Magnets and energy: fundamental attraction?

Overview of magnets

Electric currents create magnetic fields. Moving magnets induce electric currents. These principles underpin 95% of global power generation, 50% of wind turbines, motors that comprise 45% of electricity use, heat…

Fans and blowers: costs and energy consumption?

Fans and blowers

…and fans/blowers must work to overcome larger total pressure drops. The simple energy economics are that power consumption (in Watts, aka Joules per second) is a product of air flow…

Boltzmann energy overview?

Cathode active materials
