Sunfolding Simplified Solar Trackers
Using air bladder actuators to make a sun tracker for a solar panel. So should be simple valves, no heavy motors...

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.

Using the whole house/roof as a sun tracker is kinda interesting, when the interior walls are exposed to exterior lighting in the daytime, but sealing up at night for better insulation?

FLux Energy GS Home
Uh, I think they are proposing a setup where the mirrors are fixed on carts traveling on tubular concentric rails around the core collector tower, the idea being it is easier to tow the whole array (which has a fixed mirror orientation relative to the tower) to track the sun. They also propose using the tubular rails as a large distributed radiator. I don't understand why they want to integrate PV (and how would one do the power takeoff from the moving carts?), and why they aren't using a whole ring to make the cart towing easier?

Dynamic Eye - Pinpoint Glare Shielding
I don't know how well it would work, since in some ways having a black spot in your vision could be almost as distracting as having that burning sun spot in your eye...

Project Guest VM
SUn is trying to make a Xen compatible VM using just java, and no intermediate OS in the VM. About as close to a hardware implementation of java as can be expected, and could provide some interesting opportunities to streamline and optimize java workloads, maybe.
