A new smoothie cart across from the Museum of Natural History in New York City will be powered by bicycles, says the NY Post. If you pedal the blender yourself you can get $1 off.

The smoothie truck will also have a gas tank full of cooking oil, solar panels, and there are plans to add wind power.

Apparently the pedaling discount is popular — about half of the cart’s customers take advantage of it.

“You’ll burn a few calories,” the owner said, “but not too many.”

We’ve eaten at the restaurant owned by these green smoothie cart people, Habana Outpost in Fort Green, Brooklyn, and it was very yummy indeed.
