You can take an elevator to the top of the Empire State Building, climb the Statue of Liberty, or peer over a martini from any number of rooftop bars in the city. But nothing will give you a view of Manhattan like the High Line.

Forget what Kermit said: It is easy being green. Nowadays, technological innovations that are helping us to lead more environmentally-friendly lives are coming at a steady clip. For evidence, just look to our vehicles. More and more, we’re trading gas-guzzling SUVs for cheerful hybrid cars, while electric car technology continues to blossom. But that’s not where the innovation ends. Inventors and engineers around the world are devising even more creative eco-friendly transportation solutions. From solar-powered vehicles to cars that biodegrade, these 10 rides are a glimpse into the not-so-fantastical future. Though many of them are still at the concept stage, we’re crossing our fingers that they’ll hit the streets (and skies and waters) soon. The future of transportation is so bright we gotta wear shades (or at least flip down the sun visor).
