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.

Looking at the Wikipedia talk page for Room-temperature superconductors, it seems like superconductors.org is a known crank/fraud site.

Dunno about fraud, didn't see em selling anything so hard to see who would be defrauded. Now as to crank? Oh yea. It gives it off in visible waves of zaniness from the page layout to the obviously fake endorsements.

Kinda looks like the superconductor version of a Perendev magnet motor, no?
That kind of stuff eggs on some people to make illusory videos to give hope the thing actually works, leading others to spend a lot of time pursuing futility.
Meanwhile, the author of the illusory video is hoping someone out there will give him big bucks for "patent rights" for his illusion. You already see these videos all over YouTube for overunity machines.
The illusionists plead "Fund me to build one for You!". You know as well as I what will happen next.
Mr. Moneybags gives Mr. Illusionist a good life in exchange for promises. This goes on as long as Mr. Moneybags keeps writing checks. He will keep receiving promises and "almost there". Until Mr. Moneybags gives up, highly frustrated, and by this time, the illusionist has enjoyed several good years at Mr. Moneybag's expense.
I know if I ever got one to actually work, the first thing I would probably do is replicate operating "toys" that demonstrate the principle and sell them through WalMart. One could no more patent that concept than try to patent fire.
A mass release would just make sure the cat is out of the bag big-time, and he's not going back in.
I have been taken in by several clever illusionists and spent several days building prototypes that never had a chance of working. My theoretical education told me all along it was futile to build it, but the salesmanship and "being closed-minded" taunts by the presenter egged on a lot of misallocation of my resources.
I have been quite intrigued with superconductivity, as I am puzzled as to why it happens at all. If this phenomena could be understood to a point we can fabricate high temperature devices, this will open up all sorts of possibilities for things beyond our wildest imaginings. I, for one, envision very powerful bidirectional motor/generator and capacitor units for cars to be used in such a fashion that every joule used goes to overcome air resistance... with absolutely no penalty for accelerating/braking. The car's energy would freely flow back and forth between kinetic and potential energy as seamlessly as watching a pendulum.

Funny enough, here's a quote from superconductivity.org/Links.htm:
Note: The link for Elsevier Science/Physica C has been removed. Elsevier Publishing has facilitated the theft of intellectual property belonging to Superconductors.ORG. And, despite repeated requests, refuses to redress the problem. Elsevier Science/Physica C is NOT a trustworthy source of superconductor information.
Also, this is bullshit: http://www.superconductors.org/woman.htm [superconductors.org].

No, that is merely a joke older than me and from your attitude, certainly older than you.
