Toyota shows off all solid state lithium superionic conductor based prototype battery - 0 views

  • last year the company described a prototype solid state lithium superionic conductor battery in an article in the journal Nature Materials that was based on a three dimensional framework. And just this month the company announced plans to introduce several new lines of hybrid and all electric vehicles over the next three years (after also announcing that the Prius hybrid now accounts for ten percent of all sales). The sticking point has been and remains, the batteries used in such vehicles which can account for up to half their cost to consumers.
  • The new battery, first described last year, uses Li10GeP2S12 in a layered three dimensional framework where cells are sandwiched together to create a stack of seven tiers with each having a voltage of four volts for a total of twenty eight at normal temperatures. The result, they say is a battery with five times the output density of previous varieties. To demonstrate its progress in refining the battery, the prototype was demonstrated recently to a group attending a green technology seminar as a power source for an electric scooter.

Lights out: The dark future of electric power - opinion - 12 May 2014 - New Scientist - 0 views

  • We tend to think of such events as occasional, inconvenient blips. But in fact they are becoming increasingly common, and will only get more frequent and severe. This is because our electricity systems are more fragile than is commonly supposed, and are getting frailer. Unless we act, blackouts will become a regular, extremely disruptive part of everyday life.
  • The vulnerability of such systems is demonstrated by the Italian blackout of 2003. The event began when a falling tree broke a power line in Switzerland; when a second tree took out another Swiss power line, connectors towards Italy tripped and several Italian power plants failed as a result. Virtually the whole country was left without power. It says something when a nation can be brought to a halt by two trees falling outside its borders.
  • We predict that blackouts will occur with greater frequency and greater severity due to trends in both electricity supply and demand. Supply will become increasingly precarious because of the depletion of fossil fuels, neglected infrastructure and the shift toward less reliable renewable energy. Demand, meanwhile, will grow because of rising populations and affluence.

  • Between 1940 and 2001, average US household electricity use rose 1300 per cent, driven largely by growing demand for air conditioning. And such demand is forecast to grow by 22 per cent in the next two decades.

    While not a green energy story, it is relevant.  The reality is that our demand for power is growing quicker than the volume of power we can produce.

'The Walking Dead' Star Norman Reedus Talks About Daryl Dixon's Relationship With Beth ... - 0 views

  • "At the end of a dark tunnel, she was the flicker of light when Daryl didn't think there was any light at that time anywhere. She gave him a little hope that there's something good left. But I think if he had any sort of romantic notions toward Beth, he didn't know what it meant. Just to have the little butterfly feeling for a second is something. It might have been like one tiny moth, but it was a flutter, and that was good enough for him," Reedus said.

Keurig Will Use DRM In New Coffee Maker To Lock Out Refill Market | Techdirt - 0 views

  • The plan was confirmed by Keurig's CEO who stated on a recent earnings call that the new maker indeed won't work with "unlicensed" pods as part of an effort to deliver "game-changing performance." "Keurig 2.0" is expected to launch this fall. French Press and pour-over manufacturers like Chemex have plenty of time to get their thank you notes to Keurig in the mail ahead of time as users are hopefully nudged toward the realization they could be drinking much better coffee anyway

South Korean Scientists Use E. Coli to Make Gasoline - Korea Real Time - WSJ - 0 views

  • Using genetically modified E. coli to generate biofuel isn’t new. U.K. scientists said in April they have developed a process under which the bacterium turns biomass into an oil that is almost identical to conventional diesel–a development that followed similar research by U.S. biotechnology firm LS9 in 2010. But the breakthrough this time is important because the reprogrammed E. coli can produce gasoline, a high-premium oil product that’s more expensive than diesel if the biofuel becomes commercially viable, according to Prof. Lee Sang-yup at the Korea Advanced Institute of Science and Technology. His team’s study was published in the international science journal Nature on Monday.
  • The significance of this breakthrough is that you don’t have to go through another process to crack the oil created by E. coli to produce gasoline. We have succeeded in converting glucose or waste biomass directly into gasoline,
  • only a few drops of the fuel per hour—making just 580 milligrams of gasoline from one liter of glucose culture.

World's Largest Solar Array Set to Crank Out 290 Megawatts of Sunshine Power - Scientif... - 0 views

  • Agua Caliente, the largest photovoltaic solar power facility in the world, was completed last week in Arizona.
  • ive million solar panels that span the equivalent of two Central Parks in the desert between Yuma and Phoenix. It generates 290 megawatts of power—enough electricity to fuel 230,000 homes in neighboring California at peak capacity.
  • The project, which cost a total of $1.8 billion to construct, received a million-dollar loan from the Loan Programs Office. Under its “SunShot” initiative (so-named in the spirit of president John F. Kennedy’s “moon shot” program), the DoE provides guaranteed loans to unproved ventures in solar power in the hopes of promoting innovation and making the technology more cost-effective.* Although Agua Caliente (owned by U.S. energy giant NRG Energy and partner MidAmerican Solar) is now the largest photovoltaic solar facility in the world, it probably will not hold that distinction for long. Other massive solar panel facilities, such as Antelope Valley Solar Ranch One in California’s Mojave Desert, are rapidly springing up across the Southwest.

ground hum in studio a/c - Gearslutz.com - 0 views

  • The $30 20 minute fix. Go to home depot and get a run of 12 gauge green wire, a pair of wire strippers and a pipe ground. Attach the pipe ground to the cold water pipe in your basement that comes from the street. Attach the wire to the pipe ground and run it into your studio. Turn off the circuit breaker and open the outlet(s) and remove the ground that is there and replace it with the wire from the basement. Turn on the circuit breaker. Done and done.
  • your best bet it to drive an actual ground rod (theyre pretty cheap) in your basement 10' deep or so ... then use the grounding techniques as above.... consider using braided wire as well, the larger surface area is better at 'grabbing' and grounding RFI
