Phil Ochs – Automation Song

People have been talking about automation since the 1950s. Has anything really changed since then? Technology has gotten more efficient, smaller, and able to process many more inputs quickly then in the past. But many jobs aren't easy to fully automate, due to the unpredictability of life. Computers are good at doing repetitive tasks accurately, but not very good at dealing with unexpected circumstances or widely varying materials and conditions. Microcontrollers only do what they are programmed to do, they can't do anything they aren't told to do.

"Dirt is probably the cheapest and simplest construction material out there, but it's not very strong compared to other choices. Luckily geotechnical engineers have developed a way to strengthen earthen materials with almost no additional effort - Mechanically Stabilized Earth (aka MSE or Reinforced Soil). If you look closely, you'll see MSE walls are everywhere. Thanks for watching, and let me know what you think!"

Chiller Types and Application Guide – Chiller basics, working principle hvac process engineering

In this video we look at chiller types and refrigerant compressor cooling technology within HVAC commercial refrigeration and provide an overview guide on when and where each chiller type is used. This covers air cooled chillers and water cooled chillers, centrifugal compressors, turbocor compressors, screw compressors, scroll compressors, reciprocating compressors, absorption chillers. We look at both vapor compression and vapor absorption chillers. How chillers work and the basic working principle of each.
