If your electricity fails in a post-apocalyptic world, you
can use water pressure to generate electricity. Travis Lipstein and fellow
students in a mechatronics class at Colorado State University used a Tesla
turbine - based on the work of Nikola Tesla in the early 1900s - to turn water
into electricity. The water pressure forces a shaft in the turbine to rotate.
The rotating shaft is connected to a generator. The water flow around the turbine
is controlled by valves. The rotational speed is communicated to the user via a
LCD interface on the system's control panel, which lets the user know when
sufficient power is being generated by the turbine. Get Build Instructions | View
