Unfortunately, there's also a thing called China.

Secret > patent.

I think Rossi probably does not have an acceptable theoretical basis for patent in any case. He would not be able to patent (even if the machine works) unless he can convince the patent office he really understands how it works and his explanation fits their understanding of things. I am skeptical on both counts (again, this is assuming it actually does work).

Real median income has been stagnant since around 1999, but it sure as hell hasn't been falling for two generations.

Heck, today's poverty line is about where the median income was in the 1950s (yes, adjusted for inflation).

Comment Sea level rise is not accelerating (Score 1) 429

In fact, it's actually flattening. Remember, this is supposed to be the hottest 10 years in the last 10,000 or whatever.

This may have to with additional Antarctic accretion, or a reversal of thermal expansion driven by the La Ninas. But it seems likely that the current sea level regime will not change a whole lot as long as we have an isolated polar continent -- we are still firmly in the grip of the Antarctica-driven glaciation cycles that began some tens of millions ago. So long term, I'm much more worried about massive new glaciers forming in, say, Canada and Norway, than whether we lose some in Greenland. Cold has generally been a much harsher foe to humankind than warmth.

Submission + - Wastewater May be 'Inexhaustible' Hydrogen Source (gizmag.com)

Zothecula writes: Currently, the world economy and western society in general runs on fossil fuels. We've known for some time that this reliance on finite resources that are polluting the planet is unsustainable in the long term. This has led to the search for alternatives and hydrogen is one of the leading contenders. One of the problems is that hydrogen is an energy carrier, rather than an energy source. Pure hydrogen doesn't occur naturally and it takes energy — usually generated by fossil fuels — to manufacture it. Now researchers at Pennsylvania State University have developed a way to produce hydrogen that uses no grid electricity and is carbon neutral and could be used anyplace that there is wastewater near sea water.

Submission + - Iranian National Drone Competition (suasnews.com)

garymortimer writes: "An impressive technology competition for a country under sanction.

The impetuous for this story is to give some apolitical insight into what Iranian academia et al, have been able to accomplishing under sanctions, and basically on their own.

That notion was conveyed to Ali when asking if he was interested in publicly sharing information about the contest and the entrants. The results of that request are as follows. The article has been gone through, a few of the photo’s have been cut and or resized to save space, as well as some changes made to sort out language continuity issues.

However, it has been left as true to the author’s original composition as possible, and we hope that you find it as enjoyable and informative as we did."

Submission + - Augmented Reality Aids Cybersquatting (wsj.com)

pbahra writes: "Layar, based in Amsterdam, is working on products that take augmented reality in a slightly different direction. You can now interact with any object, brand or anything really. It gets pretty complicated but the implications of what AR is doing are quite significant. For those not familiar with Layar, it is a platform that allows anyone to build an AR app. You use your mobile phone's camera to view the world and since your phone knows where you are and what you are looking at.The implications are profound. One of the most interesting apps that someone produced was a virtual tee-shirt shop. It was placed in the 20 most expensive shopping streets in the world, selling t-shirts. Stop and think about that for a minute. He built a virtual shop where a real one already existed. His shop was accessible via a mobile phone, the real one was accessible through, well, being real. That means that real space and virtual space can be owned by different people. There will be lawyers."

Submission + - Skynet becomes more real every day (washingtonpost.com)

Doofus writes: "An article in yesterday's Washington Post, A future for drones: Automated killing, describes the steady progress the military is making toward fully autonomous networks of targeting and killing machines.

Does this (concern|scare|disgust) any of you?

After 20 minutes, one of the aircraft, carrying a computer that processed images from an onboard camera, zeroed in on the tarp and contacted the second plane, which flew nearby and used its own sensors to examine the colorful object. Then one of the aircraft signaled to an unmanned car on the ground so it could take a final, close-up look.

Target confirmed.

This successful exercise in autonomous robotics could presage the future of the American way of war: a day when drones hunt, identify and kill the enemy based on calculations made by software, not decisions made by humans. Imagine aerial “Terminators,” minus beefcake and time travel.

The article goes on to discuss the dangers of surrendering to fully autonomous killing, concerns about the potential for "atrocities", and the nature of what we call "common sense"."

Comment Re:Both Polywell and MTF are just vaporware (Score 1) 389

Polywells already operate over 2K. The advantage of IEC is that temperature is essentially just the voltage of the well, so it's relatively easy to drive these machines at >10K.

The problem in IEC is confinement and density. In primitive IEC machines, there is a physical, spherical grid which drives collisions inside the grid. Because the ions hit the grid on at least 1% of passes, the losses are too great to achieve breakeven. Additionally, without compression density is low.

The Polywell is a basically an Elmore-Tuck-Watson IEC device with a shielded anode and magnetic compression of the virtual cathode, which may give the concept good enough confinement and density to drive net power. Additionally, the instabilities that plague tokamaks are avoided; the magnetic field has good curvature at all points.

Results for WB-8 (which has .8T magnets that will tell us a lot about scaling) are due in April 2011; at that point they decide whether to approve WB-8.1 which will attempt a p-B11 reaction.

The Navy contract has an option for an honest-to-God 100MW fusion reactor if results are good, so this thing is for real.

The advantage Polywell has over the ITER path is power density. Even if it works as well as advertised, the most advanced ITER follow-on design still has a power density a few orders of magnitude below light water reactors, meaning tokamaks will probably never compete with fission plants. Polywell, OTOH, operates at high beta, so it has a power density that makes it economically competitive.
