I got stuck with the same issue in MATLAB for about a weekend. But suddenly, I found where the problem lies. Jesus!!? a whole weekend. You are not alone.

]]> Comment on Projects IV: Engineering’s Grand Challenges by Jed Rothwell http://www.bumscientist.com/blog/?p=547&cpage=1#comment-37 Jed Rothwell Sun, 08 Nov 2009 16:55:15 +0000 http://www.bumscientist.com/blog/?p=547#comment-37 You wrote "there is no such thing a cold fusion for electrical energy generation." That is correct, but on the other hand cold fusion is much closer to commercialization than plasma fusion, and it would probably cost far less to commercialize. At present it cannot be controlled, so cold fusion devices are usually 10 to 100 W (low power). Plasma fusion reactors produce 10 megawatts, but they run for only a fraction of a second, and it takes much more energy to make them run than they output. The plasma fusion record output energy was about 6 megajoules. Cold fusion cells run for months, sometime producing hundreds of megajoules. In recent years, Arata-style nanopowder cold fusion cell have been developed that run with no input power. They were confirmed at U. Kobe (published in Physics Letters A) and at the U.S. Navy (described at the recent conference in Rome, which was sponsored by the Italian ENEA - Energy Dept., and the Italian Physical Soc. and Chemical Soc.) Plasma fusion devices cost billions of dollars each; cold fusion devices cost a few hundred dollars. Plasma fusion can only be done at one or two facilities because it costs so much; cold fusion has been replicated by thousands scientists in hundreds of labs. They have published 3,500 papers, including 1,200 that I copied from the library at Los Alamos. If cold fusion can be made practical it will lower the cost of primary energy by a factor of a thousand or so; plasma fusion would probably be more expensive than today's sources of energy. So cold fusion is very promising. Unfortunately, funding for this research has been blocked by academic political opposition.

The “broken ffmpeg default settings detected” message is as a consequence of a revolt of x264 against FFmpeg because of its poor option system and lack of per-codec defaults.
