Fusion
NIF, as it's known, is a five-billion dollar, taxpayer-funded super laser project whose goal is to create nuclear fusion – a tiny star – inside a laboratory. But so far, that hasn't happened.
The facility, which began operating in 2009 after a decade of construction at a cost of almost $4 billion, points 192 football-field-sized lasers at one tiny capsule the size of a peppercorn and filled with hydrogen. It creates degrees of heat and pressure never before achieved in a lab.
Standing outside NIF's target chamber in 2008, about a year before NIF's dedication, Director Ed Moses called NIF "more far-out, and far cooler than anything in science fiction or fantasy."'

Conversion of climate change skeptic not likely to sway GOP - latimes.com
The article does not mention that we are at the peak of the 12 year
sunspot cycle. In 2007, at the low of the sunspot cycle, 100 years of
global warming temporarily vanished.
There has never been any dispute that CO2 emissions cause some global
warning. The dispute has been whether this would lead to disaster.
It took a hundred years for the temperature to rise 1 degree
Fahrenheit. After I did considerable searching on the on the
Internet, I found that even the most strong proponents of this theory
thought that the temperature would only rise 1 to 3 degrees over the
next 100 years. This is not disastrous, although maybe inconvenient,
and it gives us plenty of time to move to alternatives. The first
nuclear fusion power plant comes online in just 8 years.
I am deeply interested in this:

Google and others are starting to use Soldi Oxide fuels cells to power their data centers
‘For decades, experts have agreed that solid oxide fuel cells (SOFCs) hold the greatest potential of any fuel cell technology. With low cost ceramic materials, and extremely high electrical efficiencies, SOFCs can deliver attractive economics without relying on CHP. But until now, there were significant technical challenges inhibiting the commercialization of this promising new technology. SOFCs operate at extremely high temperature (typically above 800°C). This high temperature gives them extremely high electrical efficiencies, and fuel flexibility, both of which contribute to better economics, but it also creates engineering challenges.
Bloom has solved these engineering challenges. With breakthroughs in materials science, and revolutionary new design, Bloom's SOFC technology is a cost effective, all-electric solution.
Over a century in the making, fuel cells are finally clean, reliable, and most importantly, affordable.’

Fwd: methane microbes/Solar from any semi
From: larry.r.trout
'Microbes that convert electricity into methane gas could become an important source of renewable energy, according to scientists from Stanford and Pennsylvania State universities.
Researchers at both campuses are raising colonies of microorganisms, called methanogens, which have the remarkable ability to turn electrical energy into pure methane -- the key ingredient in natural gas. The scientists' goal is to create large microbial factories that will transform clean electricity from solar, wind or nuclear power into renewable methane fuel and other valuable chemical compounds for industry.'
http://www.sciencedaily.com/releases/2012/07/120727144534.htm
'A technology that would enable low-cost, high efficiency solar cells to be made from virtually any semiconductor material has been developed by researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. This technology opens the door to the use of plentiful, relatively inexpensive semiconductors, such as the promising metal oxides, sulfides and phosphides, that have been considered unsuitable for solar cells because it is so difficult to taylor their properties by chemical means.
"It's time we put bad materials to good use," says physicist Alex Zettl, who led this research along with colleague Feng Wang. "Our technology allows us to sidestep the difficulty in chemically tailoring many earth abundant, non-toxic semiconductors and instead tailor these materials simply by applying an electric field."'

Roger Ebert on the Higgs Boson
Wednesday, July 11, 2012
Re: God Particle
'They found the "God-Particle."
That was the headline in many of America's news media. It turns out that the name actually derives from substituting "God-particle" for "goddamn particle," the original name some scientists had given the elusive particle. But the media adopted the former nomenclature…
So, sincere congratulations to the physicists and other scientists who discovered the Higgs boson. We now think we have uncovered the force or the matter that gives us the four percent of the universe that we can observe (96 percent of the universe consists of "dark matter," about which scientists know almost nothing).'

The Higgs boson made simple
What good is it?
Particle physicists try to avoid forecasting the applications of an experimental advance before the actual advance is confirmed, but in the past, advances on a par with the discovery of the Higgs boson have had lots of beneficial applications, and some that are more questionable. The rise of nuclear power and nuclear weaponry is a prime example of that double-edged sword.
The discovery of antimatter is what made medical PET scanning possible, and antimatter propulsion could eventually play a part in interstellar travel, just like on "Star Trek." Particle accelerators have opened the way to medical treatments such as proton eye therapy — as well as advances in materials science, thanks to neutron scattering.
It's conceivable that the discoveries made at the Large Hadron Collider will eventually point to new sources of energy, Michio Kaku, a physicist at City College of New York, told me during a discussion of the LHC's promise and peril. And if the discovery of the Higgs leads to fresh insights into the fabric of the universe, it's conceivable that we could take advantage of the as-yet-unknown weave of that fabric for communication or transportation. Who knows? Maybe this is how "Star Trek" gets its start.

EV highway
I am thinking that a magnetic field would produce a drag on a vehicle. It would also affect non-electric vehicles.
I had a different thought that you could have a moving magnetic field that moves at 55 MPH. The field would pull vehicles, effectively making all vehicles electric.

RE: below two miles of ice...
The only reason that it is liquid water (I suppose) is that the tremendous pressure changes the state? Or ice simply floats on water?

‘In the coldest spot on the earth’s coldest continent, Russian scientists have reached a freshwater lake the size of Lake Ontario after spending a decade drilling through more than two miles of solid ice, the scientists said Wednesday…
Lake Vostok, named after the Russian research station above it, is the largest of more than 280 lakes under the miles-thick ice that covers most of the Antarctic continent, and the first one to have a drill bit break through to liquid water from the ice that has kept it sealed off from light and air for somewhere between 15 million and 34 million years.’
Isn’t this how a few horror movies start out.
I just hope we don’t release something our immune systems have never seen before J

Fwd: computer reading images in mind
'By monitoring the brain activity of people while they watched Hollywood movie trailers, researchers were able to recreate a moving picture similar to the real footage being played.
While the technology is not yet capable of reading our thoughts, it could eventually lead to ways of translating our dreams and memories onto screen.
If it is refined enough the method could even be used to explore the minds of stroke patients, experts said.
Researchers from the University of California, Berkeley, used MRI scanners to monitor the blood flow in people's brains as they watched films including Madagascar 2, Pink Panther 2 and Star Trek unfold on a screen.
After analysing how the brain's visual centre responded to on-screen movements, the scientists created a computer program which could accurately guess what the person was looking at.

Mind-reading research: the major breakthroughs
22 Sep 2011
When the researchers watched a second set of clips, this time Hollywood film trailers, the programme was able to produce an approximate version of what they were watching.
It did this by scanning a library of random YouTube videos, pulling out the most similar clips to what it guessed the person was watching, and blending them together.
Because the program's video library contains just 18 million seconds of footage – a relatively small amount – it is highly unlikely that any clip will be very similar to the real footage.
To combat this problem, the program averages together the 100 shots from the video library that it thinks are the best match.
The result is a blurry but continuous video in which the movements of the shapes on screen reflect the action in the genuine Hollywood trailer.
Prof Jack Gallant, one of the study's authors, said: "We're trying to reconstruct the movie that was seen by searching through a large library of completely different, random movies.
"This is a major leap toward reconstructing internal imagery. We are opening a window into the movies in our minds."'
