Despite fovucsing on the LIDAR and Compas solution, cal earth were still curious about the feasbility of the earth funnel idea (see abstract presenation for detail.

I began prototyping the funnel solution to test its viability.

I reahched out to several labs and began the conversation about protoyping at their facility.

A net to quckly laser cut the funnel was exported from the Rhino model using the UnrollSrf tool

Laser cut profile:

(Black = cut, green = score)
The net will be cut from plywood to test its funtionality. Tabs with rivet holes have been added so that it can be assembled with minmal effort and tooling.

The corners have been rounded as Marco from CalEarth informed us of experiances in the past with bags tearing when similar devices have been used.
