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

The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
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.
