When you think about transportation innovations, highways probably aren't the first things that come to mind. But Dutch designer Daan Roosegaarde recently rolled out the first "smart" highway in the Netherlands -- and it utilizes glow-in-the-dark lane lines, interactive lights and smart road signs to make roadways safer and more sustainable. The skincare company Foreo has come up with a far less practical plan to lessen our need for streetlights: Increase the moon's reflectivity to make the night sky brighter. The bizarre idea calls for coating part of the moon in a reflective surface in order to increase the amount of light it reflects back to the Earth at night.
