Polymath: Beamed propulsion doable now, and with it space solar power.
microLED's have parallel but non-coherent output, which may be servicable for use as a light beam source for beamed propulsion, aka laser launch

XCOM - X-ray communications research
Reusing x-ray position beacon development work as a simple transmitter. Can potentially punch through reentry plasma sheaths as well, and may be low power. Bandwidth isn't very high for now (mostly brute force morse at the moment)

IEEE Xplore - Investigation of the Piezoelectric Effect as a Means to Generate X-Rays
Hey, look at that, a solid state x-ray source using all sorts of neat tricks to make it compact and on-off. I wonder if this could be used as the source for the beam in that clean fusion bomb...

Research update: New way to store sun’s heat - MIT News Office
Rechargeable solar fuel of sorts? How fast are the kinetics on this? Energy density is something similar to Li-ion batteries so this isn't explosive levels of energy...

LED fiber optic display films on the way
I wonder if this could be reversed to concentrate disperse solar light onto a solar cell, like a Fresnel lens?

LaserMotive » About
Lasermotive trying to commercialize their power beaming technology with a move towards UAV remote power delivery. If an electric UAV can get power remotely, it cuts down substantially on the weight on onboard energy storage. One possible end result is LEO/GEO power satellites beaming power to military surveillance UAV's in remote areas (not useful for other applications since you have a giant laser from the sky shining on the UAV so it would be an easily identifiable target)

NTT DOCOMO: Press Releases - 20090511
Basically, for stereo users, you can assign spatial coordinates/directions for specific audio sources. SO, for a conference call, all the west people on your left ear, all the east coast people on the right ear. Probably can do tricks like also shifting to be more forward or rearward, or farther away.
