Cut the waste out of your first business
Five free modules for young people starting a business.
Written and taught by Grant Zhong, a senior at Mountain View High School.
I designed a drip irrigation kit that waters plants through gravity and printed every single part myself with a 3D printer. I've tested it at home in my own terrarium and have been selling the kit online through Farmish. The files are also free to download for personal use, and can be found at agrifuturelab.org/resources.
California's water, weighed from orbit
NASA's GRACE satellites measure water by its weight. As snow, rivers, soil, and groundwater gain or lose water, gravity over them changes by a tiny amount. In the Central Valley, outlined in yellow, the map goes red in every drought as farms pump groundwater out faster than rain and snow can put it back.
From 2019 to 2021 the valley lost groundwater about four and a half times faster than its average since 1962 (Liu and others, 2022).
