Yes, Japanese scientists have successfully transmitted energy wirelessly, which is a key step to making solar power generation in space a possibility. The team at JAXA used microwaves to deliver 1.8 kilowatts of power – enough to run an electric kettle – through the air with pinpoint accuracy to a receiver 170-feet away.

In this GT segment, “legendary coder John Carmack continues his walkthrough on one of the most powerful gaming engines of all time: Tech 5.” Videos after the break.
It was demonstrated for the first time at the WWDC 2007 by John Carmack on an eight-core Apple Macintosh computer; however, the demo only utilized a single core and a single-threaded OpenGL implementation running on a 512 MB 7000 class Quadro video card. The engine is completely cross-platform, which means that there is no need to change anything in the engine code when switching platform
