Dear Battery 9876 The overflow is necessary. In 2006, at the first trial in the Sahara I lost my whole trial. In that protoype was no overflow and I got 90 mm of rain in 10 minutes. That was 22 liters of water that went in 10 minutes through the central opening. . As the box was already full, all the water went through the central opening and washed all the trees out. That's how I learned that an overflow was necessary. regards Pieter

Dear Battery9876 The top has no zigzag to increase or decrease the condensation surface. It is designed this way in order to get gravity on a horizontal surface. This way enabling to collect the condensation film. kind regards Pieter

would it kill you to put some background music in?

Hello Polydynamix

All infographics have a version with and without music. You can find the difference in the title.

Dear Robbykube The Groasis waterboxx is actually very cheap. About 8 times cheaper than irrigation and you also have no energy costs, no maintenance costs, you use no scarse groundwater and once your tree grows, after one year, you use the box for the next tree. I am already doing trials in Africa with the Government of Kenya, of Morocco, soon in Tanzania and Ethiopia, and it is a matter of time before it is used on a larger scale.

Kind regards

- Regarding the shape of the cover, the bottom of the zigzag must have a funnel shape, but not necessarily the top. So maybe you could stretch the zigzag vertically all the way to the horizontal level of the top of the box. That would enable to have more surface and collect more condensation.

Best luck with your project.

Dear Peter,

Your invention is fantastic but I would make 2 suggestions:

-why have an overflow cap? Instead collect the extra water from inside by extending the wick to the top of the water line. When the tank is full the extra water goes through the wick. You can use a small hole in the wick at the level of the bottom of the tank to have the same feature as now.This could be useful in less dry places where rain would have a tendency to fill the tank, especially in the rain season in the tropics.

Would the trees eventually deplete the groundwater?

Amazing! I would love to work with you guys! I will be in touch in the near future.

I read about the Waterboxx in this month's New Yorker (Dec 2011). I'm currently travelling in Japan and hope to put it to work on my farm in an arid part of Australia. Keep up the good work Mr Hoff. It's people like you who change the world and improve other peoples lives.
