More windows is something every urban dweller wants, but in the summers all that sunlight can make your place sweltering. Double-glazed windows do a decent job of insulation, but researchers at the Polytechnic University in Madrid have done them one better with Intelliglass. The special windows feature a layer of circulating water sandwiched between the glass that absorbs heat, reducing a/c bills by an estimated 70%. Not yet ready for prime time, though they hope to have it on the market soon.

If you inserted pigment into the water, could you shade the windows?
