The Citroen Eclipse concept from designer Vladislav Domanin delves into the power of nanotech to find a very interesting use of solar power, in a very unconventional way.The car employs nanoantenna, each of which has a width less than 1/25 of a human hair. These nanoantenna absorb the energy from the infrared range of the solar spectrum to generate power for the car. And since at night the earth itself releases a considerable amount of infrared waves that it absorbed during the day, the car can find power for itself for hours after sunset, thus not being dependent entirely on sunlight.

The concept’s body has three different layers, each of a different size. These layers are arranged to maximize the absorption of infrared waves from the sun, as well as from the earth. The car’s windshield is embedded with transparent solar cells to maximize energy absorption, and doors on the futuristic concept can retract into the body by employing magnetic fields.
