According to 2011 Fukushima Nuclear Accident, we learned that lots of soil were collected but government have no method to deal with it because of it is dangerous.So robot is a better method to collect them. What's more, we find that plants can help speed up cleaning soil.In the regenerable area,there have been successful cases of enriching Sr137 by planting sunflower.
In response to the above three difficulties,this program proposes a self-growth,vertical planting to purify the soil while saving land-saving radiation-resistant towers.
After a few months, the towers gradually grow taller,and robots continues to collect the polluted soil. The seeds in the unit begin to germinate. The cleaning work is proceeding quietly and quickly.
