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

Parallax Inc. is known for developing the Basic Stamp microcontroller development board and educational accessory kits. In addition to developing a user-friendly educational platform to learn about 8-bit microcontrollers and software programming, it created a multicore 32-bit chip called the Propeller.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
