Superconductor room temp ambient pressure

I'm ready for my hover car and plasma rifle. Can we finally get into the future already?

If I understand correctly, this isn't as bad as it sounds.  While it is not a superconductor, it appears that it is still highly conductive.  That alone allows for a lot of applications of this material.

“And because these quasiparticles are controlled by light rather than an electrical current and gating, processing speeds in theoretical devices have the potential to reach femtoseconds—six orders of magnitude faster than the nanoseconds achievable in current Gigahertz electronics. All at room temperature.”

Thanks for the article link. However, it is important to note that, as of yet, though hopeful, applications have not been achieved.  There is proof of concept – at the quantum level, thus to have application in our human sized universe there is a sizing problem to be solved.  Note that the primary suggestion is within the semiconductor sector and also that light can have an impact and that the properties produce less heat – thus less light within the infrared wave length.  It is interesting that there was no references to radio waves (shortest light wave lengths) and their effects.  In short there is good news for some applications but this does not look to solve the sizing problem with products like medical MRI’s.

Also super expensive.  But I keep hoping that we can continue with breakthroughs that will lead us to a Star Trek type future instead of the Mad Max disaster.  

Musk will send up Starship next month.

Google has just announced 20 Gbps internet service.

The good ‘ole Issac vs. Ishmael family feud keeps goin strong though…

"To me, this is like a Wright brothers moment," said Walter de Heer, Regents' Professor of Physics at Georgia Techde, who led this development.  Interestingly, this newly built tech could be used to advance quantum computing. 

Is everything written by AI these days? Is this the future we leave to our posterity? I'm cringing at the thought.

Thanks again.  The links look promising.  Having worked in the semiconductor industry on of the problems with innovations of high conductivity and low voltage has been shielding from various outside electromagnetic radiation.

I have watched various developments of high conductivity over the years because the efficiency of electric motors is increased with better conductivity.   A big problem is that electric motors heat up with time in use and load.  There is a similar catch 22 with solar panels – because the sun is also a source of heat.

It looks like it will still be a while before we see industrial level production but any steps would be a good thing.
