Cool Light on Hot Days: Fiber Optics Bring the Sun Indoors

A small mirrored disk with a small motor to track the sun can provided light indoors via fiber optics. This could have a large impact on electricity usage. "An estimated 35% of electricity used in the United States is expended on lighting interior spaces in daytime." Also, the indoor lights also generate heat, increasing air conditioning in the summer (though possibly reducing heating in the winter), but on the ac/summer side, it might help reduce risk of black and brownouts.
