The GREEN WHEEL from NASA technology can grow a portable garden in the darkest place in your house
The Green Wheel actually originates from a NASA project of a rotary hydroponic garden which could provide astronauts with fresh vegetables in spacecrafts.
But it was never converted into a functional device. Until recently, when DesignLibero used this invention to develop Green Wheel
Green wheel looks like a miniature ferris wheel provided with a hydroponic system, with which various plants can be grown in the aquatic environment. Plants roots are fixed to the outside of the circle, in a holder, and are rotated about the axis, over one hour, and at the bottom of the circle is a water tank and could contains nutrients too which can be absorbed by plants. At the same time, by rotation, all the plants are evenly exposed to light. Rotary Gardens can be adapted to different circles circumference, depending on the space you have available in your home, and the energy cost of such gardens is extremely low.
