The last major problem of renewable power is energy storage for off-production times. The sun may go down at night, but our electricity demand continues. Towards solving this problem, EnerVault has created a 250-kilowatt iron-chromium redox flow battery
at a demonstration storage project
in California’s Central Valley.
One of the advantages of a flow battery is that the energy capacity can be expanded by installing larger tanks of the active material. Also, flow batteries are relatively inexpensive per kilowatt-hour compared to lithium-ion batteries and can provide power for multiple hours.
At less than $250 per kilowatt hour, redox flow batteries are cost comparable with gas-fired peaking power plants and are logical companions to renewable power generation.
While Google's previous self-driving vehicles have been either a converted Toyota Prius or a Lexus SUV, their new prototype
uses a new self-manufactured design
that looks like a golf cart.
Unlike previous models, these cars won't have human drivers monitoring them at all times. Google said the cars can detect objects up to 200 yards away in all directions and adjust their speed, turns and braking accordingly.
- No steering wheel or pedals
- Emergency stop button
- Top speed of 25 MPH (40 KPH)
- 2 seats
- Electric drive
The corporate overlords of SandForce SSD controllers have changed hands
again. Seagate, who was missing an SSD controller of its own, will become the new home. The following list gives a brief history of the numerous mergers involved:
- 1999 - HP's non-computing products division spun out as Agilent
- August 2005 - Agilent semiconductor products group spun out as Avago
- January 2012 - SandForce sold to LSI ($370 million)
- 2014 - LSI sold to Avago ($6.6 billion)
- May 2014 - Avago SSD division sold to Seagate ($450 million)
Because of easy licensing and not being tied to a particular NAND manufacturer, SandForce SSD controllers are very popular and have found their way into many product lines
- Intel 520, 530, 535, 330, 335
- Kingston HyperX, HyperX 3K, SSDNow E100, SSDNow KC100, SSDNow V+200, SSDNow V300
- Corsair Force Series
- OCZ Vertex 3, Agility 3, RevoDrive
- And many others...
Intel plans to offer a consumer grade 3D printed robot
for $1600 later this year. Jimmy, a desktop robot
, will include an Intel chip and be programmable using open source tools.
The hardware designs will be freely available online, allowing anyone with access to a 3-D printer to generate and assemble the basic parts.
The grand vision is to lower the barrier of entry to robotics.
Concerns over errors
in health articles on Wikipedia have caused some scientists to warn against using
the free encyclopedia to self diagnose medical conditions.
Most Wikipedia articles representing the 10 most costly medical conditions in the United States contain many errors when checked against standard peer-reviewed sources. Caution should be used when using Wikipedia to answer questions regarding patient care.
After several rumors
this month, Apple
and Beats Music
officially confirm a buyout
of the streaming music service
for 3 billion.
Despite rumors that Apple was only interested in Beats Music in an effort to boost a decline in iTunes numbers, the deal includes both the hardware and the streaming software sectors of Dr. Dre's business. And it's Apple's largest purchase ever.
For a monthly subscription of $9.99, users of the service can stream music from a library of over 20 million songs.
A federal appeals court yesterday held that copyright holders may not abuse the legal process to obtain the identities of thousands of Internet users.
The plaintiff in this case, AF Holdings, sought the identities of more than 1,000 Internet users that it claims are linked to the illegal downloading of a copyrighted pornographic film.
, American Civil Liberties Union, the ACLU of the Nation's Capital, Public Citizen, and Public Knowledge all came to the defense and won a crushing blow
against the copyright holder.
The upcoming car manufacturer received an unsolicited B- credit rating
from Standard & Poor due to "considerable uncertainty" about its long-term prospects. The rating, six levels below investment grade, was derived independently of Tesla and comes after over $2.3 billion was successfully raised by the company in March to fund a new battery factory.
Shares in Tesla have risen 41 percent this year.
The Firefox OS reference device, the Flame
is now available for pre-order
To standardize the design, development, and testing of Firefox OS, Mozilla has partnered with a company called T2Mobile to manufacture, distribute, and update a Firefox OS reference phone called the Flame. Until now, there has been no “reference device” and the options for getting something through retail were limited.
The Flame will also be a great development and testing environment for third party app developers targeting Firefox OS and HTML5.
