees with responsibility for science spending and science policy, dispute the scientific consensus that climate change is happening…[Their letter reminded Congress multiple independent lines of evidence and the vast body of peer-reviewed science showed] climate change is occurring, and rigorous scientific research concludes that the greenhouse gases emitted by human activities are the primary driver…” click here for more
EV Sales Hold Steady Plug-In Electric Car Sales Report for June: more of the same
John Voelcker, July 5, 2016
“…[June plug-in electric car sales] continued at pretty much the same level as in May…[The Nissan Leaf electric car and the Chevy Volt plug-in hybrid ran even in 2015 but] the Leaf has now fallen substantially behind…[T]he Volt has averaged 2,000 sales a month while the Leaf has reached only half that…The Volt has now pulled slightly ahead in units sold since December 2010 (when both cars went on sale), and will likely cross 100,000 units sold in the U.S. next month…It's now at 98,558, versus the Leaf's 95,384. Silicon Valley maker Tesla Motors refuses to report monthly sales or break out its quarterly global deliveries by country, so we don't know how many cars it delivered last month in the U.S…[but it delivered 14,370 units from March through June, below its previous target of 17,000, though it claimed that it is now consistently producing 2,000 Model S and Model X electric cars a week…Ford's pair of Energi plug-in hybrids sold at a stronger pace last month than in several months prior…The only other plug-in electric car whose sales have exceeded 1,000 over the first six months is the Chevrolet Spark EV battery-electric minicar…[with] 1,779 vehicles…” click here for more
Breakthrough Ocean Energy Concept Hybrid nanogenerator harvests hard-to-reach ocean energy
Lisa Zyga, June 21, 2016 (PhysOrg)
“Energy from the ocean, or ‘blue energy,’ is [adequate to meet all of the world's energy needs but is underexploited because there is not yet any] effective way to harvest it economically and with reasonable efficiency…The main problem is that ocean waves are irregular and pass by at low frequencies, whereas most energy harvesters operate best with waves that have regular amplitudes and high frequencies…[Harvesting Broad Frequency Band Blue Energy by a Triboelectric–Electromagnetic Hybrid Nanogenerator from the Georgia Institute of Technology describes] a device that can harvest ocean waves in a very broad frequency range that encompasses almost all of the ocean wave energy spectrum, including the hard-to-reach low frequencies that are inaccessible to most harvesters…[It consists of an] electromagnetic generator (EMG), which has traditionally been the main approach for harvesting ocean energy [and is] well-suited for harvesting waves at high frequencies and fast rotation speeds [along with a] triboelectric nanogenerator (TENG), which has only recently been investigated for ocean energy applications [and] works better in the low-frequency range and at slower rotation speeds…” click here for more
