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

A few weeks ago, Ford Motor Co. quietly announced that it was rolling out a new wrinkle to the powerful safety feature called stability control, adding even more lifesaving potential to a technology that has already been very successful.
It won't be too much longer and hardware design, as we used to know it, will be remembered alongside the slide rule and the Karnaugh map. You will need to move beyond those familiar bits and bytes into the new world of software centric design.
People who want to take advantage of solar energy in their homes no longer need to install a bolt-on solar-panel system atop their houses -- they can integrate solar-energy-harvesting shingles directing into an existing or new roof instead.
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.
