Cold fusion reactor verified by third-party researchers, seems to have 1 million times the energy density of gasoline
“Andrea Rossi’s E-Cat — the device that purports to use cold fusion to generate massive amounts of cheap, green energy – has been verified by third-party researchers, according to a new 54-page report. The researchers observed a small E-Cat over 32 days, where it produced net energy of 1.5 megawatt-hours, or ‘far more than can be obtained from any known chemical sources in the small reactor volume’.”
The researchers couched their announcement and analysis with a lot of “weasel words”, probably bearing in mind the debunking of a previous “cold fusion” claim a few years ago.
However, at least one outfit involved is dumping all their petroleum holdings.
“Lockheed Martin, the US government’s largest contractor, says it has made a technological breakthrough in nuclear fusion power. The breakthrough will apparently allow Lockheed to build a 100-megawatt “compact fusion reactor” (CFR) that can fit on the back of a truck within 10 years. The reduced size — just 10 feet by 7 feet — will allow Lockheed to “design, build, and test the CFR in less than a year.” Clean, limitless power – from a compact generator, no less! – could give us airplanes that can stay in the air forever, reliable power for developing nations, fresh water through cheap desalination, and much, much more. If Lockheed really has cracked fusion power generation, then almost every aspect of modern life could be in for a revolution.”
Details are sketchy from the Lockheed “Skunk Works”. There is a feeling that the announcement was hurried because of Andrea Rossi’s E-Cat announcement (above). Lockheed never comes out and says this device is a certainty, just that they have “promising” breakthroughs.
If either announcement bears fruit, the future of the energy world could be both chaotic and promising.
Growing Crops in Martian or Lunar Soil September 18, 2014Posted by Al Philipson in Science and Science Fiction news.

That means future space colonizers may be able to farm their own food using local dirt. No hydroponics necessary.
If humans ever set up permanent bases on the Moon or Mars, we’ll need to be able to grow our own food there. To find out whether that’s actually possible, a team of scientists in the Netherlands planted 14 plant species in soils that simulate the Martian and lunar regolith. It turned out that the Martian soil simulant was better than some Earth soils for growing plant life, which is good news for astronauts and colonists.
Real Moon and Mars soils appear to contain the essential ingredients that plants need, except for reactive nitrogen (and an abundant water supply). Though the simulant soils closely match the composition and grain size of the real stuff, they also contain trace amounts of the nitrates and ammonium—the nitrogen-based compounds that plants love. So the simulant soil isn’t a perfect model.

“The team made no mention of the potential for weaponizing the new molecules to take on any Sith lords, but I suppose DARPA or any number of Jedi masters who follow Crave could come calling at any moment.”
… This new bond between photons could also have practical applications for contemporary chipmakers working to convert light into electric signals.
Most mind-blowing of all, … the breakthrough could one day lead to technologies that allow for the creation of complex 3D structures, like crystals, made out of light.

Brain-to-brain communication is finally possible September 9, 2014Posted by Al Philipson in Science and Science Fiction news.

But it’s interesting just the same.
“This is likely the closest that people have ever gotten to telepathy — although, admittedly, it’s still not very close. The researchers, in their PLOS ONE paper, called it the “realization of the first human brain-to-brain interface.”

For most, space exploration has been a fascination since adolescence; series like Star War and Star Trek, romanticizing the concept of far off planets and uninhabitable lands, filled with vast expanses of the darkness of space. Letting dreams take you beyond the clouds, aspirations of a career as an astronaut seem closer than before, but what about those who cannot make it through the rigorous process of entering NASA’s elite profession? Turns out you can buy your way off this planet; but there is still catch-you can’t come back.
As news of NASA’s plan to construct a permanent greenhouse on our local neighboring red planet Mars, other news comes from the red planet’s private sector-the newly funded “Mars One”. The independently crowd-funded Dutch company, Mars One is estimating that they can colonize Mars for human pilgrims as soon as 2023. And people are flooding in for a chance to explore the red planet.

What Constitutes a “Novel”? August 17, 2014Posted by Al Philipson in Escape from Earth.

When I was a young fellow, the average “novel” was 50,000 words. One of those narrow mass market paperbacks that used to be everywhere, but are rarely seen today. Any thing less was either a novella, an even shorter “novelette” (harken back to the old “Ace Doubles”), or a short story.
Somewhere along the line, the public started demanding larger books and the publishing industry complied. 100,000 words became the “standard” for a “novel”. 50,000 words was still technically a “novel”, but the industry wanted to put the fatter books on the shelves. A fat book had more of the spine showing and attracted buyers more easily than the thinner books of the past. And they could charge more for it. (more…)

Until recently, every physicist was laughing at this engine and its inventor, Roger Shawyer. It’s called the EmDrive and everyone said it was impossible because it goes against classical mechanics. But the fact is that the quantum vacuum plasma thruster works and scientists can’t explain why.
Shawyer’s engine is extremely light and simple. It provides a thrust by “bouncing microwaves around in a closed container.” The microwaves are generated using electricity that can be provided by solar energy. No propellant is necessary, which means that this thrusters can work forever unless a hardware failure occurs. If real, this would be a major breakthrough in space propulsion technology.
The entire idea that we have found something that seems to go against the the principle of conservation of momentum just seems crazy …. But the fact that it has worked for two independent parties can’t be denied.

On July 23, 2012, the sun unleashed two massive clouds of plasma that barely missed a catastrophic encounter with the Earth’s atmosphere. These plasma clouds, known as coronal mass ejections (CMEs), comprised a solar storm thought to be the most powerful in at least 150 years….
“If it had hit, we would still be picking up the pieces,” physicist Daniel Baker of the University of Colorado tells NASA….
A CME double whammy of this potency striking Earth would likely cripple satellite communications and could severely damage the power grid.
Analysts believe that a direct hit … could cause widespread power blackouts, disabling everything that plugs into a wall socket. Most people wouldn’t even be able to flush their toilet because urban water supplies largely rely on electric pumps.

A bill introduced Thursday by two members of the House Science Committee seeks to promote commercial asteroid ventures, including securing property rights for resources extracted from asteroids by American companies.
The American Space Technology for Exploring Resource Opportunities in Deep Space (ASTEROIDS) Act of 2014, HR 5063, was introduced Thursday by Reps. Bill Posey (R-FL) and Derek Kilmer (D-WA), members of the House Science Committee. The relatively short bill (about four and a half pages in the copy provided by Posey’s office late Thursday, since the bill is not yet posted on Congress.gov) would direct the president, through the FAA and other agencies, to “facilitate the commercial exploration and utilization of asteroid resources to meet national needs,” “discourage government barriers” to asteroid resources ventures, and promote the right of American companies involved in those activities to both explore and utilize asteroids as well as transfer and sell them.

Physicists reported this week the discovery of a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality.
“This is completely new and very much simpler than anything that has been done before,” said Andrew Hodges, a mathematical physicist at Oxford University who has been following the work.
The revelation that particle interactions, the most basic events in nature, may be consequences of geometry significantly advances a decades-long effort to reformulate quantum field theory, the body of laws describing elementary particles and their interactions. Interactions that were previously calculated with mathematical formulas thousands of terms long can now be described by computing the volume of the corresponding jewel-like “amplituhedron,” which yields an equivalent one-term expression.

This type of discovery could lead to all sorts of new “gee-whiz” stuff that can make science fiction stories come true. Those of us in the imagination business need to stay ahead of these things lest we be overtaken by reality.
