CNC Coolant Easy Guide to Machining Coolant
1. Chip Clearing: Spraying a cutting fluid at the cut helps move the chips out of the way of the cutter. Clearing chips minimizes recutting the chips. That means there are fewer chips for the cutter to remove and also that the old chips aren't getting sloshed around and slammed against the walls of the cut.

How a Wind Turbine Works
The largest turbine is GE's Haliade-X offshore wind turbine, with blades 351 feet long (107 meters) – about the same length as a football field. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

About ASME Engineering Services. A controversial and somewhat tragic figure, Richard Trevithick (1771 – 1833) is credited with inventing the first high-pressure steam engine and the first operational steam locomotive at the turn of the 19th century. Trevithick was born in the mining district of Cornwall, England in 1771.

How a Wind Turbine Works | Department of Energy
Turbines catch the wind's energy with their propeller-like blades, which act much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift.
