Here is a list of my projects. The majority of my projects relate to Science, Technology, and Engineering. Many of these projects are intended to help the developing world. I believe that the great majority of our problems (if not intangible, like social or political problems) can be resolved by solutions that do not require advanced forms of technology.
The Hydrautomat is a self-powered water pump that was developed by Thomas Gaskell Allen Jr in the 1920's. The device uses air and water pressure to lift water. It is 80% efficient in terms of the pressure used, and can pump water many orders higher than a Hydraulic Ram Pump.
