About

I'm a stonemason. Contributions to other fields include 1. the "pulser pump" (combining airlift pump and trompe in one device with no moving parts). See wikipedia for more information. 2. A way to design reflectors for unattended solar cooking. "The solar design T-square" 3. Various "dripper trackers" as low tech timers for moving large reflectors or solar panels to track the sun. 4. "Constriction airlift pumps" a type of airlift pump in small bore tubes that has greater efficiency, lower pressure needed and higher "lift to submergence ratio" than their competitors.
