Very high temperature (up to 1400C) molten silicon thermal energy storage. The kicker seems to be using concentrated solar power to melt, and a thermophotovoltaic system to recover power rather than a brayton cycle turbine using an intermediary fluid.

Insolight – Making solar energy affordable
Smart idea, using microlens plastic plate over CPV solar cells in a grid pattern under the plate, then shift the plate a little bit to track the sun. So basically you could do an artificial muscle actuator or MEMS to shift the plate, rather than some gigantic tracking heliograph CPV setup. Plate shift still limits tracking angles, but the cost is much cheaper.

Steam from the sun
So at 10x solar concentration, the surface cover composite sheet composed of the graphite flake thermal absorber/boiler coupled to an underlying buoyant porous carbon air foam, creates steam pretty well. I assume the insulating factor of the carbon air foam reflects more heat into the boiler region to improve efficiency, rather than letting heat travel through and warm the bulk water.

C7 design is interesting. Appears to be a concentrating solar PV rig, but single axis tracking? Makes anchoring the mirrors against wind easier.

Interesting collector design, based on on a blackbody cavity concept. Reduces costs since it doesn't use a vacuum tube receiver core, along with a low precision tolerant mirror reflector geometry. Seems to still require single axis tracking though, but 10 degrees is a lot easier to implement via ratchet mechanisms rather than continuous jackscrews.

Claiming a low cost double reflector mirror arrangement lets these guys do high concentration levels. Doesn't really solve the tracking problem, at first glance, but the same plastic shape trick could be used with a trough collector. Interesting that they use a clear plastic cover lens, but what about age or dust related degradation?
