Recently I wrote about Boeing’s all-electric satellite, which might launch later this year. Not to be outdone, apparently, Airbus Group flew the first all-electric aircraft late last month, called the E-Fan.
The E-Fan is an all-electric trainer aircraft made of composite material.
Leaving jet fuel behind means there is slight hitch: at the moment the the plane can fly for about an hour on a single charge. In any case this is a pretty big deal, because the largest aerospace and defense company in Europe and the world’s leading commercial aircraft manufacturer is backing it, is planning to build the trainer in series and is also planning to use what it learns to eventually develop a regional passenger model.

All-electric satellite propulsion is getting a boost from Boeing, which says it is “on track” to deliver the world’s first all-electric xenon-ion propulsion satellites in late 2014 or early 2015 after meeting key production milestones on its initial 702SP (small platform) satellites.
Boeing announced that it has completed static qualification testing, verification and assembly of the primary structures for 702SP inaugural customers ABS and Eutelsat, meaning the satellites are well on their way to launch. The initial contract for the satellite was signed in 2012 between Boeing and Satmex. Eutelsat acquired Satmex in January 2014.
The four 702SP communications satellites will launch in pairs, and once in orbit, they will be entirely powered and propelled by electricity, rather than relying on rockets. The first two are scheduled for launch aboard a single SpaceX Falcon 9 rocket early next year. An all-electric satellite dispenses with heavy chemical propulsion and uses electric propulsion not only to maintain itself stably in orbit over 15 years, but also to raise the satellite from where it is dropped into orbit by its carrier rocket to its final destination in geostationary orbit.

we’ve learned very little, except that fighting Big Oil and especially ExxonMobil is never-ending.
It’s been 25 years since the Exxon Valdez disaster. It’s a major reason for this blog’s existence; I’ve learned that ExxonMobil is bigger and more powerful than ever, and it’s grip on our lives is unrelenting.
ExxonMobil is an empire with it’s own set of rules; it does nothing that will weaken that empire.
A case in point from Friends of the Earth:
Despite the tragic damage to the ocean, wildlife and people, to say nothing of the score of spills since 24 March 1989, the oil industry and its supporters in Congress are pressuring the Obama administration to rescind a 40-year old ban on the export of U.S. crude oil. Lifting the ban would unleash a flood of oil tankers on our ports, significantly increasing the risk of another disaster.
“The Obama administration is turning a blind eye to the anticipated climate and environmental impacts of exporting fossil fuels like Bakken shale and Powder River Basin coal from the U.S., while at the same time touting a climate plan that claims to reduce our damaging impact here at home,” said Marcie Keever, Friends of the Earth’s Oceans and vessels program director. “On top of that, the administration may actually be considering lifting the ban on U.S. crude oil exports, which would exponentially increase climate change and the risks of more Exxon Valdez and Gulf oil spill disasters.”
An infographic, “Gateway to Extinction,” from Friends of the Earth and Healthy Planet/Healthy People details the potential threats posed by the proposed fossil fuel export terminal and pipeline projects in the Northwest. It also shows how lifting the ban would exponentially increase those threats.
The nation’s first offshore wind farm on the Pacific Coast cleared a crucial federal hurdle when Seattle’s Principle Power received approval to move forward on a commercial lease for the proposed $200 million, 30 Mw project.
Principle Power received the go-ahead last month from a Department of the Interior agency to lease 15 square miles of federal waters 18 miles from Coos Bay, Oregon. If the lease request gets final approval, the WindFloat Pacific project would anchor the first offshore turbines in federal waters on the West Coast. It also would be the first in the nation to use triangular floating platforms instead of single piles driven into the ocean floor. Read the rest of this entry »
Carbon capture and storage technologies designed to reduce carbon emissions get a better reception in the U.S. than in Europe, according to Technology Centre Mongstad (TCM), a Norwegian firm that tests CCS technology.
For one thing, there’s a lot more carbon to capture and store in the USA, and a lot of carbon emitting gas and coal fired plants still around. Read the rest of this entry »
Here’s a new twist on “gumming up the works:” regarding the safety issues confronting lithium ion batteries, maybe some gum them will help.
Washington State University researchers have developed a chewing gum-like battery material that could dramatically improve the safety of lithium ion batteries.
The WSU group, led by Katie Zhong, Westinghouse Distinguished Professor in the School of Mechanical and Materials Engineering, recently reported on their work in the journal, Advanced Energy Materials. They have filed a patent on the substance. Read the rest of this entry »
