How Steve Perlman's "Revolutionary" Wireless Technology Works - and Why its a Bigger Deal than Anyone Realizes

Before I get into the technical evaluation of Artemis's demo videos and much-ballyhooed claims in the press, let's cut through the hype:

  • Is this going to revolutionize wireless communications? While these demos alone don't necessarily demonstrate speeds beyond what is theoretically capable with LTE systems today, I ...

the Mythical Moore's Law for Solar Energy

It's understandable when people without any scientific or industry experience to talk about a Moore's Law for solar energy, but those who understand the technology should know better.  The reason it's so easy to fall into the trap of believing this is due to the superficial similarities ...
