Joe Eck's Superconductors.org is reporting the discovery of the 25th and 26th high-temperature superconductors. Sn9SbTe4Ba2MnCu15O30+ displays a critical transition temperature (Tc) near 136°C (276°F) and Sn10SbTe4Ba2MnCu16O32+ transitions near 141°C (285°F).
To grasp how exceptionally high these temperatures are, consider that 141 Celsius is warmer than the melting points of more than 45 different solder alloys.
These two new formulations resulted from expanding the unit cell of the 129C superconductor announced in March 2015. One extra Sn-Cu-O2 layer was added to reach 136C and two extra Sn-Cu-O2 layers were added to reach 141C.

One of the most highly populated niches for our best thinkers in physics is in superconductivity. If these "hot" superconductors were real, these people would be publishing about it in academic journals.
This guy is a talented maverick, an electronics engineer. Working alone, mavericks can sometimes be right and the world wrong, but 99/100 it's the other way around. I admire the passion, but unfortunately it's not solid science. Sites like Soylent that give these guys attention are what keeps them going, I think kindly, but to the detriment of science and to the gentleman himself. If soylent thinks it's smarter than all the most talented physicists who aren't buying into this, then yeah, go ahead and publish this. Otherwise, it's probably best to stick to mainstream science news from solid journals. There's still plenty to blow your mind in the real world.
On a semi-unrelated note, I sometimes like Wired, but they've been publishing jack articles that are like, hey, I can predict horse races, because science! And then changing headlines and not admitting the retraction: http://www.wired.com/2015/06/science-says-american-pharoah-wont-win-triple-crown/ [wired.com] . The original headline was something like, Science says American Pharoah won't win triple crown, and the new headline says American Pharoah Beats Science! As if. This is usurpation-of-science and post-race-coverup journalism.
For superconductivity, here's a nice primer: http://www.nature.com/news/2011/110720/full/475280a.html [nature.com]
As an example of news that Soylent might be interested in, related to physics and computing, try this:
