I’m admittedly way behind on my grassroots mapping updates… but here some more photos from our grassroots mapping excursions.
In our March 27th excursion, we also got immensely helpful assistance from Charles Stewart, who is a kite enthusiast / expert / entrepreneur. I was pretty psyched with my first experience with kite photography, rather than balloons.
Mathew Lippincott also gave a super interesting demonstration of his solar balloon technique, using thin plastic which is heat sealed, and dyed with pigment. It uses the sun to heat, and the sunny but still cold weather was great for getting the temperature differential to get lift. It is also super cheap to make, and eliminates the biggest expense of our Mylar balloon design, which is helium. It was great to finally meet him and some other of the Public Laboratory for Open Technology and Science, PLOTS, founding members.
We got good photos that I haven’t seen yet, but when they get stitched together, I’ll update with a link.
