Once for ever: Tesla was ethnic Serb from Croatia.
First “MotorBrain” prototype shown; lightweight electric motor system with no rare earth metals
MotorBrain prototype. Integrated unit is on the left, the motor core is at the right. Click to enlarge. The four partners in the European research project ”MotorBrain”—Infineon Technologies, Siemens, the Institute of Lightweight Engineering and Polymer Technology at the Technische Universit...
Antimony is a rare element (0.2 ppm), in its abundance comparable for instance to indium. There is 50x more Li in the lithosphere than Sb, so all this hype about replacing it by more abundant Na, thanks to Sb, is just nonsense.
Antimony nanocrystals as high-capacity anode materials for both Li-ion and Na-ion batteries
TEM image (false colored) of monodisperse antimony nanocrystals. (Photo: Maksym Kovalenko Group / ETH Zürich) Click to enlarge. Researchers from ETH Zürich and Empa have succeeded for the first time in producing uniform (monodisperse) antimony (Sb) nanocrystals (NCs). The nanocrystals posse...
Push it into water and rename into Enterprise.
Renault introduces ZE-ready concept with drone Flying Companion; targeting new markets
The KWID CONCEPT comes with a Flying Companion drone stored on the roof. Click to enlarge. Renault unveiled the KWID CONCEPT at the Delhi Auto Show—the first Renault concept car unveiled outside Europe. The KWID CONCEPT features a “Flying Companion”—a small drone that can be operated in one...
Could the use of EVs as taxis be suggested? Taxies generally make 7x more annual miles than family cars, and present an unique opportunity for general public to experience EV ride on the cheap. Take for instance Tesla-S. An 8000 cycles times 300 mi battery equals 2.4 million possible miles -- with the battery going flat after 8y due to degradation. No way even taxi could use it up more than 20-30%! In terms of emissions and economy each taxi is worth a bunch of private cars. The percentage of electric miles is vastly more important than the share of electric cars on the roads.
Researchers call for major change in US policies supporting plug-ins; failure of “mainstream consumer bias”
Although sales of plug-in vehicles (plug-in hybrid-electric and battery-electric vehicles, collectively PEVs) in the US climbed more than 80% in 2013 to more than 96,000 units (Tesla has not yet released its final figures) from 52,835 units in 2012 EDTA), the 2013 results still reflect a meagre...
"and vanadium is a rare earth metal". My, my... And its abundance is 136 ppm (compared to, for instance, 68 ppm for cooper).
Researchers propose new VO2 cathode material for aluminum-ion rechargeable battery
Schematic representation of the super-valent battery during charge/discharge process. Wang et al. Click to enlarge. A team from the University of Science and Technology Beijing is proposing a new super-valent battery based on aluminium ion intercalation and deintercalation. In an open acces...
Kit P: "The last 20 years of a nukes life it is producing power at < $2/MWh for even much smaller plants."
It's $0.02/kWh or $20/MWh. The rest is OK.
NREL study suggests cost gap for Western renewables could narrow by 2025
A new Energy Department study conducted by the National Renewable Energy Laboratory (NREL) indicates that by 2025 wind and solar power electricity generation could become cost-competitive without federal subsidies, if new renewable energy development occurs in the most productive locations. The...
In 2025 the world will be >80% nuclear as for instance present day France, the only country under the skies with no C-emissions problem. With nuclear <$10/MWh the Green craze will be just another craze in the long history of this crazy world.

GreenPlease, arseniding could be probably effected from the gaseous phase too by using arsine (AsH3) as a source of the element.
Researchers discover that adding arsenic to magnesium imparts corrosion resistance; “stainless magnesium”
Researchers in Australia and Wales have discovered that alloying additions of arsenic to magnesium can impart significant corrosion resistance. Their discovery, reported in the journal Electrochemistry Communications, could have implications for light-weighting in the aerospace, automotive and ...
A nonsense not only from thermodynamic point of view, but from the technological one too. Even if existing pipelines could not handle pure hydrogen, addition of several percent of H2 into NG would not substantially change parameters of the gas. The only thing that makes full sense is coal to liquids (or DME) by use of a nuclear generated hydrogen. Impressive work was already done in this direction exactly in Germany, but then came the green Talibans...
Audi opens power-to-gas facility in Werlte/Emsland; e-gas from water, green electricity and CO2
Audi’s e-gas plant. Click to enlarge. Audi has opened its e-gas plant in Werlte, making it the first automobile manufacturer to develop a chain of sustainable energy carriers. (Earlier post.) The Audi e-gas plant, which can convert 6MW of input power, utilizes renewable electricity for el...
Very pure iron could be extracted by room-temperature electrolysis of its aqueous solutions in very simple cells, so I can see no point in electrolysis of its molten salts.
MIT researchers identify viable anode material for molten oxide electrolysis for lower CO2 steel production
Researchers at MIT have identified inexpensive metal alloy materials that can serve as anodes for molten oxide electrolysis (MOE)—an electrometallurgical technique that enables the direct production of metal in the liquid state from oxide feedstock. Compared with traditional methods of extracti...
Not a single word about nukes, which provide 20% of US electricity and are 100% carbon free! In next 7y their world capacity will increase by 30%, it's fastest growing power-generating technology. Instead of that, all these wind, solar, bioenergy and fracking scams. Are lobbies really that strong, or what?
PCAST suggests 6 key components for climate change strategy to President Obama; adaptation and mitigation
The President’s Council of Advisors on Science and Technology (PCAST) released a letter to President Obama describing six key components the advisory group believes should be central to the Administration’s strategy for addressing climate change. The letter, responding to a request by the Presi...
"Have they sold their soul to Big Oil?"
Oil is a fuel, not sacrament.
Study finds technology cost of achieving European 2020 LDV CO2 targets more than offset by resultant fuel savings

By 2040 the average new car should do neither 147+ mpg nor 47 mpg but 15 kWh/100 km.
ExxonMobil: diesel will surpass gasoline as the number one global transportation fuel by 2020
