Thought I would start a catch-all thread for interesting tech news that people stumble across that would be of interest, but maybe doesn't specifically apply to TVs, or PCs, or mobile phones, so it doesn't quite fit in those specific threads.

I'll start us off here...

MIT scientists create a graphene transistor, and get it to clock up to 427GHz. I really hope that graphene is the future of CPUs, it looks like an incredible material.

I'm tempted to say "/thread" too, but there's way way way more new articles every single day on nanowerk.com than a person can really read. So like, if someone else wants to pick out the best ones, I'd be pretty okay with that.

"A new wireless power technology has been revealed to the public for the first time today. It can charge devices through walls and obstacles via a router sized transmitter, based on an unlicensed spectrum used by Wi-Fi & Bluetooth. Technology coming to consumer devices such as smartphones in 2015."

This tech isn't really new, MIT researchers were powering a 60w lightbulb at 2-meters6-years ago. Really though, this sort of tech seems like it would be very bad for the power grid, radiating power for devices is massively wasteful. I also found this claim to be pretty questionable:

Cota offers the same kind of health risks that Wi-Fi in-home does

The amount of power output WiFi is microscopic compared to the output required to power and charge devices.

I think it's misleading, it offers the same kind of health risks as Wi-Fi except it's amplified by about 200x.

He mentions 1W power transmission. At 5v that only .2A which is nothing considering modern phones are now using 2.1A chargers for effective highspeed charging. This thing will not charge phones, it will only slow their draining.

Nope. Isn't even a semiconductor. It's way better as an interconnect material. Copper has a really bad time doing the interconnect job now, at least at the lowest metal layers, and as a result, something like 50% of power consumption in CPUs is now due only to these wires.
