In fact, I imagine a system of self mooring barge made of recycled plastic that move slowly on the sea and catch plastic. Once plastic is on board, it has to be transformed in a re-usable product. The main energy of this bot will be electric, with solar panels...
I invite you to work on this project because,
first of all, we are all concerned, because we can t develop ourselves by killing everything on this Planet!
As a second point, it will be a Gold Rush when people will calculate the amount of free plastic available in the sea at a current market price of 200 euros by ton!!!
Let s Think...
I wait for your comments and ideas.
